I buy the shirataki noodles that are made from konjac glucomannan fiber (not oat fiber), calcium hydroxide and purified water.. This is pure soluble fiber with 0 net carbs since soluble fiber does not get digested but is said to feed one's gut microbes (a good thing). These are the same as the ones Meme buys just different words used to name the same ingredients. These are the traditional Asian shirataki noodles. I really know nothing about the oat fiber noodles. I just have always bought the ones with glucomannan
