As people are looking into a more paleo style diet, there is often a question about whether or not dairy is okay to eat. There are tons of different opinions on this and good arguments on both sides. I'm posting Mark Sisson's (Primal Blueprint) and Whole 9's articles on the subject. Whole 9 is a more traditional paleo stance that says no dairy, where Primal Blueprint says we don't really know and it depends a lot on the individual. BOTH agree that heavy cream, butter and ghee are OKAY because the bad parts (lactose and casein) are not found in these products...they're essentially just fat. (Whole 9's article doesn't say this but you will see Dallas says this in one of the comments below the article).
