Shaklee has known how to separate soy with cold water extraction since the early 1950's. Dr. Shaklee was one of the earliest researchers in soy in the USA. The effects of soy was first measured in birds which showed they changed foliage and matured very young as well as slowing down the thyroid function.
After this observation they realized there was an anti-tyrosine property in raw soy beans. So Dr. Shaklee had to separate the protein from the raw soy bean and leave behind the enzymes that contained the anti-tyrosine substance.
Another problem is when you cook soy, in order to de-nature compounds like the anti-thyroid substance, then you begin to rearrange the amino acid substance in soy which then becomes a toxic substance. Two years ago, Vegetarian Times ran an article telling their customers not to eat soy products because they are poison.
Shaklee has known this for a long time. There is a process called a "Mallard" reaction - whenever you cook a food you de-nature it and make it into something different. That's why the Chinese would take tofu, which is a water extract of soy curd, and cook it and eat it right away, before there was any time for degradation. There is no word in the Chinese language for hot flashes because they don't cook things and store them to eat them later, especially soy,
Dr. Shaklee knew that, too. By using a cold water extraction technique, you get the very best of the soy and all of the positive things like the phyto-estrogens which inhibit breast cancer and prostate cancer in men. There are over 1500 studies showing the positive benefits of soy and only 12 to 20 negative studies showing that when you alter and de-nature soy you end up with junk. Dr. Shaklee knew the difference.
Some people today don't read the fine print to realize there is a difference in soy. The Veggie burger group and several other companies' textured vegetable protein products produce cancer, we know that.
The difference in Shaklee is that they did the research long before people even started talking about this stuff. You can go on the net and get an article written by Christopher Jensen, PhD, MPH, School of Public Health, University of California, at Berkeley, about the anti-thyroid effects of soy.
