Does Cauliflower cause gas?
Cauliflower may cause gas for some people with IBS because it is high FODMAP and can deliver mannitol. The reaction is usually dose-dependent, but sensitive people may notice symptoms even from small amounts.
Quick answer

Why Cauliflower may trigger symptoms
Cauliflower is packed with mannitol, a polyol sugar alcohol that ferments hard in IBS guts.
Gas can build when fermentable carbohydrates reach the large intestine and gut bacteria break them down. The same food may feel fine one day and harder during a sensitive week.
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.
