How Nutrition Effects Your Health
Part II: Not All Calories Are Created Equal
The path to a healthy weight does not have to
be complicated. The two most important pieces
to losing weight and maintaining a healthy weight
are physical activity and nutrition. And there
are two components to nutrition: the quantity
of calories and also the source. In Part I, the
quantity of calories consumed was discussed. Now
it is time to discuss the source of calories.
The source of calories is not only relevant to
how much body fat you carry but also to your health.
When it comes to dietary intake, there are six
essential nutrients for the body. Essential indicates
that the body cannot make them on its own and
therefore these nutrients must be ingested. The
six are: Carbohydrates, Protein, Fats, Vitamins,
Minerals and Water.
Carbohydrates are often blamed for the cause
of making people fat, but the truth is that the
type of carbohydrates that are consumed are to
blame. Carbohydrates actually provide glucose
which runs the body. They provide the body with
its energy source. Carbs provide four calories
per gram and standard guidelines indicate that
between 55 to 65 percent of daily calories should
come from calories. The majority of a person's
carbohydrates should come from whole grains, fruits
and vegetables. Yet, Americans tend to get half
of their carbohydrates from things like cakes,
donuts, cookies and other empty calories. These
do not promote good health. They have very little
fiber, vitamins and minerals.
Protein: It provides amino acids which are the
building blocks of the body's structure and are
required to keep the structure sound. It provides
four calories per gram. Protein makes up the immune
system, enzymes, hormones and carriers and it
builds and repairs. Approximately 10 percent of
daily calories should come from protein. Those
calories are found in both animal and vegetable
sources. When choosing the animal sources, choose
as lean of options as are available.
Fats: All fats are not created equal. Some fats
are needed by our bodies but some are very harmful.
Saturated fats are one of the most detrimental
to ones health. They can cause an increase in
LDL cholesterol. Trans fats are also not beneficial
and actually can be harmful. These fats are often
found in crackers and baked goods. Monounsaturated
fats, canola and olive oils are better fat choices.
Canola oil is rich in omega fatty acids. Flaxseed
and fatty fish are also high in omega 3 and therefore
are health choices. Americans tend to eat too
many omega 6 fatty acids and should instead be
replacing some of those with omega 3 fatty acids.
Fats are the densest source of calories generating
9 calories per grams (that's more than twice the
amount found in protein and in carbohydrates).
Vitamins: They have no caloric value, but are
very important in the production of energy. Vitamins
are only needed in very small amounts. More vitamins,
is not better. A teaspoon holds all of the vitamins
needed in a day. Individuals should not consume
more vitamin supplements then the RDA recommendations
because that could result in serious side effects.
It is very difficult to get too many vitamins
and minerals solely from food sources. But when
taken as supplements, overdoes can occur.
Minerals: Minerals are elements so they cannot
be broken down or destroyed. Taking supplements
on one type of mineral can make an individual
deficient in another mineral. So, mineral supplements
are not recommended without the direct instructions
of a licensed medical professional.
Water: By far the most important element. The
body can only survive about 3 days without water.
How can you tell if you are getting enough water?
You should urinate about every 2-3 hours and the
urine should be a pale yellow color.
Knowing the details about the six essential nutrients
can help you make better food choices. Also keep
the following recommendations in mind:
. Eat a variety of foods
. Try to fill your plate at each meal with a variety
of different colors of food
. Keep your fat intake to 30% or less
. Avoid saturated fats
. Restrict your sugar intake
. A diet should be moderate in sodium
. Include fiber in your daily diet - good sources
include: whole grain cereals, barley, bulgur
