Did You Know? To help the cells in our bodies work properly, it is essential that we get a daily supply of vitamins. This link between vitamins and good health was made in the early 1900s by the Polish biochemist Casimir Funk. Funk was studying beriberi, a disease that damages nerves, when he discovered an organic compound that prevented this illness. He named the compound vitamine, or "life amine," a name that stuck even though most vitamins do not include the type of chemical called an amine. Today we know that vitamins help keep our bodies strong and healthy, in addition to preventing a variety of illnesses. But because our bodies cannot produce these compounds, we must get them in the foods we eat as part of a well-balanced diet.
