Houston: People who drink three or more servings of fruit and vegetable juices per week will reduce their risk of developing Alzheimer's disease by 76 per cent, a study says.
Researchers found that people who drank three or more servings of fruit and vegetable juices per week had a lower risk of developing Alzheimer's disease than those who drank juice less than once per week.
The researchers followed a subset of subjects from a large cross-cultural study of dementia, called the Ni-Hon-Sea Project, which investigated Alzheimer's disease and vascular dementia in older Japanese populations living in Japan, Hawaii and Seattle.
For the current study, called the Kame Project, the researchers identified 1,836 dementia-free subjects in the Seattle population and collected information on their dietary consumption of fruit and vegetable juices.
They then assessed cognitive function every two years for up to 10 years.
After controlling for possible confounding factors like smoking, education, physical activity and fat intake, the researchers found that those who reported drinking juices three or more times per week were 76 per cent less likely to develop signs of Alzheimer's disease than those who drank less than one serving per week.
The benefit appeared particularly enhanced in subjects who carry the apolipoprotein E-4 allele, a genetic marker linked to late-onset Alzheimer's disease the most common form of the disease, which typically occurs after the age of 65.
