Question regarding protein shakes breaking down?

[sweetkiki]

Hello, newbie here. I'm trying to find information regarding protein shakes. The controversy is whether or not the protein breaks down if the shakes have not been consumed within 30-60minutes after being mixed. Has anyone ever heard such a thing?
My boss drinks 4-5 protein shakes a day and he mixes them up the night before to let them 'ferment' (so to speak) and let the air settle out of it. He's been doing this for years, and he's in great shape so I find it hard to believe that the protein isn't being absorbed!
I've had gastric bypass surgery so I'm using the shakes as my main source of protein. I've found it easier to drink them if they have been sitting at least for a few hours if not overnight. I'd like to find some sort of article or documentation either way.
Anyone able to point me in the right direction?? Thanks for your help!

How long ago did you have gastric bypass surgery? My Aunt has had this procedure done, so I can call her and ask some info from her on the eating habits that are done after this surgery.

I'm 3 months out and down 40lbs. I've become lactose intolerant since the surgery and have just now been able to start drinking the protein shakes. I'm drinking the Isopure that comes in the glass bottle. I also bought the Isopure Vanilla and am using Lactaid Milk to mix up the shakes. I've only had one of the vanilla and it still doesn't sit well but at least I wasn't nauseous after drinking it. I add S/F Cherry Koolaid to the Isopure Alpine Punch to kill the aftertaste and it makes it tolerable. I belong to another site that is for post-op patients and this issue is being debated. Figured I'd head over to a site that's members really know their protein!!!
Thanks

If you want me to I will contact my Aunt over the weekend and if she still has her internet access up I can get you in contact with her so you have a person to talk with so if she is still on the net I would be more than happy to give you her email address after I speak with her. You two have had the same operation so there would be a lot for you to compare diets and such.

No, I have never heard this. What I do want to know, though, is if I use whey for cooking, ie protein pancakes, does the stuff really denature and become useless?

Peace.

Maybe my good ole friend Mudge can answer this one??? Hey Mudge, where are ya?

Here's Mudges Response...

Creatine cant sit for more than 10m in liquid, dont know about protein (never heard anything).

When cooking the protein it denatures, you can see this in eggs - it unravels into its amino acid componentry, so cook as needed but dont overdo it.

Personally I would consume these products as per the instructions recommendations. Otherwise your always risking not getting the maximum affect of the product.

If mixing in advance and letting it "ferment" causes any breakdown, it will be minimal. Nobody would be able to tell the difference with imperical data. If that works best for you, I say go for it. If you are in doubt, have another scoop of protein during the day. That should make up for any "loss"...if any even occurs in the first place. As for cooking, personally I don't believe you will have any problems here either as long as you don't cook like my ex.(ex-wife that is). lol

BTW, congrats on the 40lbs lost so far.

 

[Randy]

Yeah I would doubt mixing in advance would cause much if any loss. But cooking it I would think it would be more questionable.
But I don't think anyone here know for sure, they're just speculating. You say you would like to find an article or documentation. Perhaps if you write to one of the protein supplement manufacturers they could provide you with the facts.

Thanks all.
I've read that if you are adding protein to something that is heated it is best to add it towards the end of the heating process to minimize the breakdown.
I think I will try and write to one of the manufacturers and see if I can get any info. I did get a nice link today from one of the companies.
Here is is:

It calculates your protein intake requirement and what you are actually getting. I'm not sure if it is skewed downward for absorption by bariatric patients, but it's the first of it's kind that I've actually seen.

We can see that heat could be bad to the building blocks of life for extended periods, but water I dont think so. I have heard, but never read any studies, that say mixing whey and milk was a 'bad' thing, and even that milk protein itself was worthless due to pasteurization and homoginization.

Thanks for the link Sweetkiki.

While the part that indicates how much you need for a body builder is far innacurate, the other one is nice to have .
I'm 6'1 and weigh 225 and it says I need 70 grams of protein.
As you know, you need at least your body weight in grams ideally as a bodybuilder. But that is ok, I already knew that. It was nice of you to share the link with us .

Thanks Mudge for the info

Pasteurisation ruins proteins? WTF. I've been having pasteurised egg whites in cartons for years.

Peace.

Why is mixing whey and milk bad?

I didn't know you aren't suppose to let creatine sit in water for more than ten minutes. Why is that? I usually mix mine with a water and drink it during a workout which takes way longer than ten minutes. I guess I will have to slam that one and grab another for the workout.

 

[sweetkiki]

It's not a question of whether mixing milk and whey is bad. It's whether or not the protein actually breaks down if you mix it say the night before and then drink it the next day. That's the issue. Some say that you should drink the protein drink within 30-60mins of making it. Thanks all!
