I actually think the ratio is the most important. The problem is I don't think anyone really knows the perfect ratio and the ratios are probably a bit different for everyone.
I definitely agree with Potter here about the ratios being more important than the total amino sum. His point about what's healthiest vs. what makes you grow fastest is another good point.
It's pretty common knowledge around here that it's healthiest to eat a wide variety of foods, so in the past I have applied this to my protein supplementation. Using a bunch of different types of protein (soy,rice,hemp,pea,etc.) may not yield an amino profile similar to whey isolate, but I always reasoned that getting protein from a bunch of different sources is probably more healthy that getting it from just one or two.
But getting back to the whole amino acid ratio thing; I actually did a small comparison of just the "BCAAs" in various protein sources the other day in another post here (some of this is copied from there):
30g Manitoba Hemp Protein:
30g TP Soy Isolate:
30g Nutribiotic Rice Protein:
30g TP Ion Exchange Whey Isolate:
5g ON BCAA powder:
Please note that the 'ON BCAA powder" totals are for a 5g serving, not the 30g "serving size" included for the other proteins. Sorry I didn't make a chart like Troy did, but it's late and I'm using a calculator so you might even want to check these calculations...
In terms of finding the ideal ratios of aminos, I am inclined to begin the experiment by concentrating on these three (L-Isoleucine, L-Leucine, L-Valine).
I have been toying with this concept for a few weeks, and when I looked at Troy's excel spreadsheed, I noticed that Whey Isolate is pretty high in these three amino acids, relative to the usual "vegan" protein supplements I take.
What I am thinking is that a mix of various protein (gemma,hemp,rice,soy), supplemented with a small amount of BCAA to bring the three "BCAAs" into the range of Whey Isolate... would still allow me to consume "varied sources of protein", but would yield an amino profile (for these three particular aminos) similar to the Whey Isolate.
Am I just crazy, or does this seem like a good place to start???
