This health report explores the nutritional benefits of sweet potatoes, an ancient superfood originating from South America approximately 4,500 years ago. The segment highlights how this crop, unrelated to the common white potato, is gaining renewed global interest, particularly in Japan, where it is linked to longevity. A medium sweet potato can give you some manganese, iron, vitamin C, and B6 and calcium, plus 12% of your daily potassium and 34% of your daily copper needs. Additionally, the presence of a compound called yarapin is cited for its digestive benefits. The report concludes with practical advice on selecting firm, odourless produce and its versatility in both sweet and savoury dishes, making it a superior alternative to traditional fries for health-conscious viewers.
