Carbohydrates
are the main source of fuel for the body, and are
broken down to glucose for energy to go the brain
and other areas of the body. Carbohydrates have
been one of the most discussed nutritional issues
of the last decade. Initially, starches were considered
amongst the most fattening food products. Then
in the 80's, people in the United States were urged
to ingest carbohydrates in an effort to reduce
the amount of fat in their diets. Many individuals
were consuming diets whose carbohydrate content
provided over 70% of their total calories. Many
health organizations suggested that Americans get
every bit of fat out of their diet by replacing
much of their diet with "fat-free foods."
The problem that most people
discovered with these diets was that they neither
lost weight nor were they able to successfully
adhere to the diet for any great length of time.
The reason, simply stated, is that protein and
fat are necessary in our diets for a multitude
of reasons, not the least of which are to increase
satiety (the sense of no longer having hunger)
and to stabilize blood sugars. Eating a mostly "fat-free" diet
can cause a rapid rise and fall in blood sugars only
to re-stimulate the desire to eat and increase food
cravings. Therefore, a balance of carbohydrate, protein
and fat is essential to any type of lifestyle nutrition
regimen.
Healthy forms of carbohydrate include fruits, vegetables,
dairy products (which contain milk carbohydrate),
and grains. Eating a lot of carbohydrates from snack
foods, breads, starches, bars, desserts, etc. does
not contribute to health and can contribute to weight
gain if one over exceeds their caloric needs.
Carbohydrates provide 4 calories per gram and are
broken down and digested within one to three hours
of eating a meal. They provide the body with B vitamins,
fiber, and minerals. The approximate recommendation
for carbohydrate is between 45-60% of total calories.
