What It Is
Cod liver oil is exactly what it sounds like: oil derived from the liver of the cod fish. Since cod (being fish) is Paleo-friendly, and a good dose of liver is about as healthy as it gets, there’s no reason we can’t include cod liver oil as part of a Paleo lifestyle.
The Fat Profile
Actually, there are a number of reasons to include it in your diet. Like all fish oil, cod liver oil is an excellent source of omega-3 fatty acids. This is a type of polyunsaturated fat that we like because it is anti-inflammatory and imparts several health benefits. If you’re not already eating fish on a regular basis, you should make it a point to supplement with fish oil.
The Health Benefits
Cod liver oil in particular is extremely high in vitamins A and D. These nutrients are essential for healthy eyes, skin, bones, and teeth. Let’s just say they’re necessary for healthy bodies.
Mark Sisson gave cod liver oil his Primal seal of approval.
