Impact of the Mediterranean Diet on Cognitive Function in Type 2 Diabetics

In conjunction with adequate disease management, following the Mediterranean diet could benefit memory function in type 2 diabetes mellitus (T2DM) patients. Data from the Boston Puerto Rican Health Study on 913 patients (42.6% with T2DM) were classified by baseline glycemic control (uncontrolled [hemoglobin A1c ≥ 7% {53 mmol/mol}] versus controlled). Researchers defined Mediterranean diet score (MeDS), Healthy Eating Index, Alternate Healthy Eating Index, and Dietary Approaches to Stop Hypertension scores. Only a higher MeDS score was associated with significant two-year improvement in global cognitive function in patients with T2DM, but not those without T2DM. The findings did not apply to patients with uncontrolled or poor/declined glycemic control. In non-T2DM patients, all diet quality scores were associated with greater two-year memory function.
