What is a low-fiber diet?
A low-fiber diet contains foods that don't create much waste (stool). This diet slows down your bowels and gives them a chance to rest.
Fiber is the part of plants that your body can't digest. It gives bulk to your diet and helps you feel full. It also helps you have regular bowel movements.
But a low-fiber diet is often needed after bowel surgery or when you have a flare-up of a bowel problem. You might be asked to follow this diet if you have Crohn's disease, ulcerative colitis, diverticulitis, or another condition that can cause swelling, pain, or narrowing of your bowels.
In some cases, you may start with a liquid diet (no solid food) and then add low-fiber foods.
Depending on your health problem, you may eat low-fiber foods for just a short time. Or you may need to follow this diet for the rest of your life.
You may need to take extra vitamins and minerals while you're on this diet. Your doctor will let you know if you need these supplements.
What foods are okay to eat on a low-fiber diet?
You can eat most types of food on a low-fiber diet, including meats, white breads, and many fruits and vegetables. Your doctor can tell you how much fiber you can eat each day.
