FODMAP foods – What they are and why they matter

When talking about FODMAP foods, foods high in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols that can trigger digestive symptoms. Also known as high FODMAP items, they are the main focus of many gut‑health plans.

Many people turn to the low FODMAP diet, a structured eating plan that limits high‑FODMAP foods to reduce gut discomfort to calm their gut. The diet works especially well for those diagnosed with irritable bowel syndrome, a chronic functional bowel disorder characterized by pain, bloating, and irregular bowel habits. In simple terms, FODMAP foods encompass fermentable sugars that ferment in the colon, producing gas and drawing water into the intestine. By cutting down on these sugars, the low FODMAP diet can significantly lessen IBS symptoms, improve stool consistency, and reduce daily bloating.

High‑FODMAP items fall into five groups. Fructans, found in wheat, onions, and garlic, are the most common offenders; they ferment quickly and often spark the strongest reactions. Lactose, the sugar in milk and soft cheeses, can cause trouble for anyone with reduced lactase activity. Galactooligosaccharides (GOS) appear in legumes and certain beans, while polyols such as sorbitol and mannitol hide in stone fruits, sweeteners, and some artificial gums. Understanding which category a food belongs to helps you swap it for a low‑FODMAP alternative—like replacing wheat bread with sourdough made from spelt or choosing lactose‑free dairy options.
