STAYING HEALTHY


What You Can Do To Stay Healthy



Evidence shows that some of the leading causes of death in the United States, such as heart disease, cancer, stroke, some lung diseases, injuries, and HIV/AIDS, often can be prevented by improving personal health habits. Eating right, staying physically active, and not smoking are a few examples of good habits that can help you stay healthy.

Eating Right

Eating the right foods and the right amounts of foods can help you live a longer, healthier life. Research has proven that many illnesses—such as diabetes, heart disease, and high blood pressure—can be prevented or controlled by eating right. Getting the nutrients you need, such as calcium and iron, and keeping your weight under control can help. Try to balance the calories you get from food with the calories you use through physical activity (select for more information about physical activity). It is never too late to start eating right. Here are some helpful tips.
Eat a variety of foods, especially:
Vegetables. Choose dark-green leafy and deep-yellow vegetables.
Fruits. Choose citrus fruits or juices, melons, and berries.
Dry beans (such as red beans, navy beans, and soybeans), lentils, chickpeas, and peanuts.
Whole grains, such as wheat, rice, oats, corn, and barley.
Whole grain breads and cereals.
Eat foods low in fat, saturated fat, and cholesterol, especially:
Fish.
Poultry prepared without skin; lean meat.
Low-fat dairy products.

Weight Control

Weighing too much or too little can lead to health problems. After age 45, many people gain too much weight. You can control your weight by eating healthy foods and being physically active. For more information, select the next section, "Physical Activity."
Ask your health care professional:
What is a healthy weight for me?
What are some ways I can control my weight?


Physical Activity

Research shows that physical activity can help prevent at least six diseases: heart disease, high blood pressure, obesity (excess weight), diabetes, osteoporosis, and mental disorders, such as depression. Physical activity also will help you feel better and stay at a healthy weight. Research suggests that brisk walking can be just as good for you as an activity such as jogging. Try to do a total of 30 minutes of constant physical activity, such as fast walking, most days of the week.
Before you start being physically active:
Talk with your doctor about ways to get started.
Choose something that fits into your daily life, such as walking, gardening, raking leaves, or even washing windows.
Choose an activity you like, such as dancing or swimming.
Try a new activity, like biking.
Ask a friend to start with you, or join a group.
Don't quit:
Make time for physical activity, start slowly, and keep at it.
If the weather is bad, try an exercise show on TV, watch an exercise tape in your home, walk in the mall, or work around the house.

Overcoming Depression

Everybody feels "down" or "blue" at times. But, if these feelings are very strong or last for most of the day, nearly every day, they may be due to a medical illness called depression.
The good news is that depression can be treated. But first you have to know you have it.
People do not always know the warning signs of depression. Some of these signs are listed below. If you have four or more, be sure to talk to your doctor about depression. If you print out this list, place a checkmark next to each sign that you have.
Warning Signs of Depression
Changes in the way you feel:
Feeling sad, hopeless, or guilty most of the time.
Feeling tired, low energy, or feeling "slowed down."
Crying a lot.
Having thoughts of suicide or death.
Changes in eating and sleeping habits:
Sleep problems, either too much or too little.
Changes in appetite or weight (up or down).
Changes in your daily living:
Loss of interest and pleasure in daily activities.
Problems making decisions or thinking clearly.
Treatment
The earlier you get treatment for depression, the sooner you will begin to feel better. The longer you wait, the harder depression is to treat.
Depression usually is treated with medicine, counseling, or medicine combined with counseling. Medicines for depression are not addicting or habit forming. They work for people with severe depression and may be useful for people with mild to moderate depression. Treatment works gradually over several weeks. If you do not start to feel better after this time, call your doctor. It may take some time to find what works best for you.

AYURVEDA: AN OVERVIEW


Ayurveda (Devanāgarī: आयुर्वॆद, the 'science of life') is a system of traditional medicine native to India, and practiced in other parts of the world as a form of alternative medicine.In Sanskrit, the word Ayurveda comprises the words āyus, meaning 'life' and veda, meaning 'science'.Evolving throughout its history, Ayurveda remains an influential system of medicine in South Asia. The earliest literature of Ayurveda appeared during the Vedic period in India. The Sushruta Samhita and the Charaka Samhita were influential works on traditional medicine during this era. Ayurvedic practitioners also identified a number of medicinal preparations and surgical procedures for curing various ailments and diseases.
Ayurveda has become an
alternative form of medicine in the western world, where patents for its medicine have been passed, and the intellectual property rights contested by Western and Indian institutions. Ayurveda is considered to be a form of complementary and alternative medicine (CAM) within the United States of America, where several of its methods—such as herbs, massage, and Yoga as exercise or alternative medicine—are applied on their own as a form of CAM treatment.


Overview


Ayurveda believes in 'five great elements' (Devanāgarī: पन्छतत्व‌; earth, water, fire, air and space) forming the universe, including the human body. Blood, flesh, fat, bone, marrow, chyle, and semen are the seven primary constituent elements (Devanāgarī: सप्तधातु) of the body. Ayurveda stresses a balance of three substances: wind/spirit/air, phlegm, and bile, each representing divine forces. The doctrine of these three Dosas (Devanāgarī: त्रिदॊश्)—vata (wind/spirit/air), pitta (bile) and kapha (phlegm)—is important. Traditional beliefs hold that humans possess a unique constellation of Dosas. In Ayurveda, the human body has 20 Guna (Devanāgarī: गुन, meaning quality). Surgery and surgical instruments are employed. It is believed that building a healthy metabolic system, attaining good digestion, and proper excretion leads to vitality. Ayurveda also focuses on exercise, yoga, meditation, and massage.
The concept of
Panchakarma (Devanāgarī: पन्छ्कर्म‌) is believed to eliminate toxic elements from the body. Eight disciplines of Ayurveda treatment, called Ashtanga (Devanāgarī: अश्ताग्), are given below:
Surgery (Shalya-chkitsa).
Treatment of diseases above the
clavicle (Salakyam).
Internal
medicine (Kaya-chikitsa).
Demonic possession (Bhuta vidya): Ayurveda believes in demonic intervention and—as a form of traditional medicine—identifies a number of ways to counter the supposed effect of these interferences. Bhuta vidya has been called psychiatry.
Paediatrics (Kaumarabhrtyam).
Toxicology (Agadatantram).
Prevention and building
immunity (rasayanam).
Aphrodisiacs (Vajikaranam).


Scientific evidence


As a traditional medicine, many Ayurveda products have not been tested in rigorous scientific studies and clinical trials. In India, research in Ayurveda is largely undertaken by the statutory body of the Central Government, the Central Council for Research in Ayurveda and Siddha (CCRAS), through a national network of research institutes. A systematic review of Ayurveda treatments for rheumatoid arthritis Yogaconcluded that there was insufficient evidence, as most of the trials were not done properly, and the one high-quality trial showed no benefits. A review of Ayurveda and cardiovascular disease concluded that while the herbal evidence is not yet convincing, the spices are appropriate, some herbs are promising, and yoga is also a promising complementary treatment.
Despite these misgivings, some ayurvedic products, mainly
herbs used for phytotherapy, have been tested with promising results. Turmeric and its derivative curcumin appears to have beneficial properties. Tinspora cordifolia has been tested. Among the medhya rasayanas (intellect rejuvenation), two varieties of sage have been been tested; one improved word recall in young adults, and another improved symptoms in Alzheimer's patients. In some cases Ayurvedic medicine may provide clues to therapeutic compounds. For example, derivatives of snake venom have various therapeutic properties. Many plants used as rasayana (rejuvenation) medications are potent antioxidants. Neem appears to have beneficial pharmacological properties as well.
Mitra & Rangesh (2003) hold that
cardamom and cinnamon are believed to stimulate digestive enzymes that break down polymeric macromolecules in the Human body. Research suggests that Terminalia arjuna is useful in alleviating the pain of angina pectoris and in treating heart failure and coronary artery disease. Terminalia arjun may also be useful in treating hypercholesterolemia. Azadirachta indica is believed to have immunopotentiating abilities and is used often as an anti-infective. It has been found to enhance the production of IL-2 and increase immunity in human volunteers by boosting lymphocyte and T-cell count in three weeks. Both black pepper and long pepper find application in Ayurvedic medicine in conjunction with ginger to form trikatu—a the traditional mixture. Trikatu has been suggested to increase appetite, promote the secretion of digestive juices, and cure certain gastric disorders—particularly Achlorhydria and Hypochlorhydria.


List of herbs and minerals in Ayurveda


Ayurveda (Devanagari: आयुर्वेद ) is a form of traditional medicine in use primarily in India. Ayurveda believes that various materials of vegetable, animal, and mineral origin have some medicinal value. The medicinal properties of these materials are time tested and have been used for centuries in ayurvedic medicines to cure illness and/or help maintain health.
Ayurvedic medicaments are made from herbs or mixtures of herbs, either alone or in combination with minerals, metals and other ingredients of animal origin. The metals, animals and minerals are purified by individual processes before being used for medicinal purposes. Impurified materials are not allowed to be used as medicine.
The forms of Ayurvedic medicaments are:
Fresh juice of herbs
Quath (Malayalam: കഷായം
) : Crushed herbs, used as decoction or tea for internal and external uses
Churna : Fine powdered herbs, used as medicine with water or in food for internal and external uses
Taila : Herbs cooked in edible oil according to rules laid down for internal and external uses
Ghrat/Ghrit : Herbs cooked in clarified butter
Asav/Arista/Sura : a kind of light wine obtained from fermentation of herbs
Arka : A distillation of herbs
Rasausadhi/Kharliya Rasayan : Herbs mixed with metals, minerals and animal ingredients
Bhasma : Ashes
Parpaty : combinations of Metals, Minerals, Animal ingredients and Herbs
Kshar/Lavan/Salt/Drava : these are specially prepared medicaments
Guggula based medicaments
Lauha Bhasam : Mandoor Bhasam based medicaments
Avaleha/Modak/Paak/Prash : Herbs cooked in Jaggery or sugar
Bati/Gutika/Goli : Mixtures of medicines shaped in pills, pillules or tablets for ease of administration
Pralep/Anjan/Varti/Dhoop : Liniments, drops, paint, paste etc. for external uses

Smoking: Avoid it !!


Smoking causes numerous diseases and health problems, some fatal, among both smokers and non-smokers. For this reason, smoking is prohibited in a growing number of public places and a wide range of support services has been developed to help individuals quit smoking.


Avoiding a smoking habit

Many smokers say they started smoking before the age of 18, even though the law prevents anyone selling tobacco, cigarettes or cigarette papers to those under this age. Avoiding the temptation to smoke at an early age is therefore important to prevent you developing a habit.


Improving your health


In the UK one person dies from a smoking-related disease every four minutes. Smoking causes:
lung cancer (smoking causes over 80 per cent of all lung cancer deaths)
heart disease
bronchitis
strokes
stomach ulcers
leukaemia
gangrene
other cancers eg mouth and throat cancer


Using a support service


NHS Stop Smoking Services - smokers are four times more likely to quit by using NRT together with support from NHS Stop Smoking Services - compared with using willpower alone. Find your nearest service by:
visiting the NHS 'Giving up smoking' website (England and Wales only)
texting GIVE UP' and your full postcode to 88088
telephoning the NHS Smoking Helpline ()
asking your local GP practice, pharmacy or hospital
The Together programme is a government initiative, in England only, designed to help you quit smoking using a wide range of support materials.
The NHS Smoking Helpline () in England and Wales offers free practical advice about giving up smoking, as well as a free information pack, while in Scotland, Smokeline () provides free confidential advice and support
The 'Giving up smoking' website also offers people in England and Wales an Ask an expert service. The Smokeline website offers a similar private and confidential service in Scotland.

Vegetables and Fruits: Eat Plenty Everyday....


"Eat your fruits and vegetables" is one of the tried and true recommendations for a healthy diet. And for good reason. Eating plenty of vegetables and fruits can help you ward off heart disease and stroke, control blood pressure, prevent some types of cancer, avoid a painful intestinal ailment called diverticulitis, and guard against cataract and macular degeneration, two common causes of vision loss.
What does "plenty" mean? More than most Americans consume. If you don't count potatoes—which should be considered a starch rather than a vegetable—the average American gets a total of just three servings of fruits and vegetables a day. The latest dietary guidelines call for five to thirteen servings of fruits and vegetables a day (2½ to 6½ cups per day), depending on one's caloric intake. For a person who needs 2,000 calories a day to maintain weight and health, this translates into nine servings, or 4½ cups per day (2 cups of fruit and 2½ cups of vegetables).
Over the past 30 years or so, researchers have developed a solid base of science to back up what generations of mothers preached (but didn't always practice themselves). Early on, fruits and vegetables were acclaimed as cancer-fighting foods. In fact, the ubiquitous 5 A Day message (now quietly changing to Fruits and Veggies: More Matters) seen in produce aisles, magazine ads, and schools was supported in part by the National Cancer Institute. The latest research, though, suggests that the biggest payoff from eating fruits and vegetables is for the heart.

Countering Cardiovascular Disease

There is compelling evidence that a diet rich in fruits and vegetables can lower the risk of heart disease and stroke.
The largest and longest study to date, done as part of the Harvard-based Nurses' Health Study and Health Professionals Follow-up Study, included almost 110,000 men and women whose health and dietary habits were followed for 14 years. The higher the average daily intake of fruits and vegetables, the lower the chances of developing cardiovascular disease. Compared with those in the lowest category of fruit and vegetable intake (less than 1.5 servings a day), those who averaged 8 or more servings a day were 30 percent less likely to have had a heart attack or stroke. Although all fruits and vegetables likely contribute to this benefit, green leafy vegetables such as lettuce, spinach, Swiss chard, and mustard greens; cruciferous vegetables such as broccoli, cauliflower, cabbage, Brussels sprouts, bok choy, and kale; and citrus fruits such as oranges, lemons, limes, and grapefruit (and their juices) make important contributions.
When researchers combined findings from the Harvard studies with several other long-term studies in the U.S. and Europe, and looked at coronary heart disease and stroke separately, they found a similar protective effect: Individuals who ate more than 5 servings of fruits and vegetables per had roughly a 20 percent lower risk of coronary heart disease and stroke, compared with individuals who ate less than 3 servings per day.

Countering Blood Pressure

High blood pressure is a primary risk factor for heart disease and stroke. As such, it's a condition that is important to control. Diet can be a very effective tool for lowering blood pressure. One of the most convincing associations between diet and blood pressure was found in the Dietary Approaches to Stop Hypertension (DASH) study.
This trial examined the effect on blood pressure of a diet that was rich in fruits, vegetables, and low-fat dairy products and that restricted the amount of saturated and total fat. The researchers found that people with high blood pressure who followed this diet reduced their systolic blood pressure (the upper number of a blood pressure reading) by about 11 mm Hg and their diastolic blood pressure (the lower number) by almost 6 mm Hg—as much as medications can achieve.
More recently, a randomized trial known as the Optimal Macronutrient Intake Trial for Heart Health (OmniHeart) showed that this fruit and vegetable-rich diet lowered blood pressure even more when some of the carbohydrate was replaced with healthy unsaturated fat or protein.

Countering Cancer

Numerous early studies revealed what appeared to be a strong link between eating fruits and vegetables and protection against cancer. But because many of these were case-control studies, where people who already have a certain health outcome (cases) are compared to people who do not have that outcome (controls), it is possible that the results may have been skewed by problems inherent in these types of studies; people with illnesses, for example, often recall past behaviors differently from those without illness, which can lead to potential inaccuracy in the information that they provide to study investigators.
Cohort studies, which follow large groups of initially healthy individuals for years, generally provide more reliable information than case-control studies because they don't rely on information from the past. And data from cohort studies have not consistently shown that a diet rich in fruits and vegetables prevents cancer in general. For example, in the Nurses' Health Study and the Health Professionals Follow-up Study, over a 14-year period, men and women with the highest intake of fruits and vegetables (8+ servings a day) were just as likely to have developed cancer as those who ate the fewest daily servings (under 1.5).
A more likely possibility is that some types of fruits and vegetables may protect against certain cancers. A massive report by the World Cancer Research Fund and the American Institute for Cancer Research suggests that non-starchy vegetables—such as lettuce and other leafy greens, broccoli, bok choy, cabbage, as well as garlic, onions, and the like—and fruits "probably" protect against several types of cancers, including those of the mouth, throat, voice box, esophagus, and stomach; fruit probably also protects against lung cancer.

Vision Improvement

Eating plenty of fruits and vegetables also keeps your eyes in good shape. You may have learned that the vitamin A in carrots aids night vision. Other fruits and vegetables help prevent two common aging-related eye diseases—cataract and macular degeneration—which afflict millions of Americans over age 65. Cataract is the gradual clouding of the eye's lens, a disk of protein that focuses light on the light-sensitive retina. Macular degeneration is caused by cumulative damage to the macula, the center of the retina. It starts as a blurred spot in the center of what you see. As the degeneration spreads, vision shrinks.
Free radicals generated by sunlight, cigarette smoke, air pollution, infection, and metabolism cause much of this damage. Dark green leafy vegetables—such as spinach and kale—contain two pigments, lutein and zeaxanthin, that accumulate in the eye; these pigments are found in other brightly colored fruits and vegetables as well, including corn, squash, kiwi, and grapes. These two pigments appear to be able to snuff out free radicals before they can harm the eye's sensitive tissues.
In general, a diet rich in fruits and vegetables appears to reduce the chances of developing cataract or macular degeneration. Lutein and zeaxanthin, in particular, seem protective against cataract.

HEALTHY EATING PYRAMID


The healthy eating pyramid is a nutrition guide developed by the Harvard School of Public Health, suggesting how much of each food category one should eat each day. The healthy eating pyramid is intended to provide a better eating guide than the widespread food guide pyramid created by the USDA.
The new pyramid aims to include the most current research in dietary health not present in the USDA's 1992 guide. The original USDA pyramid has been criticized for not differentiating between refined grains and whole grains, between saturated fats and unsaturated fats, and for not putting enough emphasis on exercise and weight control. It also had been developed by the Department of Agriculture, not the Department of Health and Human Services, so has been alleged to be influenced by lobbyists working for the agriculture, meat and dairy industries. This accusation is somewhat substantiated by the often larger portions in USDA recommendations relative to World Health Organization and NHS recommendations.

Food groups

In general terms, the healthy eating pyramid recommends the following intake of different food groups each day, although exact amounts of calorie intake depends on sex, age, and lifestyle:
Daily exercise and weight control
At most meals, whole grain foods including oatmeal, whole-wheat bread, and brown rice;1 piece or 4 oz.
Plant oils, including olive oil, canola oil, soybean oil, corn oil, and sunflower seed oil; 2 oz. per day
Vegetables, in abundance 3 or more each day. Each serv. 6 oz.
2-3 servings of fruits; Ea. serv. = 1 piece of fruit or 4 oz.
1-3 servings of nuts, or legumes; Ea. serv. = 2 oz.
1-2 servings of dairy or calcium supplement; Ea serv. = 8 oz. non fat or 4 oz. of whole.
1-2 servings of poultry, fish, or eggs; Ea. serv = 4 oz or 1 egg.
Sparing use of white rice, white bread, potatoes, pasta and sweets;
Sparing use of red meat and butter.

OVERWEIGHT

Overweight is generally defined as having more body fat (adipose tissue) than is optimally healthy. Being overweight is a common condition, especially where food supplies are plentiful and lifestyles are sedentary. As much as 64% of the United States adult population is considered either overweight or obese, and this percentage has increased over the last four decadesA series of graphics from the Centers for Disease Control and Prevention (CDC) shows the trend in which the prevalence of obesity has increased in the U.S. during the past three decades: Obesity Epidemic: U.S. Temporal Trends 1985-2004 Excess weight has reached epidemic proportions globally, with more than 1 billion adults being either overweight or obese. Increases have been observed across all age groups.
A healthy body requires a minimum amount of fat for the proper functioning of the hormonal, reproductive, and immune systems, as thermal insulation, as shock absorption for sensitive areas, and as energy for future use. But the accumulation of too much storage fat can impair movement and flexibility, and can alter the appearance of the body.

Health-related implications

Animals can suffer from obesity as well. This German Shepherd dog is noticeably overweight.
While the negative health outcomes associated with obesity are accepted within the medical community, the health implications of the overweight category are more controversial. The generally accepted view is that being overweight causes similar health problems as obesity just to a lesser degree. Adams et al. estimated that the risk of death increases by 20 to 40 percent among overweight persons. and the Framingham Heart Study found that being overweight at age 40yrs reduced your life expectancy by three years.Flegal et al., however, found that the mortality rate for individuals who are classified as overweight (BMI 25 to 30) may actually be lower than for those with an "ideal" weight (BMI 18.5 to 25.
Being overweight has been identified as a cause of cancer, and is projected to overtake smoking as the primary cause of cancer in developed countries as cases of cancer linked to smoking dwindle.
Psychological well-being is also at risk in the overweight individual. Discrimination against fat persons is common socially and legally. This may affect their ability to find a mate or employment.

Causes

Being overweight is generally caused by the intake of more calories (by eating) than are expended by the body (by exercise and everyday living). Factors which may contribute to this imbalance include:
Limited physical exercise and sedentary lifestyle
Overeating
Poor nutrition
Genetic predisposition
Hormonal imbalances (e.g. hypothyroidism)
Metabolic disorders, which could be caused by repeated attempts to lose weight by weight cycling,
Eating disorders (such as binge eating)
Alcoholism
Stress
Insufficient or poor-quality sleep
Psychotropic medication (e.g. olanzapine)
Smoking cessation and other stimulant withdrawal



Treatment

A large number of people undergo some form of treatment to attempt to reduce their weight, usually either in an attempt to improve their health, to improve their lifestyle, or for cosmetic reasons. The generally recommended treatment for being overweight is a modified or controlled diet in conjunction with increased physical exercise. For those who are obese rather than overweight, more intensive therapies such as anti-obesity drugs and/or bariatric surgery are sometimes used.
Studies suggest that reducing calorie intake by itself (dieting) may have short-term effects but does not lead to long-term weight loss, and can often result in gaining back all of the lost weight and more in the longer term. For this reason, it is generally recommended that weight-loss diets not be attempted on their own but instead in combination with increased exercise and long-term planning and weight management.
The health benefits of weight loss are also somewhat unclear. While it is generally accepted that for significantly obese patients, losing weight can reduce health risks and improve quality of life, there is some evidence to suggest that for merely overweight patients, the health effects of attempting to lose weight may actually be more detrimental than simply remaining overweight. Moreover, for all individuals, repeatedly losing weight and then gaining it back (weight cycling or "yo-yo dieting"), is believed to do more harm than good and can be the cause of significant additional health problems. This is caused by the loss of more muscle than fat.
There is no healthy, short-term solution for solving obesity, or being overweight. Changes in lifestyle, such as more exercise or dieting, must be permanent changes.

ABOUT BODY BUILDING!!!!


Bodybuilding is the process of maximizing muscle hypertrophy. Someone who engages in this activity is referred to as a bodybuilder. In competitive bodybuilding, bodybuilders display their physiques to a panel of judges, who assign points based on their aesthetic appearance. The muscles are revealed through a combination of fat loss, oils, and tanning (or tanning lotions) which combined with lighting make the definition of the muscle group more distinct. Famous bodybuilders include Arnold Schwarzenegger, Lou Ferrigno, Franco Columbu, and current Mr. Olympia Dexter Jackson. As Alan M. Klein states in Little Big Men, “Bodybuilding is a subculture of hyperbole. In its headlong rush to accrue flesh, everything about this subculture exploits grandiosity and excess."

History



The "Early Years" of Western Bodybuilding are considered to be the period between 1880 and 1930.
Bodybuilding (the art of displaying the muscles) did not really exist prior to the late 19th century, when it was promoted by a man from Prussia (Germany) named Eugen Sandow, who is now generally referred to as "The Father of Modern Bodybuilding". He is credited as being a pioneer of the sport because he allowed an audience to enjoy viewing his physique in "muscle display performances". Although audiences were thrilled to see a well-developed physique, those men simply displayed their bodies as part of strength demonstrations or wrestling matches. Sandow had a stage show built around these displays through his manager, Florenz Ziegfeld. The Oscar winning 1936 film "The Great Ziegfeld", depicts this beginning of modern bodybuilding when Sandow began to display his body for carnivals. The role of Sandow was played by actor Nat Pendelton.
Sandow became so successful at flexing and posing his physique, he later created several businesses around his fame and was among the first to market products branded with his name alone. He was credited with inventing and selling the first exercise equipment for the masses (machined dumbbells, spring pulleys and tension bands) and even his image was sold by the thousands in "cabinet cards" and other prints.
Sandow was a strong advocate of "the Grecian Ideal" (this was a standard where a mathematical "ideal" was set up and the "perfect physique" was close to the proportions of ancient Greek and Roman statues from classical times). This is how Sandow built his own physique and in the early years, men were judged by how closely they matched these "ideal" proportions. Sandow organised the first bodybuilding contest on 14 September 1901 called the "Great Competition" and held in the Royal Albert Hall, London, UK. Judged by himself, Sir Charles Lawes, and Sir Arthur Conan Doyle, the contest was a huge success and was sold out and hundreds of physical culture enthusiasts were turned away. The trophy presented to the winner was a bronze statue of Sandow himself sculpted by Frederick Pomeroy. The winner was William L. Murray of Nottingham, England. The most prestigious bodybuilding contest today is the Mr. Olympia, and since 1977, the winner has been presented with the same bronze statue of Sandow that he himself presented to the winner at the first contest.
On 16 January 1904, the first large-scale bodybuilding competition in America took place at Madison Square Garden in New York City. The winner was Al Treloar and he was declared "The Most Perfectly Developed Man in the World". Treloar won a $1,000 cash prize, a substantial sum at that time. Two weeks later, Thomas Edison made a film of Al Treloar's posing routine. Edison also made two films of Sandow a few years before, making him the man who made the first three motion pictures featuring a bodybuilder. In the early 20th century, Bernarr Macfadden and Charles Atlas, continued to promote bodybuilding across the world. Alois P. Swoboda was an early pioneer in America and the man whom Charles Atlas credited with his success in his statement: "Everything that I know I learned from A. P. (Alois) Swoboda."
Other important bodybuilders in the early history of bodybuilding prior to 1930 include: Earle Liederman (writer of some of the earliest bodybuilding instruction books), Seigmund Breitbart (famous Jewish bodybuilder), Georg Hackenschmidt, George F. Jowett, Maxick (a pioneer in the art of posing), Monte Saldo, Launceston Elliot, Sig Klein, Sgt. Alfred Moss, Joe Nordquist, Lionel Strongfort (Strongfortism), Gustav Fristensky (the Czech champion), Ralph Parcaut, a champion wrestler who also authored an early book on "physical culture," and Alan C. Mead, who became an impressive muscle champion despite the fact that he lost a leg in World War I.

Preparation for a Contest

A bodybuilder posing on stage during competition
The general strategy adopted by most present-day competitive bodybuilders is to make muscle gains for most of the year (known as the "off-season") and approximately 3-4 months from competition attempt to lose body fat (referred to as "cutting"). In doing this some muscle will be lost but the aim is to keep this to a minimum. There are many approaches used but most involve reducing calorie intake and increasing cardio, while monitoring body fat percentage.
In the week leading up to a contest, bodybuilders will begin decreasing their water intake so as to deregulate the systems in the body associated with water flushing. They will also increase their sodium intake. At the same time they will decrease their carbohydrate consumption in an attempt to "carb deplete". The goal during this week is to deplete the muscles of glycogen. Two days before the show, sodium intake is reduced by half, and then eliminated completely. The day before the show, water is removed from the diet, and diuretics may be introduced. At the same time carbohydrates are re-introduced into the diet to expand the muscles. This is typically known as "carb-loading." The end result is an ultra-lean bodybuilder with full hard muscles and a dry, vascular appearance.
Prior to performing on stage, bodybuilders will apply various products to their skin to improve their muscle definition - these include fake tan commonly called "pro tan" (to make the skin darker) and various oils (to make the skin shiny). They will also use weights to "pump up" by forcing blood to their muscles to improve size and vascularity. Some may also gorge on sugar-rich candies to enhance the visibility of their veins, often considered a sign of high muscle-definition.

Strategy

Bodybuilders use three main strategies to maximize muscle hypertrophy:
Strength training through weights or elastic/hydraulic resistance
Specialised nutrition, incorporating extra protein and supplements where necessary
Adequate rest, including sleep and recuperation between workouts
Water is very important during and after a workout to prevent dehydration.

Weight training

Weight training causes micro-tears to the muscles being trained; this is generally known as microtrauma. These micro-tears in the muscle contribute to the soreness felt after exercise, called delayed onset muscle soreness (DOMS). It is the repair to these micro-trauma that result in muscle growth. Normally, this soreness becomes most apparent a day or two after a workout. However, as muscles become adapted to the exercises, soreness tends to decrease.


Nutrition for Body Builders


The high levels of muscle growth and repair achieved by bodybuilders require a specialized diet. Generally speaking, bodybuilders require more calories than the average person of the same weight to support the protein and energy requirements needed to support their training and increase muscle mass. A sub-maintenance level of food energy is combined with cardiovascular exercise to lose body fat in preparation for a contest. The ratios of food energy from carbohydrates, proteins, and fats vary depending on the goals of the bodybuilder.Carbohydrates play an important role for bodybuilders. Carbohydrates give the body energy to deal with the rigors of training and recovery. Bodybuilders seek out low-glycemic polysaccharides and other slowly-digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat rather than muscle, and which can waste energy that should be directed towards muscle growth. However, bodybuilders frequently do ingest some quickly-digesting sugars (often in form of pure dextrose or maltodextrin) after a workout. This may help to replenish glycogen stores within the muscle, and to stimulate muscle protein synthesis.
Protein is probably one of the most important parts of the diet for the bodybuilder to consider. Functional proteins such as motor proteins which include myosin, kinesin, and dynein generate the forces exerted by contracting muscles. Current advice says that bodybuilders should consume 25-30% of protein per total calorie intake to further their goal of maintaining and improving their body composition.This is a widely debated topic, with many arguing that 1 gram of protein per pound of body weight is ideal, some suggesting that less is sufficient, while others recommending 1.5, 2, or more.It is believed that protein needs to be consumed frequently throughout the day, especially during/after a workout, and before sleep.There is also some debate concerning the best type of protein to take. Chicken, beef, pork, fish, eggs and dairy foods are high in protein, as are some nuts, seeds, beans and lentils. Casein or whey are often used to supplement the diet with additional protein. Whey protein is the type of protein contained in many popular brands of protein supplements, and is preferred by many bodybuilders because of its high Biological Value (BV) and quick absorption rates. Bodybuilders usually require higher quality protein with a high BV rather than relying on protein such as soy, which is often avoided due to its claimed estrogenic properties.Still, some nutrition experts believe that soy, flax seeds and many other plants that contain the weak estrogen-like compounds or phytoestrogens can be used beneficially as phytoestrogens compete with this hormone for receptor sites in the male body and can block its actions. This can also include some inhibition of pituitary functions while stimulating the P450 system (the system that eliminates chemicals, hormones, drugs and metabolic waste product from the body) in the liver to more actively process and excrete excess estrogen.
Bodybuilders usually split their food intake for the day into 5 to 7 meals of roughly equal nutritional content and attempt to eat at regular intervals (normally between 2 and 3 hours). This method purports to serve two purposes: to limit overindulging as well as increasing basal metabolic rate when compared to the traditional 3 meals a day. However, this has been debunked as the most reliable research using whole-body calorimetry and doubly-labeled water finds no metabolic advantage to eating more frequently.

Dietary supplements

The important role of nutrition in building muscle and losing fat means bodybuilders may consume a wide variety of dietary supplementsVarious products are used in an attempt to augment muscle size, increase the rate of fat loss, improve joint health and prevent potential nutrient deficiencies. Scientific consensus supports the effectiveness of only a small number of commercially available supplements when used by healthy, physically active adults. Creatine is probably the most widely used performance enhancing legal supplement. Creatine works by turning into creatine phosphate, which provides an extra phosphorus molecule in the regeneration of ATP. This will provide the body with more energy that lasts longer during short, intense bits of work like weight training.

Rest

Although muscle stimulation occurs in the gym lifting weights, muscle growth occurs afterward during rest. Without adequate rest and sleep, muscles do not have an opportunity to recover and build. About eight hours of sleep a night is desirable for the bodybuilder to be refreshed, although this varies from person to person. Additionally, many athletes find a daytime nap further increases their body's ability to build muscle. Some bodybuilders take several naps per day, during peak anabolic phases.

Overtraining

Overtraining refers to when a bodybuilder has trained to the point where his workload exceeds his recovery capacity. There are many reasons that overtraining occurs, including lack of adequate nutrition, lack of recovery time between workouts, insufficient sleep, and training at a high intensity for too long (a lack of splitting apart workouts). Training at a high intensity too frequently also stimulates the central nervous system (CNS) and can result in a hyper-adrenergic state that interferes with sleep patterns.To avoid overtraining, intense frequent training must be met with at least an equal amount of purposeful recovery. Timely provision of carbohydrates, proteins, and various micronutrients such as vitamins, minerals, phytochemicals, even nutritional supplements are acutely critical.
It has been argued that overtraining can be beneficial. One article published by Muscle & Fitness magazine stated that you can "Overtrain for Big Gains". It suggested that if one is planning a restful holiday and they do not wish to inhibit their bodybuilding lifestyle too much, they should overtrain before taking the holiday, so the body can rest easily and recuperate and grow. Overtraining can be used advantageously, as when a bodybuilder is purposely overtrained for a brief period of time to super compensate during a regeneration phase. These are known as "shock micro-cycles" and were a key training technique used by Soviet athletes. However, the vast majority of overtraining that occurs in average bodybuilders is generally unplanned and completely unnecessary.

UNDERWEIGHT: CAUSES AND REMEDIES

The term underweight refers to a human who is considered to be under a healthy weight. The definition is usually made with reference to the body mass index (BMI). A BMI of under 18.5 is usually referred to as underweight. It is important to note that the BMI is a statistical estimate and some individuals classified as underweight may be perfectly healthy. In fact, caloric restriction may be a viable means of increasing the lifespan, and it can easily lead to a BMI of less than 18.5. This medical definition of underweight may differ from other uses of the term, such as those based on attractiveness.

Causes


The most common cause of a person being underweight is primarily malnutrition caused by the unavailability of adequate food, which can run as high as 50% in parts of sub-Saharan Africa and south Asia. The effects of primary malnutrition may be amplified by disease; even easily treatable diseases such as diarrhea may lead to death.
In the presence of adequate food resources, being underweight can sometimes be the result of mental or physical disease. There are hundreds of possible medical causes for excessive weight loss or a person being underweight. Some of the more prevalent include:
Poverty
Famine
Torture

Cancer or Cancer Treatment
Tuberculosis
Hyperthyroidism
Type 1 Diabetes
Anxiety and depressive disorders
Drug abuse
Inflammatory bowel disease
Malfunctioning digestive organs
Dental pain
Over-training (endurance sports)
HIV/AIDS
Genetics
Stimulant use
Naturally light weight.

Problems

The most immediate problem with underweight is that it might be secondary to, and/or symptomatic of, an underlying disease. Unexplained weight loss requires professional medical diagnosis.
Underweight can also be a primary causative condition. Severely underweight individuals may have poor physical stamina and a weak immune system, leaving them open to infection. According to Robert E. Black of the Johns Hopkins School of Public Health, "Underweight status ... and micronutrient deficiencies also cause decreases in immune and non-immune host defenses, and should be classified as underlying causes of death if followed by infectious diseases that are the terminal associated causes." People who are malnutrative underweight raise special concerns, as not only gross caloric intake may be inadequate, but also intake and absorption of other vital nutrients, especially essential amino acids and micronutrients such as vitamins and minerals.
In women, being grossly underweight can result in amenorrhea (absence of menstruation) and possible complications during pregnancy. It can also cause anemia and hair loss.
Underweight is an established risk factor for osteoporosis even for young people. This is a particular insidious consequence, because the affected persons do not notice the danger, they can feel fit and may be brilliant for example in endurance sports. After the occurrence of first spontaneous fractures the damage is often already irreversible.

How to Gain Weight ?

If an individual is severely underweight to the point where problems with his or her health develop, it may be necessary for the person to make a concentrated effort to gain weight. The treatment for an underweight individual is to increase the food energy intake so that more food energy is consumed than is being used as work. It is usually suggested that weight training is also to be undertaken to increase muscle mass.
If weight loss results from a disease, resolving the illness and consuming adequate calories can bring many underweight individuals to a healthy body weight.


DIETING AND ITS EFFECTS


Dieting is the practice of ingesting food in a regulated fashion to achieve or maintain a controlled weight. In most cases the goal is weight loss in those who are overweight or obese, but some athletes aspire to gain weight (usually in the form of muscle) and diets can also be used to maintain a stable body weight.

Types of dieting

There are several kinds of diets:
Weight-loss diets restricts the intake of specific foods, or food in general, to reduce body weight. What works to reduce body weight for one person will not necessarily work for another, due to metabolic differences and lifestyle factors. Also, for a variety of reasons, most people find it difficult to maintain significant weight loss over time — among individuals that have lost 10% or more of body weight, only 20% are able to maintain that weight loss for a full year.
Many professional athletes impose weight-gain diets on themselves. American football players may try to "bulk up" through weight-gain diets in order to gain an advantage on the field with a higher mass.
Individuals who are underweight, such as those recovering from anorexia nervosa or starvation, may adopt weight-gain diets which, unlike those of athletes, have the goal of restoring normal levels of body fat, muscle, and stores of essential nutrients.
Many people in the acting industry may choose to lose or gain weight depending on the role they are given.
As more cultures scrutinize their diets, many parents consider putting their children on restricted diets that actually do more harm than good. This is extremely harmful to a young child's health because a full and balanced diet (fats, carbohydrates, protein, vitamins, minerals, fiber, etc.) is needed for growth. A doctor should be consulted before putting any child on a specialized diet.
Research also shows that putting children on diet foods can be harmful. The brain is unable to learn how to correlate taste with nutritional value, which is why such children may consistently overeat later in life despite adequate nutritional intake.

Fat loss versus muscle loss

Weight loss typically involves the loss of fat, water and muscle. A dieter can lose weight without losing much fat. Ideally, overweight people should seek to lose fat and preserve muscle, since muscle burns more calories than fat. Generally, the more muscle mass one has, the higher one's metabolism is, resulting in more calories being burned. Approximately 14 kilocalories are burned per pound of muscle at rest. Since muscles are more dense than fat, muscle loss results in little loss of physical bulk compared with fat loss. To determine whether weight loss is due to fat, various methods of measuring body fat percentage have been developed.
Muscle loss during weight loss can be restricted by regularly lifting weights (or doing push-ups and other strength-oriented calisthenics) and by maintaining sufficient protein intake. According to the National Academy of Sciences, the Dietary Reference Intake for protein is "0.8 grams per kilogram of body weight for adults."
Those on low-carbohydrate diets, and those doing particularly strenuous exercise, may wish to increase their protein intake which is necessary. However, there may be risks involved. According to the American Heart Association, excessive protein intake may cause liver and kidney problems and may be a risk factor for heart disease.There is no conclusive evidence that moderately high protein diets in healthy individuals are dangerous, however; it has only been shown that these diets are dangerous in individuals who already have kidney and liver problems.

How the body gets rid of fat

All body processes require energy to run properly. When the body is expending more energy than it is taking in (e.g. when exercising), the body's cells rely on internally stored energy sources, like complex carbohydrates and fats, for energy. The first source the body turns to is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate (in total about 2000 kcal). 65% is stored in skeletal muscles and the rest in the liver. It is created from the excess of ingested macronutrients, mainly carbohydrates. When those sources are nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy. In this process, fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which can be used to make energy. The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system.
Fats are also secreted by the sebaceous glands (in the skin).

EXERCISE


Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health. It is performed for many different reasons. These include: strengthening muscles and the cardiovascular system, honing athletic skills, and weight loss or maintenance. Frequent and regular physical exercise boosts the immune system, and helps prevent diseases of affluence such as heart disease, cardiovascular disease, Type 2 diabetes and obesity. It also improves mental health and helps prevent depression.

Types of exercise

Exercises are generally grouped into three types depending on the overall effect they have on the human body:
Flexibility exercises such as stretching improve the range of motion of muscles and joints.Aerobic exercises such as cycling, swimming, walking, rowing, running, hiking or playing tennis focus on increasing cardiovascular endurance.
Anaerobic exercises such as weight training, functional training or sprinting increase short-term muscle strength.

Exercise benefits

Physical exercise is important for maintaining physical fitness and can contribute positively to maintaining a healthy weight, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system.
Frequent and regular aerobic exercise has been shown to help prevent or treat serious and life-threatening chronic conditions such as high blood pressure, obesity, heart disease, Type 2 diabetes, insomnia, and depression. Strength training appears to have continuous energy-burning effects that persist for about 24 hours after the training, though they do not offer the same cardiovascular benefits as aerobic exercises do.
There is conflicting evidence as to whether vigorous exercise (more than 70% of VO2 Max) is more or less beneficial than moderate exercise (40 to 70% of VO2 Max). Some studies have shown that vigorous exercise executed by healthy individuals can effectively increase opioid peptides (aka endorphins, a naturally occurring opiate that in conjunction with other neurotransmitters is responsible for exercise induced euphoria and has been shown to be addictive), positively influence hormone production (i.e., increase testosterone and growth hormone), benefits that are not as fully realized with moderate exercise.
Exercise has been shown to improve cognitive functioning via improvement of hippocampus-dependent spatial learning, and enhancement of synaptic plasticity and neurogenesis. In addition, physical activity has been shown to be neuroprotective in many neurodegenerative and neuromuscular diseases. For instance, it reduces the risk of developing dementia. Furthermore, anecdotal evidence suggests that frequent exercise may reverse alcohol-induced brain damage.
Physical activity is thought to have other beneficial effects related to cognition as it increases levels of nerve growth factors, which support the survival and growth of a number of neuronal cells.
Both aerobic and anaerobic exercise also work to increase the mechanical efficiency of the heart by increasing cardiac volume (aerobic exercise), or myocardial thickness (strength training). Such changes are generally beneficial and healthy if they occur in response to exercise.
Not everyone benefits equally from exercise. There is tremendous variation in individual response to training: where most people will see a moderate increase in endurance from aerobic exercise, some individuals will as much as double their oxygen uptake, while others will never get any benefit at all from the exercise. Similarly, only a minority of people will show significant muscle growth after prolonged weight training, while a larger fraction experience improvements in strength. This genetic variation in improvement from training is one of the key physiological differences between elite athletes and the larger population. Studies have shown that exercising in middle age leads to better physical ability later in life.

Targeted fat reduction

Spot reduction is a myth that exercise and training a particular body part will preferentially shed the fat on that part; for example, that doing sit-ups is the most direct way to reduce subcutaneous belly fat. This is false: one cannot reduce fat from one area of the body to the exclusion of others. Most of the energy derived from fat gets to the muscle through the bloodstream and reduces stored fat in the entire body, from the last place where fat was deposited. Sit-ups may improve the size and shape of abdominal muscles but will not specifically target belly fat for loss. Such exercise might help reduce overall body fat and shrink the size of fat cells.

Nutrition and recovery

Proper nutrition is at least as important to health as exercise. When exercising, it becomes even more important to have a good diet to ensure that the body has the correct ratio of macronutrients whilst providing ample micronutrients, in order to aid the body with the recovery process following strenuous exercise. Proper rest and recovery are also as important to health as exercise; otherwise the body exists in a permanently injured state and will not improve or adapt adequately to the exercise. Hence, it is important to remember to allow adequate recovery between exercise sessions. It is necessary to refill the glycogen stores in the skeletal muscles and liver. After exercise, there is a 30 minute window critical to muscle recovery. Before doing anything else, one should drink something for recovery. Liquids are ideal after exercise and there are several studies that show low-fat milk and chocolate milk as being effective recovery beverages because of its ideal 4:1 combination of carbohydrate and protein that fuels and replenishes our muscles the best. The above two factors can be compromised by psychological compulsions (eating disorders such as exercise bulimia, anorexia, and other bulimias), misinformation, a lack of organization, or a lack of motivation. These all lead to a decreased state of health.
Delayed onset muscle soreness can occur after any kind of exercise, particularly if the body is in an unconditioned state relative to that exercise.

Categories of physical exercise

Aerobic exercise
Anaerobic exercise
Strength training
Agility training
Sometimes the terms 'dynamic' and 'static' are used. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly.

DIETARY MINERALS


Dietary minerals are the chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen present in common organic molecules. The term "mineral" is archaic, since the intent of the definition is to describe ions, not chemical compounds or actual minerals.
Dietitians may recommend that minerals are best supplied by ingesting specific foods rich with the element(s) of interest. Sometimes minerals are ingested as mineral dietary supplements, the most common being iodine in iodized salt.
The dietary focus on minerals derives from an interest in supporting biochemical reactions with the required elemental components. Appropriate intake levels of certain chemical elements are thus required to maintain optimal health. According to nutritional experts, the requirements are met simply with a conventional balanced diet.


Essential minerals


Sixteen minerals are required to support human biochemical processes by playing roles in cell structure and function as well as electrolytes:
Calcium is needed for muscle, heart and digestive system health, builds bone, supports synthesis and function of blood cells. Dietary sources of calcium include dairy products, canned fish with bones (salmon, sardines), green leafy vegetables, nuts and seeds.
Chloride is needed for production of hydrochloric acid in the stomach and in cellular pump functions. Table salt is the main dietary source of chloride.
Cobalt - vitamin B12. See pernicious anemia.
Copper is required component of many redox enzymes, including cytochrome c oxidase.
Iodine is required for the biosynthesis of thyroxine. See also Iodine deficiency.
Iron is required for many proteins and enzymes, notably hemoglobin. Dietary sources include red meat, leafy green vegetables, fish (tuna, salmon), eggs, dried fruits, beans, whole grains, and enriched grains. See also iron deficiency (medicine).
Magnesium is required for processing ATP and for bones. Dietary sources include nuts, soy beans, and cocoa. See also magnesium deficiency (medicine).
Manganese is a cofactor in enzyme functions.
Molybdenum - xanthine oxidase and related oxidases.
Nickel - urease
Phosphorus is a component of bones (see apatite) and energy processing and many other functions.
Potassium is a systemic electrolyte and is essential in coregulating ATP with sodium. Dietary sources include legumes, potato skin, tomatoes, and bananas.
Selenium, a cofactor essential to activity of antioxidant enzymes like glutathione peroxidase.
Sodium is a systemic electrolyte and is essential in coregulating ATP with potassium. Dietary sources include table salt (sodium chloride, the main source), sea vegetables, milk, and spinach.
Sulfur - cysteine and methionine
Zinc is pervasive and required for several enzymes such as carboxypeptidase, liver alcohol dehydrogenase, and carbonic anhydrase

Malnutrition


Malnutrition is a general term for a medical condition caused by an improper or insufficient diet. It most often refers to undernutrition resulting from inadequate consumption, poor absorption, or excessive loss of nutrients, but the term can also encompass overnutrition, resulting from overeating or excessive intake of specific nutrients. An individual will experience malnutrition if the appropriate amount of, or quality of nutrients comprising a healthy diet are not consumed for an extended period of time. An extended period of malnutrition can result in starvation, disease, and infection.

Malnutrition is the lack of sufficient nutrients to maintain healthy bodily functions and is typically associated with extreme poverty in economically developing countries. It is a common cause of reduced intelligence in parts of the world affected by famine. Malnutrition as the result of inappropriate dieting, overeating or the absence of a "balanced diet" is often observed in economically developed countries (eg. as indicated by increasing levels of obesity).

Most commonly, malnourished people either do not have enough calories in their diet, or are eating a diet that lacks protein, vitamins, or trace minerals. Medical problems arising from malnutrition are commonly referred to as deficiency diseases. Scurvy is a well-known and now rare form of malnutrition, in which the victim is deficient in vitamin C.


Survivors of Mauthausen-Gusen concentration camp after the liberationCommon forms of malnutrition include protein-energy malnutrition (PEM) and micronutrient malnutrition. PEM refers to inadequate availability or absorption of energy and proteins in the body. Micronutrient malnutrition refers to inadequate availability of some essential nutrients such as vitamins and trace elements that are required by the body in small quantities. Micronutrient deficiencies lead to a variety of diseases and impair normal functioning of the body. Deficiency in micronutrients such as Vitamin A reduces the capacity of the body to resist diseases. Deficiency in iron, iodine and vitamin A is widely prevalent and represent a major public health challenge. An array of afflictions ranging from stunted growth, reduced intelligence and various cognitive abilities, reduced sociability, reduced leadership and assertiveness, reduced activity and energy, reduced muscle growth and strength, and poorer health overall are directly implicated to nutrient deficiencies. Also, another, although rare, effect of malnutrition is black spots appearing on the skin.

Hunger is the normal psychological response brought on by the physiological condition of needing food. Hunger can also affect the mental state of a person, and is often used as a metonym for general undernourishment.

According to the World Health Organization, hunger and malnutrition is the gravest single threat to the world's public health and malnutrition is by far the biggest contributor to child mortality, present in half of all cases.

EFFECTS: Mortality due to malnutrition
According to the World Health Organization, hunger is the gravest single threat to the world's public health.[2] According to Jean Ziegler (the United Nations Special Rapporteur on the Right to Food for 2000 to March 2008), mortality due to malnutrition accounted for 58% of the total mortality in 2006: "In the world, approximately 62 millions people, all causes of death combined, die each year. One in twelve people worldwide are malnourished. In 2006, more than 36 millions died of hunger or diseases due to deficiencies in micronutrients". The World Health Organization estimates that one-third of the world is well-fed, one-third is under-fed and one-third is starving. Every 3.6 seconds someone dies of hunger.
Hunger and malnutrition have an even bigger impact on children’s health than was previously thought. According to the World Health Organization, malnutrition is by far the biggest contributor to child mortality, present in half of all cases. Underweight births and inter-uterine growth restrictions cause 2.2 million child deaths a year. Poor or non-existent breastfeeding causes another 1.4 million. Other deficiencies, such as lack of vitamin A or zinc, for example, account for 1 million. According to The Lancet, malnutrition in the first two years is irreversible. Malnourished children grow up with worse health and lower educational achievements. Their own children also tend to be smaller. Hunger was previously seen as something that exacerbates the problems of diseases such as measles, pneumonia and diarrhea. But malnutrition actually causes diseases as well, and can be fatal in its own right. This is the impact The Lancet seeks to identify.

The Nutrition Challenge










Eating truly healthy foods in proper balance is a challenging task. Our fast-paced and hectic lifestyle compels us to sacrifice nutritional value of foods on a daily basis. Rather than eating those foods for their nutritional value we eat foods for reasons other than nutrition.

Taste: We usually choose foods for their taste, rather than their nutritional value.

Eating –Out: Our fast-paced modern lifestyle does not allow us to prepare nourishing meals all the time. We conveniently tend to eat-out, resulting in less control on the nutritional value of our meals.

Skipping Meals: Many of us do not stick to regular meal times and often skip breakfast or lunch. We try to make amends by snacking up or over-eating later. These are poor eating habits.

Processing: Much of the food we buy today has been processed. Frozen vegetables often contain 50% less vitamin C than fresh ones; polished rice can lose upto 90% of its original B-vitamin content.

Effect of lifestyle choices: Dieting, medication, birth-control pills, smoking, alcohol consumption, excessive coffee and tea intake are all lifestyle factors which rob our body of essential vitamins & minerals.
Different Nutritional Needs For Different Life-stages

Childhood: Nutrient needs increase throughout childhood for optimal physical and mental growth.


Adolescence: This is a phase of rapid growth, both physical and mental. During this lifestage, the need for protein, calcium, iron and Vitamin A, C, E and B is the greatest. Supplementation is especially beneficial during this stage, due to poor nutrition. Pregnant and lactating women: To maintain the health of the expecting mother as well as the newborn baby, adequate quantities of vital nutrients like calcium, iron and folic acid are needed.

Nutrient needs for the elders: Ageing impairs absorption of foods into the system; our dental health detoriate, while the intake of medicines increases. All this necessitates the increasing need for certain nutrients while decreasing the need for calories.

Who needs supplementation?

Anyone not eating a balanced diet consisting of at least five servings of fruits and vegetables a day, as well as whole grain, low fat dairy products and small servings of lean meat, poultry, fish or pulses may not be getting enough protein, vitamins and minerals. As we age, the inability to chew and ageing itself may make the absorption and utilization of certain nutrients more difficult. Problem nutrients for older people are vitaminC, D, B6, B12 and folic acid, as well as some minerals, including zinc. Women of childbearing age needs iron, folic acid and calcium daily. Supplementation is the best way to get enough iron and folic acid due to better absorption by the body than when found naturally in foods.

Teenagers, especially teenage girls, do not consume enough iron. Iron supplementation during adolescence can prevent a decline in their body’s iron stores. Children need extra nutrition for their growing bodies. Children can be given special chewables and tasty multivitamin and mineral supplements along with protein and vitamin drinks and shakes.

Vegetarians, who do not consume animal products, may not get enough protein, iron, vitaminB12, zinc and calcium. People on low calorie diets, and persons who are heavy drinkers or smokers, are likely to be deficient in their requirement of vitamins and minerals.
