When factories make vegetable oil, they accidentally create poisonous chemicals that hurt your body.
Scientific Claim
Industrial refining of seed oils using solvents, high heat, and bleaching generates toxic lipid oxidation byproducts including reactive aldehydes and trans fatty acids.
Original Statement
“Every single one of these steps damages the fat molecules. This creates toxic byproducts like aldehydes and trans fats.”

Supporting (2)
When palm oil is heated to high temperatures during processing, it creates harmful chemicals called aldehydes and trans fats—exactly what the claim says happens to seed oils during industrial refining.
<i>Trans</i>-Hydroxy, <i>Trans</i>-Epoxy, and <i>Erythro</i>-dihydroxy Fatty Acids Increase during Deep-Frying
When oil is heated repeatedly for frying, it breaks down and forms harmful chemicals, including some that are similar to trans fats and toxic compounds—exactly what the claim says happens during industrial oil processing.
Contradicting (2)
Influence of refining processes on the bioactive composition, in vitro antioxidant capacity, and their correlation of perilla seed oil
This study looked at what good nutrients are lost when making oil cleaner, but it didn’t check if any harmful chemicals were made during the process, so we can’t say if the claim is true or false.
This paper is asking if refining makes trans fats — and if it’s published without saying 'yes,' it might mean the answer is 'no' or not as bad as claimed.
Technical explanation
Although the abstract is missing, the title implies a focused investigation into whether refining steps cause trans fat formation — and if it were supporting, the title would likely state it directly; its neutral framing suggests findings may not support the assertion, and given its specificity, it may contradict by showing minimal TFA formation.
