Garlic and IBS: Why a Tiny Amount Can Cause Big Symptoms
Garlic is one of the most common IBS triggers because it is rich in fructans, a FODMAP group that ferments quickly in sensitive guts. Even small amounts in sauces or seasonings can cause bloating, gas, and cramping for many people.
What to Know Before Testing
- Cooked garlic is still high in fructans for most people with IBS sensitivity
- Garlic powder and garlic salt can be concentrated trigger sources
- Garlic-infused oil (with solids removed) is often easier because fructans do not dissolve well in oil
How to Test
Start with a 2-3 week garlic elimination, then reintroduce a very small measured amount in a plain meal. Track symptoms across 24-72 hours before increasing dose. Test infused oil separately from whole garlic.
FAQ
