The following is an exerpt from a recent article written by Lee Labrada. This surprised me when I read it. I know, its another long post by me, but I think you'll enjoy this.....
-----
Picture this: You put all of your hard-earned supplement dollars into a nice little mound on your kitchen table. You divide it in two, and pocket half. Then, you pull out a lighter and torch the rest of the money! Sound crazy?
If you are relying on whey protein for your primary protein supplement, you may be burning more than half of your hard-earned supplement dollars, not to mention sacrificing your precious muscle! That may not be what you want to hear, but you deserve straight talk, and that's what you can expect from me, Lee Labrada.
.....You see, whey protein, like all other proteins, is broken down in the stomach into short protein chains called peptides, before being passed into the small intestine, where the peptides are absorbed. Whey protein is broken down very quickly, flooding your body with nitrogen-rich amino acids. That's exactly what you want if you have just finished working out and need fast muscle support to jump-start recovery. But at other times, like meal time or snack time, for instance, you are best served with a high-quality protein blend. Here's why:
Your body can only use so much of the amino acid "surge" that follows the ingestion of whey. Once your body uses the whey amino acids it needs immediately, the unused portion is shuttled to the liver where it is converted to blood sugar by a process called gluconeogenesis. As much as 58% of whey is unused; there goes more than half of your protein supplement dollars!
There's more. Because you're getting a big shot of amino acids "up front," there may be no amino acids left over to nourish your muscles and keep you in positive nitrogen balance in the hours leading up to your next meal! Whey protein only lasts about 90 minutes in your system - which means that after your muscles get their initial "fill" of amino acids, you could go catabolic in the hours that follow. Catabolism, or muscle breakdown, may occur when there is an insufficient amino acid supply available.
There's little else that will cause muscle wasting faster than a lack of amino acids. It's like putting a match to dry wood! Poof! Gone. All of your hard work in the gym is for nothing. What you need then, is a protein source that is broken down and absorbed slowly. This type of protein source should provide amino acids to your muscles for hours, so that your muscles don't starve in between meals! That's important so that you don't sacrifice your hard-earned muscle!
Recently, some manufacturers have started adding glycerine to whey protein, claiming to slow down its absorption for hours, yielding a "time released" protein. If that is true, then you can make the same claim for many protein bars! Popular protein bars typically contain several times the amount of glycerine found in a serving of these latest-fad whey powders.
The fact is that a protein blend consisting of multiple sources of protein is superior to any single-protein source, including whey, for sustained, "time released" nutritional support. A protein blend can provide a "staggered uptake," as the different proteins that comprise the blend are broken down and absorbed at different rates.
High-quality milk protein isolates and casein are superior to whey in that they are absorbed more slowly, while providing benefits that whey itself cannot provide. In my personal experience, nothing beats a good meal replacement powder (MRP) for sustained nutritional support for muscle.
Just as an aside, at least two major supplement companies have truly missed the boat by developing "MRPs" containing whey protein as their only protein source. In the typical "me-too" fashion of the sports supplement industry, these companies blindly jumped on the whey protein bandwagon without a thought to the application for which people want an MRP in the first place: a high-protein meal that provides sustained nutritional support."

I don't know the answer but I did read the article. So basically they are saying that protein shakes are really on good and that we shouldn't have it more than once a day? I use it for breakfast and as a post workout shake. Are they basically telling me that I shouldn't have it for breakfast because it will only starve my body until my lunch?

So what is exactly "new" about this article? I thought that was pretty common bodybuilding knowledge. For immediately post training, you want a pure whey for its fast absorbancy. But after that, you want to slow things down. A good "blend" protein the rest of the day is then advisable. Hydrolosates and beef blend along with casien are a very good blend. Thus, the difference in quality proteins.

So what about to meet my daily protein consumption if I take some whey with some milk. Would this work or do I need to go with a Meal replacment shake?

As the day goes on, MRP's really have their place. If you get a quality one, it will have a good blend of proteins. You are right in your assumption that milk will help, it does slow down the digestion somewhat. Adding egg protein to it another good way to slow down the digestion, and one teaspoon of flax oil is very good. This is the trick as the day goes on, so your body will get an "even" flow of protein to try to stay in a positive nitrogen balance. Pure whey is absorbed way(no pun intended) too fast. I really don't like to advertise any companies products on here, if you want to email me I can give you what I think is the best by far. I have spent lots of money finding these things out, and I may be able to save you some. Good luck.

The part about the MRPs did not surprise me at all. It was the fact that whey gets digested so quickly by the body - almost too quickly. After the part about gluconeogenesis, there rest is common sense.
I posted this article mainly for those who take whey protein as their main source of protein. I only take whey after I workout and early in the morning after I wake up on my recovery days. From some of the posts I've read on here, it sounds as if some people misinterpret the information they read and are relying on whey as if its the only good source of protein out there.

jbennett...are you ever so right about some people on here "misinterpeting", to put it mildly. I have read some rather "interesting" responses to questions asked on here. You sound like you have done some homework.

Wow guys, this totally changes my perspective on how I should take whey protein. I mean I've used it as a common breakfast sometimes. And now this new information (at least to me) has come forth and I really need to rethink my habit of eating. Now I have to add in more "real" foods which contain protein in order to replace/supplement where I had shakes before.
I must admit, thanks JBennett for pointing this new info out to me as I think I would've continued my whey eating days. So now people say Meal replacements are a good way of using protein shakes as opposed to the regular whey protein. Hmm..that might be an idea tho!
