Surprise! Seed oils are bad for you. Oils used in nearly all restaurants for frying are either, sunflower, safflower, or canola oil and all of which are highly processed and contain linoleic acid(Omega 6 fatty acid). much more oxidized and often rancid from production but is scrummed and fragrances are added during the processing to mask the oxidation. I really never understood why there is a large movement lately attempting to defend the use of seed oils as some kind of scientific zealotry that they are not bad for you.
