  • Dairy Products: Milk, soft cheeses, yogurt

  • Grains: Wheat, rye, barley

  • Sweeteners: Honey, high-fructose corn syrup, agave nectar

  • Legumes: Lentils, chickpeas, kidney beansHealthline

Foods to Enjoy

Incorporating low-FODMAP foods can help alleviate symptoms:

  • Proteins: Eggs, fish, chicken, tofu

  • Vegetables: Spinach, zucchini, bell peppers, carrots

  • Fruits: Bananas, blueberries, strawberries

  • Grains: Rice, oats, quinoa

  • Lactose-Free Dairy: Hard cheeses, lactose-free milk

  • Herbs and Spices: Basil, oregano, turmeric

Tips for Success

  • Meal Planning: Prepare meals ahead of time to avoid last-minute choices that might not align with your dietary needs.

  • Mindful Eating: Eat slowly and chew thoroughly to aid digestion.

  • Stay Hydrated: Drink plenty of water throughout the day.

  • Consult a Professional: Work with a healthcare provider or dietitian to tailor the diet to your specific needs.
