Apart from macronutrients such as carbohydrates, protein and fats, the human body also require adequate amounts of vitamins and minerals. Vitamins are responsible for blood clotting, healthy skin, teeth, bones, neuromuscular functions and much more. A healthy well-balanced diet should provide sufficient quantities of vitamins, regardless of age, physical activity levels or gender. Individuals who regularly undergo intense training will have a natural increase in food intake and therefore the vitamins contained within. Some individuals however do supplement vitamin intake if the natural diet is deficient in them.
There are thirteen different types of vitamins identified and studied to date and if these there are two types; Water Soluble and Fat Soluble. Vitamins B complex and vitamin C are water soluble, vitamin A,D,K,and E are fat soluble. Scroll down to find out which food groups contain the major vitamins.
FREE RADICALS
Free Radicals are highly reactive molecules that are known to cause cell damage and thought to increase the aging process. They are also thought to contribute to heart disease, diabetes and cancer. Free radicals are found in environmental pollution, cigarette smoke, some medication and production of free radicals is even though to increase during exercise. Antioxidant enzymes are the body’s elaborate defence system against free radicals, in particular vitamin A-C and E are known antioxidant vitamins that protect against free radicals. Although exercise increases the production of these damaging free radicals, it also increases the levels of antioxidant defence system at the same time. There is research to suggest that a supplement of vitamin E reduces the production of free radicals during exercise, however the overall benefits are as yet unclear. Many years of research has failed to associate vitamin supplementation with athletic enhancement, where a balanced diet is present in fact some vitamins like C are known to be harmful if taken in excess. It is always recommended that one should maintain a well-balance diet full of fruits and vegetable to sufficiently maintain vitamin levels.
MINERALS,
Minerals provide structure for the formation for teeth, healthy bones and regulate acidity levels along with other bodily functions. Minerals also help muscular contraction and help to maintain a healthy rhythmic heart. They account for about 4% of a person’s total body mass. Depending on daily requirements, minerals are classed as TRACE or MAJOR. Calcium, Phosphorus, Magnesium, sodium and potassium are major minerals. Trace minerals include, chromium, selenium, zinc and iron.
Although the recommended daily allowance, RDA, of calcium is 800-1000mg for adults and 1200mg for adolescents, the typical intake in a western diet is around 500-700mg and has been known to be a low as 300mg per day. A calcium deficient diet and a lack of regular exercise is one of the greatest contributory factors to a high number of people being diagnosed with osteoporosis (brittle bone disease), in western society. Regular weight baring exercise promotes bone density.
The RDA for sodium is 1100-3300mg per day which equates to about 0.5-1.5 teaspoons of table salt. Sodium is found in abundance in processed foods and most people consume around 2 teaspoons from processed foods even in the absence of table salt for seasoning. There have been instances when pre-prepared meals have contained more than 6 times the RDA of sodium, and the same is true of some carbonated drinks. Exceeding the RDA can be potentially harmful with the exception of adding a small amount of sodium to sports drinks in hot weather (approximately 0.25-0.5 teaspoons per litre of water).
Some trace minerals such as iron are important in a balanced diet. Iron helps the blood to carry oxygen around the body and a deficiency in iron can lead to a person being fatigued even during mild exercise. Some research suggests that there is a greater demand for iron during intense training, however even in elite of athletes a supplement of iron is rarely required if the diet contains iron rich foods.
