Study links nutrition to brain health and cognitive aging

A new study of older adults finds an association between higher blood levels of phosphatidylcholine, a source of the dietary nutrient choline, and greater cognitive flexibility, the ability to regulate attention to manage competing tasks. The study also identified a brain structure within the prefrontal cortex, a region at the front of the brain, that appears to play a role in this association.
