Fasting for regular periods could help protect the brain against degenerative illnesses, according to US scientists.

Researchers at the National Institute on Ageing in Baltimore said they had found evidence which shows that periods of stopping virtually all food intake for one or two days a week could protect the brain against some of the worst effects of Alzheimer's, Parkinson's and other ailments.
