Carbohydrates:
Why We Need Them and Which Ones to Eat
We live in a time where most individuals either believe that carbohydrates are good or bad. For many people, there is no mixing of the two opinions. This article will explain why our body does, in fact, need carbohydrates and which ones are the best.
There are two
types of carbohydrates – simple
and complex. The group of
simple carbohydrates mainly
consist of fructose (which comes
from the sugar of fruits),
sucrose (everyday table sugar),
and lactose (sugar found in milk
and milk products), plus several
other types of less common
simple sugars.
Complex carbohydrates, on the other hand, are also composed of sugars, but these sugars are linked together in long, complex chains, thus making them harder to break down and slowing down the process of their digestion. Complex carbohydrates are found in foods containing fiber and starch such as whole grains, beans (legumes), peas and vegetables.
After ingesting either type of carbohydrate, the body’s digestive and enzymatic systems go to work breaking down the sugar molecules into the basic molecule of glucose. Glucose is the main source of energy for all of the cells of the body and is the only
fuel source for red blood cells
and the brain.
Therefore, the
body must have a source of
glucose in order to function!
In some extreme cases, if
carbohydrates are eliminated or
are lacking from the diet
entirely, the body will attempt
to compensate by breaking down
fat first and finally, muscle to
use as an alternate, but less
efficient, energy source.
For some people, this is desirable, as they wish to burn and get rid of excess fat. For short periods of time the body can run relatively well on the energy released from the breakdown of body fat in place of carbohydrates and glucose. However, if this persists for any length of time, a build-up of ketones,
which are by products of fat
metabolism, are found in the
blood resulting in a condition
known as ketosis. Ketosis
is not a good condition to be
in, as it makes the body
extremely acidic and in some
cases may lead to coma or death.
Therefore, the body does need a source of carbohydrates to function optimally. However, there are choices that can be made as to the type of carbohydrates that are consumed. Complex carbohydrates are the best choices as they have a slow rate of digestion and bring large quantities of fiber into the body.
When choosing carbohydrates to add to meals, stay away from the simple, refined carbohydrates such as bread and pasta products made of white flour, pastries with high sugar content, candy, and all types of soda. Not only will eliminating these simple sugars from the diet help to stabilize the body’s chemistry, but weight loss has also been associated with their removal.
Instead of
these simple carbohydrates, try
other, more nutritious simple
carbohydrates such as fruits
(not fruit juices, but the
actual whole fruit itself), and
complex carbohydrates which
include all whole grains (whole
wheat, barley, oatmeal, and
brown rice to name a few),
legumes and nuts.
Additionally, add plenty of
fibrous vegetables to the diet
to improve the function of the
elimination system as well as
help to keep the body balanced
and healthy.
