Does Bell Pepper Trigger IBS?
No. Bell peppers (capsicum) are considered low-FODMAP and are generally safe for people with IBS in standard serving sizes. All colors — red, green, yellow, and orange — are well tolerated. Most people can enjoy them freely without experiencing bloating, gas, or other digestive symptoms.
What Makes Bell Pepper Safe for IBS
All colors of bell pepper — green, red, yellow, orange — are FODMAP-free. They add flavor, vitamins, and crunch to dishes without triggering IBS symptoms.
How it works
Bell peppers contain minimal fermentable carbohydrates. Their natural sugars are well-absorbed in the small intestine and do not cause colonic fermentation.
Common Symptoms
Bell peppers are very unlikely to cause IBS symptoms. If raw peppers cause discomfort, it may be due to their fiber content rather than FODMAPs. Try them cooked instead.

Practical Tip

No. Zucchini (courgette) is considered low-FODMAP and is generally safe for people with IBS when eaten in moderate portions (up to about 65g per sitting).

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.
