A low-fiber diet focuses on foods that are easily digested by the body. This approach restricts the intake of fiber, which is the indigestible part of fruits, vegetables, and grains. This diet is often recommended in specific situations to ease digestion and reduce bowel movements.
Understanding the Low-Fiber Diet
The primary goal of a low-fiber diet is to select foods that are gentle on your digestive system. This typically includes items like plain white bread, white rice, crackers, well-cooked vegetables, and fruits without skin or seeds. Eating these foods helps slow down bowel movements.
It's crucial to avoid high-fiber foods such as beans, whole grains, raw vegetables, berries, nuts, and seeds, as these can be difficult to digest and may exacerbate certain conditions.
What is Fiber?
Fiber is the portion of plant-based foods that your body cannot digest. It adds bulk and form to stool. When you are on a low-fiber diet, you will eat foods that do not have much fiber and are easy to digest.

- Individual Tolerance: The ability to digest food varies from person to person. A healthcare professional may recommend a diet that is more or less limited depending on the reasons it is being used.
- Lactose Intolerance: If you are lactose intolerant, drinking milk products from cows or goats may make diarrhea worse. Take extra care when choosing dairy products.
