Whole Grains, Nuts, Legumes Protect Cognitive Function

Scientists at Utah State University and Duke University assessed the cognitive function of 3831 men and women 65 or older over an 11-year period, and compared their cognitive abilities with their diet makeup. They found that higher adherence to both the DASH diet and the Mediterranean diet corresponded with higher cognitive abilities, and that “whole grains and nuts and legumes were positively associated with higher cognitive functions and may be core neuroprotective foods common to various healthy plant-centered diets around the globe.”

Whole Grains Linked with Better Cognitive Function

Researchers analyzed the food intake and cognitive function in a group of 3,831 older adults in Utah over 11 years. Those most closely following a DASH diet (a healthy diet used to treat hypertension that emphasizes fruits, vegetables, whole grains, low fat dairy, and limited sweets and salt) or Mediterranean diet at the start of the study were found to have consistently better cognitive function than those not following those diets. In particular, whole grains, nuts, and legumes were all linked with better cognitive function, and the researchers concluded that these “may be core neuroprotective foods common to various healthy plant-centered diets around the globe.”
