Refined Carbohydrates Between Meals Linked to Poor Cognitive Performance

A study in France found that chronic consumption of refined carbohydrates between meals was associated with worse cognitive performance in both men and women. The study was conducted on 95 healthy young adults between 20 and 30 years of age. The study makes a valuable contribution to the scientific knowledge about links between dietary choice and cognitive performance. However, the study design does not allow for any cause-and-effect conclusions.
