Dairy products and brain structure in French older adults

Br J Nutr. 2023 Sep 11:1-26. doi: 10.1017/S0007114523001551. Online ahead of print.ABSTRACTAmong food groups with putative benefits for brain structures, dairy products (DPs) have been poorly studied. The sample included participants without dementia from the ancillary brain imaging study of the Three-City cohort who were aged 65+ years, had their DPs intake assessed with a Food Frequency Questionnaire at baseline and underwent an anatomical scan 3 years (n=343) or 9 years (n=195) after completing the dietary survey. The frequencies of consumption of total DPs, milk and cheese were not associated with brain structure. Compared to the lowest frequency, the highest frequency of fresh DPs consumption (<0.5 vs. >1.5 times/day) was significantly associated with a lower Medial Temporal Lobe Volume (MTLV) (β = -1.09 cm3, 95% confidence interval -1.83; -0.36) 9 years later. In this population-based study of older adults, the consumption of fresh DPs more than 1.5 times/day was associated with a lower MTLV, which is considered an early biomarker of Alzheimer's disease, 9 years later. This original study should be replicated in different settings before conclusions are drawn.PMID:37694377 | DOI:10.1017/S0007114523001551
