How Not to Age — Dr. Michael Greger
Evidence-based guide to slowing aging through whole food choices — the food-first answer to the longevity question.
Greger's research directly supports the fibertarian approach: the longevity pathways activated by fiber, polyphenols, and plant foods are the same ones Sinclair targets with supplements.

Lifespan — Dr. David Sinclair
Sinclair's case for treating aging as a disease, with the science behind sirtuins, NAD+, and epigenetic reprogramming.
The complement to Greger: where food gets you most of the way, Sinclair maps the remaining gap and the supplement strategies that address it.

Longevity Supplements
Targeted supplements for what a fiber-first diet can't cover on its own — grounded in Sinclair and Greger research.
NMN (Nicotinamide Mononucleotide)
NAD+ precursor that declines with age — the supplement Sinclair credits most for cellular energy and DNA repair.
The one genuine dietary gap: dietary NMN exists in edamame, broccoli, and avocado but at doses too low to move the needle. This is where supplementation earns its place.

Trans-Resveratrol
Sirtuin activator found in grape skins — Sinclair pairs it with NMN; Greger notes its polyphenol profile tracks with fiber-rich plant diets.
Red grapes and berries contain resveratrol, but at doses far below what research uses. A fat-soluble supplement taken with a meal closes the gap while staying food-adjacent.

Spermidine
Autophagy trigger found naturally in wheat germ, legumes, and aged foods — one of the few longevity compounds fibertarians already get more of than most.
Greger highlights spermidine as a strong whole-food argument: the fiber-first diet is already a spermidine-rich diet. A supplement is optional — but worth knowing about for those not hitting targets through food.

Fisetin
Senolytic flavonoid concentrated in strawberries — clears aged, dysfunctional cells that accumulate with age and drive chronic inflammation.
Strawberries are the richest food source, but therapeutic doses require a concentrate. Greger covers senolytics in 'How Not to Age'; fisetin is the most accessible entry point.

Berberine
Plant-derived AMPK activator — often called 'nature's metformin' and one of the most studied longevity compounds outside of pharmaceuticals.
Here's the fibertarian connection: butyrate from fiber fermentation activates AMPK through the same pathway as berberine. A high-fiber diet gets you there through food; berberine is the direct supplement route for those who want to stack the effect.

Quercetin
Polyphenol senolytic found in onions, capers, and apples — often stacked with fisetin for a complementary senescent cell clearance effect.
Quercetin is abundant in a fibertarian diet, but research doses exceed what food delivers. Greger covers it as part of the broader polyphenol case for plant-heavy eating.

Psyllium Husk
A soluble fiber supplement that feeds butyrate-producing gut bacteria — the same AMPK-activating pathway targeted by berberine.
Bridges the fiber-first diet and longevity supplement categories: food-derived, mechanistically relevant, easy to add.
