A new study led by an Indian-origin researcher established that eating walnuts everyday can stave off dementia.

Dr. Abha Chauhan and his colleagues at New York State Institute have carried out the study and found eating walnuts on a habitual basis can keep one's mental dexterity up. Vitamin E and flavonoids in walnuts in fact assist in annihilating injurious free radical chemicals that cause dementia, the researchers said.

Dr. Chauhan was quoted saying "Walnuts may have a beneficial effect in reducing the risk, delaying the onset or slowing progression of Alzheimer's disease”.

The researchers have based their conclusion on a study of experimentation on laboratory rodents a few of whom were fed with walnuts. It was instituted that feeding the nuts to mice with Alzheimer's disease kept their cerebral skills high.

But those mice without them underwent a remarkable loss in learning, memory and physical and emotional power. The results signify a penetration in the study of how the brain putrefied.

Another study showed the benefits of tea, coffee and exercise.

A study by Harvard Medical School of 1,200 old people demonstrated ‘temperate to heavy’ exercise paid for a 40% lower threat of dementia.

A second study recommended a regular cup of tea or coffee could stave off mental cry off.
