Carbohydrates are the main source of energy for the body. In particular, the brain and the nervous system are affected most by this source of energy. Carbohydrate molecules are made of carbon, hydrogen and oxygen. After digestion occurs, carbohydrates are broken down (metabolized) and processed by the liver and turned into blood sugar called glucose. These sugars provide the energy to the body that aid with activities such building stronger organs and blood regualtion and type. Carbohydrates are absorbed into the body by eating sugars from fruits or from grains.
There are two types of carbohydrates: Simple carbohydrates and complex carbohydrates. Simple carbs may come from fruit such as apples, blackberries, cherries, grapefruit and oranges. Complex carbs come from starchy foods such as potatoes and beans, as well as breads and pastas which are made of grains.
Nutritionists suggest that grains and other foods creating carbohydrates occupy upwards of 50% percent of the diet intake or the average person. Carbohydrates are good for the body and contribute to intestinal functioning as well as providing important energy to the brain. The sugars created by the ingestion of carbohydrates have no ill effects on the body, and carbohydrate consumption can actually aid in weight control. Insulin works directly with the glucose formed by carbohydrates to regulate the body's functioning for weight gain.
