Medical Corner – Vitamins
Vitamins are organic compounds which are needed in small quantities to sustain life. We get vitamins from food, because the human body either does not produce enough of them, or none at all. An organic compound contains carbon. When an organism (living body) cannot produce enough of an organic chemical that it needs, and has to get it from food, it is called a vitamin. There are two types of vitamins: fat-soluble and water-soluble vitamins. Both are needed for a healthy body.
Fat-soluble vitamins are stored in the fat tissues of our bodies, as well as in the liver. Fat-soluble vitamins are easier to store than water-soluble ones, and can stay in the body as reserves for days, some of them for months. Vitamins A, D, E and K are fat soluble. Fat-soluble vitamins are absorbed through the intestinal tract with the help of fats (lipids).
Water-soluble vitamins do not get stored in the body for long - they soon get expelled through urine. They need to be replaced more often than the fat-soluble ones. Vitamins C and all the B vitamins are water-soluble.
An important point to remember is that freezing, canning, and drying food takes away about one half of the vitamins potency. Eating as much fresh, raw vegetables, nuts, fruits, mushrooms (vitamin D) and dairy products makes for a healthier diet. If you are unable to eat a diet rich in the vitamins you need, talk to your doctor and, very important, take the proper dosage of a high-quality vitamin supplement. today.com/articles/195878.php
