The body’s biochemical processes need vitamins. In fact vitamins are extremely essential for the optimum working of those processes. Food has to be converted into energy and the body needs help to produce hormones and chemicals needed for the nerve system and blood cells. Only small quantities can be required, but these 13 vitamins and 18 minerals are crucial for everything within the body to function efficiently. They work to improve the body’s functioning and influence the body’s absorption abilities. The study of minerals and vitamins has been on for a fair period of time now and a lot is known about the roles of every in a body.
We also know a lot about what happens if too much or too little of any one is ingested. Research is an ongoing process to learn just as much as possible on the effects of those minerals and vitamins on the physiological functioning of the body. The Food and Nutrition Board of the National Research Council of the National Academy of Sciences are continuously reviewing the Recommended Dietary Allowances .All vitamins might be obtained straight from food with the exception of vitamins D, B5 and B7 that are obtained in part from various sources. B5 or Pantothenic acid might be absorbed by the body from a ten minute stint in the midday sun that will give an adult 50% of the necessary amount.
The remainder has to be absorbed from fatty fish like salmon and tuna or dairy products. A little is produced by the body by normal intestine bacteria. Minerals originate from the soil and water and are also found in plants and animals. Macro minerals are those that are needed by the body in large quantities. As magnesium, calcium and phosphorous. Micro minerals are those that are necessary in small quantities like fluoride, zinc, selenium, iron, and both together add up to18 in number. Preferably the required nutrition should come from the diet itself which suggests the diet has to be a balanced one.
But studies have shown that less than 1\/3 adults have the necessary 5 servings of fruits and vegetables. Individuals who need to consume more are kids and women that are pregnant, alcoholics and those who’ve diseases that would inhibit the assimilation of vitamins by the body. As also post menopausal women who now have to prevent osteoporosis. Older people have a tendency to have fewer calories than what’s their daily requirement. They depend on supplements for their vitamin deficiency. Supplements are being promoted as an insurance against poor dietary routines and these supplements are quickly becoming a habit and that is being stretched to include proteins. There are supplements for athletes that profess to improve their performance.
