Medical Research: What is the background for this study? What are the main findings?
Response: Most weight loss studies have focused on one type of flavonoid, the flavan-3-ols found in green tea, and are limited to small numbers of overweight and obese study participants. We examined 7 subclasses of flavonoids and weight change in 124,086 healthy adults who reported their diet and weight repeatedly over up to 24 years.
Medical Research: What should clinicians and patients take away from your report?
Response: Increased consumption of most classes of flavonoids was associated with less weight gain over four year time intervals, particularly anthocyanins (found in berries and dark red fruits), flavonoid polymers (found in tea), and flavonols (found in onions, tea, and apples). Although increased flavonoid intake was associated with small changes in weight, preventing even small amounts of weight gain could have an important public health impact.
