Butter vs. Ghee
Ghee is clarified butter, and since butter is Paleo, there’s no reason ghee can’t join the party, too. Because ghee has had the milk proteins removed, many people who can’t tolerate dairy have no problem with ghee.
The Fat Profile
This is good news because butter (and ghee) are loaded with healthy saturated fat and monounsaturated fat. They contain only small a amount of polyunsaturated fat, which we like because saturated and monounsaturated fats are much more stable than polyunsaturated fats. Polyunsaturated fats tend to oxidize when exposed to heat and light, and consuming oxidized fat leads to oxidized cholesterol in our blood. We want to avoid this because it’s the oxidized cholesterol that will latch onto the inside of our arteries, causing inflammation and plaque build-up.
