References to this article are 15-20 years out of date, with the most recent study in this article quoted as being in 1991.

Some of the points are valid, however it is too biased toward soy protein, which is essential for the vegan/vegetarian that may lack enough protein from other sources of their diet, but not suitable for bodybuilding.

However recent studies have shown that if Soy is not processed properly or at all then it actually works in detriment to a bodybuilder by blocking the absorbtion of nutrients into the body, this was found in a study conducted in 2005 (government funded).

Also it states that Whey Isolate cannot be purchased on its own, this is also untrue, you can buy bulk bags of isolate directly from many, many manufacturers which carry with them FDA certificates, it does of course tatse like cr*p, however these manufacturers will also sweeten AND flavour your purchase to any flavour you like and use a non-aspartame based sweetener to remove the bitter taste.

It states that isolate should only be used directly after a workout or when the body needs protein immediatley (after a period of catabolism i.e breakfast), this is a well known fact and most bodybuilders that have even a small degree of knowledge of basic nutrition should/do know this, which is why they would use a longer lasting protien chain at other times of the day i.e Pro-Peptide, Max Milk or any other micellar casien or casienate.

Plus, and more importantly, if a bodybuilder eats 6-8 meals a day only 2 -3 will be through protein shakes when the body needs protein instantly (as stated above this will be post workout or for breakfast when it is Isolate that is needed) the remaining meals will of course be solids, which are far superior to ANY protien shake if prepared properly.

So I'm sorry Soy protein is not and will not ever be a part of my contest prep, or off season diet and I doubt it has ever featured in Jay Cutler, Ronnie Colemans or any other serious competitors diet.

Leave it for the vegetarians!
