WHEN YOU EAT PROTEIN WHAT DOES IT DO?
A GUIDE FOR ATHLETES:
PART 3: DAILY AMOUNT OF PROTEIN
Dr Michael Colgan 4 March 2015
In
response to the unexpected hundreds of questions from readers, I have
to review where we are in this series. In Part 1, I documented the huge
advances in the Proteome Project since 2005, confirming how protein is
far and away the most complex nutrient in your diet (1).
You Are a Protein Machine
We
know now that food proteins provide the environmental signals to
release the DNA codes for over 350,000 different proteins that compose
every working unit in your body. All other nutrients, essential fats,
carbohydrates, vitamins, and minerals are simply supports for your
protein system (1). There is no controversy regarding this science. It
is accepted by all major scientists I know.
Food proteins provide
not only the signals to your DNA, but also provide the raw materials to
make each of your body proteins, in response to the release of its code.
Each body protein code is precise. Different proteins can differ from
each other by many thousands of lines of code. Your structure is built
of, and you are operated by, these proteins. The quality of the protein
you eat, determines the quality of the proteins that compose all the
muscles that move you, and all the brain cells that operate your mind
(2).
You Are Controlled by Light
I
also explained how the manufacture, life, and regular death of all the
proteins that compose us, (and all other creatures), developed under the
tight control of light. This first occurred when life began on Earth
over 400 million years ago. The life of all our proteins is still
controlled by light today (3,4). By stimulating an area called the
suprachiasmatic nucleus in our brains, the changing light of the
revolution of the Earth, imposes a circadian rhythm which controls every
aspect of human biology, 24 hours a day, including the birth, and life,
and death of all our proteins. To achieve optimum performance, the
quality, type, amount, timing, and frequency of your protein nutrition,
and its integration with athletic training, have to be in synchrony with
this circadian rhythm (3,4). In combination with correct training,
protein nutrition provides what we first termed THE ADAPTIVE STIMULUS in
1982. The body responds to the adaptive stimulus each night to repair
and remodel the muscles stimulated by exercise that day. To achieve best
results, the adaptive stimulus must be provided EVERY DAY. Otherwise,
that particular circadian cycle finishes that night with little
remodeling of muscle, and that day’s opportunity for growth of muscle
and strength is lost forever (3,4).
Most Proteins Now DegradedIn
Part 2, I explained how the bulk of proteins in America, from
livestock, poultry, (and farmed fish) has been progressively degraded
since 1950. Stupid errors in government farming policies - now
constantly denied and swept under the Washington carpet - have forced
most animals off the land into feedlots and battery farms. Over the last
65 years, they have been fed unnatural diets, and inbred into animal
grotesques (5). These degraded animals provide proteins so inferior they
have no place in the athlete’s diet. Eat battery chicken for your
protein and you will devolve progressively into a battered chicken. You
will run with battered chicken legs, and think with a battered chicken
brain. Even if you manage to retain sufficient wits to change to a
healthy protein diet, it will take several years to undo the damage
(5).High BCAA Whey Proteins BestI also showed why the government
classification of complete proteins by the PDCAAS system, developed in
the 1970s, is obsolete and untenable (6). The PDCASS is retained today
only to support agribusiness profits. I documented how modern science
shows clearly that incorporation of a food protein into muscles, organs,
and brain, depends on its amino acid profile (7-10 ). Proteins with the
highest content of the three branched-chain amino acids (BCAA),
leucine, isoleucine, and valine, are incorporated into muscle best.
Leucine however, is the sole amino acid able to trigger the DNA code
system to release the codes for many muscle proteins. Whey proteins have
the highest content of leucine, making whey the amino acid profile of
choice (7-11 ).
Proteins also differ greatly in their
speed of digestion and absorption into muscle. The fastest proteins
yield the greatest muscle recovery and growth (7-12). Solid proteins
from meat, fish, eggs, cheese, and vegetables are slowly digested and
absorbed over 2-4 hours. Almost all protein bars, especially bars high
in casein or soy, and all casein and soy drinks, are also slowly
digested and absorbed over 2-3 hours. Whey protein concentrate dissolved
into a drink is rapidly digested and absorbed, over about 45 minutes,
making whey an ideal protein source for athletes (7-13). Whey is also
the only commonly available protein that can take advantage of the
90-minute ANABOLIC WINDOW immediately after training. This is the
crucial period we first identified in 1992, during which muscle will
take up more protein than at any other time (2).
Cold MAP Processing EssentialThe
whey, however, has to be from range-fed animals eating their natural
diet, and also has to remain undenatured. That is, it must be
cold-extracted and minimally processed, using what is termed,
modified-atmospheric-protection (MAP) technology. MAP technology
excludes light, heat, moisture and air (2).
Range-fed
cows, cold-extraction, and MAP processing, are essential to maintain the
quality of the whey: to preserve its amino acid profile, sulfur bonds,
di-peptides, tri-peptides, and live immunoglobulins. Most commercial
whey proteins do not fulfill these conditions.
Unfortunately
bogus claims are rampant on ads and labels, owing to the lack of
government control of protein, which can be sold freely as a food. Food
labelling was initially meant to be an exercise in revelation, to inform
the public what they are buying. Over the years, it has become largely
an exercise in deception.
If you buy nutritional
supplements by comparing labels, you have fallen for this deception. Buy
only from companies with a long-term, spotless reputation, companies
with a reputation to lose. Remember, you can buy a watch that looks like
a Rolex in any airport for $20. But a real Rolex costs at least $4,000.
It is the same with protein. The real thing is likely to be expensive,
but worth every penny.
Integrity of Protein Must Remain Until You Eat ItThe
exclusion of light, heat, moisture, and air has to prevail until you
eat the protein. Once opened, all tubs of protein powder immediately
begin to oxidize. Just like an opened bottle of wine, once opened, tubs
of protein quickly spoil, and lose their ability to build muscle or
brain. This basic science is well appreciated by biochemists who have to
prevent oxidation, in the laboratory. But about 90% of protein powders
now on the market do nothing to prevent oxidation, and are next to
useless for athletes.
Oxidized protein is a major reason why
results from using many protein powders are generally poor to none. It
is also why all athletes on Colgan Institute programs only use shakes
made with whey protein powders sold in single-serve, sealed, opaque,
foil or plastic packets. If kept cool and dry, these remain good for two
years on the shelf.
Daily Amount of ProteinThe
next question is how much protein to use every day. Modern science has
long since rejected the obsolete, government stipulation of 0.8 grams
per kilogram bodyweight per day. Controlled studies show clearly that
this level of protein intake leaves even moderate exercisers in chronic
deficit (14).
Back in the 1980s, we calculated from basic
principles of biology that maximum muscle remodeling in lean athletes
would occur at an average intake of top quality protein of 1.8 grams per
kilogram bodyweight per day (15). Actual measures of nitrogen retention
in lean, fit, young men doing intense exercise, by protein expert Dr
Peter Lemon at Kent State U, showed maximum incorporation of protein
into muscle of at 1.7 grams per kilogram bodyweight, almost identical to
our theoretical calculations (16).
For a lean athlete of
70 kg (154 lbs), in hard training, that is about 130 grams of top
quality protein each day. In the Colgan Power Program, it equates to
three of our 36-gram shakes of whey protein concentrate, plus two small
meals of free-range meats or eggs, wild meats, or wild fish, plus
unlimited organic vegetables, seeds, and nuts, each day.
We
generally eat little to no grains, milk, cheese, or sugars. Two of the
protein shakes are taken immediately after training, as all our athletes
train twice per day, six days a week. (Seventh day is light training
only.)
More recently, respected sports scientists have
done meta-analyses of the best controlled studies. Results indicate that
additional remodeling of muscle, plus remodeling of gut, vascular, and
mitochondrial proteins, continues to occur over 24 hours after training,
with timed protein intakes up to 2.4 grams per kilogram lean mass per
day (17-19). There are no reported side-effects from this level of
intake, rather, considerable benefits.
This high level of
protein is especially suitable for power athletes, such as
weightlifters, bodybuilders, powerlifters, football players, and field
athletes, whose training is focused on maximum muscle and strength. For
an athlete of 70kg (154 lbs), that is about 170 grams of top quality
protein per day. In the Colgan Power Program, it equates to four of our
36-gram shakes of whey protein concentrate, plus two small meals of
free-range meats, or wild meats, or wild fish, per day. Excepting for
potatoes, that are all now degraded in the US, we eat vegetables, nuts
and seeds freely.
Eat between 1.8 and 2.4 grams of top
quality protein per kilogram lean weight per day. In conjunction with
the right timing and frequency of intake, and the right training, it
will provide the adaptive stimulus you need to release the enormous
genetic power you have latent in your genes.
I will cover the optimum timing and frequency of protein nutrition, and its integration with training, in Part 4.
Thanks
a million for the huge response to this series, over 80,000 hits on our
pages and blogs in the last week, and for the enormous number of great
questions. The only way I can answer readers is to add a little more
depth to each short article in the series. I will enjoy revealing the
new findings of sports science, that I am confident will help you
release your athletic potential. Go for the gold ! It is waiting in your
genes.
