We know that a balanced diet rich in a variety of foods is best for optimal health. Media reports suggesting links between a particular food and a health benefit can be confusing.
Most studies show correlations between a particular food and a protective effect against disease.
A correlation doe s not necessarily mean a direct effect. Remember, foods contain different amounts of vitamins, minerals and phytochemicals depending on the way the fodds are prepared, stored, and eaten in combinatio with other foods. Consumer Reports on Health, March 1999 issue summarized some of the most common disease fighting foods and their subsequent effects. This has been shown in animals, and there is no supporting evidence of the same effect in humans. Regardless, a daily diet should include an ample supply of vegetables.
