I don't know how much faith I'd put in this, but it's another reason to avoid fast food unless you're on the road, pressed for time and really hungry.
Research on mice links fast food to Alzheimer's
"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."
