Use oils generously. Curtailing oil is entirely unnecessary, part of the nutritional dietary blunders of the past forty years. Use healthy oils liberally, such as extra-virgin olive oil, coconut oil, avocado oil, and cocoa butter, and avoid polyunsaturated oils such as sunflower, safflower, corn, and vegetable oils (which trigger oxidation and inflammation). Try to minimize heating and cook at lower temperatures; never fry, since deep-frying is the extreme of oxidation that triggers, among other things, AGE formation.
