I love using coconut oil and prefer it for cooking over pretty much anything else other than butter. I do like butter, but prefer to use Ghee - which I typically just make for myself rather than buying it. I do use grass-fed butter to make Ghee or clarified butter (the dairy solids are removed in the process). I've found that my body does better without dairy. Personally, I use far more saturated fats than I once did and my cholesterol numbers are excellent - far better than when I was on a traditional low-fat diet. I am careful about my fat sources however, which I do think makes a difference in many different ways. I've relegated olive oil to salad dressings, and I use either hazelnut or avocado oil to make mayo.
