Why choosing low-fat dairy is not necessarily better for your health
Summary
New research shows that low-fat dairy products may not be healthier than full-fat dairy. A study with overweight adults found that eating full-fat dairy daily did not cause weight gain or raise cholesterol, and it might even improve blood pressure and nutrient intake.Key Facts
- Researchers at the University of Toronto studied 74 overweight adults from 2020 to 2023.
- Participants were divided into three groups: low-dairy calorie restriction, normal diet with three servings of full-fat dairy, and unrestricted diet with three servings of full-fat dairy.
- After 12 weeks, there were no big differences in weight, body fat, or cholesterol between groups.
- Eating full-fat dairy helped improve blood pressure and increased intake of calcium, protein, and vitamin D.
- Traditional advice suggests low-fat dairy is better because full-fat dairy has saturated fat, which can raise bad cholesterol (LDL).
- However, recent studies show full-fat dairy does not increase heart disease risk.
- Replacing saturated fat in dairy with healthier fats like those in nuts and vegetable oils can lower heart disease risk.
- The study challenges common dietary guidelines in the US and Canada that recommend low-fat dairy products.
