Simple carbohydrates "without nutritional value" These are the ones we should avoid at all costs. These carbohydrates are absorbed faster in our body, in addition, generally the caloric concentrations of the same are quite high, which causes them to accumulate more quickly in adipose tissue (mainly in the abdominal area). In addition they usually contribute little or no vitamins and minerals. Examples of these would be any type of sweets, chocolates, bakery products, among other combinations of refined sugars.
