Protein Bioavailability List

I mentioned the bioavailability of protein in my last article entitled "Cook Those Eggs."  It occurred to me, why not post a list regarding the bioavailibilty of common proteins you regularly encounter in everyday life?  It's interesting and useful diet information, that's for sure.


Protein Source
BV
Whey Protein Isolate Blends
Whey Concentrate (Lactalbumin)
Whole Egg
Cow's Milk
Egg White (Albumin)
Fish
Beef
Chicken
Casein (a protein from milk)
Rice
Soy
Wheat
Beans
Peanuts
100-159
104
100
91
88
83
80
79
77
74
59
54
49
43

Just to explain the list slightly, those numbers represent the percentage of protein in each food that can be absorbed by the body.  The top two proteins (whey concentrate and whey isolate) are greater than 100% because they are hydrolized, or "pre-digested" to be absorbed by the body more efficiently than almost any other protein type.  There's a reason protein powder costs so much!

If you're looking for this information, I got it from an article whose Google source I will provide:

    Whey protein contains all the essential amino acids - the building blocks of protein. Since whey protein isolates are hydrolysed, they are more easily digested and therefore the rate of protein synthesis is accelerated. This results in faster muscle tissue repair and thus accelerated development.

    In response to crimple7; there should be NO amino acids or BCAA'S in whey protein. This has been added by the manufacturer to falsify the true protein amount. It's called "spiking". Amino acids should be used or added to other forms of supplements!

      You make no sense. A protein molecule is comprised of amino acids and those include BCAAs..this is what makes up a full protein molecule. If you ingest a 'protein' that has no amino acids then you are not ingesting protein. The term 'spiking' refers to the unnecessary adding of nitrogen increasing compounds to a product. If you're going to post something 3 times at least know what you're talking about.

    Robin, can you clarify your statement? Proteins are made of amino acids.
