I hear it was one death.
the person was on drugs and was consuming undiluted tamari in great quantities.

I doubt it resembled anything like the modern macro balanced diet.
I think it is far more likely that one would incure health issues from the standard western diet.

of course macrobiotics is powerful and works best when implemented with understanding....

however I would put death way down the list of possible issues!

enjoy your cooking and eating!
