Is it true that peanut butter and bananas can cause constipation in people with IBS?
Asked by anonymous on Apr 22, 2008 in Health Conditions

I have truly had IBS for the last 2 years, but was not diagnosed until a few months ago. It seems like it is just getting worse despite the fact that I get enough fiber and eat fairly heatlhy and avoid many trigger foods. I was told recently that peanut butter and bananas can cause constipation. I eat a banana w/ peanut butter everyday, and so is it true?


Peanut butter and bananas do not cause constipation. They are both moderately high fiber foods that actually prevent constipation. A high-fiber diet can reduce the symptoms of IBS for many people. Count your grams of fiber to reach 30 grams a day, and watch out for high fat foods and caffeine because they are common dietary triggers for IBS. IBS is also triggered by stress, and so meditation or yoga might help. Read more about Irritable Bowel Syndrome from the Guide to Heartburn and GERD at
