But in a first-of-its-kind study, scientists have seemingly cemented the connection between a diet deficient in flavanols – a plant-based compound known for its antioxidant benefits, among others – and age-related memory loss. What's more, they found that boosting a poor diet with flavanol supplements could be key in reversing this memory loss.

It supports the growing consensus among scientists that, much like developing brains in childhood, aging brains require specific nutrition to stave off cognitive decline.
