Extra in protein



Recommended Posts

Does anyone add an extra scoop to bottled Protein Shakes? Instead of having your typical 30g of Protein per bottle your getting 60g with that extra scoop. Just checking to see if I'm the only one; Hopefully not.

From what i understand we can only absorb 30 grams at a time. now, unless you are spreading that shake out over a few hours then you are ok . otherwise, you might just be wasting Protein Powder.< /p>

If you drink that over time you're okay, if no, you are wasting it:( like it was said we only absorb 30g at a time.

I was double scooping to get all my Protein at once and my doctor informed me of the error in my ways.

Good luck

This is only the case with man made Protein powders. If you are ingesting natural protein you are able to absorb more than 30g at a time.

Does anyone have links or literature to this theory that we only absorb 30g per sitting. Not that I don't believe but I'm a skeptical person and I require hard proof to believe anything.

I've read a few articles online and came across this one, as it was the most intriguing. One can only speculate its truthfulness or not but sounds pretty convincing.

Although I have often read on the forum where any number of doctors have stated the 30g Protein serving limit, I have never been able to find any high confidence research that either supports that or disputes it. I suspect that coming up with a good rule of thumb on Protein is a daunting task because there are so many variables not only in the type of protein, but in the digestion/absorption rates and a whole host of other things.

M.A. Cruz, I found the article you linked to be interesting and quite well written. The author's description of the digestive process of protein was particularly interesting. But we have to remember that the author's intended audience was not RnY patients. The pre-digestion process in the stomach and digestion times in his article must be considered suspect. We have limited pre-digestion taking place since the stomach is out of the picture. food passes much more quickly from the pouch into the intestine than it does from the stomach (with the pylorus) into the intestine. We also have to remember that some portion of the duodenum is bypassed - how much will vary by patient and by surgeon so that can be a difficult factor to estimate.

Then when you attempt to factor in differences in digestion/absorption rates for different protein types, it gets even more difficult. Filtering creates higher amounts of protein for a given volume - think whey concentrate vs. whey isolate. But denaturing protein, using heat or acid or both, changes the protein on the molecular level. Denaturing effectively reduces the size of protein molecules which results in protein being absorbed into the bloodstream substantially more quickly and therefor presumably in higher amounts. Hydrolyzed protein is absorbed even faster still. And it goes on and on.

One word of caution, there is evidence that too much protein in your diet can result in some potentially serious problems. The research is not yet conclusive but the Institute of Medicine's Dietary Reference Intakes suggests that doubling the amount of protein can result in a 50% increase in the loss of Calcium through the urine. And may increase the risk of kidney stones by 250%.

From what I've read, you may want to carefully weigh any potential benefit of that second scoop of Protein Powder against the potential risks that may be associated. Science does yet seem to have a definitive answer to both sides of the question. It might be wise to err on the conservative side of things until more is known.

Here's a link to one article in WebMD that discusses some of these things in more detail -
