6 Diets for IBS: High-Fiber Diet, Elimination Diet, and More

4. Elimination diet

An elimination diet focuses on avoiding certain foods for an extended period of time to see if your IBS symptoms improve. The International Foundation for Functional Gastrointestinal Disorders (IFFGD) recommends cutting out these four common culprits:

  • coffee
  • chocolate
  • insoluble fiber
  • nuts

However, you should forgo any food you find suspect. Completely eliminate one food from your diet for 12 weeks at a time. Note any differences in your IBS symptoms and move on to the next food on your list.

5. Low-fat diet

Chronic consumption of high-fat foods is a known contributor to a variety of health issues, such as obesity. However, it can be especially hard on those with IBS by worsening symptoms.

High-fat foods are generally low in fiber, which can be problematic for IBS-related constipation. According to the Cleveland Clinic, fatty foods are particularly bad for people with mixed IBS, which is characterized by a combination of constipation and diarrhea. Embarking on a low-fat diet is good for your heart and may improve uncomfortable bowel symptoms.

Instead of eating fried foods and animal fats, focus on lean meats, fruits, vegetables, grains and low-fat dairy products.
