There's nothing wrong with starch (a complex carbohydrate of plant origin), nor its metabolization into sugar in the body. Starch, for example, is a polymer of glucose units and is typically broken down to glucose. The most important carbohydrate is glucose, a simple sugar (monosaccharide) that is metabolized by nearly all known organisms. Doctors and scientists once believed that eating complex carbohydrates instead of sugars would help maintain lower blood glucose. Numerous studies suggest, however, that both sugars and starches produce an unpredictable range of glycemic and insulinemic responses. https://en.wikipedia.org/wiki/Carbohydrate_metabolism https://en.wikipedia.org/wiki/Carbohydrate_metabolism
