Low-protein, high-carb diet may help ward off dementia

Diet tested on mice proves more beneficial in some cases than restricting calories

Researchers at Sydney University's Charles Perkins Centre fed the mice complex carbohydrates derived from starch, and casein protein, which is found in cheese and milk.
