Whey Protein Powder.

[xxsicknessxx]

I mix mine with water just seems like it would absorb better then milk to me. I drink lots of milk too. I take care of my self now days. I drink at least 9 gallons of milk a week whole! and I drink two cups of 20g protein a day.

Note. Try to take in 20g of protein at a time you body has a limit of what it can absorb at once. So I am told.

You (and others) have been told incorrectly:

There is no maximum amount of protein that can be absorbed at one time. Protein is broken down into amino acids (AAs), which get stored for a finite time. When your body needs an AA, it will pull it from storage. If your body doesn't need an AA, I don't know if it gets excreated unused or if it gets turned into something else--Either way, all the protein from your meal had been "absorbed", so to speak. There isn't protein traveling through your digestive tract whole, even if you eat 60 grams of it at once.

My source is a nutrition professor who is teaching according to what the American Dietetics Association says. Quite possibly she's/they're wrong though--Who told you (this goes for any of you) that there is a cap on the amount of protein you are able to absorb at once?

although you could absorb much more, there is only so much that can be really useful in a day. perhaps this is where the wires cross in advice.

Wait.. why are you quoting yourself?

Anyway, I won't even get into who your professor is, their accreditation, how long ago they learned what they're still regurgitating to class after class, etc.

Let's be reasonable, because I'm not looking up any citations:

Milk versus water - they aren't going to affect protein absorption significantly. The post insisting that milk proteins have a low availability can cite that, or we can drop it. Milks don't vary that much, mammal to mammal. How do babies survive without formula?

Your body can effectively handle a reasonable amount of protein; it certainly doesn't top out at 20g. I think the post about 'how much your body can actually use at one time' is one of the most relevant.

Which leads me to explain the snarky intro about your professor. Your logic conveniently drops off right after the point of interest. I don't know if it's your fault or the professor's, but let me clarify. Amino acids are not stored. Amino acids are not excreted, unused. Your body can never 'pull' an amino acid out of storage, even in a catabolic state. Amino acids are utilized to the extent the body deems necessary, based on genetics. The rest is converted into the fundamental currency of metabolic energy: glucose.

Most choose to err on the side of caution, which, in the case of muscle growth, means excess consumption of protein. This can be taxing on your liver but if your lifestyle habits reflect that of someone trying to improve their body, this alone will not debilitate your liver.

The '1g/lb/day' rule is bullshit, too. There is a lot of misinformation on the internet; don't take my word or anyone else's. Get familiar with textbooks and academic journals. Broscience is the polio of our generation.

would it be advisable to drink protein powder if im not working out? i haven't put on weight or mass in forever and i tihnk its due to me not getting enough protein / having a balanced diet. i do physical work for a living.

should i take protein or just try to have a more balanced diet?

I quoted myself because people seemed to miss it when I first said it.

I was not aware that excess amino acids were turned into glucose--I thought they were stored... somehow. You're right though, that that chapter was indeed glanced over as that's "not really our field." 8)

Actually, while your liver does filter toxins, the excess protein would be more of a stress to your kidneys as they filter your blood.

You're right that people need to quit listening to "broscience"--Never heard it put that way, but yeah. People need to stop listening to their bro, or the Internet, or somebody in a magazine. There is a huge difference between a magazine and a journal. Sure, you may get some reputable information from a magazine, but most likely not.

My source is my doctor who preformed gastric bypass on me (now maybe he was talking about people with the surgery) but he said and i Quote people can only absorb 20-30gram of protein at any time. His specialty is the stomach so I kinda believe him but again maybe just maybe he means people with my type of surgary though he said everyone at the time but I do get things wrong.

The doc is a moron, to put it bluntly.


As for the OP: It really doesn't matter. You need to rely more on whole food sources and only use the whey post-workout or whenever you can't get a decent meal in. Use whole milk and mix oats and peanut butter into them for extra calories.

My tub of whey protein powder says mix with milk, juice or water. I usually mix it up in my blender with milk but I'm not sure if this is the best way to take it for the human digestive system to digest all the protein. As far as I know when a human drinks cow's milk a lot of the protein is missed because we can only digest a small amount of the nutrients in cow's milk. Taste wise I quite like the taste of it mixed with milk but I was wondering if it's better to mix it up with water instead? Any info would be great. Cheers...

The protein digestibility corrected amino acid score of both whey and casein is 1, meaning they're easily digested and absorbed and contain a balanced amino acid profile. You shouldn't have any trouble digesting a reasonable amount of either. Some people are sensitive to casein, but overall casein isn't nearly as bad as e.g. gluten or peanuts. While I've heard suggestions that casein may damage the intestinal lining like gluten, I've never seen any real evidence.

If milk gives you digestive problems my money is on the sugar (lactose et al). Casein sensitivity usually manifests as an allergic reaction, e.g. congestion, itching, swelling; it doesn't show up as a digestive issue.

[re: gaining weight]

The easiest thing to do is just eat more food. Protein is not special in this case, and since it makes you feel full too much may be counterproductive.

My source is my doctor who preformed gastric bypass on me (now maybe he was talking about people with the surgery) but he said and i Quote people can only absorb 20-30gram of protein at any time.

Probably because you've had a gastric bypass! If you still have a stomach, any excess protein should remain until it can be digested. If you have no stomach, that isn't going to work.

I personally have heard recently (The Primal Blueprint by Mark Sisson and Mark's Daily Apple) that yes, humans can only digest 20-30 grams of protein, but this is each hour. Since our bodies can continuously digest, that would mean a continuous 20 grams of protein every hour.

I tried whey protein powder when I was younger to try to gain weight. I also ate a lot of protein as well and it did not do anything. I would mix it with milk and it tasted pretty good but it was chocolate flavored.
