A friend with an unreliable chocolate allergy turned out to have a soy allergy that the soy lecithin triggered (you can find alternatives with sunflower lecithin instead.) Once they figured that out, as far as they were concerned soy was a biohazard :-)

That's interesting. I know I'm fine with soy sauce and tofu. I'll bring it up the next time I'm at the doctor and see what the culprit is.

Seriously, a lot of our developed alergies could just be perfectly natural reactions to the amount of chemicals and other garbage ... everywhere, these days.-
