Vitamin A is most important for good eyesight. But it is also important for general good health. Liver contains a large amount of vitamin A, but vitamin A is also found in fish, meat, milk, butter, and in some fruits and vegetables.
Vitamin B in fact consists of twelve different chemicals, which are found in eggs, cheese, butter, meal flour and vegetables. If a person does not have enough vitamin B in his diet, it may affect his whole body, particularly the skin, the nervous system and the heart. Deficiency in vitamin B results in a disease called beri-beri, a sort of disease in feet.
