When it comes to many things, we already know that too much of a good thing can be a bad thing. Well, now researchers are giving us another reason to beware of a poor diet. A new study says insulin resistance, often linked to weight gain and obesity, could be linked to cognitive decline and Alzheimer’s.
Researchers looked at 150 middle-aged people with an average age of 60, who were at risk for Alzheimer’s, but did not show memory loss at the start of the study. Brain scans revealed that greater insulin resistance was linked to less sugar in key parts of the brain, often affected by Alzheimer’s.
