Analysis v1
When scientists use a common test to check if oils like rapeseed or grape seed oil have gone bad from heating, the test might miss how bad they really are because it can't see some of the chemicals that form during heating — even though those chemicals are definitely there.

Oxidative Stability and Genotoxic Activity of Vegetable Oils Subjected to Accelerated Oxidation and Cooking Conditions
Cross-Sectional Study
In Vitro
2023 May 29The study shows that heating these oils creates lots of bad compounds, but it doesn’t check whether the common test (TBARs) misses some of them because of how the test works — so we can’t say if the claim about the test being flawed is right or wrong.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
