The Centenarian Secret: Foods Doctors Eat Every Day for Maximum Healthspan

27. Sunchokes (Jerusalem Artichokes): The Unique Prebiotic Dynamo

Sunchokes, or Jerusalem artichokes, are a root vegetable highly valued by gut health experts for their massive concentration of inulin—a specific type of prebiotic fiber that feeds beneficial bifidobacteria. While other foods list prebiotic fiber, sunchokes provide an exceptional, non-starchy form. A healthy gut microbiome is directly linked to robust immunity, reduced chronic inflammation, and improved metabolic balance—the core pillars of healthspan. Enjoy sunchokes raw, sliced thinly, or cooked like potatoes. This addition offers a unique, foundational way to optimize the gut environment for long-term systemic health.

28. Potatoes (Skin On): The Potassium and Vitamin C Antioxidant

Potatoes, when consumed with the skin, are a highly accessible superfood and a premier source of two compounds crucial for healthspan. First, they are exceptionally rich in Potassium, a mineral essential for balancing sodium and regulating blood pressure—a major risk factor in aging. Second, potatoes are a surprising source of Vitamin C, a powerful antioxidant that helps synthesize collagen and protect cells from oxidative stress. When baked or boiled with the skin intact, the potato's nutrient-rich profile provides filling, sustained energy along with the minerals and antioxidants needed to maintain cardiovascular and cellular function cheaply and effectively. This pantry staple is a simple, potent tool against age-related vascular stiffness, proving that basic foods can deliver elite nutrition.
