How Do Okinawans Eat Sweet Potatoes?
In Okinawa, purple sweet potatoes have long been a staple. Traditionally, they are steamed or boiled and eaten plain as part of daily meals. Instead of relying heavily on rice, Okinawans historically consumed sweet potatoes as their primary carbohydrate, pairing them with vegetables, miso soup, and small portions of fish.
They are also used in festive foods, such as steamed buns filled with mashed purple potato, or as fillings for pastries and cakes. In modern cooking, they’ve become a favorite ingredient in lattes, smoothies, and ice creams.
This reliance on sweet potatoes combined with a diet low in meat and rich in vegetables has contributed to Okinawans’ exceptional health and longevity.
