The nutrition committee of the American Heart Association recognizes the diversity of the biological effects of individual fatty acids and the need to evaluate specific fatty acids related to the risk of coronary heart disease (CHD).1 What’s more, these fats have distinct physiological effects. The fatty acids in whole milk are approximately 62% saturated, 30% monounsaturated, 4% polyunsaturated, and 4% other types such as naturally occurring trans fatty acids, which include conjugated linoleic acid (CLA). More than 400 different fatty acids have been identified in milk fat. “The fats in whole dairy foods are highly complex and may contain beneficial ingredients,” says Adam Lock, PhD, an assistant professor in the department of animal science at Michigan State University. ![]() According to the Dietary Guidelines Advisory Committee, Miller says consumption of milk and milk products-regardless of fat level-is associated with a lower blood pressure and a reduced risk of CVD and type 2 diabetes. “The evidence is fairly strong,” says Greg Miller, president of the Dairy Research Institute and executive vice president of the National Dairy Council. In contrast, emerging research indicates that dairy fat isn’t harmful to heart health as once thought. For example, the 2010 Dietary Guidelines for Americans recommend consuming fewer than 10% of calories from saturated fat and keeping trans fat intake as low as possible by limiting foods that contain synthetic sources of trans fats (eg, partially hydrogenated oils) and other solid fats. Over the past 50 years, evidence linking the intake of certain saturated and trans fats to an increased risk of cardiovascular disease (CVD) has led to the broad generalization that these fats are detrimental to one’s health. In light of recent research, however, nutrition professionals may not need to strictly adhere to these guidelines. When asked about dairy recommendations for people aged 2 and older, most dietitians will advise clients to choose low-fat or fat-free milk, yogurt, and cheese in accordance with MyPlate recommendations for dairy food selections. ![]() Research indicates fats in dairy foods don’t increase the risk of cardiovascular disease and may in fact benefit health. ![]()
