Thank you!
This is actually not-too-dissimilar to the story of scurvy in European navies in a more distant time. It took a lot of lives and most attempts to alleviate it were based on the totally false theory of humors.
Doctors can be very resistant to change of paradigma. I wonder what is our scurvy or beri-beri; given how fat and diabetic the developed world has grown, maybe nutrition.
