The evidence, graded
expert consensusUS safety reviewers (2019) judged all but one oat ingredient they reviewed safe in products made not to cause allergy, oat kernel flour and oat sprout oil (not in use then) among them. Oat kernel flour is ground oat kernels, used to scrub, absorb or add bulk; products with 1% caused no allergy in repeat patch tests on 51 and 56 people. Oat sprout oil is mostly linoleic, oleic and palmitic acids and didn’t cause allergy in a mouse test. Oats aren’t a major food allergen, the reviewers noted.Becker 2019 · International Journal of Toxicology ↗
