Maybe you’ve heard that saturated fat isn’t actually harmful…or that it’s fine if it’s from dairy. We’re here to clear up the confusion and answer your questions about saturated fat.
An extremely robust body of evidence shows that saturated fat raises LDL (“bad”) cholesterol and that LDL is a direct cause of—not just a risk factor for—heart disease, according to the American Heart Association, the American College of Cardiology, and others.
Saturated fat is commonly found in higher amounts in meat; full-fat dairy products like whole milk, ice cream, cheese, and butter; coconut oil; and palm oil. Mixed dishes and processed foods that contain these ingredients (for example: sandwiches, pizza, desserts) are major sources of saturated fat in our diets. Unsaturated fats are relatively higher in plant-based foods, like avocados, nuts, seeds, and plant-based oils like olive, canola, soybean, sunflower, and flaxseed. Omega-3 polyunsaturated fats are also found in fish and shellfish.
But it also matters what you replace saturated fat with. Study after study shows that the risk of heart disease is slashed by replacing saturated fats with polyunsaturated fats, like those found in nuts, seeds, and vegetable oils. Replacing saturated fats with refined carbs or trans fats will not lower risk of heart disease.
Studies report contradictory findings on the health effects of whole and non-fat dairy. More research is needed. Given the harms of saturated fat overall, it remains reasonable to recommend mostly low- and nonfat dairy options, though there is likely room for some whole-fat dairy in healthy diets.
What's important to remember is that the meat and dairy industries fund studies that are often designed to show no harm of saturated fats. This approach sows doubt about the established harms of saturated fat.
