Diabetes and Dementia July 6, 2020

There is growing evidence that Diabetes (especially Type 2) is linked to Dementia.

A 2016 study says, “A confluence of factors related to dietary changes, sedentary lifestyle, and an aging population in Western cultures has led to a rapid rise in the incidence of type 2 diabetes, a disease that carries enormous burden in terms of health and economic outcomes. Increasingly, type 2 diabetes is recognized as a major contributor to cognitive decline and dementia in older adults.”

In other words, diabetes and dementia are growing together at the same time, with some of the same causes.  A “sedentary lifestyle” means we sit too much, when we should try to be more active. An “aging population” – well, we can’t help that, I’m already ten minutes older than when I started to write this.

But diet we can do something about.

A 2020 study advises, “The more carbohydrate eaten in a meal, the more sugar is absorbed into the bloodstream and the higher the blood sugar will be.

“Although very few people would agree that sugary foods are good for you, some foods that we think of as “healthy” — such as fruit — actually have a lot of sugar. And many people don’t know that starchy foods — such as bread, rice, pasta, and potatoes — quickly turn to sugar when you digest them.”

It also says, “Dietary fat has very little effect on blood sugar. However, we seldom eat fat all by itself. Some foods, like cheese, are made up of mostly protein and fat. These foods probably won’t raise your blood sugar very much.

“But other foods, like doughnuts and French fries, are made up mostly of carbohydrate and fat. Because they’re high in carbs, these foods are likely to significantly raise your blood sugar.”

Some of our grandmothers knew that foods high in carbs, like sugar, flour, potatoes and rice were “fattening.” Now we know they increase our blood sugar, which can lead to diabetes and potentially to dementia.
