Chapter 3: Nutrition & Diet

Dietary Fiber & Longevity

Does dietary fiber improve longevity?

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. Observational studies show every additional 10 grams of daily fiber lowers mortality risk.

Practical Emphasis

Build meals around fiber-rich foods — beans, oats, leafy greens, berries, and nuts. Track your intake, aiming for 25–35 grams daily.

Action Tip

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