How could a person with diverticulosis eat fiber if the fiber gives you gas?

Fiber in excess: Can cause gas. Add fiber slowly to the diet rather than make abrupt changes. Also inadequate fluid or excessive caffeine or alcohol can cause the fiber to produce excess gas. It can be done but it does require changing your eating and drinking habits.

Little at a time.: Try to have a little bit of fiber at a time, divided amongst several meals in a day. Your body might tolerate it better that way. For women, 35 grams daily and 50 grams daily for men - divide it up amongst five meals daily.
