INSIGHT

Focus On Nutrient Quality Not Labels

Quality matters more than diet labels; focus on missing nutrients rather than strict frameworks.
Will Bulsiewicz calls fiber, polyphenols, healthy fats, and fermented foods the four workhorses to target.

INSIGHT

Fiber As The Longevity Nutrient

Fiber is described as the longevity nutrient because it feeds the microbiome and produces short chain fatty acids.
These SCFAs (acetate, propionate, butyrate) are highly anti-inflammatory and healing.

ADVICE

Eat Fiber To Produce Healing SCFAs

Increase fiber to boost short chain fatty acids which repair the gut barrier and modulate the immune system.
Prioritize foods that feed microbes so they can produce butyrate, propionate, and acetate.
