  • Anti-inflammatory properties

Avocado Oil

Avocado oil is an amazing monounsaturated fatty acid (MUFA) and is one of the top fats you can have while following the ketogenic diet.

Both avocados and avocado oil are one of the top recommended types of MUFAs for ketosis. MUFAs health benefits have been recognized for many years, unlike saturated fats. Recent research has shown just how important they are for cholesterol and insulin resistance. [*].
