[Guest guest]

It's going to be interesting to see, down the road, the ramifications

of soy found in all these new low carb foods. All seem to have soy

protein isolate as the primary ingredient. Just another opportunity

for the drug companies to counter the effects of all this soy with

some new miracle drug. (maybe they're already working on it!)
