Okinawa, a group of 161 Japanese islands, boasts the world’s longest living people. They enjoy the lowest rates of heart disease, stroke, and cancer (the three leading killers in the United States). The average Okinawan woman lives to the age of 86 and the average man to 78, compared with 79 and 72, respectively, in the United States. They typically die of natural causes rather than disease. Okinawans eat an average of seven servings of vegetables and fruits daily, along with seven servings of grains, two servings of soy products, omega-3 fatty acid-rich fish several times per week, very few dairy products, and little meat.
