Carbohydrates are a necessary component of good nutrition. 45-65% of our diet should comes from carbs. Carbs are made up of carbon, hydrogen, and oxygen molecules. There are two groups of carbohydrates. There are simple and complex carbohydrates. In simple carbs there are Monosaccharides and Disaccharides. Monosaccharides consist of Glucose, Galactose, and fructose. Disaccharides consist of Maltose, Sucrose, and Lactose. Complex carbs are Glycogen, Starch, and Fiber. Not all foods with carbohydrates are particularly healthy. In fact, when you do not consume enough carbs your body is forced to search for a new source of energy. That is considered malnutrition. When you eat to many carbs, the body does not know what to do with the extra energy so it stores it as fat. Carbohydrates are great in moderation.
