12. Olive Oil
Like coconut oil, olive oil is keto-friendly. It is a pure fat source that has zero carbohydrates. The ingredient is best used for low-heat cooking or adding to foods that are already cooked because it is not as stable as a saturated fat at higher temperatures. Nevertheless, olive oil has a high content of oleic acid, a monounsaturated fat that can help reduce the chance of heart disease. Extra-virgin oil olive is also packed with antioxidants called phenols that improve artery function and decrease inflammation.
