All forms of carbohydrates are made with sugar molecules. Carbohydrates were once broken into categories according to the complexity of their molecules, or simple carbohydrates and complex carbohydrates, with the complex variety being much preferred for athletes and others on healthy diets. Now, however, it’s been widely acknowledged that the proper breakdown of carbohydrates doesn’t fall into two clean-cut categories.

Okay, but what type of carbs should the athlete be eating? The reason carbs have a bad reputation is because there are lots of low-quality sources out there, in the form of junk foods and other convenience foods that don’t offer any real nutrition – people fill up on them and pack on the pounds, but are still starving for nutrients. Over consumption of simple sugars (mono and disaccharides), like those found in candy and soda, has also been linked to the onset of type 2 diabetes and obesity. These types of carbs have a high glycemic index, which means they cause your blood sugar to rise rapidly and then eventually crash. The exception to the rule is the simple sugar found in fruits. Because fruits contain fiber, vitamins, minerals, anti-oxidants and other goodies, they generally prevent the sugars from being absorbed so rapidly in your system, so you don’t get that crash.
