"Yacon" (Smallanthus sonchifolius), commonly called Peruvian ground apple, is a sweet-tasting root vegetable native to the Andean regions of South America. Traditionally consumed fresh for its crisp texture, yacon provides abundant fructooligosaccharides (FOS) and soluble fiber. Acting as prebiotics, its naturally occurring fibers promote gut flora balance, aiding digestion and nutrient absorption. This fiber content also contributes to stable blood sugar and appetite control through metabolic support. Yacon's distinct nutritional profile explains its enduring presence in traditional Andean diets.
