Vegetable oils are toxic
RooshV: 'Seed oils that enter the body cause oxidation themselves, an indirect form of poisoning. Their unsaturated chemical composition allows them to easily react with proteins, organic molecules, and cell membranes to impair biological functioning and cause oxidative stress which leads to inflammation. This causes cellular damage that, over the long term, is suspected in heart disease, obesity, cancer, diabetes, blood clotting, malnourishment, thyroid dysfunction, and immunity defects. It turns out that polyunsaturated fat, which is heralded as heart-healthy, is most dangerous for the heart because of how readily it causes inflammation.
