Increases in adherence to a simplified Mediterranean diet predicts improved next day cognitive functioning

These findings show that day-to-day shifts in sMD adherence have implications for micro-longitudinal changes in cognition for middle-aged and older adults, suggesting even small changes in sMD could add up and contribute to healthy cognitive aging over time. Simple changes such as increasing fruit, vegetable, and fish intake and reducing sugar-sweetened beverage consumption may thus result in improved cognitive functioning over even very brief time periods.
