Vitamins

Vitamins are essential substances, without which the body cannot thrive. When the diet is deficient in any of the vita­mins, certain disease conditions arise. The vitamins are called either by their technical names or, simply, by various let­ters assigned to them. Thus we speak of vitamins A, B, C, D, and so on. The public has been subjected to so much mislead­ing information about vitamins by the press, radio, and tele­vision that it would be well to give a few notes of re­liable scientific data about them.
