Sensitivity notes
Why fructans food checker matters
Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.
- Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
- Green parts of leeks and scallions are lower in fructans
- Sourdough bread may be better tolerated than regular wheat bread

Serving size, prep, and portion notes for wheat
Wheat is the reference food for gluten, but it is also rated highest of the wheat foods for fructans, which is why so many people who feel better off wheat do not actually have a gluten problem. Wheat contains gluten and is a major trigger for celiac disease, and it is separately rated high in fructans (a FODMAP), pro-inflammatory and a common eosinophilic esophagitis (EoE) trigger.
Watch for
Contains gluten and is the primary grain to avoid for celiac disease and wheat allergy / Rated highest in fructans among wheat foods, so it can bloat people who are not gluten sensitive at all / One of the top-six eosinophilic esophagitis (EoE) trigger foods, alongside milk, egg and soy / Rated pro-inflammatory, part of why it is cut on AIP and paleo protocols
