And it does show how some doctors will hold onto whatever they learned in their initial medical school training and will not update their thought processes even as medical knowledge changes.

The most recent obvious example of this involves stomach ulcers. For many years the conventional medical wisdom was that ulcers came about as a result of stress, too much acid production, or genetic factros. Several theorists posited that they came about from bacterial infection--in fact, said it was almost impossible to get an ulcer without the presence of H. Pylori bacteria--and they were laughed at for years. Lo and behold, a couple of decades of research seems to have proven them correct. (There have been a number of threads on this in the Gluten Sensitivity sectin at Neurotalk and at Braintalk if anyone wants teh particulars.) But it seems as if new knowledge diffuses slowly through the medicla community--and it doesn't reach all corners.

As far as B-12 goes, yes, people with deficiencies need it desperately. But the reason som any of us without obvious deficiencies still take it is due to the neuroprotective effects, especially those of methylcobalamin (which is the form used by the nervous system and a number of other bodily organs). B-12 is absolutely necessary for healthy myelin maintenance and apparently for axonal integrity. And since it's cheap, and safe, there's really no reaon not to take it if one has neural symptoms. (And that's not even considering it has other good effects, such as vascular protection through lowering homocystine levels. Good reason for a diabetic to take it.)

The methylcobalamin form is very important for some who have trouble, due to genetic enzyme problems, converting from cyanocobalamin. Even if one doesn't have this difficulty, methylcobalamin is more readily usable--cyanocobalamin had to be converted to methylcobalamin or one of the other usable forms, and who needs to have a cyanide group floating around?

Much of this, of course, can be found through Rose's website, which is well-documented with medical papers. There are other places, such as up to date medical texbooks, one can also find it. Too bad you can't get some doctors to READ.
