Soy vs. Whey proteins.... Question

I have been using Optimum 100% whey protein as a recovery drink, the gym I go to sells soy products only, and state that the whey proteins are "throwaway" proteins. I have felt that the protein that I take is doing well. I would like to start a discussion on your preferences without causing an uproar. I know opinions can be strong. I would just like some facts as they are hard to find searching the internet. It seems to be all opinion there as well. Thanks in advance for any info you all may have.

soy's bioavailability is low, very low. while whey is sometimes over 100% because is has an excess of amino acids that are not natrually occuring. whey will also absorb very quickly after a workout which is crucial. most people will side with whey..
 
Because your gym only sells soy, they're going to push soy and tell you only negatives (perhaps some false) about other options. I highly suggest you don't listen to the salespeople at your gym.

I also use ON and am pleased with it.

I would print these out and non-chalantly leave them laying around. ;) I was only kidding but not really about the previous comment or meet with the director of the fitness center and show these to him or her and ask why they are misleading the customers by only espousing the virtues of soy and not the other side. If nothing else, the customer should at least have knowledge and a choice. And yes, you can bring this up since you are a paying member.

And just for kicks, I went to www.pubmed.com (I actually do that quite a bit anyway) and put in 'search for' the words "soy" and "testosterone" and got quite a bit of stuff. Anyway, here's just one article from there. http://www.ncbi.nlm.nih.gov/entrez/...ve&db=pubmed&dopt=Abstract&list_uids=15735098

Pubmed.com is by far one of the most reputable, progessive, and peer reviewed health sites. This article basically shows that men were given milk protein, low levels of soy protein, and high levels of soy protein and the end result even after 24 hours was that the men who consumed the soy protein had decreased testosterone. Or as they put it " In conclusion, soy protein, regardless of isoflavone content, decreased DHT and DHT/testosterone with minor effects on other hormones, providing evidence for some effects of soy protein on hormones. The relevance of the magnitude of these effects to future prostate cancer risk requires further investigation."
:( :eek:

Seriously, you should bring this to the attention of the director. The mere fact that soy has been linked to increasing the chances for men to get prostate cancer or those that have it to aggrivate the condition is pretty reckless on the part of your gym. Anyway, the info is yours to do with it as you will. Or hey...gimme their number and I'll call them. ;)

Remember, there's always a flip side to everything.

Thanks for the info so far. I think we definately know enough to stick with the whey protein we have been taking. I don't remember if I mentioned that I am trying to control hypothyroid with diet and exersize, but I heard somewhere that soy is no good for underactive thyroid anyway. Thanks again people you are all much appreciated.

Soy is definitely something you should try to avoid if you have thyroid problems.

As an ex-gym customer and now someone who now supplies to gyms, take this to heart: while most trainers/gym employees take supplements, they are not qualified to make recommendations about them. Gyms rarely order new stock and since the cost to them is higher than in a regular retail situation, they tend to treat supplement income as... ... supplemental.

Basically, you did a good thing by consulting us first.
