Full-fat dairy cleared in new study challenging diet advice

Can adults eat full-fat dairy every day without harming health? A new 12-week study from researchers at the University of Toronto found that adults consuming three daily servings of full-fat dairy experienced no significant changes in body weight, body fat or cholesterol levels compared with those consuming less dairy. Why does the research matter? Many dietary guidelines recommend low-fat dairy because full-fat products contain saturated fat, which has traditionally been linked to higher cholesterol and cardiovascular disease risk. The new findings add to growing evidence suggesting dairy fats may behave differently from saturated fats in other foods. What is the dairy matrix hypothesis? Researchers argue that dairy's unique structure, known as the dairy matrix, influences how fats and nutrients are digested and absorbed. The interaction between dairy proteins, fats and micronutrients may help explain why some studies find neutral or even positive health outcomes from full-fat dairy consumption. What else did the study find? Participants consuming more dairy recorded higher intakes of calcium, protein and vitamin D, alongside lower blood pressure, suggesting potential nutritional benefits beyond simply providing energy and fat.
