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 seitan
Seitan is pure wheat gluten, the stretchy protein washed out of wheat flour, which makes it the single most concentrated source of gluten you can eat and an absolute no for anyone with celiac disease or a wheat allergy. Sold as vegan wheat meat, it is otherwise a clean, high-protein food on most triggers, but on gluten it is completely off the chart. Store-bought seitan is also usually marinated in soy sauce and vinegar, which layers histamine on top.
Watch for
Pure vital wheat gluten, so it is the most concentrated gluten food there is and strictly off-limits for celiac disease or wheat allergy / Not compatible with an EoE elimination diet, since wheat is one of the core foods that has to come out / Can prompt histamine or mast-cell reactions in sensitive people, and marinated seitan adds histamine from soy sauce and vinegar / High in lectins and hard on SIBO, so a reactive gut may struggle with it even setting the gluten aside
