I understand, Helpme_1992! Extra virgin olive oil and avocado oil tend to be more expensive, but they are significantly healthier than vegetable oils. Olive and avocado oils contain omega-3 fatty acids ("good fats") that help reduce inflammation. Vegetable oils have been shown to cause inflammation because they are higher in omega-6 fatty acids. When we consume too much vegetable oil, we get more omega-6 fatty acids than we need, throwing off the ideal ratio for omega 6:omega 3 (2:1). This is what then supports inflammation in the body.
