Very relative Arizona.
I, for one, find the pronouncements of Linus Pauling on the subject of Vitamin C and it's miraculous curative properties completely IMPLAUSIBLE.
I'm sure MANY studies were done since the stuff was touted as the cure for the common cold and everything else decades ago. It's probable that none showed any results worth touting...or the Vitamin industry would be touting them hot and heavy and even Pfizer would be selling a special patented version of a methylated-DHEA-magnesio-poly-ascorbate complex with Lipitor
for $4 a pill.
Linus Pauling had tunnel vision and saw EVERY disease as SCURVY. His was the perfect case of having one tool, Vitamin C was his hammer, and thus reducing the universe of disease to a nail, scurvy.
I applaud the medical community for letting this dead horse of a theory finally die in pasture as it well deserves.
Of couse anyone who wants to cure "all that ails him" is perfectly free to pump 100 grams a day of intravenous ascorbate or to eat as many Vitamin C tablets he can to the point of inflamed bowel, bladder and stomach. Perhaps the placebo effect will work and he will be cured of all known disease like Linus Pauling was.
(Oh yeah, according to Pauling, it cured AIDS too, which ALSO is really only scurvy!)
