Food is Medicine
by Sarah Pounders
The latest medical advice mimics recommendations given by Hippocrates thousands of years ago: Let food be your medicine. Mounting research confirms that consuming fruits and vegetables provides health benefits beyond supplying vitamins and minerals. Researchers who study phytonutrients natural health-promoting chemicals found in plants are publishing studies at a rapid rate that indicate a connection between phytonutrients and decreased inflammation, cancer prevention, decreased risk of heart disease, improved memory, and lowered blood sugar levels.
On a scientific level, these phytonutrients work in your body in a number of ways. Scientists dont fully understand all the biochemical mechanisms involved. But what matters most is the consistent, simple message that has emerged: Fruits and vegetables are good for you, so eat more of them!
There is no single miracle phytonutrient to consume for good health. Research reveals a wide variety of these plant chemicals present in various fruits and vegetables. When youre reading a magazine article about them, its easy to get bogged down trying to remember which pigment or compound offers which benefits. Nutrition educators have hit on a handy way to help consumers put this information to practical use: Eat a Rainbow!
Many of the phytonutrients are also pigments that are responsible for the colors of fruits and vegetables, so rather than trying to remember long chemical names, you can just group the fruits and vegetables by color. The chart below, provided by the Vegetable and Fruit Improvement Center at Texas A&M University, lists some examples.
