Why Onion powder may trigger symptoms
Onion powder is concentrated onion and is usually high FODMAP because the fructans stay in the dried powder. It is one of the most common hidden triggers in seasoning blends and savory packaged foods.
Bloating can happen when poorly absorbed carbohydrates ferment in the gut and create gas. Portion size, speed of eating, stress, and baseline gut sensitivity can all change the reaction.
For IBS-sensitive people, the total meal matters. A food can feel different when it is paired with wheat, dairy, beans, sugar alcohols, large portions, alcohol, or a stressful day.

Chives or scallion greens can be a useful swap. Chives and scallion greens give allium flavor without using the onion bulb.
