Myth? Casein protein slows down whey

[booey]

I think it's a myth, but does casein protein actually slow down the digestion of whey protein when taken together post-workout? If so, I want to know the exact mechanisms behind it. No more parroting!

Im not sure if it does but science would suggest so.
I always avoid milk or anything with slow digestive properties post workout but i def throw it in for a meal shake or before bed type deal - milk / pb / etc.

I like Choc Milk PWO - and have read it is great for PWO.

both casein and whey are fine post-workout. I don't know where Andrew_Plamondon went, but he had a lot of studies posted here showing casein to be optimal over whey. This has also been discussed at bodyrecomp which is Lyle McDonald's board.

The best thing to do is just add in both to cover both sides of the arguement.

Depending on your goals, either caseinate powder, cottage cheese, or milk is fine.

I usually just keep mine whey isolate and water though. I'll use casein preworkout for a more evenly assimilated flux of aminos for during workout.

Yup, good point mang. Ill sometimes sip a casein type protein or bcaa stocked whey before and during my workout with water to keep things fueled up if im in for a rough one.
Same deal with work too. Im on my feet 8-10 hrs a day so i sip somethin with some protein n bcaas in it to make sure im not burnin up and sweatin out what little muscle i have left out in that heat.

Hmmmm, I'm under the impression that whey > casein for PWO - doesn't whey have a greater impact on insulin? Which is what you need post workout (+ fast-acting carbs)... casein also digests slower so it would seem to be better for pre-bed/any other time of the day.

I read a study(I'll see if I can find it this weekend) that reported whey + casein PWO is ideal.

As I remember, one issue with the design of those studies was that they didn't have any protocol for the meal following the post-WO meal, which may explain the results. That is, if people aren't eating soon after (within, say, 2 hours of) their post-WO whey shakes, they may be slipping into a catabolic/hypoglycemic state due to the fast uptake of the protein and carbs. This would, of course, be less of an issue with casein, since the insulin response would be smaller and the meal digested slower overall. So even if casein was less anabolic than whey at first, it may be better overall for preventing catabolism in the absence of a properly timed follow-up meal.

What I'm getting at is that whey may still be superior to (or at least as good as) casein if a reasonable post-post-WO nutrition protocol is followed.

But with all that said, I think the obsession with possible minuscule advantages from fast uptake (see the waxy maize craze), the right balance of whey vs. casein, etc. isn't as important as simply making sure you're eating something with protein and carbs around your workouts, be it a perfectly mixed shake consisting of 45.49598287 grams of casein and 50.4304934 grams of waxy maize and sipped 13:04 before the conclusion of the workout, chocolate milk, whey and dextrose, or whatever.

Chocolate milk is amazing post workout... you're just jealous 'cause you're too anal to drink it.

I think its more myth as well..IMHO ..and judging from my personal experiences and using caseins and whey, your fine dude!

[MR. BMJ]

Cynical, that post pretty much explained my thoughts on the matter too. I always go with whey isolate post-w/o, but I don't have any problems with having milk protein (isolate) and/or caseinate in it as well. And most definately adding another meal sooner after the whey isolate will help like you stated.

I'm at work and can't access those studies anyway. But you are probably right on that the more I seem to remember. They probably have them posted at bodyrecomp though.
