Is too much blood sugar shrinking your brain?

A recent study, published in Neurology, suggests there is an association between high blood sugar on the high end of normal and brain shrinkage in the areas of the brain “associated with memory and thinking” according to Dr. Gad Marshall was a neurologist at Harvard affiliated Brigham and Women’s Hospital. Previous research has already revealed links between high blood sugar, type II diabetes and brain shrinkage.

This study has found that people whose fasting blood sugar levels are at the high end of normal also have a higher possibility of brain shrinkage. After fasting, defined as six hours or more without eating or drinking anything with calories, the normal fasting blood levels are between 70 to 100 mg/dL. You have pre-diabetes if your fasting blood sugar levels are 100 to 125 mL per deciliter. At this point, you have definitely increased your possibility of developing diabetes. Any fasting numbers above 126 mg/dL indicates you probably already have diabetes.

Dr. Marshall says in the article that even though we’ll have to wait a little bit longer until more research confirms the study’s findings he sees these preliminary results as a red flag. “Having a high normal glucose level at age 60 or older can potentially serve as a useful marker of impending neural degeneration.”

He recommends the Mediterranean diet as one that will help prevent the cognitive decline that often shows up with aging. If you are unfamiliar with the Mediterranean diet here are a few highlights.

To get started with the Mediterranean diet, plan on eating as natural as possible with unprocessed foods such as fruits, whole grains, nuts and vegetables. Cut back on the unhealthy fats and begin using olive oil as your principal source of dietary fat. Begin easing back on the amount of red meat you eat on a monthly basis by substituting it with moderate amounts of fish. Also included in this diet is drinking a moderate amount of wine per day. This means about two glasses day for men and one for women.
