Bad Carbohydrates Bad carbohydrates are the refined, highly processed carbohydrates from which most of the nutrients and fiber have been removed. White flour and refined sugar contained in many processed foods are primary examples of bad carbohydrates. The body has trouble processing these foods, and therefore, they do not digest
well. Simple starches and sugars throw off insulin production, causing fluctuations in blood glucose levels. Most foods that contain bad carbohydrates provide empty calories with little or no nutritional value. As a result, the body stores these extra calories in the cells as fat.
