What if the secret to a long, healthy life was right on your plate? Around the world, centenarians—people who live to be 100 or older—share a common set of eating habits that contribute to their extraordinary longevity. Scientists have identified key regions, known as “blue zones,” where people consistently live longer and healthier lives. These areas include Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece; and Loma Linda, California. So what do they eat? Here’s a breakdown of the five most popular foods that boost longevity.
1. Legumes: The Power of Plant Protein
Legumes—beans, lentils, and chickpeas—are a staple in almost every blue zone. They’re packed with fiber, protein, and essential vitamins that help regulate blood sugar, lower cholesterol, and support gut health.
Expert opinion: Dr. Valter Longo, a longevity researcher and author of The Longevity Diet, says, “A diet rich in legumes is one of the most powerful tools for preventing chronic disease and extending your lifespan.”
2. Leafy Greens: Natural Antioxidants
Spinach, kale, and Swiss chard are packed with vitamins, minerals, and antioxidants that reduce inflammation and protect against disease. In Okinawa, locals eat a variety of bitter greens, such as goya (bitter melon), which is believed to help regulate blood sugar.
Centennial quote: “I eat my greens every day, just like my mother did. She lived to be 104,” shares Maria Rossi of Sardinia.
3. Nuts: A Daily Handful for Heart Health
Almonds, walnuts, and pistachios are rich in healthy fats, protein, and fiber. In Loma Linda, where a high percentage of Seventh-day Adventists follow a plant-based diet, daily nut consumption has been linked to longer life expectancy.
The scientific side: A Harvard study found that people who eat a handful of nuts daily have a 20% lower risk of premature death.
4. Whole Grains: A Sustained Source of Energy
Whole grains, such as barley, brown rice, and sourdough bread, are staples in longevity hot spots. These grains provide sustained energy, improve digestion, and support heart health.
Okinawan wisdom: “Eat rice with vegetables and your body will thank you,” says 102-year-old Masako Tanaka.
5. Olive oil: liquid gold for longevity
In Ikaria and Sardinia, olive oil is an essential part of the daily diet. It’s packed with monounsaturated fats and polyphenols that support brain function and reduce inflammation.
A nutritionist’s insight: “Olive oil is a major reason why the Mediterranean diet is one of the healthiest in the world,” says Dr. Michael Greger, a nutrition expert and author of How Not to Die.
The Longevity Lifestyle
In addition to food, the long-lived also have common life habits: regular physical activity, strong social connections, and a sense of purpose. Their diet is not about restrictions, but about nourishing their bodies with whole, natural foods.
