High-fiber diet may promote healthy, disease-free aging

June 25, 2016

(HealthDay)—A diet inclusive of foods rich in fiber may fuel more successful aging, according to research published online June 1 in the Journals of Gerontology.

The researchers tracked 1,609 participants, 49 years and older, for a decade starting in 1994. At the start, all were free of cancer, , and stroke. Successful aging status at follow-up was defined as the absence of disability, depressive symptoms, , respiratory symptoms, and chronic diseases such as cancer and coronary artery disease. Surveys assessed dietary routines, with a specific focus on fiber, carbohydrates, and .

The team found that only 25 percent of were meeting daily fiber intake recommendations, and 15.5 percent of the participants had aged successfully over the 10-year time frame. Those with below-average levels of fiber consumption were least likely to have aged well. The top fiber consumers were found to be 79 percent more likely to remain fully functional and disease-free as they aged.

"Our observations need to be confirmed by other large studies, and we can't make recommendations at this stage such as pushing for a more plant-based diet," lead author Bamini Gopinath, Ph.D., an associate professor at the University of Sydney's Westmead Institute for Medical Research, told HealthDay.
