Fast Food Linked to Alzheimer's?

A new study shows a diet rich in fat, sugar and cholesterol could increase the risk of the most common type of dementia.

Mice fed junk food for nine months showed signs of developing the abnormal brain tangles strongly associated with Alzheimer's disease. The findings come from a series of published papers by a researcher at Sweden's Karolinska Institutet

"On examining the brains of these mice, we found a chemical change not unlike that found in the Alzheimer brain," Susanne Akterin, a researcher at the Karolinska Institutet's Alzheimer's Disease Research Center, who led the study, said in a statement.

"We now suspect that a high intake of fat and cholesterol in combination with genetic factors ... can adversely affect several brain substances, which can be a contributory factor in the development of Alzheimer's."
