Many of you know that whey (isolate) is the fastest way to absorb protein, but the efficacy of taking 30 grams or so of protein depends on how your body will utilize it in your digestive system. With protein shakes, you can absorb about 10 grams of protein per hour, while with whole foods your body can absorb 2-5 grams per hour.
