Childhood Diet Linked to Long-Term Cognitive Health

The findings of a study on the long-term effects of diet were presented at the June 2024 meeting of the American Society for Nutrition, in Chicago. The study tracked diet and cognitive abilities of more than 3,000 adults enrolled in a British survey since 1946. The participants’ diet was analyzed at five points in time, and their cognitive ability at seven points. The researchers found that higher dietary quality was closely linked with greater cognitive ability, including working memory, processing speed and general cognitive performance. Those with the highest cognitive abilities over time ate more vegetables, fruits, legumes and whole grains, and less sodium, added sugars and refined grains. Only 8 percent of participants with low-quality diets sustained high cognitive abilities. The results of the study suggest that the cumulative effects of diet are linked to how sharp the mind is as we age.
