maintain good health.. These vitamins, along with the essential minerals (micronutrients) promote good biochemical reactions within your body and within your cells. They helps to grow right, digest your food, make you more mentally alert and sound, help you to be resistant to infectious diseases and help your body to use carbohydrates, proteins and fats. Also, vitamins and minerals are catalysts in your body, which speed up or initiate chemical reactions.
The difference between vitamins and proteins you get from food is that you don’t burn up the vitamins, so you can’t use them for energy.
Because your body does not make most vitamins and minerals directly, you have to get them from food sources or from vitamin supplements. If you aren’t getting enough of a certain vitamin or mineral for a long period of time you can get a specific disease or condition related to vitamin or mineral difficiency. Usually this can be fixed when the vitamin or mineral is re supplied to your body.
There are two kinds of vitamins, fat soluble and water soluble. The ones that are fat-soluble can be stored in your body fat and also stored in certain organs such as your liver. The water-soluble vitamins do not get stored in your body in large amounts.
The vitamins that are fat soluble can be stored in your body for a long time. These dissolve in lipids and require bile in order to be absorbed. They are also stored in tissues, and if you have too many of them they can be toxic to you.
The water-soluble vitamins dissolve in water, so if you are cooking or washing, the vitamins might actually be washed out of the food. They are easily absorbed and excreted, and are not stored very much or often in your tissues. These vitamins are seldom going to reach toxic levels.
