In general, bad carbs are those that rely on sugars, refined grains and other foods with a high glycemic index. Complex carbohydrates tend to be classified as good carbs because they take a longer time to digest than simple carbohydrates. Because of this, they release energy into the body at a consistent rate through the day, Everyday Health explains.
The glycemic index is a measurement of how quickly the body's blood sugar rises after ingesting a certain food compared to the rise in blood sugar resulting from eating pure sugar. Foods with a lower glycemic index tend to be good carbs such as whole grains, vegetables, fruits and other high-fiber foods, according to Everyday Health.
Bad carbs, on the other hand, include sugars, sodas, syrups, pastries and candy. In addition, white rice, non-whole-grain pasta and white bread are bad carbs with a high glycemic index, reports Everyday Health. Potatoes are also considered a source of bad carbs, even though they are vegetables.Learn more about Nutritional Content
