16. Digestive Diseases and Nutrition: Questions and Answers

Fiber Content of Foods

I know it’s good to eat a lot of fiber to stay regular, but sometimes I eat too much fiber and have painful gas or even diarrhea. What’s the best way to strike a healthy balance?

If fiber doesn’t protect against colon cancer, why should I continue to eat foods high in fiber? 
Is there any value to altering my diet to protect against colon cancer?

What foods should a person avoid if he or she has heartburn, GERD, or Barrett’s esophagus?

What are some common foods that may contain gluten?

My son has just been diagnosed with celiac disease and needs to follow a gluten-free diet. 
Can you offer some suggestions to help us get started?

How important is nutrition for people with inflammatory bowel disease (IBD)?

What should I do to maintain proper nutrition?

I am concerned that my child, who has been diagnosed with inflammatory bowel disease (IBD), is not getting the nutrition he needs. What’s the relationship between IBD and nutrition in children?

I recently had the pelvic pouch surgery, and diarrhea (up to 15 loose bowel movements 
daily) has become a real problem for me. Can you suggest any dietary changes to help improve this?

Should I be taking a vitamin or mineral supplement if I have a gastrointestinal disease?

I am confused about the diet for diverticulitis . They say more fiber, even fruit with skin, but other information I’ve read states that people with diverticulitis cannot tolerate seeds, skins, raw vegetables, etc. Can you give me direction on exactly what is digestible for people with this condition? Sure hope to get some help, I’m in a panic.
