This was a feeding study that compared the effects of three diets on cardiovascular disease markers: Average American Diet (AAD), American Heart Association Step II diet, and 3 high monounsaturated (MUFA) diets (olive oil, peanut oil, and peanut butter).
The high MUFA diets lowered cholesterol by 10% and LDL by 14%. In addition, the high peanut oil and peanut butter diets lowered cardiovascular disease risk by 16% and 21%, respectively.
