Diet May Moderate the Relationship Between Arterial Stiffness and Cognitive Performance in Older Adults

In a study aimed to explore the relationship between diet, arterial stiffness, glucose control, and cognitive performance in older adults at risk of cognitive decline, Sarah Gauci and colleagues reported that arterial stiffness predicted cognitive performance independently, while no relationship was observed between glucose control and cognitive outcomes. The results indicate that diet alone did not predict cognitive performance, but it moderated the relationship between arterial stiffness and cognition. The study suggests that diet and arterial stiffness may act together to impact cognition and that exploring the interaction between dietary factors and other health factors could help reduce the impact of unhealthy brain aging.
