Good Carbs vs. Bad Carbs - Choose The Right Type
of Carbohydrates
Foods
are made up of three macronutrients that provide calories in the
diet: protein, fat and carbohydrate. Carbohydrate and protein provide
four calories per gram while fats provide nine calories per gram.
It's important to include the proper balance of these three nutrients
in your menu planning to ensure a healthy diet.
Carbohydrates have been in the news for the past few years, mostly
as a result of the flood of diet books in the market, with the Atkins
and South Beach being the two most popular. Both diets distinguish
between complex and simple carbohydrates, which are often referred
to as the "good and the bad" carbohydrate, respectively.
All carbohydrates contain sugars, which eventually get converted
into glucose, our body's major fuel source. While our muscles can
get energy from other metabolic processes in our bodies, our brain
depends on glucose, exclusively, for its proper function. The two
carbohydrates differ in many ways, but mostly on how quickly the
body processes them. Complex carbohydrates are not refined and have
more fiber, so the body processes them more slowly. Examples of
complex carbohydrates are: fresh fruits, vegetables, whole grain
bread, legumes, brown rice, sweet potatoes, and whole-wheat pasta.
Simple carbohydrates have either been stripped of their fiber through
manufacturing or are naturally low in fiber to begin with. Because
of this, the body metabolizes them more quickly. Examples of simple
carbohydrates are: granulated sugar, corn and maple syrups, honey,
molasses, fruit juices, soda, white bread and white pasta. Naturally
occurring sugars like lactose, found in milk products, and fructose,
in fruit juices are also referred to as simple carbohydrates.
Eating too many simple carbohydrates can lead to weight gain because
the quick blood sugar rise triggers the release of the hormone,
insulin. Insulin's main function is to lower blood sugars but it
also transports fat around your body. An overproduction of insulin,
also called hyperinsulinemia, results when your body finds itself
having to produce more insulin in order to achieve a normal blood
sugar level. You may notice how hungry you become soon after eating
a bagel or a plate of pasta. This occurs because when you eat these
simple carbohydrate- rich foods, the surge of insulin causes your
blood sugar to drop, sending out a sensation of hunger. Our instinct
is to reach for a quick acting carbohydrate to get our blood sugar
up. It's your body's message telling you it's time to eat.
It's important to have a balance of protein, fats and carbohydrates
in your diet, with the emphasis being on more complex carbohydrates
and less simple ones. An easy way to ensure the right kind of carbohydrates
is to choose whole grain bread and cereals at breakfast, legumes
(bean based soups, vegetarian chili) at lunch, and to include vegetables,
salads and grains such as brown rice, bulgur, or whole-wheat pasta
at dinner. Select fresh fruits for desserts. Good snack choices
include fresh or dried fruit, a whole grain granola bar, or hummus
with vegetable sticks or whole grain crackers.
