Bad carbs include refined flours, starches, processed foods and added sugars, notes WebMD.

Bad carbs and a lack of adequate fiber in the diet can create a host of medical problems such as heart disease and colon cancer if continued for too long.

Good carbs are found in vegetables, fruits, legumes and whole grains. They can help to slow the release of glucose into the bloodstream, manage cholesterol levels and help a person feel full longer. It is recommended that good carbs comprise between 45 and 65 percent of a person's daily caloric intake, especially as a fiber source.
