Famous for its role in shirataki noodles, konjac root is packed with glucomannan, a powerful prebiotic fiber. It’s virtually calorie-free but swells in the gut, making you feel full while quietly feeding your microbiome. Use shirataki noodles as a pasta substitute or blend konjac powder into smoothies for a thicker texture. It’s a stealthy gut booster that doesn’t alter flavor—perfect for those who want results without effort.

Despite the name, tigernuts are tiny root vegetables with a chewy texture and naturally sweet, nutty flavor. They're rich in resistant starch and promote the growth of gut-friendly bacteria. You can eat them raw, soak them for softness, grind them into flour, or enjoy tigernut milk as a dairy-free alternative. Their versatility, plus benefits for blood sugar and digestion, make tigernuts a sleeper hit in the world of gut health.
