Purpose Of Review:
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.
Recent Findings:
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.
Summary:
There are increasing data to support the role of nutrition in maintaining cognition.
