I think the sherdog community was on top of these issue long before mainstream coverage but the parts that were really interesting to me where when it mentions that the ones who substituted butter with vegetable oils suffered higher incidences of cancer, gallstones, violent deaths and suicide! It's crazy that that those heated vegetable oils are much more dangerous than, say, butter or cocunut oil oil but out own FDA guidelines is what made restaurants switch to using those deadly vegetable oils in their deep fryers.
