Vitamins and the Body. Water-soluble: vitamin C and all B vitamins. Fat-soluble: A, D, E and vitamin K
The body can not themselves provide vitamins, why vitamins are vital substances. A vitamin is an organic compound required by an organism as a vital nutrient in limited amounts. The main task of vitamins is to regulate the uptake and digestion of food. There are periodically discovered new vitamins, but currently you have knowledge of 13 different vitamins, and each of them has a specific function. The word vitamin comes from vita (life) and amine (amino acid). If a deficiency in one of the food for a longer period of time will result in deficiency diseases. For example, children who lack vitamin D develop rickets and thereby get the soft bones and typically become bow-legged. And older may, by lack of vitamin D and sunlight developing osteoporosis. Without vitamins, no life. The need to vary from vitamins vitamin vitamins and may be from a few micrograms to several, milligrams per day.
Vitamins are vital organic molecules
Vitamins are typically divided into water soluble (Vitamin B1-9, B12 and C) and fat soluble (Vitamins A, D, K and K). The fat-soluble vitamins absorbed from the diet with fat and accumulate in body fat as opposed to water soluble to be applied to the body every day through food. Some vitamins can be toxic in large quantities, this is especially true of A and vitamin D supplements, but it's very rare that it occurs. For most of us there are enough vitamins in the diet that we eat, but for some it may be necessary with a grant. Some people think that vitamins can replace food or reduce the intake of food, but it is not correct. Vitamins are either calories, proteins, minerals, fat or water, but vitamins are necessary for proper absorption and utilization of these things. A kind of inputs. Lack of a single vitamin can bring the body out of balance. Therefore it is vital that we eat as varied as possible.
