Okinawa, a stunning island off the coast of Japan, is celebrated worldwide for its extraordinary longevity and vibrant health among its residents. Jamie Oliver’s exploration of this remarkable place reveals fascinating insights into the Okinawan diet, daily routines, and superfoods that contribute to their long, healthy lives. If you’re passionate about cooking, easy recipes, and embracing food as medicine, Okinawa offers a treasure trove of inspiration.
The Morning Rituals: Exercise and Community
One of the secrets to Okinawa’s longevity isn’t just what they eat—it’s also how they move. Each morning, the island comes alive with a nationwide broadcast of radio exercise, a gentle workout designed to improve stretching and flexibility. People of all ages, from children to nonagenarians, gather in groups or exercise at home, performing these familiar routines learned since primary school.
This practice fosters not only physical health but also a strong sense of community. Regular exercise paired with social connection is a powerful combination for healthy aging. As Jamie observed, “They’re all incredibly flexible... touching their toes, spinning around. This has got to be amazing for old age and longevity.”
Tofu: Okinawa’s Beloved Superfood
When it comes to diet, Okinawans champion one food above all others: tofu. They consume more tofu than anywhere else in the world, and for good reason. Tofu is a nutritious, plant-based protein that fits perfectly into their low-meat diet. Jamie met Shigaro Nigado, a third-generation tofu artisan who still crafts tofu by hand, preserving traditional methods that enhance flavor and texture.
Shigaro’s process begins with dried soybeans ground into soya milk, which is then heated and coagulated with nigari—a natural coagulant made from Japanese sea salt. The result is fresh, silky tofu that Jamie described as “the best tofu I’ve ever had in my life.”
Shigaro produces two main types: a super soft silken tofu and a firmer block tofu pressed to remove excess liquid. Both varieties are staples in Okinawan cuisine and provide a rich source of protein that is low in saturated fat and supports heart health by lowering cholesterol.
Jamie noted, “If we’re talking about longevity and health, it’s impossible to ignore the role of tofu. It’s so prolific in their diet and such an incredible protein. This is something we should definitely get into our lives.”
Active Aging and the Birthplace of Karate
Okinawa’s longevity is also tied to an active lifestyle, and it’s famously the birthplace of karate. Jamie visited Senzei Haiga, a 74-year-old grand karate master, to learn about the martial art and its role in keeping Okinawans fit well into old age.
Karate here is more than a sport—it’s a lifelong practice that builds strength, discipline, and vitality. Senzei’s dojo was a testament to this, with black belts lining the walls and a spirit of perseverance in every movement. Even at his age, Senzei’s strength and energy are inspiring.
The Power of Sweet Potato and Plant-Based Eating
Contrary to what many expect, rice is not the staple food in Okinawa. Instead, the nutrient-dense sweet potato holds that honor. Due to frequent typhoons, rice cultivation is difficult, so sweet potatoes have become the island’s primary carbohydrate source. For decades, sweet potatoes—especially the purple and white varieties—accounted for over half of daily calories.
Sweet potatoes are a powerhouse vegetable, packed with vitamins, minerals, and antioxidants. Jamie enthusiastically recommends doubling your intake if you already enjoy them, or adding them to your diet if you don’t.
Food as Medicine: The Okinawan Philosophy
The Okinawans live by the philosophy of nushigushi, meaning “let food be your medicine.” This belief guides their diet and lifestyle choices, aiming to prevent illness before it starts. Jamie met Mister Shoy Kinjo, a 95-year-old who embodies this mindset through his extensive vegetable garden filled with healing plants like mint, chilies, mugwort, and especially goya (bitter melon).
Goya is a summer staple rich in vitamin C, essential for immune and nervous system health. Jamie tasted various goya dishes, including a local stir-fry called Goya Champuru, which beautifully showcases this unique vegetable.
Jamie emphasized, “This is what Okinawans do—they cook foods that are good for their body at the right time of year, embracing food as something that makes you feel great.”
Seaweed: The Overlooked Superfood of the Sea
Okinawa’s diet is also rich in seaweed, a nutrient-dense food that many Western diets overlook despite its abundance around coastal regions like the British Isles. Jamie met Tadashi Oshiro, a 58-year-old seaweed farmer, who introduced him to various seaweed types, especially mazuku, an Okinawan favorite.
Seaweed is packed with iron, vitamin B12, and other nutrients that support immune health. Just a small handful of dried seaweed contains as much iron as two bags of spinach, making it a potent dietary addition.
Tadashi’s 83-year-old mother, who still works alongside him, is living proof of seaweed’s health benefits. Jamie tasted seaweed tempura and fresh seaweed salad, both delicious and packed with flavor and nutrition.
As Jamie observed, “Seaweed is absolutely a cornerstone of their diet. If you can look this good at 83, seaweed is definitely something to look out for.”
