Soy Protein: Is It Good Stuff Or The Devil's Elixer?

[marjon9 6]

Below is a quote from a thread from March 2006. It seems to make sense. Yet many bandsters discuss soy Protein preferences and use it all the time. So, I'm "corn"-fused.

Are people using soy Protein because they don't know the true facts and would switch to whey if only they became Enlightened?

Or:

Are people using soy protein because they know the true facts and disagree that soy protein is bad?

Or:

Some other reason?

If anyone has any definitive information or informed opinions on this topic I would appreciate hearing about it.

Thanks

=================================================

Soy Proteins are vegetable Proteins. The body only absorbs about 30% of the ingested amount. whey proteins are animal proteins and the body absorbs about 80-90% of them.

Quoting the following article on isolates: http://www.bodybuildingforyou.com/he...n-powder-1.htm

"Due to the nature of the ion exchange process, the most valuable and health-promoting components are selectively depeleted. Though the protein content is increased, many of the most important subractions are lost or greatly reduced."

So, you can see why soy isolates would have even fewer benefits. You are basically paying a lot for a whole lot of nothing.. except gas pains.

This is an excerpt from a NESTA certified training manual for personal trainer certification:

"Although considered complete proteins, the human body does not possess the necessary enzymes to break down vegetable proteins and most of it ends up in the colon where bacteria gain access to it. Research has shown that most of the gas once thought to come from the Fiber found in vegetarian sources of protein such as Beans, is now known to be caused by the undigested vegetable protein instead."
