I just thought I'd post this here for anyone who may be interested. This is a copy and paste of an email that I recieved from Unjury today.

Important New Protein Quality Guidelines from Surgeons If you have been reading our updates, you know we have regularly advised that: - whey protein ISOLATE is better than whey protein concentrate- collagen-based products such as the test tube products get very low protein quality scores. Profect and New-Whey are calculated to have a PDCAAS of 5 or 6 out of a possible 100. (1)
Historically, we have perhaps been the only ones saying this. Now the bariatric surgeons, dietitians, and nurses have just issued Protein Quality Guidelines, and everything they recommend is consistent with what we have said. While many many products do not meet the guidelines, you should know that for every single new guideline, UNJURY matches it 100%, fully, completely, exactly, and it always has. While the full set of guidelines should become available on the web soon, here are some of the key messages from the guidelines. (2).
1. It’s not enough to know how much protein you are getting (how many grams). You also have to look at the amino acid profile to know about the QUALITY of the protein. (Some proteins have almost zero value.)
2. The PDCAAS scoring is the superior way to rate protein quality (it looks at the levels of each indispensable amino acid).
3. Doctors, nurses and dietitians are advised to use Caution when recommending any type of collagen-based protein supplement (for example, the “test tube” products). So you too should use Caution when using products with hydrolyzed collagen.
4. Whey protein ISOLATE is better than whey protein concentrate. (Concentrate has more lactose, and gives you less protein.)
5. Recommended daily grams of (high quality) protein: 70 grams per day during weight loss and low calorie diets. The society issuing the guidelines is the American Society for Metabolic and Bariatric Surgery (ASMBS), and almost certainly your surgeon, dietitian and nurse are members.
The guidelines were announced Monday June 16, 2008 at the ASMBS annual meeting. You can be sure that most of the products, those which don’t fully meet the guidelines,will try to make it sound like they do, or will try to say that the guidelines are not important. But here are 2 easy rules to remember:
1: “Caution on Collagen” (e.g. about 94% of the protein in the test tubes is collagen)
2: Whey Protein ISOLATE is better than Whey Protein Concentrate Here are three key messages from the guidelines:
A. “The PDCAAS score indicates the overall quality of a protein.”
B. “The PDCAAS score indicates the body’s ability to use that product for protein synthesis.” (Protein synthesis is necessary for making every cell in your body.)
C. You can lose lean body mass (for example muscle and organsincluding the heart) even if you get the right number of grams of protein, if the protein doesn’t have each and every Indispensable Amino Acid IN THE RIGHT AMOUNT. In other words, even if you used 3 of the “test tubes” every day, you can still lose muscle and organ tissue because the test tubes have a deficiency in indispensable amino acids. (1)
We hope this is helpful. If you have any questions, please do ask us. This is too important to your health.
Healthy regards

(1.) We calculated the PDCAAS (amino acid scores) of Profect and New-Whey based on assays of samples we sent to Covance, Inc, a leading independent laboratory, in 2007. To our knowledge, they have never disagreed with our calculation of their PDCAAS scores.
