Seaweed and kelp noodles are very low-carb noodles made from kelp (a type of seaweed). They contain little to no digestible carbohydrates and are suitable for low-carb, keto, and diabetic-friendly eating. Kelp noodles have a neutral flavor and firm texture that works well in stir-fries, salads, and noodle dishes.
