Alzheimers (and other dementias) have been called Type III diabetes. Even moderate blood sugar elevations can damage the brain. Sugar is addictive. Kick the habit!

The Startling Link Between Sugar and Alzheimer’s
A high-carb diet, and the attendant high blood sugar, are associated with cognitive decline.
In recent years, Alzheimer’s disease has occasionally been referred to as “type 3” diabetes, though that moniker doesn’t make much sense. After all, though they share a problem with insulin, type 1 diabetes is an autoimmune disease, and type 2 diabetes is a chronic disease caused by diet. Instead of another type of diabetes, it’s increasingly looking like Alzheimer’s is another potential side effect of a sugary, Western-style diet.
In some cases, the path from sugar to Alzheimer’s leads through type 2 diabetes, but as a new study and others show, that’s not always the case.
A longitudinal study, published Thursday in the journal Diabetologia, followed 5,189 people over 10 years and found that people with high blood sugar had a faster rate of cognitive decline than those with normal blood sugar—whether or not their blood-sugar level technically made them diabetic. In other words, the higher the blood sugar, the faster the cognitive decline.
But she says there are several theories out there to explain the connection between high blood sugar and dementia. Diabetes can also weaken the blood vessels, which increases the likelihood that you’ll have ministrokes in the brain, causing various forms of dementia. A high intake of simple sugars can make cells, including those in the brain, insulin resistant, which could cause the brain cells to die. Meanwhile, eating too much in general can cause obesity. The extra fat in obese people releases cytokines, or inflammatory proteins that can also contribute to cognitive deterioration, Roberts said. In one study by Gottesman, obesity doubled a person’s risk of having elevated amyloid proteins in their brains later in life.
Roberts said that people with type 1 diabetes are mainly only at risk if their insulin is so poorly controlled that they have hypoglycemic episodes. But even people who don’t have any kind of diabetes should watch their sugar intake, she said.
“Just because you don’t have type 2 diabetes doesn’t mean you can eat whatever carbs you want,” she said. “Especially if you’re not active.” What we eat, she added, is “a big factor in maintaining control of our destiny.” Roberts said this new study by Xie is interesting because it also shows an association between prediabetes and cognitive decline.
That’s an important point that often gets forgotten in discussions of Alzheimer’s. It’s such a horrible disease that it can be tempting to dismiss it as inevitable. And, of course, there are genetic and other, non-nutritional factors that contribute to its progression. But, as these and other researchers point out, decisions we make about food are one risk factor we can control. And it’s starting to look like decisions we make while we’re still relatively young can affect our future cognitive health.
“Alzheimer’s is like a slow-burning fire that you don’t see when it starts,” Schilling said. It takes time for clumps to form and for cognition to begin to deteriorate. “By the time you see the signs, it’s way too late to put out the fire.”
