In 1747, Joseph Lind demonstrated that giving citrus fruit to sailors on long voyages cured them of scurvy, a debilitating illness. Scurvy was the first disease for which the proven cause was a nutritional deficiency, although the missing nutrient, vitamin C (ascorbic acid), was not isolated until 1928.1 In 1912, Casmir Funk proposed that inadequate consumption of “vital amines” (vitamins) in food could cause disease.1 He had isolated vitamin B1 (thiamine), the nutrient that, when deficient in the diet, will result in beriberi. Based on a growing recognition of diseases caused by insufficient vitamins in the diet, the US government began to require fortification of commonly consumed foods.2,3 Examples include milk fortification with vitamin D and flour enriched with thiamine, folate, riboflavin, and niacin.2 The goal of fortification is to prevent diseases of vitamin deficiency.
