We all know that loading up on fruits and vegetables can help stave off the extra pounds that come with getting older. Now we know exactly which produce to eat for a trimmer waistline, thanks to a study published in BMJ.
Researchers from Harvard looked at the data from over 124,000 adults over a span of 24 years. Those who gained the least amount of weight over time ate fruits and veggies that were richest with certain types of flavonoids, the chemicals responsible for a fruit or vegetable's bright color.
Those flavonoids were: anthocyanins, found in deep purple and red produce like strawberries, blueberries, and peppers; flavonols, found in onions, broccoli, and berries; and flavonoid polymers, found in apples.
Even though the number of pounds these produce-eaters avoided gaining over the years was less about a quarter-pound every four years, researchers say a little goes a long way in terms of avoiding high blood pressure, diabetes, and heart disease. And it doesn't take much to add the benefits into your diet: a half-cup of blueberries per day should do it, for instance.
