A recent 12-week study from the University of Toronto reveals that consuming full-fat dairy products daily does not negatively impact body weight, cholesterol, or metabolism, challenging common dietary guidelines.
- No weight gain or cholesterol rise from full-fat dairy
- Improved blood pressure and nutrient intake observed
- Supports need for whole-food dietary guidelines
What happened
The University of Toronto conducted a 12-week study involving 74 overweight or obese adults who were assigned to different diet groups. Some followed calorie restriction with low dairy intake, while others consumed three daily servings of full-fat dairy under energy-neutral or unrestricted diets. Participants were provided with full-fat dairy products and guided by the Canada food guide throughout the study period.
Results showed no significant differences in weight gain, body composition, or cholesterol levels between those who consumed three servings of full-fat dairy and those with low dairy intake. In addition, participants eating full-fat dairy had lower blood pressure and higher consumption of essential nutrients such as calcium, protein, and vitamin D.
Why it feels good
This study challenges long-held concerns that saturated fats found in full-fat dairy products necessarily increase cardiovascular risk. Researchers believe the unique structure of dairy — where proteins, fats, and nutrients are bound together — allows for a slower, more beneficial absorption of these elements, supporting the so-called dairy matrix hypothesis.
The findings are especially encouraging for older adults, who often face difficulties meeting their nutrient needs without gaining weight or risking chronic diseases. Full-fat dairy provides a familiar, nutrient-dense option that can support healthy aging without adverse metabolic effects.
What to enjoy or watch next
Given these positive findings, health enthusiasts and cheese lovers alike can feel more confident including full-fat dairy in their diets. Enjoying a variety of cheeses or yogurts may not only satisfy taste buds but also contribute to better nutrient intake and heart health.
Future research will continue to explore the broader impacts of dairy on long-term health, including its potential role in preventing conditions like dementia. Meanwhile, incorporating full-fat dairy thoughtfully into balanced meals could be a delicious and healthful choice.
