Yacon is a South American root vegetable related to North American Jerusalem Artichokes and to sunflowers.
The root of yacon is considered the world's richest natural source of FOS (Fructooliosaccharides). Most other roots and tubers store carbohydrates as starch - a polymer of glucose. Yacon stores carbohydrate as FOS - a polymer composed mainly of fructose.
