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
- Spelt and ancient grains still contain fructans despite marketing claims
- Portion size matters - small amounts may be tolerable

What to know about corn oil
Corn oil is fully refined corn fat, so it carries almost none of the protein, fibre or plant compounds that trigger food sensitivities. It is effectively free of gluten, lactose, histamine, salicylates and FODMAPs, which is why pure corn oil rarely causes an acute reaction. The honest caveat is nutritional rather than chemical: corn oil is a high-omega-6 seed oil, in the same camp as canola and sunflower, so a diet built around it leans pro-inflammatory. If you are eating to calm inflammation, it is one to use sparingly instead of as your main cooking fat.
Watch for
- High in omega-6 linoleic acid, so like canola and sunflower oil it tilts pro-inflammatory when it becomes your dominant fat
- Fully refined, so it is not a meaningful source of histamine, salicylate, lectins or FODMAPs and pure corn oil is an unlikely acute trigger
- Common as the frying fat in processed and restaurant food, where the real triggers are usually the batter, breading or seasoning, not the oil itself
