The importance of good nutrition for good health is not exactly news. Over 2,000 years ago Hippocrates advised, “Let thy food be thy medicine, and thy medicine be thy food.” But not until 1757 did Scottish physician James Lind become the first person to demonstrate a direct link between a major illness and a specific nutrient. Using one of the first controlled medical experiments in history, Lind showed that sailors supplied with citrus fruits and sauerkraut were able to avoid the telltale signs of scurvy: bleeding gums, rough skin, muscle weakness, poor wound healing, anemia and death.
