Protein Supplements Vs. Protein Foods(continued)

Another acknowledged benefit of whey protein is its fast absorption rate. Although there isn’t any evidence that protein supplements digest more efficiently than whole foods (as is often claimed), they are definitely digested faster. This is most important after a training session when the rates of protein synthesis and glycogen re-synthesis are increased. This is the reason it is often recommended that a liquid meal containing protein and a high glycemic carbohydrate be consumed immediately post-workout and that whey is the ideal protein for this purpose. Even in considering post-workout nutrition, there is still little proof that a liquid protein-carb complex will actually produce better muscular growth than whole foods, as long as complete whole food protein foods and complex carbohydrates are consumed immediately after the training session and every three waking hours for a period of 24 hours thereafter.

Speaking of protein absorption rates, the discussion of fast acting versus slow acting proteins seems to be the latest hot topic these days in bodybuilding circles. The interest was sparked by studies in 1997 and 1998 that examined the differences between the absorption rates of whey versus casein. The researchers concluded that whey was a fast acting protein and was considered to be more "anabolic" while casein was slower acting and was considered to be more "anti-catabolic. " It was further hypothesized that consuming a combination of these two types of proteins could lead to greater muscle growth. These findings have prompted the supplement companies to market an entirely new category of protein supplements; casein and whey mixes. The problem with drawing such conclusions so quickly is that these studies looked at the speed of whey and casein absorption in subjects who had fasted for 10 hours before being fed the protein. Any suppositions drawn from this information are probably irrelevant if you are eating mixed whole food meals every three hours. Obviously, more research is needed.
