Consuming monounsaturated fat is good for you. Consuming polyunsaturated fat, with the exception of omega-3, is not. My understanding is that the polyunsaturated fat in virtually all vegetable oils are omega-6 fatty acids, which we consume way too much of relative to omega-3 fatty acids (which are also technically polyunsaturated but which are not present in any significant quantity in such cooking oils), and the huge quantities of omega-6 that almost everyone consumes is believed to increase our risk of numerous diseases, including cancer. Monounsaturated fat, the primary beneficial constituent of so-called Mediterranean diets, and especially the specific monounsaturated fat called oleic acid, is protective against cancer, reduces LDL (bad cholesterol), and possibly raises HDL (good cholesterol).
