Sensitivity notes
Why lectin food checker matters
Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.
- Proper cooking destroys most lectins - never eat raw beans
- Pressure cooking is highly effective at reducing lectins
- Peeling and deseeding reduces lectin content
- Fermentation can reduce lectins in some foods
- Sprouting may increase or decrease lectins depending on the food

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
