Difference between protein sources

Hey wassup guys I was making this to have an open discussion on the difference between protein sources. For example protein found in peanut butter vs. protein from whey, fish, or chicken. Do they have a noticable affect on body composition?

Reading an article now and wow guys I did NOT know peanut butter is a more easily digested protein than meat and fish. That's crazy!

"Does Protein Quality Matter?

Which brings me to my major commentary about the issue of protein quality: I consider it essentially irrelevant. I noted above that BV, for example, is measured at very low levels of protein intake and this tends to hold true for many of the other methods. Protein quality is measured under conditions of low intake because the primary application of protein quality has to do with ensuring adequate nutrition for people who don’t have enough food. Which means that it stops having much relevance at high intakes.

That is to say, small differences in protein quality make an absolutely massive difference if you’re talking about someone in the third world who is eating small amounts of a single source of poor quality protein and doing so in the context of insufficient total caloric intake in the first place.

In that situation, small improvements in protein quality (by adding other foods or even a specific amino acid) may pay massive dividends in terms of improving health or survival of that group. So would feeding them in general. The World Health Organization (WHO) is very concerned with this issue which is why they make a big deal out of protein quality; it’s relevant to the population that they are worried about.

Anybody reading this article isn’t in that situation for the most part. If you have the Internet and time to visit my site, odds are that finding food in general, or protein in specific, to eat today isn’t your major concern. When people are consuming mixed proteins at the levels seen in the general public (typically 2-3 times the RDA level), and especially among athletes (who often eat more than that), protein quality ceases to become an issue. This is especially true when lots of calories are being eaten.

And while it’s possible that specific proteins might be more or less useful for athletic applications (e.g. providing amino acids specifically needed by those athletes), any athlete eating large amounts of protein will generally be consuming plenty of what they need anyhow.

Athletes tend to get really obsessive about the issue (and of course supplement companies pander to that) but at a protein intake of 1-1.5 grams per pound of lean body mass coming from mixed high quality sources, quality just won’t matter. There is much more discussion of this in The Protein Book.

One possible exception to this is dieting; when calories are restricted, the way the body uses protein can change and different proteins may be specifically beneficial (the dairy proteins whey, casein or simply milk are valuable in this regards for reasons outside the scope of this article).

I suppose if someone in the modern world was eating small amounts of a single source of poor quality protein, quality would matter as well. But that would be some weird self-imposed dietary pattern, not the kind that people in many parts of the world follow because that’s all tha is available.

The bottom line is that, for folks in the modern world, eating fairly large amounts of high quality proteins and lots of calories, quality simply isn’t much of an issue in terms of answering the question what are good sources of protein. Outside of a few weird exceptions, noted above, it simply won’t be relevant.

Next time, I’ll discuss an issue related to this one which is the specific amino acid profile of proteins."

Protein is protein.

 

Difference between protein sources

They contain different types of Amino Acids

 

Difference between protein sources

not going to claim I know much about different amino profiles in protein, but I know that people like AA tend to advocate consuming protein from a wide range of sources to cover all basis.

that is like saying, oil is oil... but fat profiles tend to be very different between different sources

I know the amino acid profiles can be different. If there are any other opinions on protein sources or if anybody has any studies feel free to post; about to look for some myself.

protein is protein, don't matter whether its horse testicles or eggs

You're going to look exactly the same whether you eat peanut butter or horse.

There are a certain number of amino acids ink the world but we only actually require a select few of them to stay alive, and I believe they are abundant in most protein sources.

I think for building muscle though, any amino acids will do, we can always break them down and put them back together differently if need be

Ok let's clarify something; when you say something post scientific evidence to back it up whether it's of your own opinion or someone elses idc but I can have a bunch of kids tell me all day long sh*t don't matter mane; who benefits from that though?
