What Is The Role Of Carbohydrates?

A person getting ready to embark on a weight loss or exercise program will undoubtedly be making some changes in her diet. These changes involves looking at the food she eats and its nutrient content including carbohydrates fats and protein.
While the body uses carbohydrates for many functions their primary purpose of energy production. They deliver fuel mainly on the central nervous and musculoskeletal systems
How Carbohydrates Supply Energy
The carbohydrates in the diet may be simple single molecules called monosaccharides or complex combinations called polysaccharides. Whatever is eaten carbohydrates eventually end up with the same fate: they are processed by the body to produce energy and water
One of the simplest forms of carbohydrate is glucose. . Glucose found in a variety of foods. During digestion it is broken down by the small intestine circulates in the blood and are delivered to the organs and tissues in the body. If blood can not provide enough glucose for the body’s immediate needs it can break down stored carbohydrates in the form of glycogen stored in the muscles and liver.
In situations where the body does not receive carbs that are needed (eg during fasting or prolonged illness) it can break down fat and protein and convert them into glucose to provide energy.
Carbohydrates and Central Nervous System
The brain and nervous system depends on a ready supply of glucose. Anyone who ever felt lightheaded after fasting or skipping a meal has experienced one of the brain’s signals that it needs more fuel.
Carbohydrates and muscular system
Next to the nervous system the musculoskeletal system is most dependent on a ready supply of carbohydrates in the form of glucose. There are two primary sources :. Glucose circulating in the blood and stored glycogen in muscles
If your muscles do not have enough glucose to meet their needs they can treat fats and proteins as a secondary fuel supply and convert them into carbohydrates but only for short periods of time. Muscles using fats and proteins produce nitrogen and ketone bodies as byproduct SOF energy production. An accumulation of nitrogen and ketones can be toxic to the body.
Carbohydrates supply dietary fiber
In addition to supplying fuel for the body carbohydrates are also a good source of fiber. Fibres are available in many different types of fruit vegetables and grains and has been shown to help reduce cholesterol levels and the incidence of many diseases.
Studies of populations whose diets are high in fiber have shown that they have a lower incidence of colon cancer and other gastrointestinal diseases. Because it is indigestible carrying cellulose fiber away many toxins and harmful byproducts produced by the body.
Carbohydrates in the diet
Although it is important to get adequate amounts of carbohydrates in the diet it is also important that they’re the right type. Many of the foods that Americans eat are loaded with empty calories” or foods that are high in fat and sugar and low in fiber.
To maintain an ideal weight and ensure your body gets the fuel and fiber it needs it is important to eat a diet which is a mix of fruits vegetables and grains-all good sources of carbohydrates. For a balanced diet add an appropriate amount of fat and protein using the USDA Food Pyramid as a guide.”
