ABSTRACT
OBJECTIVES: Whole grains (WG) have been widely recognized as healthy foods but few prospective studies have examined WG foods consumption and all-cause dementia and Alzheimer’s disease (AD) dementia. This pilot study aimed to investigate the relationship between WG and dementia.
METHODS: 2958 subjects from the Framingham Offspring cohort were included with the Food Frequency Questionnaire (FFQ) to assess their diet intake. And multivariate Cox proportional regression was conducted to examine the relations.
RESULTS: After an average follow-up of 12.6 years, 322 all-cause dementia were documented, including 247 AD dementia. In the fully adjusted model, participants in the highest vs. the lowest quintiles of WG consumption had lower risks of all-cause dementia (HR, 0.72; 95% CI, 0.53-0.84; P for trend <0.001) and AD dementia (HR, 0.64; 95% CI, 0.47-0.80; P for trend <0.001).
CONCLUSIONS: High consumption of WG foods is associated with decreased risks of all-cause dementia and AD dementia.t disease mortality. Our findings are from a preliminary study and need to be confirmed in comprehensive settings and integrated statistical methods.
