Ranked by polyphenols

Cooking oils with the most polyphenols

Total phenolics per 100 g oil by the Folin–Ciocalteu test (mg gallic acid equivalents) — our own sample-weighted mean of retail surveys. Deeper green is more. Unrefined and unspecified-grade oils only for now: refined oils have not had a full search, and animal fats carry no plant polyphenols.
