Broccoli vs Cauliflower: Which Is Worse for IBS?
Both broccoli and cauliflower are cruciferous vegetables that can trigger IBS symptoms. Broccoli is moderate-FODMAP (safe in small servings up to 3/4 cup), while cauliflower is high-FODMAP due to mannitol content. Broccoli is the better choice.
Up to 3/4 cup (75g) per sitting
Up to 1/2 cup (65g) per sitting
The Verdict
Broccoli is safer in small portions (3/4 cup). Cauliflower is high-FODMAP and harder to tolerate. For rice alternatives, use potato instead of cauliflower rice.
Detailed Breakdown
It depends on the portion size. Broccoli is low-FODMAP in small servings (about 3/4 cup or 75g of heads) and generally tolerated by most people with IBS at that amount. However, larger portions become moderate to high in fructans and sorbitol, which can trigger bloating and gas.
Broccoli contains both fructans and sorbitol. At smaller servings these FODMAPs stay below the threshold, but they accumulate quickly as portions increase.

However, larger portions become moderate to high in mannitol and sorbitol, which can trigger bloating, gas, and abdominal discomfort.
Cauliflower contains two polyols — mannitol and sorbitol. Small portions keep these under the FODMAP threshold, but the popular trend of cauliflower rice and pizza crusts often uses excessive amounts.
