title: Cognition and nutrition.
abstract: OBJECTIVE
  Aging is associated with a decline in cognition. This review examines the available data on the effects of nutrition on cognitive impairment. It also explores the mechanism(s) by which food may enhance memory.
  
  
  RESULTS
  An increasing body of evidence has supported the role of the Mediterranean diet and extra-virgin olive oil in protecting cognition. A number of nutritional formulations to improve deteriorating memory are being studied. Undernutrition is associated with cognitive decline. Hyperglycemia and hypertriglyceridemia cause cognitive impairment.
  
  
  CONCLUSIONS
  There are increasing data to support the role of nutrition in maintaining cognition.
