U.S. dietary guidelines tend to recommend low- and no-fat dairy options, yet research suggests that the saturated fat in dairy may not pose as many health risks as originally thought. In this study, 66 people with metabolic syndrome (a risky combination of high blood pressure, high blood sugar, high cholesterol, and/or excess fat around the waist) were assigned to either 3.3 servings of low-fat dairy (milk, yogurt, cheese) per day, 3.3 servings of full-fat dairy (milk, yogurt, cheese) per day, or a limited dairy diet of 3 or fewer servings of nonfat milk. After 12 weeks of eating full-fat dairy, there was no eﬀect on cholesterol, triglycerides, or blood pressure. However, the 3.3 servings of low-fat dairy group did trend towards a slight improvement in systolic blood pressure.
