Nashville: Fruit and vegetable juices have the potential to protect against the devastating brain disease Alzheimer’s, according to US scientists.

They examined the effects of drinking fruit and vegetable juices more than three times a week amongst 2,000 people for 10 years and discovered that it reduced the risk of the disease by 76 per cent compared to those whose intake was less.

Doctors believe that the findings confirm that diet can play a huge role in whether you get the disease. It is thought that protective substances in fruit and vegetables known as polyophenols, protect the brain from accumulations of bad proteins.

The study carried out at Vanderbilt University, Nashville, Tennessee, and participants consumed juice with high concentrations of pulp and peel which contain the most polyphenols.
