Adherence to the Mediterranean Diet, cognitive status and cognitive decline in women

Adherence to the Mediterranean Diet: Cognitive status in womenIn a large-scale prospective epidemiological study published on Journal of Nutrition a research team examined associations of long-term adherence to the Mediterranean Diet (adherence was based on intakes of: vegetables, legumes, fruits, nuts, whole grains, fish, red and processed meats, moderate alcohol, and the ratio of monounsaturated fatty acids:saturated fatty acids) and subsequent cognitive function and its decline.
The participants, 16,058 women from the Nurses’ Health Study, aged ≥70 y, underwent cognitive testing 4 times during 6 y.
The study showed that long-term Mediterranean Diet adherence was related to moderately better cognition but not with cognitive decline in this very large cohort of older women.
