Recent research conducted in Sweden has identified a potential link between the consumption of high-fat dairy products, specifically high-fat cream and cheese, and a reduced risk of developing dementia. The study, published in the journal Neurology, involved a cohort of 27,670 participants with an average age of 58, who were monitored over an average of 25 years. The findings suggest that those who consumed 20 grams or more of high-fat cream daily had a 16% lower risk of dementia compared to non-consumers. Similarly, participants consuming 50 grams or more of high-fat cheese daily exhibited a 13% lower risk than those consuming less than 15 grams.
Notably, the study found no significant association with low-fat dairy products or other dairy forms like butter and yogurt. Participants who consumed more high-fat cheese had a reduced risk of vascular dementia and, among those not carrying the APOE e4 gene variant, a lower risk of Alzheimer’s disease was also observed.
However, the researchers caution that the study does not definitively establish causation, and the observed associations are relatively modest. They highlighted the potential influence of healthy user bias, as individuals who consume high-fat dairy may also engage in other health-conscious behaviors.
The research team calls for further studies to confirm these findings and explore the implications of high-fat dairy on brain health, emphasizing that not all dairy products may provide the same health benefits. The results invite a re-evaluation of long-held dietary guidelines regarding fat consumption, particularly in the context of brain health.
