Generous consumption of vegetables may hinder the development of dementia and Alzheimer's disease in older men and women.

This study quantified the risk of dementia and Alzheimer's disease among older men and women on high fruit and vegetable diet. Out of the 1,071 Japanese men and women aged 60 years and above who took part in this study, 464 of them developed dementia and Alzheimer's disease over a follow-up period of 24 years.

Researchers observed that the odds of developing dementia and Alzheimer's disease decreased by 27% and 31% respectively among participants who consumed the highest amounts of vegetables. This study supports increased intake of vegetables as a dietary strategy for the prevention of dementia and Alzheimer's disease.
