In the April 2007 issue of Muscle & Body magazine, Dave Hawk’s response to a question concerning soy protein is, to say the least disturbing.? The reader asks, if soy is claimed to be an inferior protein by other authors, why is it used in different products?

Excerpt from Dave’s answer:

What I dislike to hear is the misconception, misinformation and misrepresentation of a great ingredient like soy protein isolate (SPI).? Not only does SPI have natural health benefits, it is 100% equal to whey protein isolate (WPI) in aiding muscle building in men.

Misinformation and misrepresentation, soy protein is garbage.? Obviously Mr. Hawk doesn’t keep up with what’s going on in the supplement or food industries because the FDA denied soy’s heart health claims because of overwhelming evidence to the contrary.

The only misrepresentation is by the soy industry and so called experts who spew their garbage in columns like Muscle Talk.? SPI is extremely low in quality.? The Protein Efficiency ratio, Biological Value, Net Protein Ratio and the Relative Net Protein Ratio, which are all ways scientists rate the quality of protein, consistently score soy protein toward the bottom.

Soy does score high with the Protein Digestibility Corrected Amino Acid Score.? The catch is, soy is set at a score of 100 and 100 is the highest score available.? Because the soy industry flexed their financial muscle, they can now claim their protein is as high a quality as other proteins.? The soy industry spends millions on funding false research and claims in an effort to sell product.?

Dave concludes, WPI is a great staple supplement for anyone’s muscle-building diet, but adding SPI to your daily protein regimen can be a great way to stack your nutritional protein arsenal.

SPI is one of the most highly processed foods one can consume.? Soy beans are regularly treated with heat, alkalis, acids, solvents and oxidizers, in order to make protein products.? Otherwise soy protein would taste like shit and be indigestible.

SPI contains trypsin inhibitors, which inhibits enzymes that help us digest protein.? Supplement wth a protein that inhibits the digestion of protein, smart.

SPI contains goitrogens, which block the synthesis of thyroid hormones.? As soy consumption goes up so does the incidence of thyroid disease.

SPI contains phytoestrogens, which lowers testosterone in men.?

The list goes on, but this is not the forum.?
