While people always felt properties of some foods were important to health before the opening decades of the s, it wasn’t until after the turn of the century that these factors were identified and synthesized. In , an Englishmen named William Fletcher became the first scientist to determine whether the removal of special factors, known as vitamins, from food would lead to diseases. Doctor Fletcher made the discovery while researching the causes of the disease Beriberi. Eating unpolished rice, it seemed, prevented Beriberi while eating polished rice did not. Hence, Fletcher suspected that there were special nutrients contained in the husk of the rice removed during the polishing process that played a role. In , English biochemist Sir Frederick Gowland Hopkins also found that certain food factors proteins, carbohydrates, fats, and minerals were important to growth in the human body: his work led to his receiving together with Christiaan Eijkman the Nobel Prize in Physiology or Medicine. Vitamine was later shortened to vitamin. Together, Hopkins and Funk formulated the vitamin hypothesis of deficiency disease, which asserts that a lack of vitamins could make you sick.
