Butter
“The effects of different dietary fats on lipid profiles, metabolic markers and health outcomes may vary not just according to the general classification of their main component fatty acids as saturated or unsaturated but possibly according to different profiles of individual fatty acids, processing methods as well as the foods in which they are consumed or dietary patterns.”
What fat is found in hydrogenated vegetable oils
Trans fats
E.g. crisco
Can be mono or polyunsaturated
