High blood sugar damages the brain
If the looming threat of diabetes isn't enough to get you to keep your blood sugar levels in check, consider this: High glucose means high Alzheimer's risk.
Doesn't matter if you're not diabetic.
Doesn't even matter if you carry a gene known to cause your Alzheimer's risk to skyrocket.
What REALLY matters is blood sugar -- and the higher your levels, the higher your risk of the disease, even if they're just on the high side of normal.
In one new study, researchers looked at brain scans of 124 patients between the ages of 47 and 68. None were diabetic, and all were cognitively normal.
Well, normal for now anyway. Since they all had a family history of Alzheimer's disease, the sad truth is at least some of them could end up with the disease no matter what they do.
But whether they know it or not, too many are doing their best to help make sure they get it -- because the scans found that patients with the highest blood sugar levels had reduced metabolism in key regions of the brain.
That's the same type of damage we see in Alzheimer's patients.
Let me repeat that these patients were not diabetics, so the "highest" blood sugar levels were within the range most docs would consider normal. At the high end of that range, but still within it.
Clearly, there's nothing normal about it -- and along with increasing your risk of dementia and diabetes, elevated blood sugar can also lead to poor health and an increased risk of an early death.
Once upon a time, docs were happy with anything under 110 mg/dl. These days, they're leaning more towards 100 mg/dl.
They're still being far too generous -- keep yours below 90 mg/dl.
