The nutrition-brain connection: Nutritional status and cognitive decline

Abstract

Cognitive impairment and dementia are not an inevitable consequence of the aging process. Implementation of preventable health care strategies that include evidenced-based dietary plans can greatly reduce the incidence and delay of cognitive decline. Epidemiological studies and randomized clinical trials have demonstrated that the quality of an individual's diet is related to his or her risk for common mental disorders and cognitive performance. Current research has shown supportive evidence for several antioxidant and nutrient-rich dietary patterns that help maintain cognitive health. These include the MeDI dietary plan, the DASH diet, and the MIND dietary plan, which share foundational components of both the MeDI and DASH diets, with an emphasis on green leafy vegetables.
