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 mustard greens
Mustard greens are one of the cleaner cooking greens once you look at the trigger columns: low FODMAP, low histamine, no free glutamate, nothing on the gluten or nightshade side. The peppery bite comes from glucosinolates, which are a flavour chemistry story rather than a graded sensitivity. The only marks against the leaf are borderline ones, moderate salicylate, moderate oxalate and moderate nickel, and boiling and draining pulls all three down. Most people who feel bad after a plate of mustard greens are reacting to what the greens were cooked with rather than the greens: the smoked ham hock in the Southern version, or the ghee, cream and paneer that finish sarson ka saag.
Watch for
Borderline salicylate, so they are fine day to day but you would still count them during a strict elimination phase rather than treat them as a free food / Borderline oxalate. Boiling and discarding the water strips a good share of it, which is how both the Southern and the Punjabi traditions cook them anyway / Borderline nickel, relevant if you have systemic nickel allergy, since brassica leaves draw nickel up from the soil / The classic Southern pot simmers them with smoked or cured pork, which brings histamine, tyramine and nitrites that the leaf itself has none of / Sarson ka saag is normally finished with ghee, butter or cream, so a dairy reaction can be mistaken for a greens reaction
