VITAMINS
- Introduction
Food
provides the body with the materials it needs for energy,
growth, repair, and reproduction. These materials are called
nutrients. Nutritionists divide nutrients into two main groups:
macronutrients and micronutrients. Macronutrients, so called
because the body needs more of them, include carbohydrates,
fats, and proteins. These are the foods our bodies use for
energy and growth. Micronutrients, or nutrients required in
only small amounts, include vitamins and minerals. Most foods
contain a combination of the two groups.
What
are the different parts of my diet that give me energy?
Macronutrients
provide the body with the energy it needs to work, grow, reproduce,
and repair. Carbohydrates and fats are the body's primary
energy sources. Protein is essential to growth and maintenance.
Here
is a rundown of what each macronutrient does and some good
sources.
Carbohydrates
Carbohydrates include all starches and sugars. They are the
body's main source of energy. Each gram of carbohydrate provides
4 calories. Most foods contain carbohydrates. The main sugar
in food is sucrose, which is everyday white or brown sugar.
Other sugars include lactose (found in milk) and fructose
(found in most fruits and many vegetables). Starches are a
more complex form of carbohydrate. They are more filling and
contain more nutrients than foods with lots of sugars, fats,
or oils. Foods containing starches include beans, breads,
cereals, pasta, and potatoes.
Fats
Fats pack a lot of energy. Each gram of fat provides 9 calories.
There are three kinds of fat: saturated, monounsaturated,
and polyunsaturated. Animal and dairy fats, which remain solid
at room temperature, are saturated fats. Saturated fat is
often called "bad" fat. Unsaturated fats include vegetable
fat and oils; they remain liquid at room temperature.
Proteins
Proteins provide energy at 4 calories per gram, but they are
more important as the body's building materials. Muscle, skin,
bone, and hair are made up largely of proteins. In addition,
every cell contains proteins called enzymes, which speed up
chemical reactions in the body. Cells could not function without
these enzymes. The body uses proteins to make antibodies,
or disease-fighting chemicals, and certain hormones such as
insulin, which serve as chemical messengers in the body. (Other
hormones, such as the female hormone estrogen, are not made
from proteins.) Meat, poultry, fish, dairy products, eggs,
cereals, legumes, and nuts are all good sources of protein.
What role do vitamins and minerals play in nutrition?
Vitamins
help the body turn food into energy and tissues. There are
13 vitamins in all: vitamin A; the vitamin B complex, which
includes thiamine, riboflavin, niacin, vitamin B6, folic acid,
vitamin B12 pantothenic acid, and biotin; and vitamins C,
D, E, and K.
Minerals
are needed for growth and maintenance of body structures.
They also help to maintain digestive juices and the fluids
found in and around cells.
Unlike
vitamins, carbohydrates, fats, and proteins, minerals are
not made by plants and animals. Plants get minerals from water
or soil, and animals get minerals by eating plants or plant-eating
animals.
The
minerals the body needs in large amounts include calcium,
chlorine, magnesium, phosphorus, potassium, sodium, and sulfur.
Other
minerals, called trace elements, are needed in much smaller
amounts. Trace elements include iron, copper, fluorine, iodine,
selenium, zinc, chromium, cobalt, manganese, and molybdenum.

| What
foods are the source of the most important vitamins
& minerals, and how will my body benefit? |
| The
best way to get the vitamins and minerals
you need is by eating a varied, balanced diet,
rich in fruits, vegetables, and whole grains.
This table describes the health benefits of
the most important vitamins and minerals and
the foods you can eat to get those nutrients.
Vitamins are divided into two categories—
fat soluble and water soluble. Fat-soluble
vitamins are found in fats and oils in foods
and they are stored in body fat. Water-soluble
vitamins dissolve in water and mix easily
in the blood. Your body stores only small
amounts of them and they are excreted in urine.
Some vitamins are antioxidants—chemicals that
prevent damaging changes in cells and may
help protect against cancer, heart disease,
and aging. |

Why Supplement? Because Your Body Has to Last
a Lifetime.
Overfed
yet undernourished. Stop for a moment, and consider your daily
eating habits. How often do you reach for junk food instead
of fresh fruits and vegetables? How often do you skip meals?
Does your diet provide variety or do you eat the same things
day after day? If you answered "yes" to any of these questions,
rest assured you are not alone. Most of us choose foods that
satisfy cravings rather than nutritional requirements. The
problem is, we still need a daily intake of over 45 essential
nutrients to maintain optimal health.
Filling
the nutritional void. Since many diets fall well short of
providing everything the body needs, it is important to identify
a good source of essential nutrients. The natural solution
is nutritional supplements. Supplements offer a quick, easy
way to get the vitamins, minerals, antioxidants and important
phytonutrients necessary for optimal health. In fact, a balanced
nutritional program that includes supplements offers important
protection ranging from your immune system to the density
of your bones.
An
investment with healthy returns. When you look at the health
costs associated with poor nutrition and unhealthy lifestyles,
dietary supplements could very well be one of the most important
investments you will ever make. If you are truly serious about
investing in your family’s health, the question is not whether
you can afford to add nutritional supplements to their diet,
but rather, whether you can afford not to.
The Essential Supplements:
Before anyone asks should I use N02, should I
buy any of the those killer nice looking products off the shelf
(Nitric Oxide, Tribulus Terrestris,ZMA,etc.) I would like to
address the essential supplements that actually will deliver
results/ or serve a purpose for teens as well as others in bodybuilding.
These essential supplements are more important then Nitric Oxide
or such and should be the prime objective on our minds if we
use/purchase supplements for bodybuilding. These essential supplements
include Protein, Creatine, Multi-Vitamin and an EFA (Essential
Fatty Acids). This combination alone is basically all we need
to pave our way to better gains at our age.
Protein:
It
provides the body with the necessary building blocks to produce
amino acids that are used for building muscle tissue. We all
know that protein by far is the most important thing our bodies
need when it comes to repairing and building muscle tissue.
Just by these facts alone it doesn't take many words to stress
the importance of protein to bodybuilders or to anyone lifting
weights and expecting to gain muscle. Whey Protein is maybe
the best form of protein out there for many reasons. Price,
effectiveness,quality. As teens we all take into consideration
the fact that we do shop watching our budgets. If we don't
shop for it, it's our parents who watch that. Whey Protein
can range anywhere from $20-$35 for a 5lb container(60-80
servings). Some examples might include: Optimum Nutrition
100% Whey Protein, Dymatize Elite Whey, Syntrax Nectar and
Higher Power 100% Whey. Whey Protein's effectiveness is also
quite impressive. After a workout, our muscles are tired there's
a chance that it will go into a catabolic(muscle breakdown)
state if protein isn't ingested soon. Sure they are lots of
protein to ingest but the beauty of Whey Protein is that it'll
digest in as little as 30 minutes upon ingestion. This will
make sure that our muscles receive the building blocks it
needs to rest up and repair for another day at gym. Whey Protein
delivers a good amount of the quality amino acids we need
for muscle repair and growth. Aside from supplementing Whey
Protein after we workout(Post-Workout) we should make sure
that we get in atleast 1g of protein per lb. of bodyweight
everyday to help increase growth and repair of our muscles.
We can do this by eating high protein, low fat foods such
as: boneless skinless chicken breasts, 97%-98% lean ground
beef, tuna, lean turkey and many other foods that have high
protein and low fat.
Creatine:
What
is Creatine? Our bodies naturally make creatine, which is
used to supply energy to our muscles. It is produced in the
liver, pancreas, and kidneys, and is transported to the body's
muscles through the bloodstream. This high-powered metabolite
is used to regenerate the muscles' ultimate energy source,
ATP (adenosine triphosphate). Many foods especially herring,
salmon, tuna, and beef contain some creatine but their amounts
isn't sufficient enough. After creatine enters the body or
after it is produced by the body it firsts binds with a phosphate
molecule to form Creatine phosphate.When a phosphate group
is hydrolyzed, energy in the form of heat is given off and
this energy is used to drive whatever process is being performed,
for example muscle contraction. Because one phosphate has
been lost from the ATP it is now called ADP (adenine Di-phosphate).
The reaction is as follows ATP=ADP + Energy. Now you have
free ADP as a product from the ATP hydrolysis. ADP is pretty
much obsolete in the body unless it is reconverted into ATP.
Now this is where creatine comes into play. The phosphate
bound creatine donates it's phosphate group to the ADP to
re-form ATP. By allowing you to return ADP to ATP, creatine
will increase your ATP stores, thus allowing you to train
harder and longer.Creatine is a combination of three different
amino acids, glycine, arginine, and methionine.
Thats
where Creatine Monohydrate Powder comes into effect. Price
ranges anywhere from $20-$30 for 1000g of Creatine. Be sure
to watch out for the Creapure trademark to ensure the Creatine
made by that particular brand is 99% HPLC Certified and Pure.
Oral supplementation of creatine increases muscle stores and
may increase muscle strength and improve exercise performance.
Creatine claims to increase energy, power output, and enchances
muscle size and strength.
Creatine also has a cell volumization effect which means that
it will fill up your muscles with water. This effect is a
positive effect because more water in the muscle means greater
nitrogen retention. Since the cell is holding more water,
it can also hold more ions since the ions will follow water
into the cell in order to keep the concentration the same.
When more ions are present in muscle cells (the most important
being nitrogen) muscle protein synthesis also increases. Nitrogen
retention is anabolic simply because amino acids are not exiting
muscle cells. They therefore are available for repair and
growth instead of exiting or becoming an energy source.
*Note: It isn't a bad idea at all to include 5g of creatine
monohydrate in your post workout protein shake along with
45-65g of dextrose(glucose) to help restore glycogen stores
as well as increase uptake of all nutrients in your postworkout
shake. I also recommend that there is a ratio of 2:1 when
it comes to carbs to protein in the Postworkout Shake. For
Example: If you have 30g of protein in your PWO shake, there
should atleast be 60g of dextrose in it. Don't forget to add
that 5g of creatine to it to have a complete PWO shake that
includes: protein, amino acids, creatine, and glycogen replenishment.*
Multi-Vitamin:
Multivitamin and mineral supplements are perhaps the most
important single supplement that can be consumed by bodybuilders
and athletes. Creatine and Whey Protein are also very important.
For
the human body to perform at its maximum potential, it must
be fed a vast and complex array of vital nutrients. Becoming
deficient in just one of these essential vitamins or minerals
breaks down the metabolic pathway that produces optimum efficiency
and performance declines. Not good! Daily consumption of a
high-potency multivitamin/multimineral formula may help ensure
the presence of essential cofactors necessary for thousands
of metabolic reactions.
"Many
people underestimate the importance of them. They think that
since you can not get 10 pounds of muscle, it is useless to
take them. But here is something very important. If your body
is deficient in just one of the essential vitamins and minerals
over a thousand chemical and enzymatic processes in your body
could be impaired. Each and every vitamin and mineral is responsible
for thousands of biochemical reactions, including the formation
of hormones. Bottom line? If you don't use a good multivitamin
and mineral formula you will never reach your fullest potential.
When should you take multivitamin/minerals and extra antioxidants?
Simply take your multivitamin/mineral formula first thing
in the morning, and IMMEDIATELY after your weight training,
take one multivitamin/mineral plus your extra antioxidants.
On the days you don't train, take only one serving of vitamin/mineral
formula in the morning, and in the afternoon take your antioxidant
protection."
