Vitamins are a group of substances found in food. The body needs them for life and health. So naturally, many people are concerned with the question: Am I getting enough vitamins, and am I getting the right kind?
Even though very small amounts of each vitamin are enough for the needs of the body, the worry people have about vitamins has some basis. And this has something to do with their diet—the food they take in. A person eating a good variety of foods gets all the vitamins now known to be needed (with the possible exception of Vitamin D).
The problem is that there are many people who don’t choose foods wisely, don’t get enough variety, and don’t eat the basic foods they need to get their vitamins. So the answer to this question is: no extra vitamins are needed, providing you eat proper foods. In fact, many of the vitamins cannot be stored in the body, so when extra vitamins taken in, the body simply gets rid of them. It is even harmful to put too much of certain vitamins into the body. This has been found to be true of Vitamin A and D, when large amounts are taken in.
What foods supply what vitamins? Here is a quick general idea. Vitamin A, for the health of the eyes, skin, teeth, and bones, is found in green vegetables, fruits, eggs, liver and butter. Vitamin Bl which helps the nervous and digestive system and prevents certain diseases, is found in cereals, pork and liver. Vitamin B2 is found in milk, eggs, green vegetables and meats. Vitamin C, which helps bones and teeth, is found in tomatoes, certain fruits and vegetables. These are only a few of the most important vitamins the body needs.
