Some See Fasting as Alzheimer’s Prevention

November 7, 2013 | By Lorenzo Mejia

Studies in which mice were made to fast suggest that periodic fasting can be a way to reduce the risk of cognitive impairment.

A number of books have popularized the trend and build on promising research on mice conducted by the National Institute of Aging.

One study suggested that fasting increased the production of a protein called brain-derived neurotrophic factor, or BDNF, which enhances learning and memory.  Other studies have suggested that fasting triggers cell autophagy, a process by which cells deprived of food begin to consume themselves.  This self-consumption helps remove the detritus of metabolism, which some believe is what beta amyloid plaques are.

More research needs to be done.  Still the evidence points in a consistent direction:  too may calories can be bad for you.   Sounds like old news.
