- TCM use: Valued for cooling properties—not proven cancer prevention.
Spinach
- Nutrients: Rich in iron, folate, vitamin K, and lutein (for eyes).
- Caveat: Iron is non-heme (plant-based)—poorly absorbed without vitamin C.
- Science: Supports general health—but no evidence it prevents cancer or extends lifespan alone.
📊 Longevity research: Blue Zones (regions with many centenarians) emphasize beans, whole grains, and leafy greens—but social connection, purpose, and movement matter more than any single food.
