So we all know that when polyunsaturated oils like canola and soybean are heated they go from fairly poisonous to super-ultra death oil due to the oxidation of the polyunsaturated fats; that's a given. But then that begs the question that if oils oxidize so easily when heated, wouldn't nuts and seeds that contain huge amounts of polyunsaturated fats also be terribly unhealthy when cooked? That would mean roasted, baked into bread, used in a frying pan, etc. I believe this to be the case because before I went primal I was into the granola-and-nut-soy-munching hippie stuff and had bad acne from all of the insulin and inflammation. Roasted nuts would undoubteably cause harsh and inflammed pimples just the same as heated vegetable oil. Just my anecdotal observations.
So if this is true, aside from the fact that they're eating bread, all of this flaxseed bread that people are buying is ironically undermining their efforts at eating healthier. But then again I suppose that's the case with a lot of CW.
