Barley Flour and the low FODMAP diet
Barley flour is ground from whole barley grains and retains significant concentrations of beta-glucans and fructans. These complex carbohydrates are highly resistant to small intestine digestion and rapidly reach the colon. Bacterial fermentation produces gas and osmotic water shifts that directly trigger IBS symptoms. Even small servings can accumulate quickly when combined with other wheat-based ingredients.

What can change the result?
Barley flour must be avoided during strict low-FODMAP elimination due to its concentrated fructan profile. Substitute it with certified gluten-free alternatives like rice flour or sorghum flour for safe texture. Barley often hides in pancake mixes, bread flour blends, and commercial baking powders. Always read labels carefully and opt for explicitly FODMAP-tested grain alternatives in your kitchen.
