An Article entitled Does Sugar Cause Dementia caught my attention.

It is based upon a recent study in Neurology which concluded: 

High plasma glucose levels within the normal range (<6.1 mmol/L) were associated with greater atrophy of structures relevant to aging and neurodegenerative processes, the hippocampus and amygdala. These findings suggest that even in the subclinical range and in the absence of diabetes, monitoring and management of plasma glucose levels could have an impact on cerebral health. If replicated, this finding may contribute to a reevaluation of the concept of normal blood glucose levels and the definition of diabetes.

This highlights the possibility that Insulin Resistance may significantly impact neurological functioning. 

“Once people become insulin resistant, they start to develop microvessel disease, the leading cause of dementia,” reports Bradley Bale, MD, medical director of the Heart Health Program at Grace Clinic in Lubbock, Texas. “Small blood vessels become damaged, reducing the amount of oxygen and other nutrients that flow to the brain.”

We have already been told that the older brain can not utilize glucose effectively and can be aided by a switch to Ketone based energy source.  Axona, MCT oil and Coconut Oil all produce a high level of Ketones even in the presence of carbohydrates.  That is why individuals with Alzheimer’s Disease and dementia along with other neurologic disorders utilize them.  Similarly, a Ketogenic diet will switch the entire body to a Ketone based system.  BUT – this is an after-the-fact treatment – not a prevention.

Now we are starting to see that eating in a manner which will prevent Insulin Resistance or reduce its impact may prevent or lesson the eventual deterioration of our Brains.

Hold the bread and pass the veggies – I’ve got some thinking to do.
