Recent findings from a large Swedish study have sparked interest in the relationship between cheese consumption and
dementia risk, particularly among middle-aged and older adults. This research followed 27,670 participants over 25
years, revealing that those without genetic risk factors for Alzheimer’s disease who consumed over 50 grams of full-fat
cheese daily exhibited a 13%–17% lower risk of developing the condition. Similarly, consuming more than 20 grams of
full-fat cream was linked to a 16%–24% lower risk of dementia overall.
This study challenges conventional public health guidelines that have long advocated for low-fat dairy options to
mitigate cardiovascular risks. The relationship between heart disease and dementia is complex, as both conditions share
several risk factors, including hypertension, diabetes, and obesity. Notably, previous research has suggested that
cheese consumption may be associated with a lower risk of heart disease, further complicating the dietary narrative
surrounding full-fat dairy products.
However, it is essential to interpret these findings with caution. The benefits observed were not consistent across all
demographics. Specifically, no reduction in dementia risk was identified among individuals with known genetic
predispositions to Alzheimer’s. This suggests that while cheese may offer protective benefits for some, it is not a
The geographic context of these findings is also significant. Studies conducted in Asian populations often show more
favorable outcomes related to dairy consumption for cognitive health, potentially due to lower overall dairy intake in
these regions. For instance, a Japanese study indicated a reduced dementia risk among participants consuming cheese, but
the low average intake complicates the direct applicability of these results to populations with higher cheese
This divergence in findings highlights a critical gap in our understanding of dairy's role in brain health. As public
health agencies grapple with dietary recommendations, these mixed results necessitate a nuanced approach. While the
prospect of full-fat dairy as a cognitive health ally may seem promising, it is vital to continue research to delineate
the effects of different dairy types and consumption levels on long-term health outcomes.
Furthermore, this discourse raises questions regarding dietary guidelines at a systemic level. If full-fat dairy does
not pose the cardiovascular risks once thought, public health policies may need reevaluation. Health systems must
consider how these insights can inform dietary guidelines, especially in light of the rising rates of dementia and
cognitive decline in aging populations worldwide.
In summary, while the association between full-fat cheese and reduced dementia risk is intriguing, it is imperative to
conduct further research to understand the complexities of dairy consumption within diverse populations. As we navigate
this evolving landscape, public health messaging must remain grounded in robust evidence, recognizing both the potential
benefits and limitations of dietary choices in relation to cognitive health.
