No matter what board I go to, I see a ton of basic questions on protein and the answers given are often completely ludicrous and sometimes get me laughing out loud.
One common misconception is that whey isolate is superior to whey concentrate. All whey protein is basically the same. Whey isolate is just whey concentrate that has had the whey protein isolated and all by-products and additives, etc. disposed of. The actual protein quality, biological value, and absorption rate is EXACTLY the same, only you get a fraction more whey protein per scoop, as there is nothing but whey in there. This confusion is due to dishonest marketing hype...plain and simple!
Whey hydrosylate is the fastest absorbing of the 3, but it is simply due to cutting the protein into smaller strands (not being technical here, so no corrections, please) Actual muscle building quality of the whey remains unchanged. Some people actually prefer whey protein concentrate as it contains more of biologically active peptides (eg., lactoferrin, alpha lactalbumin, immunoglobins, beta lactoglobin and so on), that have various health, weight loss, and muscle building properties attributed to them. These subfractions are mostly destroyed in processing and "isolating" the whey. The biggest advantage for many is the lack of stomach discomfort and bloating that comes with WPC. The only instance where the higher cost of isolate is warranted is if a person is lactose intolerant.
Milk protein isolate and it's cousin casein have a lower bv than whey, but most current research shows these will build muscle better than any form of whey. Beverly says to achieve the most anabolic protein shake possible, combine 2 scoops of hydrolyzed whey with 1 scoop 100% egg, while Berardi at T-Mag says a 50/50 blend whey/casein is the most potent blend. Regardless of which theory is most correct, it is apparent that the top protein gurus feel whey either needs a more complete amino profile or needs to have the absorption slow down a bit (or both) to be at its best.
And whole eggs are the single most anabolic protein on the planet. No protein powder comes close!
Whole egg is still the gold standard having a bv of 100. Nothing can go above 100, and no whey protein can come close to being as anabolic as whole egg protein.
Supp companies go as high as 145 for whey protein isolate. If you believe this, you probably believe Lee Priest got his build from using Cell-Tech and Hydroxycut. And of course, there it is in print, "Build muscle and lose weight at the same time with Methoxy 7. It's a fact! And our new formula is twice as potent gram for gram."
Another fallacy is that soy protein produces estrogen. It doesn't. It contains phytoestrogen. This is a good thing, as phytoestrogens will bind to estrogen receptors as opposed to estrogens. The estrogen thing is neat because a phytoestrogen has weak estrogenic activity. This sounds bad, but if someone has high estrogen, i.e. you're fat and have boobs (and you're not female), the soy estrogen will bind to your estrogen receptor sites and BLOCK your endogenous estrogen from binding to the sites. This is good because you're blocking a much more powerful estrogen with a much weaker one, reducing the harm of high estrogen.
I wouldn't use soy as my only source of protein, but then again, I wouldn't use any one single protein as my only source of protein. If I was forced to choose one source of protein as my only source of protein, it would be egg protein. Soy protein has overall cardio-protective, leaning, and anti-cholesterol effects. Remember, Sergio and Arnold used Soy and casein proteins as whey wasn't available back then.
