Lima beans (*Phaseolus lunatus*)—also called butter beans—are large, flat pulses native to Peru but now grown worldwide. When cooked they become creamy, slightly sweet and hold their shape in braises.
- **Complete meal builder**: protein + complex carbs make a filling base.
- **Soluble fiber** helps lower LDL‑cholesterol and supports gut microbiota.
- Natural **resistant starch** feeds beneficial colonic bacteria, producing SCFAs.
- Folate and iron aid red‑blood‑cell production—important for pregnancy & plant‑based diets.
Drawbacks & Precautions
- **Linamarin**, a cyanogenic compound in raw beans, breaks down with boiling—never eat raw or under‑cooked.
- Oligosaccharides may cause gas; soak 8 h, discard water and cook 45 min to reduce.
- Rare favism‑like reaction in G6PD‑deficiency sufferers—consult a doctor if unsure.
Culinary Uses
- Classic **succotash** with corn & peppers.
- Blend with garlic, lemon and olive oil for a silky bean dip.
- Simmer in tomato‑paprika sauce for **Spanish fabada‑style** stew.
- Toss young *baby* limas into salads for nutty bite.
Storage Tips
• **Dried** beans keep up to 24 months in an airtight jar.
• **Cooked** beans refrigerate 3–4 days or freeze 3 months (freeze flat for quick thaw).
Sustainability
As legumes, lima beans fix atmospheric nitrogen, cutting fertiliser needs and improving soil health. Choose organic or Fair‑Trade Peruvian varieties to support smallholders.
