But then the question remains.. how much of each becomes balanced? Is it just 1 for 1? So one brown rice protein combined with 1 red bean protein makes available all protein amino acids? In which case, wouldn't it be more accurate to say that 1 rice protein plus 1 bean protein equals 1 complete protein? If so, it would be silly to just add the proteins together and leave it that. And then, how much of what amino acids are "left over" - for example, if, hypothetically, for the sake of explaining what I mean, one had 3 of 9 amino acids and another had 8 of 9, there would be 2 "left over" amino aicds which still have a function depending on what they are. So in which case, 1 + 1 = 1.2, 1 being the complete protein, and .2 being the "extra" amino acids, which could be further combined with some other ingredient in a recipe. What exactly is the math of the complete protein in the case of red beans + brown rice?
And for sake of comparison, are meat proteins necessarily complete? Or is it that some proteins in meat supply one or another set of amino acids and taken together they are complete? Because I sometimes mix in a bit of ground beef (72% lean, fats drained) into a rice and bean recipe.
