Nutrition profile
- Protein: 15–25 g per cooked cup, with a favourable amino-acid profile though limiting in methionine (complementary with grains).
- Fibre: 10–15 g per cooked cup — meaningful contribution to daily targets.
- Resistant starch and prebiotic fibre: substrate for butyrate production.
- Polyphenols: anthocyanins in dark beans, isoflavones in soy.
Evidence
- PREDIMED and other Mediterranean-diet trials include legumes as a core component.
- Cohort meta-analyses: 3–4 servings/week associated with 8–14% lower CV mortality.
- Blue Zones: Sardinia, Ikaria, Nicoya, Loma Linda cultures all consume legumes as a staple.
Practical
- Preparation: soaking and pressure-cooking reduce phytates and lectins.
- Digestibility: gradually increase intake to allow microbiome adaptation.
- Convenience: canned beans (rinsed) are nutritionally similar to home-cooked.
