Research regarding the relationship between milk fat content and cardiovascular health has presented conflicting findings. A large-scale Norwegian study involving over 73,000 participants indicated that high milk consumption was associated with a higher risk of death, with the risk of cardiovascular death being roughly 12% higher among heavy consumers. The study suggested that low-fat or skimmed milk was associated with lower mortality risks compared to whole milk, potentially due to saturated fat intake.

However, subsequent nutritional reassessments have challenged these perspectives. A 2025 study published in The American Journal of Clinical Nutrition found no significant difference in cardiovascular risks between consumers of whole milk and those consuming low-fat varieties. Experts have suggested that the historical criticism of whole milk may have overstated its risks and that reducing the intake of ultra-processed, nutrient-poor foods is a more critical factor for heart health than the specific fat content of milk.

## Timeline

### 2026-09-27: Nutrition experts reassess health impacts of whole milk

New research suggests whole milk does not significantly increase cardiovascular risks compared to low-fat options, emphasizing the importance of avoiding ultra-processed foods instead.
