Large Umbrella Review Links Higher Dietary Fiber Intake to Lower Risk of Chronic Disease and Mortality
A new umbrella review published in Clinical Nutrition examined the relationship between dietary fiber intake and chronic disease risk across more than 17 million individuals. The review analyzed evidence from 33 meta-analyses covering 38 different health outcomes.
The findings showed that higher dietary fiber intake was associated with lower risk for many chronic diseases. Researchers reported significant inverse associations for 29 health outcomes, including cardiovascular disease, pancreatic cancer, diverticular disease, and all-cause mortality.
The strongest evidence was identified for reduced risk of cardiovascular disease mortality, pancreatic cancer, and diverticular disease. The review also found highly suggestive evidence linking higher fiber intake with lower risk of coronary heart disease, ovarian cancer, and overall mortality.
The authors note that dietary fiber may help support health through multiple protective mechanisms. Despite these benefits, fiber intake remains below recommended levels in many populations worldwide.
The paper concludes that public health strategies should continue encouraging fiber-rich dietary patterns. Researchers also call for additional studies examining the role of specific fiber types in disease prevention and long-term health outcomes.
