In general I know that our body may accept about 30g of protein in one meal, or every 3 hours.
What happens with slow digestive protein(casein)?
May I use more then 30g protein in one meal and hope that I will accept all of it?
If it is true, how much casein protein I may use before bed time?
Thanks

If it’s “in general”, it’s usually wrong.

Your body can absorb a lot more than 30g of protein in a meal. Maybe if you drink a fast protein like whey, your body won’t be able to absorb all that protein at once.

But when you eat a meal which is usually composed of fats, carbs and fiber, the digestion takes longer and hence the amino acids are gradually released into he blood stream ( in 4-6 hrs). The same goes for casein. It is usually around a workout that you need a fast protein.

So at least from absorbtion point of view “real” foods might be better then some “gidrolizated, super-druper, isolated” proteins?
Interesting…

So I can put more then 30g milk protein before bed time and not be afraid that this protein will be flashed into a toilet?

I remember reading an interesting article by Lyle that suggests milk and whey pwo for a more optimal pwo anabolic environment. Alan Aragon made a post about how whey +casein synergize to cause a remarkable insulin spike (in addition to casein’s ability to prevent IGF-1 denaturation).
However, the presence of casein slows down whey absorption. So, is milk pwo (in addition to bedtime, as anatoly mentioned) a good idea?

and how much whey can you absorb at a time? is the 40g outlined in the study anoop reviewed in his blog (along with the dex and creatine) optimal for both pwo and pre nutrition?

I haven’t really read any of the recent works on post workout nutrition or whey/casein issues. I think there is some emerging evidence to show a mixed protein or a slow might be better post workout and I guess chocolate milk study is a case in point.

The whey protein study looked at protein around workouts and at other times . And maybe the reason why they saw a difference is that whey wasn’t getting absorbed when given outside workout times.

If you are using around 35-45 gms, you are getting plenty enough protein. Let me see if I can look up recent studies on this subject.

hi,
I have a protein shake with milk - the milk slows down the digestion.

When possible I always prefer real food before bed, tuna, chicken, eggs…

What you guys think about this video on casein http://www.youtube.com/user/rickmartis1#p/a/u/2/PxhGBKvS8xE

Hi, i wanted to know since i dont like to eat a lot, but taking in whey protein powder for protein is very easy, so i was wondering how i can take whey protein all the time but make it digest slower during the day when i take it.

You can’t slow down digestion speed of protein you take(I think)
But if you take it all day why you need to be slow digestion in the first place?

Well if you put whey along with some other source of energy you can slow down the digestion and make whey very efficient.
If you compare casein and whey, casein will have a bigger net protein balance, but if you compare them with added energy, whey becomes superior. At least according to this review:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2129150/#__secid588286
go down to “The effect of added energy to fast and slow digesting proteins” under the section “Studies Comparing Slow and Fast Digesting Proteins”

Besides pre/post WO I like to combine protein sources ie. a scoop of whey in milk with some beef.

But it’s not “kosher” at all
