Abstract
This cohort study aimed to analyze the relationship between nut consumption and the risk of all-cause dementia in adults from the United Kingdom (UK). Data from participants in the UK Biobank cohort between 2007-2012 (baseline) and 2013-2023 (follow-up) were analyzed. Baseline information on nut consumption was obtained using the Oxford WebQ 24-h questionnaire. All-cause dementia (i.e. Alzheimer's disease, frontotemporal dementia, or vascular dementia) was assessed at baseline and follow-up through self-reported medical diagnosis, hospitalization, or death records. Hazard regression models were used to estimate the association between nut consumption and the risk of developing all-cause dementia, with adjustments made for sociodemographic, lifestyle, hearing problems, self-rated health, and the number of chronic diseases. Participants with all-cause dementia at baseline were excluded. A total of 50,386 participants (mean age 56.5 ± 7.7 years, 49.2% women) were included in the prospective analyses. The incidence of all-cause dementia was 2.8% (n = 1422 cases). Compared with no consumption, daily nut consumption (> 0 to 3 or more handfuls) was significantly associated with a 12% lower risk of all-cause dementia (hazard ratio = 0.88; 95% confidence interval, 0.77-0.99) after 7.1 mean years of follow-up, regardless of the potential confounders considered. No statistically significant interactions were observed between nut consumption and any of the covariates included in the hazard regression models. Stratified analyses revealed that nut consumption of up to 1 handful of 30 g/day and consumption of unsalted nuts were associated with the greatest protective benefits. The daily consumption of nuts may play a protective role in the prevention of dementia.</p>
