If you're buying avocado oil (or a product that lists it), be skeptical: a dark glass bottle, a visible harvest date, and skipping the cheapest option reduce — but don't eliminate — the odds you're getting rancid or cut-with-cheaper-oil product.

Stripped of the "scam"/"fraud" framing and the rest of the video, the checkable claim is: a large share of avocado oil on sale is adulterated or rancid. That holds up, and the video actually understates it: Selina Wang's lab at UC Davis found in 2020 that 82% of bottled avocado oils were rancid or cut with other oils, and a 2026 study on processed foods (chips, mayonnaise, dressings labeled "made with avocado oil") found 89% of them adulterated — most often with soybean or canola oil — with no correlation to price paid. This is documented food fraud verified by chemical methods (fatty-acid and sterol fingerprints), not an anecdote. The practical heuristics (dark bottle, harvest date, skip the cheapest) are reasonable but imperfect: the UC Davis study specifically found that paying more didn't protect against fraud.
