What dairy products were linked to a lower dementia risk in the Swedish study?

The Swedish study found that regular consumption of full-fat cheese and cream was associated with a lower risk of dementia.

Does consuming full-fat cheese reduce dementia risk for everyone?

The study indicated that the risk reduction associated with full-fat cheese was primarily observed in individuals who did not carry a known genetic risk for dementia.

Were milk or yogurt also found to reduce dementia risk?

No, the study did not find a similar protective effect for milk (whether low-fat or high-fat) or fermented milk products like yogurt.

Full-Fat Dairy Linked to Lower Dementia Risk

A two-decade study in Sweden involving over 27,000 adults has uncovered a potential link between consuming certain full-fat dairy products and a decreased risk of dementia. Researchers observed that regular intake of full-fat cheese and cream was associated with a lower likelihood of developing dementia.

Specifically, individuals who consumed more than approximately 50 grams of full-fat cheese daily experienced a 13 to 17 percent lower risk of Alzheimer's disease. This protective effect was noted particularly in participants without a known genetic predisposition to the condition. The study, published in December 2025, also found a similar trend with full-fat cream.

Participants consuming over 20 grams of full-fat cream daily showed a 16 to 24 percent reduced risk of overall dementia. However, this association was not observed with milk (low-fat or high-fat) or fermented dairy products like yogurt. Researchers acknowledge that individuals who consumed more full-fat dairy also tended to have healthier lifestyles overall.
