3. Avoid High-FODMAP Foods

FODMAP foods are carbohydrates and sugars that the body cannot easily digest. Keep in mind that FODMAP intolerance is not an allergy, but a reaction to certain foods triggered by the good bacteria found in the colon that ferment carbohydrates. Additionally, the condition causes there to be too much water in the large intestine, resulting in diarrhea, bloating, and gas. Early research suggests that some people with diverticulitis may benefit from limiting FODMAP foods. These foods include:

  • Stone fruits such as apples, pears, plums and watermelon
  • Dried fruits
  • Dairy foods with lactose, including milk, ice cream, cottage cheese, and yogurt
  • Garlic
  • Onions
  • Vegetables such as asparagus, celery, cabbage, cauliflower, sweet corn, and artichokes
