The last 10 years of my mother's life she seemed to live on ice cream, cookies and other high-carb foods. What did that do to her brain? What has the low-fat, high-carb American diet of the past 20 years done to all of our brains?One of the things I care most strongly about as a dementia caregiver advocate is encouraging caregivers to do what they can to reduce their own risk of dementia. I know it often feels as if we are too busy to even go to the doctor for ourselves, but it's important to be aware of what can increase our own risk of developing Alzheimer's disease or another common dementia such as vascular dementia from small strokes.
Did you know that 50% of Americans are either diabetic or pre-diabetic (that is, with blood sugar on the high end of normal), putting them at much higher risk for cancer, heart attacks, stroke and dementia? 50%!! According to the research I did for my book, someone like me who is pre-diabetic is 70% more likely than someone with normal blood sugar and insulin levels to develop Alzheimer’s disease.
But most of us who are pre-diabetic never get a diagnosis. I am convinced that the rising epidemic of diabetes and pre-diabetes is directly related to the dementia epidemic. (In fact, Alzheimer's disease has been called "Type III Diabetes.") Of course there are probably many other causes, and there is no proven way to prevent Alzheimer's disease or other dementias. But that does not mean that we are powerless.
Here is what I do to lower my blood sugar and risk of developing Alzheimer's disease and vascular dementia: I try to eat Paleo (protein, healthy fats and lots of veggies--very few carbs). I am active in a 12-step program for those who eat certain foods compulsively (I am a sugar addict). And I exercise regularly, including weight training twice a week, which has been shown in research studies to slow cognitive decline in people with mild cognitive impairment. I've lost 50 pounds but have another 50 to go.
One sign of being pre-diabetic (also called having "insulin resistance") is having extra weight around your middle. If you have a belly at all, ask your doctor for a blood sugar test. And if she seems unconcerned that your numbers are high--because you don't yet have full-blown diabetes--don't let her complacency fool you into thinking you're not at risk. You are. Especially if you have belly fat in middle age. Keep your blood sugar (and accompanying insulin levels) down and you can help protect your brain from unnecessary damage.
