Dietary Fiber and Aging

Currently, healthy aging is a major public concern. In between, nutritional interventions and dietary patterns are supposed to play crucial roles in regulation/delaying the aging process. High intake of dietary fiber is inversely associated with reduced risk of several age-related diseases. A bulk of evidence indicated that consumption of dietary fiber is implicated with lower concentrations of inflammatory and oxidative stress markers, resulting in improving health status during aging and extending the life span. Even, it was proven that inadequate amounts of dietary fiber are accelerating the aging process. Significant intake of dietary fiber is an essential parameter of a healthy aging. The current chapter reviews the specific roles of dietary fiber in conjunction with age-associated-gastrointestinal system, age-associated-metabolic status, age-associated cardiovascular diseases, age-associated neurodegenerative diseases, cancer, immune system, and allergic disorders.
