Associations of Dietary Decanoic Acid Intake With Cognitive Function in the Elderly and the Mediating Effects of Hypertension and Diabetes: An Analysis From NHANES 2011–2014

Key Points

DDA intake is positively associated with global cognitive function in older adults, suggesting potential cognitive benefits.
Hypertension and diabetes partially mediate the relationship between dietary decanoic acid and cognitive function.
The study used a cross-sectional design based on NHANES data from 2011 to 2014, emphasizing the need for further research.
Findings suggest that dietary adjustments may enhance cognitive function, yet causation remains uncertain due to design limitations.

Abstract

DDA intake is positively associated with global cognitive function in older adults. Hypertension and diabetes may partially mediate this relationship. The cross-sectional study design limits causal inference, and prospective or interventional studies should be conducted in the future.
