Although you should limit added sugars in your diet, you don't need to limit natural sugars in food, as these sugars are found along with fiber, vitamins and minerals. Potatoes contain three main types of sugars: fructose, sucrose and glucose.
Baking potatoes are relatively high in starch and it is called amylose starch. Boiling potatoes are low in starch and it is called amylopectin. This pectin (just as with fruit for jams) is what holds the potato together when boiling or in soup and stews.
