So What is Soy Protein Isolate Safe For?
When the Federation of American Societies for Experimental Biology
(FASEB) undertook the evaluation of the health aspects of soy protein
isolates as feed ingredients, they found that the only safe use for
them were as cardboard packaging sealers. The preamble to the
evaluation (SCOGS-101) said:
"The Federation of American Societies for Experimental Biology
recognises that the safety of GRAS substances is of National
significance, and the Federation resources are particularly suited to
marshalling the opinions of knowledgeable scientists....
...These scientists were chosen for their experience and judgement
with due consideration for balance and breadth."
With all that breadth, they decided that the only satisfactory use
for soy protein was as a cardboard sealer, and that was because not
enough carcinogen would leach into the contents to pose a health
hazard.
In those days, per capita consumption was stated to be less than one
third of a gram per person per day, and even at that level, soy protein
by clear implication posed a health hazard.
