I found this post immensely helpful in describing the science behind the health effects of seed oils. But it remains to be said that saturated fat doesn't seem like the best thing for you either. I use the mostly unsaturated oil olive oil nowadays.
It wasn't too bad before in my opinion but this year there was a big drought in the Mediterranean and now it's extremely expensive. Even butter is cheaper than olive oil now I'm afraid... I just try to use less of it. Speaking of butter there are
now a few big studies out there showing that milk fat is not as bad as the saturated fats found in meat. But they are all funded by dairy companies so I don't know if I can really trust them. It's hard navigating the world of fats and health. Fats are good for you but it's hard to know which ones are the good ones.
We make our own olive oil here in Australia, and it's pretty cheap by the can. I decant it into snaller bottles to use. Butter and ghee is thought to be better than most fats, yes. But (unburned) animal fat is still not a terrible thing. It's artificial sweeteners and even plain sugar that seem far more dangerous to me.
