A decline in cognitive impairment and dementia risk is associated with frequent consumption of fruits and vegetables.
This study was carried out to determine the effect of high dietary ingestion of fruits and vegetables on cognitive function and dementia risk. Researchers conducted a systematic review on 5 cohort and 4 cross-sectional studies that examined 31,104 subjects and 4,583 incident cases of cognitive impairment and dementia.
The team of investigators found out that subjects who consistently consumed diets high in fruits and vegetables had less chance of suffering cognitive impairment and dementia. Regular intake of 100 grams of fruits and vegetables per day was found to decrease the risk of having dementia and cognitive impairment by 13%. The results of this meta-analysis support the hypothesis that increased consumption of fruits and vegetables may decrease the incidence of dementia and cognitive impairment in the general population.
