IBS-C Diet: What to Eat and What to Avoid

The key to managing IBS-C symptoms is by following a healthy and balanced diet. While there is no one-size-fits-all approach, some general guidelines can help alleviate symptoms:

1. Increase Fiber Intake

Fiber is essential in promoting regular bowel movements and preventing constipation. However, not all fiber is created equal. It is important to increase soluble fiber intake while limiting insoluble fiber, as the latter can trigger IBS-C symptoms. Some examples of high soluble fiber foods are:

  • oats
  • barley
  • psyllium husk
  • beans
  • apples
  • pears
  • avocado
  • carrots

On the other hand, some high insoluble fiber foods to avoid or limit include:

  • cabbage
  • brussels sprouts
  • cauliflower
  • corn
  • broccoli
  • beans
  • lentils
  • nuts and seeds

2. Choose Low-FODMAP Foods

FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) are types of carbohydrates that are poorly absorbed in the small intestine and can trigger IBS-C symptoms. A low-FODMAP diet eliminates high FODMAP foods for a few weeks, and then gradually reintroduces them to identify the ones that trigger symptoms. Some examples of low-FODMAP foods include:

  • banana
  • blueberry
  • grapefruit
  • orange
  • potatoes
  • rice
  • chicken
  • tofu

3. Stay Hydrated

Dehydration can worsen constipation and other IBS-C symptoms. Make sure to drink enough water and fluids throughout the day. Aim for at least eight glasses of water per day.

4. Limit Caffeine and Alcohol Intake

Caffeine and alcohol can irritate your gut and worsen IBS-C symptoms. It is recommended to limit your intake of coffee, tea, and alcohol.

5. Eat Smaller and Frequent Meals

Eating large meals can cause bloating and discomfort. Instead, try to eat smaller and more frequent meals throughout the day.

6. Avoid Trigger Foods

Some common trigger foods for IBS-C are spicy foods, fatty foods, and dairy products. Identify your trigger foods and avoid them.

7. Work with a Registered Dietitian

A registered dietitian can help you create a personalized nutrition plan for IBS-C that works best for you. They can also provide support and guidance throughout your journey.
