New study: Whole milk does not increase cardiovascular risk

Research on whole milk and cardiovascular indicators

Design and context of the whole milk study

For decades, dietary guidelines have often favored low-fat or skim milk to reduce saturated fat intake and lower the risk of cardiovascular disease. However, new research from the University of Toronto suggests this view may need to be reconsidered in light of emerging scientific evidence. The study, published in The Journal of Nutrition, tracked 74 overweight or obese adults over 12 weeks. Participants were asked to consume 3 servings of whole milk per day.

The results showed that whole milk consumption did not significantly alter body weight, body composition, cholesterol levels, or key metabolic markers related to cardiovascular health. Conversely, the group consuming more dairy products even saw improved blood pressure alongside increased calcium, protein, and vitamin D intake.

According to researchers, dairy fat may behave differently from saturated fats found in many other foods due to the natural food matrix of dairy products, where nutrients interact and influence both digestion and metabolism in the body. This may explain why whole milk does not produce the adverse effects previously assumed.

For the agricultural sector, the research findings have noteworthy implications, as consumer preferences may shift toward greater acceptance of full-fat dairy products. This helps increase value throughout the dairy production chain, from dairy farms to processing companies, especially as demand for nutrient-rich, minimally processed foods grows.

However, the study was relatively small in scale with a follow-up period of only 12 weeks; therefore, larger and longer-term studies are needed to fully evaluate the impact of whole milk on cardiovascular health across diverse populations. At the same time, a balanced diet and a healthy lifestyle remain the most important factors in preventing cardiovascular disease.
