Why It Matters for Longevity
Green beans are part of the traditional Italian diet used as an example for the ancestral-diet approach to autoimmune disease prevention Component of a vegetable-rich traditional diet associated with low rates of autoimmune and chronic disease. Beans are a vegetable staple used in multiple Longevity Diet dishes including the Molochio recipe pasta e vaianeia and Ligurian minestrone, served at ~150 g per serving High fiber and plant protein content; low glycemic index; supports gut microbiome diversity and satiety. PMID 31728499: Higher legume intake is associated with reduced all-cause mortality and cardiovascular mortality across multiple cohort studies; beans are among the most studied longevity-associated foods (PubMed) PMID 26853923: Legume consumption is associated with lower fasting blood glucose and improved insulin sensitivity; supports metabolic health as a longevity pathway (PubMed)
How to Use It
Pairs well with olive oil, garlic, tomatoes. Use as a legume in your daily meals according to the Longevity Diet guidelines.

Synergies
- Olive Oil (synergy): Olive oil enhances absorption of fat-soluble vitamin K in beans and contributes anti-inflammatory polyphenols - Pasta (complement): Classic longevity combination in pasta e vaianeia; legume fiber lowers the glycemic response of pasta - Garlic (synergy): Garlic's organosulfur compounds and beans' fiber act synergistically on gut microbiome diversity and immune modulation
Flavor Profile
Taste: mildly sweet, grassy, vegetal, slightly earthy. Aroma: fresh, green, herbaceous. Texture: crisp when raw, tender when cooked, slightly firm. Category: vegetable legume.

Key Nutrients
| Nutrient | Per 100g | Notes |
|---|---|---|
| Dietary fiber | 2.7 g | Mix of soluble and insoluble fiber; supports gut microbiome and bile acid recycling |
| Vitamin C | 12 mg (cooked) | Water-soluble; brief cooking preserves more than prolonged boiling |
| Vitamin K1 | 43 mcg (cooked) | Fat-soluble; absorption enhanced by co-ingestion with olive oil |
| Folate | 37 mcg (cooked) | Essential for DNA methylation; bioavailability ~85% from cooked vegetables |
| Manganese | 0.21 mg (cooked) | Cofactor for SOD2 antioxidant enzyme; plant sources have moderate bioavailability |
