Like broccoli, cauliflower can be a trigger food as well as a particularly gas-inducing food. So it makes sense that your tummy may start to rumble and you may experience gas inflammation after you nibble crudités (i.e., broccoli, cauliflower, cabbage, Brussels sprouts, and raw salad).
Cauliflower can be used to replace rice and potatoes, but this is not a good choice for people with IBS. Instead, try brown rice for a healthy option that is bloat-free. Alternately, you can steamed broccoli or cauliflower so you can still get adequate veggie intake without problematic IBS symptoms.
