Love to Eat | An nine-year analysis of almost 400,000 Americans between 50 and 71 years of age when the study began makes a powerful connection between a fiber-rich diet and longevity.
People with diabetes, heart diseases and most cancers were excluded at the beginning of the study, as were people who consumed ‘extreme’ amounts of fiber.
Participants’ fiber intake ranged from 12.6 to 29.4 grams per day in men and from 10.8 to 25.8 grams per day in women. Current U.S. dietary guidelines recommended people consume 14 grams of fiber per 1,000 calories consumed per day—or about 28 grams a day for a typical adult diet of 2,000 calories. via WSJ
Men with the highest fiber intakes had a 23% reduction in the risk of dying while women experienced a 10% reduction when compared to those eating the least amount of fiber.
It’s very important to understand that the study looked at the typd of fiber consumed and found that the most significant health benefits for both sexes came from whole grains, as well as beans. The benefit of beans was stronger in women. While there was a benefit from eating vegetables, the benefits couldn’t be directly linked to lifespan.
Fruit fiber — while perhaps beneficial in overall health benefits — couldn’t be linked to mproved longevity.
