Full-fat dairy linked to lower dementia risk in 25-year Swedish study

A 25-year Swedish study of 27,670 adults found that higher intake of full-fat cheese (>50 g/day) was associated with a 13%–17% lower risk of Alzheimer's in those without a genetic risk, while higher full-fat cream (>20 g/day) was linked to a 16%–24% lower risk of dementia overall; no stronger links were found for low-fat dairy. The findings likely reflect healthier overall diets and lifestyle, possible substitution effects, and population differences, not a causal protective effect of dairy. Researchers also accounted for early dementia by excluding cases at baseline and reanalyzing after removing early incident cases.
