High Fiber intake reduces death risk by 23 percent.
A scientific analysis of a nine year study conducted by the National Institutes of Health and AARP has found a meaningful link between high fiber intake and longevity.
The analysis studied the results of over 400,000 people over fifty. The participants between 50 and 71 years old had fiber intake that ranged from 12.6 to 29.4 grams per day in men and from 10.8 to 25.8 grams per day in women.
The average dietary fiber for most Americans is about 12 grams a day, current US dietary guidelines recommend 28 grams for the average person eating a 2,000 calorie a day diet. This would suggest that the people in this study of people over 50 with the highest fiber intake are simply in line with the recommendations. The study excluded people with extremely high fiber intake.
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 important to point out that the greatest benefits came from particular sources of fiber, whole grains and beans. While vegetable fiber had a small impact on longevity fruits showed no effect at all.
Fiber is a Natural Anti-Inflammatory
Most researchers believe that the anti-inflammatory effects of eating more fiber is possibly part of the reason for lower numbers in cardiovascular, respiratory, and infectious disease death.
