Not all carbs are create equal. One doesn't 'need' sugar to live.
Actually, they are. There's some debate about how fast they are absorbed and the short term effects on blood sugar. But after the stomach gets a hold of sugars and starches, it is all the same. Fear of white sugar is a silly superstition. Large helpings of carbs are not good for weight control. But other than maybe the effect on teeth, the finest organic pasta is no different than a spoonfuls of beet sugar.
