Low FODMAP BBQ: How to Enjoy a Barbecue Without an IBS Flare

Low FODMAP BBQ: How to Enjoy a Barbecue Without an IBS Flare

By Dr. Onikepe Adegbola, MD PhD — Johns Hopkins-trained physician-scientist

Summer BBQs are an IBS minefield: onion-loaded burgers, baked beans, coleslaw with garlic mayo, and desserts full of dairy and fructose. But grilled meat is inherently FODMAP-safe — the problem is everything around it. Here's your game plan.

Key Takeaways

• Plain grilled meat (no marinade or plain salt/pepper) is always FODMAP-safe
• BBQ sauce is almost always high FODMAP (HFCS, garlic, onion)
• Skip the bun if it's a large wheat roll; bring gluten-free buns if you want bread
• Side dishes are the danger zone — coleslaw, baked beans, pasta salad, corn on the cob (in excess)
• Take FODMAP digestive enzymes before eating — your best BBQ defense

BBQ Safe List

• ✅ Plain burger patty (salt, pepper) with lettuce, tomato, pickle
• ✅ Grilled chicken breast
• ✅ Grilled steak
• ✅ Hot dogs (check for garlic — some brands use garlic powder)
• ✅ Corn on the cob (half) — half a cob is low FODMAP
• ✅ Potato salad (if homemade, no onion) — potatoes + mayo + mustard + chives
• ✅ Chips (plain) — potato or corn chips without seasoning
• ✅ Fruit: strawberries, grapes, pineapple, oranges
• ✅ S'mores (1) — marshmallow + chocolate + graham cracker in small amount
• ❌ BBQ sauce — HFCS, garlic, onion. Use low FODMAP seasoning or mustard instead.
• ❌ Baked beans
• ❌ Coleslaw (cabbage in large amounts + garlic mayo)
• ❌ Pasta salad (wheat pasta + dressing with garlic/onion)
• ❌ Watermelon (large servings)

What to Bring

1. FODMAP digestive enzymes
2. Low FODMAP seasonings for your meat
3. GF buns (if you want bread)
4. Your own safe side dish (potato salad without onion, rice salad)
