Diabetes 3?
"Some interesting new (as of 2012-13-14) research is showing a link between Alzheimer’s and other degenerative nervous system disorder and the amount of sugar available to the neurons! It turns out that insulin from the pancreas does not cross the blood-brain barrier. Rather, the brain makes its own insulin which enables the neurons to take sugar inside themselves so they can use it. Many researchers now believe that a big portion of what’s going on in Alzheimers, etc., is that, independent of what’s happening in the rest of the body, the neurons are or become resistant to the “message” of the brain insulin: they either are or become insulin resistant (even though the person does NOT have either type 1 or type 2 diabetes), to the point where Alzheimer’s is now also being refered to as “type 3 diabetes!” This has profound effects: if the neurons are insulin-resistant, that means they cannot get glucose inside of themselves. If they cannot get glucose inside of themselves, they starve to death. Interestingly, it has been observed that many people who have Alzheimer’s were huge sugar junkies prior to their diagnosis. That makes a lot of sense: the starving neurons send out the message that they are “hungry” for sugar, triggering the person to crave/eat lots of sugar, BUT that doesn’t do any good because the neurons can’t get the sugar inside of themselves. Thus, the person keeps craving lots of sugar, but “none” of it ever gets to the starving neurons.
This suggests a “simple” way to help “treat” Alzheimer’s and other, similar, neurological disorders: just find an alternative fuel source that the neurons can take in and use, thereby keeping them from “starving.” It turns out, that may actually be a “simple,” easy thing to do!!! Dr. Mary Newport, a UC Med School grad, has accumulated a lot of evidence that the “unusual,” medium-chain-triglyceride (MCT) oils in coconut oil can serve as that badly-needed alternative fuel, helping to keep as many neurons alive for as long as possibl"
