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 buckwheat
Buckwheat is naturally gluten-free, so it gets used as a wheat swap, but it carries its own triggers that have nothing to do with gluten. It is high in oxalates, high in nickel and high in lectins. That means it can still cause trouble for anyone managing kidney-stone risk, systemic nickel allergy or lectin sensitivity, so gluten-free does not make it a clean grain across the board.
Watch for
High in oxalates, worth limiting if you are prone to calcium-oxalate kidney stones / High in nickel, one of the higher-nickel pseudo-grains for anyone on a low-nickel diet / High in lectins, so it may not suit a strict low-lectin plan even though it contains no gluten / A recognised food allergen in its own right, separate from wheat: buckwheat allergy can be serious
