What foods most often trigger IBS?
The foods that most often trigger IBS are fermentable carbs called FODMAPs. These include onion, garlic, wheat in quantity, beans, certain fruits like apples and mangoes, milk in the lactose-sensitive, and sugar-free sweeteners.
Everyone's list differs, which is why a short structured elimination with reintroduction, ideally guided by a dietitian, beats permanent random restriction. Long strict low-FODMAP eating is not meant to be forever.
Stress and irregular meals trigger flares as surely as any food; the gut and the calendar are connected.
