Bioactive whey fraction protein

A new generation of whey products known as Bioactive Whey Fraction (BAWF) protein is soon to hit the market place, and has the potential to be a worthwhile addition to an athlete's diet. These new BAWF proteins provide the benefits of high protein levels (>70%) accompanied by greatly increased levels of bioactive health-promoting compounds. This innovative product contains all sorts of interesting compounds not found in significant concentrations in either whey isolates or concentrates. BAWF protein contains far higher total growth factor levels comprised from IGF-1, TGF-?, and TGF-?. It contains much higher levels of various phospholipids and various bioactive lipids, such as conjugated linoleic acid (CLA), phosphotidyl-serine, phosphtidyl-choline, sphingomyelin, and higher levels of immunoglobulins and lactoferrin.

Although data is lacking, studies will likely be completed to demonstrate BAWF protein's effects related to athletes' muscle mass or performance. Current studies do suggest these compounds can improve immunity and intestinal health, and have many other effects that both athletes and less active people alike may find beneficial. The differences in the levels of these compounds between this BAWF protein compared to standard concentrates and isolates is not minor. For example when comparing a BAWF protein to a typical concentrate (e.g. WPC 80), the BAWF protein has 350% more lactoferrin, 400% more CLA, 200% more PS more and PC and 150% more IGF as found in the concentrate. The differences are even larger between BAWF protein and an isolate as isolates have only trace amounts of PS, PC, and CLA.

Optimizing subfraction ratios

Another fairly new development in whey processing is the ability to isolate certain bioactive subfraction proteins on a large scale from whey proteins, such as lactoferrin or Glycomacro peptide, using some of the processing methods mentioned above. This was not possible to do on a large scale just a few years ago, but can be done today with modern filtering techniques employed by a small number of companies. This allows for a truly tailored protein supplement; the ability to add back in certain subfractions in amounts that can't be found in nature. Take for example the subfraction lactoferrin. In many whey products, it is nonexistent due to the type of processing employed. The best whey products will contain less than 1% lactoferrin-and more like 0.5%-of this rare but important micro-fraction. Some companies are now able to add in a specific subfraction to get a truly "designer" protein. One company is also working on making an isolate that will have higher levels of the beneficial subfraction alpha-lactalbumin, and lower levels of the more allergenic and less nutritive subfraction Beta-lactoglobulin. "High alpha-lac" whey isolates would be potentially superior to what is currently on the market in large scale production.

Hydrolyzed proteins make a comeback

The hype over hydrolyzed proteins was largely based on one rat study that found fasted rats given Hydrolyzed protein had higher nitrogen retention then rats fed whole protein. Human studies have shown that whey peptide-based diets in patients with cancer and crohn's disease result in enhanced nitrogen retention and utilization. To date, no one has followed up with a human study with healthy athletes showing the same thing.

Regardless, the reason Hydrolyzed protein supplements never became more popular was due to the fact they tasted awful, were expensive, and lacked enough data to really support their use. The way they were produced at the time also denatured the protein heavily. One company has a method for Hydrolyzing whey protein that uses an enzymatic process that tastes OK and does not denature the protein. It also appears to be fairly cost effective. This type of Hydrolyzed whey may have some interesting, albeit poorly researched, applications for bodybuilders and other athletes.

Got milk minerals?

Another potentially useful product to bodybuilders and other athletes is a process for extracting milk minerals from the milk. This yields a highly bio available form of calcium without the fat and lactose of dairy products, and also contains other minerals and nutrients, such as magnesium, phosphorus, potassium, and zinc, needed for optimal bone formation and metabolism. Recent research suggests that higher calcium intakes are associated with lower blood pressure and other positive effects on health.

Most interesting to bodybuilders and other athletes, however, is a growing body of research that has found that higher calcium intake leads to reduced body fat levels and may help shift the metabolism to increased lipolysis (fat breakdown) and decrease lipogenesis (formation of fat). Though bodybuilder types don't tend to suffer from bone density issues, many may not be getting an optimal intake of calcium to see changes in body fat levels. This new milk mineral product added to various protein formulas might be just what the anabolic doctor ordered for athletes looking to minimize body fat and maximize muscle mass.

Conclusion

Well there you have it. I hope this article finally clears up the major confusion people have surrounding whey, so you can now be an educated consumer when you go to buy that next can of whey. Don't be fooled by the hype. Whey is great stuff for many reasons, but you won't "add mounds of muscle in ultra short time" from the simple addition of whey to your diet. I also suggest people keep an eye out for some of the newer developments I outlined above that will probably be finding their way into the next generation of whey-based formulas.
