Is protein absorption affected for post workout shake if you use milk or water?

[Pat Bateman]

Just curious as I belive I've read milk is not as good as water. Even if that is the case, is the difference that great?

[Billy Zane]

Good question. I've always wondered too.

[85_305]

Nope. It doens't matter, as all the milk or water is, is a transporter.
Fats only effect the food they are actually *in*. So, in all reality there is no difference between drinking your milk w/ water, milk, juice, etc. Except the fact that milk has some protein, water and juice etc, do not

It does affect it a little, because milk is a casien; however, it's not to the extent that some people make it out to be. So yes, milk slows down the absorption, but it's very little.

^Nope, milk is simply the transporter of the whey. The *milk* will digest slowly, yes, but the whey will digest at the normal rate

wow, thanks for repeating what you just said 2 posts ago. (not trying to start a fight)

^lol, I was just explaining it a little better to 40-Yard Dash_2 a little better

That is the correct answer. It has nothing to do with the fat in milk, casein forms a gel which will delay gastric empyting.

For anyone who cares, look it up at PubMed.

If some of you guys want to read a really good thread about PWO nutrition and the use of milk read this thread. It is by far the best thread ever on bb.com:

Correct. The question, however, is does this matter … Theoretically, you can test for significant differences between two strength athletes with identical genetics, taking the same supplements, having the same workout routine, diet, rest/ sleep etc., the only difference being post wo shake with water/milk … After – let’s say – 3 months, there won’t be SIGNIFICANT – I highly doubt even directional - difference in their gains, looks, whatever you wish to measure …

Preaching to the choir.

I just didn't want the facts to get skewed. I'll let everyone else draw their conclusions. IMHO the best way would be to take whey immediately post-workout, then casein 30-60 minutes later. Other than that I can't speak to how much of a tangible difference would be made, but I'd rather get any benefits, no matter how slight, that way might offer.

I have to disagree with this, the fats part. If you were to add, lets say flax oil to a protein shake, it would slow the gastric emptying process, and the protein, along with whatever else is in there, would make its way to the intestines (where the nutrient absorbtion takes place) more slowly, so therefore if you're using whole milk, the fat that it contains would slow the rate at which the protein is absorbed. Also, as someone else posted, the casein would slow the absorbtion of a whey isolate or concentrate as well, however slightly. Moral of the story, skim milk slows the absorbtion very slightly, 1% milk a little more, 2% even more, and whole milk the most.

That is a very good point, actually. That makes me ponder
Hopefully Loki and Pu12, or even str8flexed will chime in here soon

[BringnIt]

Loki and Layne have already covered this subject thousands of times, casein will slow down gastric empting the most, but fat will also do this. You digest food as a unit, not as individual parts.

[85_305]

^Hm.. I was under the influence that food was digested in parts? As in *additional* parts???

[R_N_S]

no, your stomach is like a blender, mixes everything up, it doesnt pick out each food and digest them at different rates, it mashes it all up, and takes an "average" so to speak


will milk make any difference as opposed to water? who cares, don't make it technical, eat the damn food, lift the damn weight, KISS - keep it simple stupid

[85_305]

^Hmmm.. I talked to a biology teacher a while back, and he was also thinking that the individual foods digest at different given rates compared to everything else...
I dunno; now *I'm* becoming confused

[BringnIt]

Ok, hopefully someone can validate this, but I'll give it a whirl.

Basically, once you eat your food, the food mixes up as forms what is known as a chyme, as ripped said. Your stomach does its thing and food passes to the small intestine. Here the nutrients are digested at different rates, especially fat, which takes the longest to digest. That's why high fat meals are more filling than other foods. So, yes, something like whey at this point would digest quicker than other foods. Casein is unique in that it forms a gel in your stomach which will slow down gastric empyting, delaying the time it would take the whey to get to your small intestine.

Don't accept that as fact, I'm familiar with the general process but I really don't know how individual foods effect it. Hopefully someone with more knowledge will step in.

^Right, that is what I'm trying to say That is what I always thought to be true as well.
