Why It Matters for Longevity

Used in several Longevity Diet soups and stews; provides iron (2 mg per medium, 11% DV), magnesium (43 mg per 3.5 oz baked with skin, 11% DV), vitamin C (17 mg per medium baked, 28% DV), and calcium (62 mg per cup baked with salt, 6% DV). Sweet potato is a top vitamin A source (1403 mcg RAE per whole baked in skin, 561% DV). Starchy vegetable; sweet potato exceptionally rich in beta-carotene (vitamin A provitamin). Cooling cooked potatoes significantly increases resistant starch (RS2/RS3), lowering glycemic response by up to 40%; meal prep strategy relevant to longevity diet (PubMed) Sweet potato anthocyanins and beta-carotene demonstrate anti-inflammatory and antioxidant effects; associated with reduced oxidative stress markers in interventional studies (PubMed)
