Reader's Digest Logo By Denise Mann, MS of Reader's Digest | Slide 1 of 5: In a <a href="http://www.bmj.com/content/352/bmj.i17">BMJ study</a> of more than 100,000 men and women, researchers discovered that subclasses of powerful antioxidants called flavonoids—namely flavonols, flavan-3-ols, anthocyanins, and flavonoid polymers—found in select fruits and vegetables may prevent weight gain. The fruits with the greatest effect on weight maintenance were chock full of flavonoids called anthocyanins, and blueberries top this list.About one-quarter cup of blueberries contains 10 milligrams of anthocyanins, and each 10 mg increase is linked with a quarter-pound less weight gain over four years, the BMJ study found. This may seem insignificant, but it can add up with time, the study authors point out. Exactly how flavonoids deter weight gain is not fully understood but eating foods rich in flavonoids—namely produce—may allow us to feel full sooner, and avoid other less-healthy foods that may lead to weight gain.'I am a blueberry fan for many reasons,' says <a href="https://www.northwell.edu/find-care/find-a-doctor/internal-medicine/dr-keri-l-peterson-md-11356864">Keri Peterson</a>, MD, an internist at Lenox Hill Hospital in New York City.
