Fructan Reintroduction Trial
Fructan reintroduction trial tests wheat, onion, and garlic separately—find gram ceilings for carbs and flavor instead of banning entire grain groups.
A fructan reintroduction trial tests wheat, onion, garlic, and some vegetables separately—fructans are one FODMAP class, not one food. Garlic powder in a sauce may fail where a small wheat portion passes.
Start with a published low dose, hold other high-fructan foods constant, and note whether symptoms are gas, pain, or urgency. Many athletes need some wheat for race carbs; finding a gram ceiling beats banning all grains.
Cooking method matters less than total fructan load for many people.
Common questions
-
Is wheat always high fructan?
Wheat contains fructans, but dose and pairing matter. Some people tolerate a modest pasta portion while failing onion or garlic at smaller weights.
