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 tomato sauce
Tomato sauce is one of the most concentrated food triggers in an ordinary kitchen. Simmering and reducing tomatoes stacks histamine, salicylates, oxalate, free glutamate and nightshade compounds into every spoonful. It grades high in histamine, so it is a frequent reason people flush, get a headache or a runny nose during an Italian meal, and it is also high in oxalate and a nightshade.
Watch for
High in histamine, and reducing tomatoes down to a sauce pushes it higher, so marinara often bothers people more than a fresh raw tomato does / High in salicylates and a moderate histamine liberator, a double hit if you are aspirin-sensitive or histamine-intolerant / High in oxalate, which matters on a kidney-stone (calcium oxalate) diet / A nightshade with high free glutamate, so it can flare both nightshade sensitivity and umami/glutamate reactions
