But not all saturated fats affect blood cholesterol equally. In some dairy foods, a membrane—called a milk fat globule membrane—surrounds the saturated fats and seems to limit their cholesterol-raising properties.
However, butter is low in this protective membrane, and consequently raises blood cholesterol more than other high-fat dairy products, like full-fat milk, cream, yogurt, or cheese.24 25 26
The U.S. Dietary Guidelines recommend capping saturated fat at less than 10 percent of your calorie intake. A tablespoon of butter contains 7 grams of saturated fat—a third of the recommended daily limit in a 2000 Calorie diet.
