Which FODMAPs are in dark rye
Fructose: Excess fructose means the food has more fructose than glucose. That extra fructose is absorbed less efficiently and can draw water into the bowel. Read more about fructose malabsorption.
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.
