While it is well known that a diet with adequate fiber assists in keeping people “regular,” eating the right amount of fiber also helps to avoid disease and disability into old age. Increased dietary fiber may also reduce the risk of developing type-2 diabetes and has been shown to lower blood pressure.

Fiber made the greatest difference in “successful aging.”
