WebMD provides an article detailing the differences between good carbohydrates and bad carbohydrates, as well as a list of examples of both. Good carbohydrate sources are high in fiber and absorbed slowly by the body. Bad carbohydrate sources are refined and processed, removing much of the beneficial fiber.
Examples of good carbohydrate sources include whole grains, vegetables, fruits and beans, which all contain fiber. Fiber slows down nutrient absorption and may help regulate blood sugar levels, decreasing the risk of Type 2 diabetes. Examples of bad carbohydrate sources include sugars, white bread and white rice. While sugars are high in caloric energy, sugars do not provide fiber content.
