Is there Soy Isolate Protein in soy milk?

[marybeth0051]

I recently heard that soy isolate protein is not good for a person and can promote tumor growth. I make my own soy milk from beans. Would this have soy isolate protein??...or is it only in processed soy foods??

Homemade soy milk (that is made from beans that you cook, puree and strain) does NOT contain isolated soy protein. However, it does contain naturally occurring soy protein that has never been separated from the soy beans.

Isolated soy protein is just like its names says -- ONLY the protein isolated or removed from the soy bean and NOTHING else. Home made soy milk contains naturally occurring carbs, protein, fat, vitamins, minerals, antioxidants, phytochemicals, etc. -- and NONE of these have been sepatated from the beans and then mixed back together to make soy milk.

BUT you should be aware that isolated soy protein (and sometimes "free" oil) is in some brands of soy milk -- but NOT in all. Just read the labels very carefully if you purchase any ready-made soy milk.

thanks for the info!!...sounds like sticking to unprocessed foods is the healthiest thing to do.

The milk thing was new to me. I was browsing the list of approved foods. And was suprised when the WestSoy Non-fat milk was not on the list. The low fat is on the list - but not the non-fat. At first I thought this was an error. And then I looked at the label. It has isolated soy protein in it. Uggh - now I have to find us a different milk sub.

So I was trying to cheap out by buying the low fat vegan mayo at Trader Joe's - turns out it also has isolated soy protein in it. So I'll have to stick to nayonaise.

The funny thing is that I wasn't a big milk or mayo person before McDougalling - but there's always some recipe where there isn't really another good sub. So I keep these things on hand.
