Dietary Fiber & Longevity

Does dietary fiber improve longevity?

Yes. High fiber intake is consistently linked with reduced risk of cardiovascular disease, cancer, and premature death.

Explanation

Fiber supports health by modulating glucose absorption, lowering cholesterol, promoting satiety, and feeding gut microbes that produce short-chain fatty acids like butyrate, which reduce inflammation and improve gut barrier function. Observational studies show every additional 10 grams of daily fiber lowers mortality risk.

A diverse fiber intake from legumes, fruits, vegetables, and whole grains provides multiple health benefits, from lowering colorectal cancer risk to improving cardiovascular outcomes. The microbiome benefits are especially important for immune regulation and metabolic health.

Practical Emphasis: Build meals around fiber-rich foods — beans, oats, leafy greens, berries, and nuts. Track your intake, aiming for 25–35 grams daily, adjusting gradually to avoid GI discomfort.

Takeaway (Action Tip)

Target 25–35 grams of fiber daily from a variety of whole-food sources.
