And even when vegetable oils aren't being hydrogenated and eaten in margarines, cakes and biscuits etc and are used for frying as a liquid, they degrade into
toxic oxidation products (never mind the glyphosate contamination and genetic engineering prevalent in modern varieties).
Besides the damage from trans fats, vegetable oils such as peanut, corn, and soy oil degrade into highly
toxic oxidation products called cyclic aldehydes when heated, and these byproducts may actually do more harm than trans fat.
