Nutritional Guidelines for Optimal Performance

The
following is a series of articles through this month I will be focusing
on when we need focus on eating and fueling our body the most. I have
trained in Martial Arts and Energy systems almost my whole adult life,
& almost everyone talks about the practices on what to do but
almost everyone forgoes or does not know about nutritional &
dietary requirements for a serious student.
For starters the
chemicals found in your body are almost like those found in food. Both
consist of at least 18 elements and probably as many as 40. These are
made up of combinations of atoms, such as carbon, hydrogen, oxygen,
nitrogen, calcium, potassium, and phosphorus. Some compounds are
necessary for building and repairing tissues, others protect the body
from disease, and others provide energy and warmth.
A stream
of nutrient chemicals formed from digested food flows continuously into
our cells, providing the energy needed to train, work, play, make love,
and even sit in a chair watching television. When the cells have used
the amount of nutrients required for fuel each day, any excess is
stored in the tissues. Your body can store a limited supply of
carbohydrates and an almost unlimited amount of fat, but protein cannot
be stored. It must be provided by your intake of food with the amount
absorbed by the body being dependent on the quality of protein you eat.
PROTEIN: POWER BUILDING FOOD
Without
protein, there would be no life since it forms the basic substance of
our muscles, bones, brain, nerves, heart, and every other organ. Only
protein contains nitrogen, an essential part of protoplasm. Without it,
the cells would slowly wear away, unable to reproduce and form new
cells. In our body red blood cells have a life of only 18 weeks and
must constantly be replaced. Without a supply of dietary protein
providing the amino acids essential for the reproduction of new cells,
this would be impossible. The same holds true for cells lining the
intestine, which are renewed every 112 days.
The synthesis of
protein is also essential for anabolism, or the formation of new
tissue, occurring at an even rate for the average person that is
stepped up considerably with practitioners of Qigong, Martial Arts,
Yoga & related energetic practices; since we are continuously
training, breaking down tissue, and building muscle mass. Dietary
protein is also essential to catabolism, a process through which the
amino acids found only in protein are broken down, thereby liberating
energy. Again, this would occur at an even rate for those not in
intensive training but accelerates for Qigong & Martial Artist
practitioners and other athletes due to their increased expenditure of
energy.
Proteins also serve a regulatory role in forming
enzymes that trigger all chemical reactions in the body. The body is
protected from infectious diseases by antibodies composed of proteins.
And hormones like insulin that regulate our daily processes are also
derived from our daily intake of protein.
All protein foods
are not equally efficient. Their value is based on the type of amino
acids they contain, which combine with nitrogen and form thousands of
different proteins necessary to build and repair cellular tissue. This
takes place during digestion when hydrochloric acid and enzymes break
down the intact protein molecule into amino acids so they can be
absorbed through the intestinal wall. Of 22 known amino acids, 13 can
be produced by the body, synthesized by glands like the liver.
These-alanine, arginine, asparagine, aspartic acid, cysteine, cystine,
glucine, glutamic acid, glutamine, hydroxyproline, proline, serine, and
tyrosine-are called nonessential amino acids. They can safely be
omitted when enough nitrogen and other nutrients are supplied.
Essential amino acids, used for building tissue and other functions
just discussed, cannot be made by the body but must be taken directly
from our daily intake of food. They are histidine, isoleucine, leucine,
lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Those
who are vegetarians should be aware that one amino acid cannot replace
another. When food contains the essential amino acids it is considered
a complete protein. With the exception of soybeans, all complete
proteins are derived from animal sources: meat, fish, eggs, poultry,
cheese, and milk. Although most gelatin comes from an animal source, it
does not fall into this category because it lacks the necessary amino
acids. Protein foods derived from plants are considered incomplete
since they lack the amino acids essential for building tissue and
repairing the body. Certain plant foods, like rice, potatoes, nuts,
breads, and grain cereals, contain the essential amino acids but in
lesser quantities than animal foods.
Many cereals and rice are
low in lysine, while dry beans, peanuts, and brewer's yeast are low in
methionine. It would be necessary to eat a pound of potatoes to provide
the necessary amino acids found in only an ounce of meat. Keep in mind
that the amino acids of most animal proteins are absorbed efficiently,
their rate ranging from 90 to 95 percent, while the digestibility of
some plant proteins may be as low as 73 percent.
Vegetarians
also run the risk of mis-combining vegetable proteins and thus failing
to form complete proteins containing all the essential amino acids. The
growth and reproduction of cells demand that all the essential amino
acids be ingested at the same time in the same meal. A missing amino
acid cannot be supplied several hours later and still find the
essential ones waiting to be assembled into a complete protein before
being digested. Eggs are a prime example of a complete protein,
containing all of the essential amino acids in sufficient amounts to
maintain life and support growth.
The digestion of protein
begins in the stomach and is completed in the small intestine. Enzymes
from the pancreas actually cause the breakdown of the protein you eat
into amino acids. Following this, they are absorbed from the intestine
and distributed to the body cells through the bloodstream. When more
protein is eaten than needed for the functions mentioned at the
beginning of this section, the excess is metabolized for energy.
If your training requirements contains insufficient carbohydrates
needed for energy, your body will draw on the protein vital to building
internal and external power. This is a mistake many continue making,
particularly when they begin teaching and training at the same time.
Doing energy practices and meditations and forms are Major sections in
ones training; but you must know how to properly fuel your body for
maximum results. In Power Training practices in China it is taught
secretly that many herb, foods & techniques supplement and guide
the success or failure when one trains very serious. If you follow the
suggestions contained within here you will without a doubt make your
integrated practices more powerful, reach new levels & your
body/mind at least 50% or better with little effort.
Another
danger comes from depending on the ever popular protein powders,
tablets, and liquids to supply major nutritional elements. Many
practitioners are using these concentrates believe advertisements that
promote them as highly concentrated food products. Remember, it takes
very little effort to write an advertisement but a great deal to train
serious & hard. Seeing 90 percent protein written on the label
gives the impression that the stuff inside the can originates from a
more valuable protein source than eggs, fish, poultry, or meat.
However,
this does not necessarily mean that 90 percent of the powder is
protein. For example, a can weighing two pounds may contain one pound
of pure protein, 90 percent of which has a nutrient value. The
remaining pound consists of other ingredients added to stabilize the
protein and prevent it from spoiling. At present, the average protein
content of most brands ranges between 40 and 70 percent; some
higher-quality products might supply as much as 65-75 percent.
Even
so, an important difference should be noted between protein from animal
sources and protein in powdered concentrates, tablets, and fruit- and
chocolate-flavored liquids. We define the first as live protein and the
second as dead protein based on the condition of DNA molecules found in
the cells. These molecules work as an information center, having the
codes and blueprints necessary to assemble hundreds of different
proteins needed by the body. Each day they send out thousands of
messages on building and repairing tissue. The DNA in animal protein,
even when the animal is slaughtered, remains alive and unbroken. In the
case of protein powders from animal sources, however, the DNA is broken
down during the manufacturing process, and its ability to build body
tissue is impaired.
Also, the protein in concentrates is not
absorbed into the bloodstream to the same extent as is dietary protein.
This point is one of the chief considerations in the selection of
high-quality protein in your training requirements. The fillers and
waste products contained in the concentrates contain substances that
inhibit enzyme action in the digestive tract, resulting in effective
utilization of the protein. For example, in comparing 4 grams of
protein from an egg yolk with an equal weight of powdered protein, you
will absorb about 3 1/2 grams of protein from the egg, but less than 2
from the powder. Therefore, concentrates should never be considered
substitutes for fresh food, most particularly from animal sources. Any
dependency on them can only set you on the road downhill as a
practitioner.
Those who are underweight may gain an advantage
by taking the powders as a pick-me-up between meals, perhaps using them
to spare protein needed for building muscles, but not to replace eggs,
fish, meat, or poultry. Then it is best mixed with milk or water rather
than fruit juice, since the high concentration of sugar does not
combine well with protein and may putrefy in the colon without being
digested.
As a serious practitioner, you must consider
the net protein utilization (NPU) or rate of protein absorption into
the bloodstream. For those who are trying to shed pounds this should be
highlighted because some meat items are much higher in fat than others.
For example, beef and chicken both have an absorption rate of 68
percent, yet chicken has the advantage of easier digestibility and
contains almost half the calories of an equal weight of beef, pork, or
lamb.
The protein utilization rate of some common foods follows:
FOOD
Eggs 88%
Fish 78%
Dairy products 76%
Meat 68%
Soybeans 48%
Natural brown rice 40%
Red beans 39%
Coconut 38%
Nuts 35%
White beans 33%
Maize 25%
Whole wheat bread 21%
White bread 20%
**% rate is the NPU or rate of protein absorption**
