Sacrificial victims in yet another animal experiment, the rats in Suzanne de la Monte’s study were demented. The researcher told New Scientist they splashed around aimlessly, unable to remember where to find the submerged safety platform.
The Brown University scientists had used a chemical to block insulin in the rats’ brains. The rodents literally could not find their way out of the maze. Postmortems revealed brains dotted with pink plaques. Neurons were crumbling. Connections had collapsed.
De la Monte had seen brain devastation before, in a 2005 study that led to the first use of the term “Type 3 diabetes.” That study showed insulin is produced in the brain as well as the pancreas. When the brain stops producing enough insulin, it slides inexorably into the fog of dementia.
Other studies had already shown links between a bad diet and Type 2 diabetes, where cells become insulin resistant and stop being able to convert sugar into energy. Discovering the brain was the source of a different kind of diabetes offered important clues into dementia.
A different study published in the September 20 Neurology tracked over 1,000 people in Japan and determined diabetes was a “significant risk factor for the development of dementia, especially Alzheimer’s disease, in (the) general public.”
In every case, researchers draw a bead on diet as a significant factor. A diet heavy in sugar and fat contributes an avoidable risk factor. We dread Alzheimer’s, yet stay on the collision course.
