Miracle Noodle from Japan Boasts Zero Carbs, Zero Calories

The noodles, which come in lots of familiar shapes such as spaghetti, angel hair, and fettuccini, are made of water and fiber from a plant called konjac yam instead of from wheat flour. They are naturally calorie- and carb-free, because the fiber they contain is not absorbed by the body. Tofu shirataki, a type made from soybeans and yam flour has about 20 calories and three grams of carbohydrates per serving.
