Serving size, prep, and portion notes for canola oil
Canola oil is clean on the food-chemistry triggers people usually worry about: no histamine, no gluten, no lactose, no sulfites and effectively no FODMAPs, since it is pure fat. Where it is graded poorly is as a refined seed oil. It scores pro-inflammatory in our data and does not fit paleo, AIP or a traditional Mediterranean pattern. The honest read is that canola is fine on sensitivity triggers, and if you avoid it, that is a whole-diet and processing choice rather than a reaction risk.
Watch for
Rated pro-inflammatory as a refined, high-omega-6 seed oil, which is the real reason people swap it out, not a histamine or FODMAP reaction / Not paleo, AIP or Mediterranean-diet compliant, so it is excluded on those patterns by definition rather than because it triggers symptoms / Highly refined and industrially processed, the crux of the "seed oil" debate; the counterpoint is that it is low in saturated fat and neutral in flavour, so treat this as a dietary preference, not a proven trigger
