Dietary interventions as a neuroprotective therapy for the delay of the onset of cognitive decline in older adults: Evaluation of the evidence

摘要

Background: The relationship between nutrition and cognitive functioning is unclear, especially in elderly populations as many elderly people with cognitive impairment have low blood levels of some nutrients even in the absence of malnourishment. The objective of this review was to assess the evidence from systematic reviews of human studies on the effectiveness of dietary interventions as monotherapies in delaying the onset of cognitive decline in older adults.
