Which FODMAPs are in lupin flour
GOS: GOS (galacto-oligosaccharides) are found mainly in legumes. Like fructans, they aren't digested in the small intestine and are fermented by gut bacteria, which can cause gas and bloating. Read more about foods that cause bloating.
Fructan: Fructans are chains of fructose found in wheat, garlic, onion and some vegetables. People can't fully digest them, so they reach the large intestine, where gut bacteria ferment them. Read more about high FODMAP foods to avoid with IBS.
