Pho is known for its delicious broth, but this is where the healthy diner needs to exercise caution: the exact numbers vary widely depending on the recipe, but a standard bowl can easily supply thousands of milligrams of sodium.
Konjac glucomannan (KGM) is a water-soluble dietary fiber derived from the root of the Konjac plant. Konjac foods, also called Shirataki Nooldes In Japan, made from Konjac Glucomannan, are traditional Chinese foods with a history spanning over two thousand years.
Shirataki noodles come from a yam-like tuber called Devil's Tongue. Glucomannan starch is extracted from the tubers, then mixed with water and limewater to turn it into a substance called konnyaku. Konnyaku is then shredded into traditional shirataki noodles. Sometimes other ingredients are added into shirataki noodles, like soy, and you'll see them labeled tofu or with other flavors.
