A lot is misunderstood about cholesterol. Mostly outright lies by Big Pharma to physicians who don't have time to read research and study papers. My doc hasn't known what to do with me for refusing ststins. Been there, done that and statin side effects of fibromylagia, diabetes and weight gain are by far worse than the false fear of heart attacks.

I think back in the late '70s Consumer Reports came out with a book called The Medicine Show. There was a lot of interesting information in it but, one thing that stuck with me is the details of a cholesterol study. It was a typical group that ate a low cholesterol diet against a control group that didn't study. The study found that the low cholesterol group had less heart attacks but, the control group lived longer. So, if your goal is less heart attacks at the expense of all else, then a low cholesterol diet makes sense. However, I think most of us would prefer to live longer than to die earlier of something besides a heart attack.
I've also wondered about some other things that seems unrelated but, might be correlated. Since we've gone to low fat diets, seems to be a lot more depression, autism, and autoimmune disorders. I have nothing concrete to link those with low fat diets but, there could be a link. No one seems to be looking to see whether there is.
