Protein????

Does anyone know how much protein the body can absorb at one sitting? How long should someone take to drink one of those 42g protien drinks to get the full benifit of the protein.
I am pre-op and trying to wrap my brain around all this info now! LOL
Thanks in Advance!

Someone posted on here before saying you couldn't absorb more than 30g at a time.  Don't know the source for that info, though.

Hi Chelie

My nutritionist told me to take in a total of 65 grams of protein per day.  That's either in liquid or other protein like cheese sticks, eggs etc.  Good luck on your journey.

I was told to get 60-80g of protein in daily. I was also told there was no way to get to much--your body doesnt store it and if its not needed your body gets rid of it.

My Nut told me to split the 42 gram tubes into 2 servings. Continually taking in too much protein in a sitting can overload the liver and kidneys and cause gout.  
  I did a little bit of research on this after reading your question this morning, if you take in too much protien, more than the body can absorb, it is stored in the body as fat.  It is my thought that is the main reason our Dr's and Nut's want us to limit our protein intake in one sitting to less than 30 grams, we and they do not want it stored as fat, as we are trying to eliminate the excess fat we are now carrying around, so why add to it.

What I was told by my doctor's office, and read months ago when researching this subject, is that our bodies cannot absorb anymore at one time than 30g of protein, so I try to use that as a guide and usually have two protein 30g shakes a day (1 in the a.m. and 1 in the p.m.), plus consume protein during the day in food for 70-80+g a day.  Probably when I get farther along in this process, I will start replacing one of the protein shakes I drink with more protein rich food.

The 30 g at a time thing is a myth. There is no clinical data to support this and at least one study that refutes it. It also makes no sense when you think about how macronutrients work. Fat, carbs and protein are used by certain systems in the body preferentially and the rest is turned into fuel. If the fuel isn't used, it's stored as fat, but if you are operating at a calorie deficient (as most of us are right now), then it gets used as fuel.

If our body didn't absorb macronutrients over a certain amount, than no one would get fat. We could go out and eat a porterhouse steak for every meal and the excess would just be peed or pooped out.

Here is what the ASMBS says about it:

From "ASMBS Allied Health Nutritional Guidelines for the Surgical Weight
Loss Patient"

"One popular myth is that only 30 g/hr of protein can be absorbed. Although this is commonly found in both lay and some professional literature, there is no scientific basis for this claim."

Here is an article written about it that references a study where they gave people a big blob of protein and measured their nitrogen levels hours later to show that it had all been absorbed. It's also a pretty sensible discussion of protein, how it's used, etc. even if it does come from a body builder.
