Dr. Diane is a classic example of the person who gets a lofty diploma and thinks she has all the answers. They tend to take a little bit of truth and expand it so far that there is no resemblance to the original truth. She presents herself as a neuro-psychologist but her CV shows no training nor residency in neuro-psychology. I find it interesting how she has so many trademarked commercially (profit) oriented endeavors. Most of the neuro-psychologists looking to make a buck beyond clinic oriented diagnostics and therapy, do it by doing sound research and publishing a testing or treatment protocol.

Yes, simple or refined sugars are not ideal. I doubt that they directly impact the brain, but instead, the impact is the rebound effect simple or refined sugars have on blood sugar. The body often reacts by over producing insulin then this excess insulin causes blood sugar levels to crash to very low levels causing a sugar craving and the cycle repeats itself.

These low blood sugar levels are definitely not good for a brain, much less an injured one. In most cases, the blood sugar levels do not get dangerously high like in a diabetic. It is the low blood sugar that starves the brain.

The low blood sugar levels can also stimulate epinephrine which can create an anxiety feeling among other symptoms.

I would be interested in the pub-med article you found. I search pub-med frequently. I am eager to see the articles that are to be released to the public as a result of the recent changes in the copyright protections of studies done with public moneys. The rules now state that such research results must be released to the public without cost 12 months after being published in the professional journals.
