Raffinose Stachyose Legumes
Raffinose and stachyose in legumes are fermentable carbs that cause gas—reduced by soaking, cooking, portion ramps, and optional enzymes.
Raffinose and stachyose in legumes are short-chain carbohydrates humans cannot digest in the small intestine—they pass to the colon where bacteria ferment them, producing gas. Beans, lentils, and chickpeas are rich sources; soaking and discarding water leaches part of them.
Tolerance improves with habitual small servings and diverse fiber.
