Secret Superfoods You Walk Past Every Time You Go Shopping

41. Kudzu Root (Kuzu): The Digestive and Circulation Aid

Kudzu root, traditionally used as a powdered starch in Asian cuisine, offers unique benefits for digestive health and circulation. When dissolved in liquid and heated, it creates a thick, translucent jelly rich in isoflavones, notably puerarin. Puerarin is researched for its potential to improve blood flow and relax blood vessels, subtly benefiting cardiovascular health. More commonly, Kudzu acts as a potent prebiotic and demulcent, helping to soothe the digestive tract and support the growth of beneficial gut bacteria. Use Kudzu powder as a gluten-free thickener for soups, sauces, and gravies, or dissolve a teaspoon in warm water for a calming, gut-supportive evening drink.

42. Chicory Root (Ground/Brewed): The Concentrated Prebiotic

Chicory root is a highly concentrated source of inulin fiber, a potent prebiotic that dramatically outperforms most other sources. What it trains: This root vegetable, often dried and brewed as a coffee substitute, is almost pure fuel for beneficial bifidobacteria in the gut. Why it helps: By maximizing the health of the gut microbiome, chicory fiber supports superior nutrient absorption, enhances immune regulation, and improves metabolic efficiency. It is also linked to increased calcium absorption and reduced inflammation. How to use: Start slowly, as a sudden increase can cause digestive upset. Blend chicory root powder or brewed chicory coffee into smoothies, or use it as a binder in protein bars for a concentrated, accessible boost to gut health.
