It’s true. A carbohydrate-rich diet can inflate appetite and girth. Low-carb diets do promote short-term weight loss, but are accompanied by some severe dangers. So what should you do? The truth is, you can have your carbs and eat them too—you just have to know how to choose them.|
The Truth about Carbohydrates
All carbohydrates are not created equal.
Carbohydrates are the body's ideal fuel for most functions. They supply the body with the energy needed for the muscles, brain and central nervous system. In fact, the human brain depends exclusively on carbohydrates for its energy.
Carbohydrates are found in fruits, vegetables, beans, dairy products, foods made from grain products, and sweeteners such as sugar, honey, molasses, and corn syrup.
The body converts digestible (non-fiber) carbohydrates into glucose, which our cells use as fuel. Some carbs (simple) break down quickly into glucose while others (complex) are slowly broken down and enter the bloodstream more gradually.
During digestion, all carbohydrates are broken down into glucose before they can enter the bloodstream where insulin helps the glucose enter the body’s cells. Some glucose is stored as glycogen in the liver and muscles for future use, like fueling a workout. If there is extra glucose, the body will store it as fat.
There are basically three types of carbohydrates:
Simple carbohydrates are composed of 1 or 2 sugar units that are broken down and digested quickly.
Recent research has shown that certain simple carbohydrate foods can cause extreme surges in blood sugar levels, which also increases insulin release. This can elevate appetite and the risk of excess fat storage.
Complex carbohydrates (also referred to as starch) are made up of many sugar units and are found in both natural (brown rice) and refined (white bread) form. They are structurally more complex and take longer to be broken down and digested.
Complex carbohydrate foods have been shown to enter the blood stream gradually and trigger only a moderate rise in insulin levels, which stabilizes appetite and results in fewer carbohydrates that are stored as fat. Unrefined or ‘whole grain’ carbohydrates found in products like brown rice, whole wheat pasta and bran cereals are digested slowly. They contain vitamins, minerals and fiber which promote health. Fiber and nutrient-rich vegetables, fruits and beans which are carbohydrates also have many important functions for the body and are important for good health.
Indigestible carbohydrates are also called fiber. The body is unable to breakdown fiber into small enough units for absorption. It is therefore not an energy source for the body but does promote health in many other ways.
