Whey Protein

New directions / the future for whey
There are several interesting directions in the development and
processing of the next generation of whey proteins.
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
Most people remember
hydrolyzed proteins were all the rage a few years ago, then dropped off
sharply. "Hydrolyzed" basically means the protein has been
broken down partially into peptides of different lengths. Because the
protein is already partially broken down, it is absorbed faster, which
may have positive effects under certain circumstances, and certain
metabolic conditions (i.e., burn victims or people with certain
digestive disorders and pre-term infants). Whether or not hydrolyzed
proteins are truly an advantage to athletes has yet to be proven.
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.
