High-phenolic olive oil

Good for oxidation markers; early for inflammation.

Olea True sells organic high-phenolic Greek olive oil to “fight inflammation, naturally”. Short answer: across 26 trials, olive oil rich in polyphenols lowered oxidized LDL and an oxidative-stress marker compared with ordinary olive oil. Effects on inflammation markers appeared only in some subgroups and single studies, so that part is early evidence. We found no study of Olea True.
