More than a millennium ago, Hippocrates wrote: "Let your food be your medicine, and your medicine your food." Today diet and nutrition are aspects of healthcare that deserve more attention.

When a person becomes ill, nutrition can often be as helpful as drugs in contributing to restored health. Drugs are mostly synthetic and are designed to treat disease symptoms and interfere with biological systems after the body's natural defenses have failed. Food, on the other hand, provides natural raw materials the body uses to perform the functions of health maintenance and restoration.

This section is designed to remind us that nutrition and nutritional supplementation can affect health in vitally important ways.
