Is all protein created equal? - ThinnerTimes

I sent an email off to the nutritionist in my surgeon's office yesterday. I wanted to ask her about these 3 oz protein vials so many seem to be taking after surgery. I was curious what she thought of them and if it was the kind of protein we should be using after surgery. She quickly got back to me with an explaination about protein. I just thought I would share it with all of you. I know this is a pretty technical explaination but I thought some of you might like to know what kind of protein is best for us when it comes to protein supplements.

Here is her email response:

Not all protein has the same value to your body. The amino acid profile
is the reason for this. Proteins are made of amino acids. There are 20
different ones in the human body. Of the twenty, 9 of them must be
consumed to meet your daily needs. These 9 amino acids are called
Essential (EAA) or Indispensable.

The 9 EAAs are needed in certain proportions. A protein scoring system
called Protein Digestibility Corrected Amino Acid Scoring (or PDCAAS)
was developed to show which products contain all the EAA and in the
correct proportions. It is supported by the FDA, the World Health
Organization, and perhaps most importantly, the Institute of Medicine at
the National Academy of Sciences. The highest possible score is 100.

-- Collagen Protein gets a 0 (the lowest possible score)
-- Whey Protein Isolate gets 100 (the highest possible score)

Some proteins such as COLLAGEN or HYDROLYZED COLLAGEN protein are
missing one of the EAAs entirely. So the PDCAAS for collagen is zero.
Collagen is often the main ingredient in protein supplements that come
in a liquid form, and they usually have lower PDCAAS scores.

Here are some collagen products that have lower PDCAAS scores:

New Whey and Profect1: These products appear to have a PDCAAS score of
5 or 6 out of 100. Lab analyses of several samples suggest that about
94% of their protein, by weight, is from collagen.

Proteinex2: The Proteinex OTC products appear to get protein only from
hydrolyzed collagen, so their PDCAAS score is 0 or virtually 0.

Pro-Stat 64 / Pro-Stat 1013: These products appear to have a PDCAAS
score of about 37 out of 100.

The BEST products to purchase are products made from whey protein
ISOLATE (not concentrate) and soy protein ISOLATE.

Thanks for this information, Beth.. this was exactly what my Nut had told me, but it's good to have a second opinion. I bought the New-Whey protein supplements, and used some of them, but my Nut pretty much went nutty on me about them and begged me, no commanded me to toss them out for exactly the reasons stated in your above post.

I haven't tossed them but I haven't used them again, either.

So is the Syntrax Nectar a whey protein ISOLATE?

Thank you Beth. I was just wondering what type of protien I should buy. This is the information I need. Thanks again

Yes, it is Brenda and according to my nutritionist that is the best choice.

Oh you are most welcome.

I just found it interesting. I had heard talk that those vials may not be the best choice for us so I was curious if that was true. Apparently it is but there are still alot of great supplements out there that would be good for us. Glad you found the information useful.

Thanks very much Beth for the information.

nikkibeat · 05-09-2008, 08:27 AM

Yes, thanks for sharing... my surgeon required that I brought in my protein (and other supplements) 1 week b4 surgery to ensure I will be taking the best things for me. Whey protein isloate (or wpi with no more than 50% soy) is all she would accept. We have very strict "handouts" that were given to us that has all this info in it!

Godsblessedme · 05-09-2008, 03:28 PM

Nikki, i like your surgeon! shes throughough

Beth once again thank you for your great information that is so usefull. In the beginning i had NO clue what protein to buy but since finding out as well that whey protein was best for us

thanks Beth i know your helping lots of protein haters out here

Oh and i just looked at my bottle of special K protein water and there protein is whey protein isolate whew and here i was thinking i was drinking nothing nutritious haa

Great info. Thank you Beth.

I just got some new stuff I ordered online. It's 100% Soy Protein Isolate. It states :
A complete vegetable source protein with a PDCAA score of 1.0, the highest measure of protein quality.

I'm assuming that's the 100 score you were talking about?! (I hope)
