Okinawa-Diet
The Japanese island of Okinawa is world-famous for its exceptionally high number of centenarians. Many experts attribute this phenomenon to the unique lifestyle and, above all, the traditional diet.
Why is the Okinawan diet healthy?
A central rule in the everyday life of Okinawans is: “Hara hachi bu”—only eat until you are 80% full. This principle prevents overeating and ensures a natural reduction in calories without causing real hunger. This keeps the body lighter, protects the metabolism, and stabilizes energy supply. The strength of this diet lies in its combination of plant diversity, nutrient-rich foods, and moderate calorie intake. It provides the body with plenty of fiber, antioxidants, and phytochemicals, which protect cells and reduce inflammation. At the same time, it keeps blood sugar and insulin levels in balance, which reduces the risk of age-related diseases such as diabetes and heart problems.
The results are evident in the everyday lives of the local people: Okinawans often remain active, mentally alert, and physically mobile into old age. Their diet is therefore considered one of the best examples of how conscious eating can slow down the aging process and ensure quality of life for decades to come.
What do you eat on the Okinawa diet?
Instead of lavish meals with meat or sugar, the focus is on simple, nutrient-rich foods: lots of vegetables, sweet potatoes as a staple food, tofu and other soy products, seaweed, and small amounts of fish. Meat, dairy products, and sweets, on the other hand, play hardly any role.
What are some typical dishes in the Okinawan diet?
- Imo dishes—especially dishes with purple sweet potatoes, which are traditionally the main source of carbohydrates, for example, steamed or simply as a side dish.
- Miso soup: usually with seaweed, tofu, and vegetables
- Goya Champuru – a classic stir-fry dish made with bitter melon, tofu, a little egg, and vegetables
- Vegetable dishes – often with cabbage, carrots, radishes, bamboo shoots, or pumpkin
