View Full Version : Question RE: Biological values of protein

05-11-2004, 01:32 PM
I've been reading up on the biological values of different proteins. Apparently whey is by far the best, but I was wondering if you could increase the biological values of some less-digestable protein sources by using a supplement like bromelain (pineapple extract digestive enzyme.)

I was also wondering if anyone knew of a site that has biological values of things like nuts and seeds. I've been eatin a lot of this "powerbutter" which is essentially natural peanutbutter with flax oil, flax seed, and pasturized egg whites. I was thinking about making a big batch of something similar, except I'd like to replace the peanuts with sunflower and pumpkin seed kernels, which actually have some nutritional value. If I knew that sunflower and pumpkin kernel protein had as high a BV as peanuts rather lack-luster 40 BV, that would be comforting.

filtration/hydrolyzation affect the values
aminogen affects uptake (according to biased studies)

1) Protein Digestibility Corrected Amino Acid Score (PDCAAS)
2) Protein/Efficiency Ratio(PER)
3) Biological Value (BV)
4) Protein Digestibility %(PD)
WPC_____________________ 1.00___ 3.6___ 104___ 95
Whole Egg________________ 1.00___ 3.8___ 100___ 98
Casein____________________ 1.00___ 2.9___ 77___ 99
Soy Protein Concentrate_____ 0.99___ 2.2___ 74___ 95
Beef______________________ 0.92___ 2.9___ 80___ 98
Wheat Gluten______________ 0.25___ 0.34___ 54___ 91

Thanks for taking the time to reply but that doesn't really answer my question.

I was under the impression that digestability determined bio value, but that table suggests otherwise. That's helpful to know.

did you read all the info on the link I posted? and go to all the links there?
it wont give you values for whole foods, but helps explain more about them.
