Flavonoids Provide Protection

As reported in the European Journal of Clinical Nutrition, people who consumed the highest amount of flavonoids (compounds found in plant  foods) had a 20 percent reduction in heart disease risk. The meta- analysis, including more than 100,000 people, looked at seven  previously published studies and found that flavonoids, particularly the kinds found in black tea, onions, apples, and broccoli, provided significant protection against the disease.
