The secret to preventing and slowing down Alzheimer's?

A cup of green tea followed by a jog could stave off or slow the progression of Alzheimer's disease, a study claims.
Researchers discovered a green tea extract, called ECGC, slowed the progress of the condition when combined with physical activity.
Mice allowed to exercise after being given ECGC showed 'remarkable' improvement in cognitive function and memory retention.
And the University of Missouri researchers now believe further study of a particular compound in the drink could lead to new treatments for the illness. 
Grace Sun, professor of biochemistry at the University of Missouri, said: 'Oral administration of the extract, as well as voluntary exercise, improved some of the behavioural manifestations and cognitive impairments of Alzheimer's.'
Plaques and tangles in the brain are two of the main features of Alzheimer’s disease. The third is the loss of connections between nerve cells (neurons) in the brain.
