No oil in my diet....really?

On April 16, 2015 UC Davis's Rosane Davis published an article making the arguement that "When we eat oils, we do immense damage to our cardiovascular health, we decrease our insulin sensitivity, we take in hundreds of empty calories and we damage our immune system. We don’t need them and we should avoid them ALWAYS."
Wow, that seems to be a really tough order. Check out this article and see what you think.
