Spermidine-Rich Foods for Autophagy

What is Spermidine-Rich Foods for Autophagy?

Spermidine is a natural polyamine that powerfully induces autophagy — the cellular cleanup process that declines with age. A 20-year epidemiological study of 800+ people found that high dietary spermidine intake was associated with approximately 5 years of reduced mortality. Spermidine levels decline with aging, and restoring them through diet activates the same longevity pathways as fasting.

How do you do Spermidine-Rich Foods for Autophagy?

1. 1.Eat wheat germ daily (richest source: 243 mg/kg) — add 2 tablespoons to yogurt, smoothies, or oatmeal each morning
2. 2.Include aged cheese regularly: mature cheddar (199 mg/kg), Parmesan, and Gouda are among the richest sources
3. 3.Eat spermidine-rich foods with every meal: mushrooms, green peas, broccoli, cauliflower, soybeans/tofu, and lentils
4. 4.Combine dietary spermidine with intermittent fasting — spermidine is essential for fasting-mediated autophagy (Nature Cell Biology 2024)
5. 5.Consider supplementation (1-5 mg/day wheat germ extract) if dietary intake is insufficient, especially for those over 60

How long does it take?
