Fat soluble vitamins
From Wikipedia, the free encyclopedia
It is convenient to divide the vitamins into a fat-soluble or water-soluble group. The fat-soluble vitamins, namely vitamins A, D, E and K, are mostly found in fatty foods and fish-liver oils are particularly rich in vitamins A and D. This means that a certain amount of fat is needed in the diet to help the body absorb these vitamins. Vitamins A and D are also found in human liver and if the diet contains more vitamin A or D than is immediately required the surplus is stored in the liver. Enough of these vitamins are stored in the liver of a well-nourished person to satisfy the body's needs for several months if they are absent from the diet. If the diet contains too much vitamin A or D, however, the surplus will accumulate in the liver and may be harmful. Such excessive intakes are less likely to result from over-eating than through over-enthusiastic use of vitamin pills or dietary supplements.
