I’ve considered high-carb diets to be dangerous, and this troubling research linking high-carb diets to cognitive decline gives me yet another reason to avoid excessive carbs. Yikes!
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.
