Here is the paleo story about butter, as far as I know: it clearly is not strictly paleo since its origin as a food staple belong to the neolithic. That is why, to a founder of the paleo diet as L. Cordain butter is a non-paleo food. Afterwards some researchers such as K. Harris have claimed that butter is fine, since it is only fat, and the harmful substances of milk are contained in casein (protein) and lactose. Meanwhile Dr. Davis says that butter provokes a strong insulin response http://www.heartscanblog.org/2010/03/butter-and-insulin.html
In the end I am kind of confused: have you found good scientific evidence one way or another about butter? BTW basically the same would apply to heavy cream...
Here was some discussion a while back of the Dr. Davis post:
butter and heavy cream are two of the main staples in my diet. they are both very pure sources of fat and contain a vast array of nutrients. i eat heavy cream (with absolutely ZERO other funny ingredients) with all kinds of foods. a small bowl of blueberries and cream with a few raw pecans thrown in is a favorite. plus i add cream to lots of drinks and recipes. full fat cream is a great way to get satiating calories from a healthy fat source.
any real butter is better than any substitute. but that being said, organic butter made from cows fed on grass pastures is defintiely the best choice for nutrient density.
pasture butter also makes amazing ghee (clarified butter), one of the most stable cooking oils available, right up there with coconut oil.
profile of pasture butter:
contains a vast array of healthy acids: stearic acid, lauric acid, myristic acid, butyric acid, arachidonic acid
mostly saturated fat, making it very stable and protected against oxidation. also provides excellent appetite satiation.
significant source of omega3 that does not need to be converted
significant source of conjugated linoleic acid (CLA), which has a vast array of health benefits, one of which is that it sort of 'instructs' the body to burn fat and retain muscle. It has also been shown to have very positive affects on cardiovascular health.
contains vitamin K2, which has been proven in multiple studies to carry significant health benefits, especially when consumed in concert with other fat soluable vitamins A&D. The Weston A Price Foundation has been trumpeting this for years, with Chris Masterjohn leading the charge. See his article here on vitamin K2. http://www.westonaprice.org/abcs-of-nutrition/175-x-factor-is-vitamin-k2.html
also consider that people have been eating butter for thousands of years. there were cows eating grass thousands of years ago, and they milk them cows, and drank plenty of raw milk, and ate plenty of real butter. it is only since the turn of last century did we foolishly began to question the benefits of this healthy food.
long live real butter from healthy cows!
