The Link Between High Blood Sugar and Alzheimer’s

The Link Between High Blood Sugar and Alzheimer’s

Could Alzheimer’s really claim the dubious distinction of being a new type of diabetes?

Type 3 Diabetes is a title that has been proposed for Alzheimer’s disease, which results from resistance to insulin in the brain. That’s because there is increasing evidence that a sugary diet and high blood sugar levels don’t just put you at a higher risk for Type 2 diabetes, they could also put you at risk for the most common form of dementia.  

In Canada, nearly six million people have higher than normal blood sugar levels and are considered pre-diabetic. Most will develop Type 2 diabetes within ten years. But increasingly, researchers are showing links between higher blood sugar and the onset of dementia. The conclusion of one study was that people with higher blood sugar levels had a faster rate of cognitive decline, even if they were not diabetic. And both Type 1 and Type 2 diabetics have a higher prevalence of Alzheimer’s than the general population.

Just another reason to adopt a healthier lifestyle that includes a better diet and more exercise. More fruits, vegetables and whole grains with a cut back on refined carbohydrates can help reduce blood sugar levels. So can more exercise. While 30 minutes of moderate activity five days a week is optimal, even short intense bursts of less than two minutes have been shown to have a positive impact.
