CARBOHYDRATES
Carbohydrates are
sugars that provide energy for the body especially the brain and nervous system. Carbohydrates usually provide
about half of our body’s energy when the body is resting or performing low level activities.
Natural carbohydrate foods are low in calories and
high in fiber. Natural carbohydrates contain about 4 calories per gram however fat contain about 9 calories per
gram. When we eat a food containing carbohydrates,
our body will break down the carbohydrates for energy. An enzyme called amylase helps break down carbohydrates into glucose
(blood sugar) which is used for energy by the body.
When the body doesn’t need to use the carbohydrates for energy, the
body stores the carbohydrates in the liver and muscles cells. When the carbohydrates are stored in the liver
and muscles, it is called glycogen. When the liver and muscles cells cannot store anymore glycogen, the body turns the carbohydrates
into fat.
Carbohydrates
are classified as simple or complex. The classification depends on the chemical structure of the food and how
quickly the sugar is digested and absorbed.
Simple carbohydrates provide short bursts of energy followed by a lowering of blood
sugar and then followed by a decrease in energy. Simple carbohydrates are also known as “sugar”
and are considered “empty calories.”
Examples of simple carbohydrates/sugars include;
1. Fructose (Fruits).
2. Galactose (Milk).
3. Lactose (Dairy Products).
4.
Maltose (Vegetables).
5. Sucrose (Table Sugar).
Complex carbohydrates also known as “starchy”
foods. Complex carbohydrates take longer to digest so the body needs more time to release these carbohydrates into the blood
as glucose.
Examples
of complex carbohydrates include;
Bananas
Barley
Beans
Bran
Buckwheat
Corn
Lentils
Nuts
Oats
Peas
Potatoes
Rice
(Brown & White)
Wheat Germ
Yams
Not getting enough calories especially from
simple carbohydrates such as fructose (fruits), maltose (vegetables) also from complex carbohydrates such as from bananas,
beans and lentils can cause malnutrition.
Getting too many calories especially from simple carbohydrates such as lactose (dairy) and
sucrose (table sugar) can lead to an increase in;
Blood Sugar
Body Weight
Most people should consume between 40%
- 60% of their total calories from complex carbohydrates and simple sugars such as fructose (fruits) and maltose (vegetables).
Complex carbohydrates, fruits (fructose) and vegetables (maltose) provide the body with needed fiber, minerals
and vitamins.
