Excellent point.
Soy should be avoided.
My suggestion re never eat processed foods would probably eliminate 99.99% of the soy.
I am one of those people that spends far too much time in the store reading labels, and you are spot on. Soy is in EVERYTHING that is processed. Do you know how hard it is to simply buy a loaf of bread that doesn't have soybean squeezin's in it? I mean... EVERYTHING has it.
I am surprised that bottled water doesn't have it... though they probably spray it on the injection molds that form the plastic bottles the water comes in.
Also, file under truth in advertising: "AUTOLYZED YEAST EXTRACT"... this is the way they (with FDA approval) get around the MSG label... I see products that say "CONTAINS NO ADDED MSG"... but the ingredient list has the rather innocuous "yeast extract" ingredient.
"Autolyzed yeast extract" is essentially MSG.
