The Okinawa Diet is a traditional eating pattern from Okinawa, Japan, known for promoting longevity and health. Okinawans, especially the older generations, have some of the highest life expectancies in the world, and much of this is attributed to their unique diet and lifestyle.
π₯ Core Principles of the Okinawa Diet:
Low in Calories, High in Nutrients
Okinawans traditionally eat fewer calories than mainland Japanese but receive more vitamins, minerals, and antioxidants.
Plant-Based Emphasis
~80% of the diet is plant-based, with an emphasis on:
Sweet potatoes (especially purple and yellow)
Leafy greens (like bok choy, mustard greens)
Seaweed (kombu, wakame)
Soy foods (tofu, miso, edamame)
Minimal Meat and Dairy
Meat is eaten sparingly, usually pork, and often stewed or boiled.
Dairy products are almost non-existent traditionally.
Fish as a Protein Source
Fish is consumed moderately, rich in omega-3 fatty acids.
Limited Grains and Rice
Unlike mainland Japan, white rice is less central. More reliance on sweet potatoes as a staple.
Herbs and Medicinal Plants
Turmeric and goya (bitter melon) are common and believed to have anti-aging effects.
Low Sugar and Processed Food
Desserts and processed foods are rare; traditional sweets use minimal sugar.
Hara Hachi Bu (θ

This is the practice of eating until 80% full—a form of mindful caloric restriction.
