Research tracking nearly 28,000 adults over 25 years links high-fat cheese and cream consumption to reduced rates of cognitive decline.

A large-scale Swedish study spanning more than two decades has found that regular consumption of full-fat dairy products, particularly cheese and cream, is associated with a lower risk of developing dementia.
Researchers followed 27,670 adults for a median of 25 years as part of the Malmö Diet and Cancer cohort, monitoring dietary habits alongside health outcomes through the Swedish National Patient Register. During the study period, 3,208 participants were diagnosed with dementia.
The findings indicate that individuals who consumed more than 50 grams of high-fat cheese daily experienced a 13% lower risk of all-cause dementia and a 29% lower risk of vascular dementia compared to those with minimal intake. Similarly, participants who consumed at least 20 grams of high-fat cream per day showed a 16% reduction in overall dementia risk compared to those who did not consume cream.
In contrast, researchers found no measurable association between low-fat dairy products and dementia risk.
The study also identified a genetic component influencing outcomes. Among participants who do not carry the APOE ε4 gene variant—widely recognized as a major genetic risk factor for Alzheimer’s disease—higher consumption of full-fat cheese was associated with a reduced risk of developing Alzheimer’s specifically. Researchers noted that genetic differences may influence how dietary factors affect brain health.
The study’s authors emphasized that the findings reflect associations rather than direct causation, though the extended follow-up period and large participant group provide a substantial data set for analysis.
The results come as global dementia rates continue to rise. Estimates project a significant increase in cases over the coming decades, underscoring the importance of identifying modifiable lifestyle factors that may influence cognitive health.
Separate research has also pointed to cognitive engagement as a potential protective factor. A study involving more than 19,000 adults age 50 and older found that regular participation in activities such as crossword puzzles and number games was associated with cognitive performance comparable to individuals eight to ten years younger, based on measures of memory, reasoning and attention.
Taken together, the research highlights the role of both diet and mental activity in long-term brain health. While further study is needed to clarify mechanisms, the findings suggest that dietary patterns, genetic factors and cognitive habits may all contribute to differences in dementia risk over time.
