Whey Protein: the ultimate nourishment
protein in terms of bioavailability (around 100) and
content of essential amino acids, which the body needs on a daily
basis to promote a
healthy body and assist in maintaining
tone. Whey protein is a by-product of cheese making, which
has been concentrated and purified by a filtration process to yield
a high purity protein product, that is both natural and pure without
any added preservatives.
amount of protein in Whey Protein Concentrate is 22 grams
per serving and the balance is made up of 2 grams
fat, 2 grams
carbohydrate and a mixture of
minerals amounting to less than 1
gram. All the Whey Protein Isolate is the purest form of whey
protein and contains 25 grams of protein per serving, less than 1
gram of carbohydrates, less than 1 gram of minerals and trace
amounts of fat.
Without protein, you may spend hours in the gym and never
increase your lean muscle mass simply because you cannot grow
a muscle without protein.
Benefits of Whey Protein:
research shows that itís best to consume whey protein two hours
before exercising - after exercising, within two hours or less.
This is the time when the body needs protein the most. More recent
studies have reduced this time to as little as 15 minutes. Whey
Protein digests easily to start nourishing muscle tissue in
need of repair. It has a high concentration of branched chain
amino acids (BCAAs) which are used by muscle fibers during
exercise. The body prefers to use BCAAs during periods of exercise
as a source of energy. The muscles break down BCAAs into glucose
which passes directly into the skeletal muscles from the
bloodstream. Low levels of BCAAs may lead to increased fatigue,
endurance exercise. Whey Protein replenishes the BCAAs to help prevent muscle fatigue, produce favorable
psychological effects, improve performance, and foster faster
recovery after intensive exercise.
Whey Protein contains a protein
fraction known as glycomacropeptide, which is a powerful
stimulator of the pancreatic hormone cholecystokinin (CCK).
CCK is an appetite suppressant that plays many essential roles
relating to gastrointestinal function, including the regulation of
food intake. Also, CCK stimulates gall bladder contraction and
bowel motility; regulates gastric emptying; and stimulates the
release of enzymes from the pancreas.
Certain specific types of hydrolyzed
whey protein show promise in helping to naturally reduce blood
Blood Pressure). While whey proteins should not be substituted for
prescription medication, they may be a good complement to your
current program. Look for more information later this year.
Whey Protein is a very useful and
key component in
programs. Protein has long
been known to provide a higher level of satiety versus
carbohydrates, and may help dieters feel less hungry between
meals. The Journal of the American Dietetic Association compared
the effects on
body weight and composition of two
diet plans. One
plan included liquid protein meal replacements, and the other
followed a more traditional approach. At three months, both groups
experienced significant weight loss. After one year, most of the
participants in the protein
supplement consuming group maintained
weight loss, while the traditional group regained
most of their weight.
protein has been researched in prevention and life extension
studies for such things as
cancer, AIDS and other degenerative
diseases. It may help T-cell activity and decrease wasting tissues
during illness and therefore increase well-being and the speed of
overall recovery. Whey proteins contain high levels of the amino
acid cysteine, which is needed to help the body produce
glutathione, a powerful anti-oxidant that plays a key role in
immune health. In fact, one of the first symptoms
often noticed in individuals with autoimmune diseases, such as
HIV, is a decline in glutathione levels. Numerous studies have
demonstrated the positive effects of whey protein supplementation
on individuals with various types of cancer, chronic fatigue
syndrome, and HIV. One recent study found that whey proteins
inhibited the growth of
breast cancer cells in a test tube.
Another study showed a reduction in the size of cancer tumors in
some patients when they consumed a whey protein product that
delivered 24 grams of pure whey
protein per day.
Whey Protein provides High Quality Protein For Those on Lactose,
Casein or Gluten Restricted Diets-- Whey protein isolate is
the purest form of whey protein and is made up of over 90 percent
protein. It contains only trace amounts of lactose therefore
individuals with lactose intolerance can safely take whey protein
isolate. It is also a great protein source for individuals with
Celiac disease who are on gluten or wheat protein restricted
Osteoporosis, is a major health concern. Studies show that low
protein intake, including lower levels of animal protein intake,
is significantly related to increased levels of bone loss. Regular
exercise and adequate amounts of protein and calcium in the diet
can make a positive difference to bone health and may help
to reduce the incidence of osteoporosis.
Exciting new research is being
conducted that indicates certain whey protein components help
promote the growth of new body tissue. This work is ongoing
and still in the early stages.
protein comes in three, distinctly different types, of which
some are better than others, depending on different factors. One of
great importance is absorption, followed by the price.
Hydrolyzed Whey - Protein Isolate (HWPI)
In the whey protein family, Hydrolyzed Whey Protein is the most
readily digestible. While having the highest efficacy of all the
whey proteins it is also the most expensive. HWPI is partially
utilized to aid in the human digestive process, which makes it very
soluble. The problem with HPWI is that it has an extremely bitter
taste that is impossible to overcome with sweeteners or flavorings,
which prevent it from possibly ever becoming a primary ingredient in
this class of protein supplementation. HPWI still can be found in
some supplements but as one of the lesser ingredients.
Whey Protein Isolate (WPI)
WPI has a good taste and is also extremely digestible. WPI is almost
entirely void of fat and is lactose free. The latter is of great
importance to individuals with lactose intolerance. The process of
cross-flow microfiltration helped to revolutionize this type of
protein. This is the phase in processing which follows the
"concentration" phase to "isolate" the whey protein.
Whey Protein Concentrate (WPC)
Whey Protein concentrates have a variety of different problems
associated with them. Symptoms from users of WPC included bloating,
gas and in some cases diarrhea. There is a very large variance in
the protein content itself. Actual protein content can vary widely
from twenty-five (25) to eighty (80) percent that is a direct result
of the dependence on the quality and cost. If you were to compare WPI
to WPC you will find that WPC has higher concentrations of fat,
carbohydrate and lactose. The absorption is also reduced due to the
lower assimilation in the stomach and intestines. Due to the lower
cost of manufacturing and the reduced quality and quantity of the
protein content, this is the most economical.
sedentary, unstressed people, the recommended daily protein intake
level is approximately 0.4g per pound of body weight daily (60g of
protein per day for a person weighing 150 lb).
At the other end of the scale, for people on an intense training or
workout program, up to 1 g. of protein per pound of body weight is
ideal to fuel the muscle tissue. At this level of consumption, it is
recommended to spread the protein intake over a number of
through out the day to allow for efficient assimilation of the
protein by the body.
protein is readily available in a concentrated powder form and may
be purchased in nutrition or
health product stores, in many large
grocery stores, or directly from suppliers on the Internet. There
are many ways to consume whey protein as it can easily be added to
water, juice or other liquids. It can also be added to softer solid
foods, such as applesauce, or used as an egg replacement in many
