Dietary flavonoids make fruits and vegetables colorful. The anthocyanidins have lovely red and purple colors. They are found in colorful berries such as cranberries, currants and blueberries.
What Will a Diet with Colorful Berries Do for Your Health?
In a study of stroke risk, more than 16,000 healthy Americans filled out detailed questionnaires about what they ate. (The study is called REGARDS: Reasons for Geographic and Racial Differences in Stroke.) The researchers then calculated how much anthocyanidins and proanthocyanidins the volunteers were eating. They also monitored the participants’ health for approximately six years.
People who ate more of these compounds were less likely to develop heart disease during the study. The researchers had to adjust for the fact that the volunteers who ate more colorful berries were also wealthier, better educated, more likely to exercise and less likely to smoke.

Why not follow either a DASH diet or a Mediterranean diet? The generous quantities of vegetables and fruits in these eating plans may provide enough of these colorful plant chemicals to be helpful.
