Although I am inclined to support your assertion about whole food's superior anabolic potential when compared to whey powdered sources, the concentration of amino acids, rapidity of digestion, and the ability to explicitly control serving sizes and macro nutrient content of meals all add up to demonstrate whey's staying power and worthiness.
Also, within the entire vast body of science and research that has been conducted on human protein metabolism and nitrogen retention, there has yet to be a single study that can validate and quantify whole food as being more efficient and proliferative with regards to amino acid pool replenishment, nitrogen balance, catabolic avoidance, and recuperative ability.
