When researchers in Boston examined the diets of folks who had survived one heart attack and were at risk for another, they found that eating lots of one food ingredient reduced the risk of dying by 25 percent during the nine years of the study.
The longevity food ingredient is dietary fiber.
And while other studies show that eating more fiber lowers your overall risk of heart disease, this is the first study that shows that even after you have had a first heart attack, eating plenty of fiber-filled fruits and vegetables can help you live longer.
In this research, cereal fiber seemed to be particularly beneficial.
Among Americans, fewer than 5 percent consume the recommended minimum amounts of fiber: 25 grams a day for women and 38 grams a day for men.
Apples, for example, contain more than 4 grams of fiber apiece. A cup of raspberries has 8 grams. A cup of broccoli has about 5 grams. Oatmeal has 4 grams of fiber in a cup.
