Protein Bioavailability Chart

[HDH]

I thought this chart was pretty cool, I haven't seen one in a while. I saw it in an article I was reading the other day, it's just a c&p from that article.


It can make us think about how much protein we are actually getting. I really don't pay much attention to the bottom half as there are no aminos. I was trying to explain it the other day to a younger fella so I just told him if you can't kill it, or drink it from a tit, you don't want it

Of course, you can mix powder as well.

Thanks, I definitely need to try, finally a legit source!!!

Nice post HDH

and yes Jin, Cambodian chicks are smoke shows. Put em in a pretzel and destroy.

Anyone know anything about the wheys being above 100%.

I'm guessing it has to do with the bodies ability to utilize it.

interesting. good post. only powder i use is iso as i like to eat my food but use the powder right when i leave. just use the Walmart brand and damn for some reason..i love the taste with water.

 

[gymrat827]

if i was going to guess.......Id be way off on 80% of them.

interesting

Might all just be relative to Whole Egg but that’s just a guess. I think Zilla would point out we don’t have a source. (Oh well, we’re amateurs)

not to sure about the whey concentrate being 104

I've got it up on a few boards, I'm going to ask the question on all of them.

All you need to do is say “RippedZilla”, bro.

 

[DevilDoc87]

I think you have to say it three times Jin.. at least that’s how it works in the movies

Ya, he was my next move

I did get this from Mike_RN over at TID-

The egg is the bench mark for bioavailability. Hence the 100 rating. So refined proteins like whey can be above 100% because the figure is comparing every other specimen to egg. Its like the Anabolic/Androgenic ratios we all love. Test is 100:100 and every derivative is measured against it.

 

[Seeker]

one thing to take into consideration is that with whey, manufacturing practices will lower the bioavailability. Not taking away whey as a good source of protein, because it is. But manufacturing will definitely lower it. Some more than others.

I would agree with that along with Biochemical Individuality and each persons ability to process it.

That would also account for ISO showing 100 to 159.

If this is supposed to be biological value (BV) then no protein source has a score of a 100. Never mind above that.
Did the original article actually cite a source for this information? Or did they just regurgitate from someone else? Or did they just severely misinterpret 1 specific paper that doesn't come to mind right now? My guess will be the latter. You can't take in 1g of protein and somehow end up storing 1.4g - that isn't how this shit works.

BV is determined under conditions of very low protein intake. Lower than the general norm & certainly lower than what we consume. This is done because BV is adaptable. It goes up in a caloric surplus. It goes down in a caloric deficit, which is one of many reasons why you need more protein dieting vs bulking. It goes down when total protein intake is bumped up. Sex matters. Etc. Etc.
So even if those numbers were accurate, which they are NOT, they would still mean jackshit in the grand scheme of things

Thanks man, I will post this at the other places as well.

That is actually on several charts.

The only charts that don't that I have seen only show whey, not iso or concentrate.

Also, all charts, even studies show eggs as 100%.
