“There’s a growing body of evidence linking elevated blood sugar to memory problems.”
Mainstream media is catching on, folks. The quote above, taken from this story from NPR over three years ago, is reflective of the growing awareness among the medical community and laypeople alike that there might actually be something to the wild and crazy notion of Alzheimer’s disease and cognitive impairment as “type 3 diabetes” or “diabetes of the brain.” I have written about this over and over again and need not rehash the details here. (If you want to know the full story, consider purchasing my book, The Alzheimer’s Antidote.) Even The New York Times published a piece just the other day profiling a famous chef who is using a low-carb, high-fat diet to fight dementia. (Shout out to liberal use of butter abd MCT oil in her morning coffee!)
The NPR article is pretty good. It gets the point across while being very succinct – a feat I have proven I am totally incapable of. What I like best about it is that it references this paper, the key finding of which is that elevated blood glucose may be a risk for dementia even at levels lower than the diabetic range. This is not news to me, and probably not to you, but it’s nice to see this getting out to the general public, among whom it probably is news. (Or should have been a few years ago when this came out.) It’s not news to us because you and I already know that hyperinsulinemia alone—not high glucose, but high insulin—is an independent risk factor for developing Alzheimer’s disease. In fact, compared to people with “normal” insulin levels, those who are not diabetic but are hyperinsulinemic have double the risk of developing AD.
