Dairy products are enjoying a renewed spotlight in wellness conversations, with yogurt often hailed as a modern superfood and full-fat options gaining attention from health experts. This shift prompts many to wonder: has cheese become a health food, and what does this mean for concerns like LDL cholesterol, long associated with heart disease? According to cardiologist Dariush Mozaffarian, MD, director of the Food is Medicine Institute at Tufts University, “Food is complicated. You can’t just think of some single thing like saturated fat content or even calories and make a decision.” His perspective, widely cited in media, suggests full-fat dairy may be as beneficial as low-fat versions, challenging traditional dietary advice.
Federal guidelines have long recommended three daily servings of dairy, but a new directive encourages full-fat consumption. However, Frank Hu, MD, PhD, chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health, cautions that this could lead to exceeding the daily saturated fat limit of less than 10% of total calories, especially for those who also eat other high-saturated fat foods like animal protein. “And then they encourage people to use butter or beef tallow instead of vegetable oils for cooking. And so that’s why the math really doesn’t add up,” he notes, highlighting a potential conflict in dietary recommendations.
Expert Perspectives on Saturated Fat and Dairy
Mozaffarian proposes a nuanced approach: exclude saturated fat from full-fat dairy when calculating the 10% limit, a method the government has used in adding whole milk to school lunches. He argues that evidence is “very clear that there’s really no advantage to consuming low-fat dairy over full-fat dairy. And there could be some advantages to consuming whole-fat dairy over low-fat dairy, although that needs to be studied more.” In contrast, Hu disagrees, stating, “Saturated fat is saturated fat. It’s the same molecule. It’s like saying, ‘Oh, you shouldn’t count added sugar in yogurt because overall, yogurt is healthy.’” This debate reflects a broader pushback from nutritionists who advocate for a more conservative stance, as seen in guidelines that equally advise low-fat, nonfat, and dairy alternatives.
The American College of Cardiology continues to recommend prioritizing plant-based foods and limiting all saturated fat sources to 10% of daily calories, underscoring the ongoing tension between emerging science and established health advice.
What the Research Says About Full-Fat Dairy
Dairy’s health benefits are well-documented, with Mozaffarian pointing out that “Milk lowers blood pressure, and that’s associated with lower risk of stroke. Cheese is actually associated with a lower risk of diabetes. Yogurt is associated with lower weight gain and a lower risk of diabetes.” The key question, he says, is whether to choose whole-fat or low-fat options. Recent reviews of over 100 studies by the 2025 advisory committee found limited evidence that switching to higher-fat dairy increases cardiovascular disease risk, but also supported replacing saturated fats from sources like butter and red meat with plant-based alternatives to reduce heart problems.
Penny Kris-Etherton, PhD, RD, a retired professor of nutritional sciences at Penn State University, notes that the term “limited” is crucial, as many studies were short-term or conducted outside the U.S., potentially limiting applicability to Western diets. Hu adds caveats: benefits may reflect higher socioeconomic status or reduced refined carbohydrate intake among dairy consumers, and it’s important to consider what foods are replaced by dairy in studies.
Practical Tips for Making Dairy Choices
Experts agree on a practical framework for dairy decisions, emphasizing an “eat this, not that” approach. Mozaffarian suggests asking “Compared to what?” when selecting dairy. For example, cheese may be healthier than sugary drinks or processed foods but less beneficial than fruits and vegetables. He advises swapping sweetened low-fat dairy for whole-fat plain versions, as “It’s better to have whole-fat plain versions than sweetened low-fat versions.” Those already eating plain low-fat dairy need not switch, but if preference leans toward whole-fat, “then by all means switch.”
Kris-Etherton supports this individualized strategy, noting that if someone dislikes skim milk, including some full-fat dairy can provide essential nutrients and be a better choice than sugar-sweetened beverages. She highlights that whole milk may promote fullness due to slower digestion, and cheese has been linked to reduced waist circumference in some studies, though calories should be monitored. For those increasing full-fat dairy intake, she recommends a cholesterol check after six months and points to the American Heart Association’s Life’s Essential 8 program for overall cardiovascular health.
Ultimately, Mozaffarian concludes that there isn’t enough evidence to universally recommend switching from low-fat to whole-fat dairy, but whole-fat options can be a healthier alternative to less nutritious foods. Kris-Etherton reinforces this, stating, “What the research has shown is that people who have all of those in check, you have a lower prevalence of cardiovascular disease. So you can’t just say, ‘Oh, well, one really isn’t very important.’” This balanced perspective encourages mindful choices tailored to individual diets and health goals.
