What is so destructive to the human body that Dave would rather smoke a cigarette than eat? Vegetable oil. This kitchen staple found in almost every single home in the United States is slowly destroying the bodies of the American people on the cellular level. On this episode of Bulletproof Dave welcomes Los Angeles Lakers nutritionist Dr. Cate Shanahan onto the podcast to talk about the benefits of healthy animal-based fats and the destructive effects unleashed on the human body from their toxic cousins, vegetable oils. Effects such as cellular degradation and mutation, destruction of the elasticity of skin, brain trauma, and even cellulite.
