Eating Whole Grains Linked with Slower Cognitive Decline

Good nutrition can help support brain health and healthy aging, and it’s increasingly clear that whole grains are an important part of the equation. In a study of 3,326 older adults (average age 75), those eating three or more servings of whole grains per day had a slower rate of decline in global cognition, perceptual speed, and episodic memory compared to those who ate fewer than one serving per day. These results were statistically significant for the group as a whole and for African American participants (who made up 60% of the study population), but did not quite reach statistical significance for white participants (who made up a smaller proportion of the study population).
