Ikaria, a small Greek island in the eastern Aegean, has long been recognised as one of the world's five "Blue Zones" – regions where residents enjoy notably longer lifespans and lower rates of chronic disease. With more than 8,000 full-time inhabitants, the island counts one in three residents living past the age of 90. Strong social ties, daily physical activity and routine napping are among the factors credited for this longevity, alongside a predominantly plant-based diet.
The traditional Ikarian eating pattern mirrors the wider Mediterranean diet, rich in fibre, healthy fats and nutrient-dense whole foods. Staples include nuts, grains, potatoes, legumes, vegetables and seeds, with olive oil as the primary added fat. Yogurt, cheese, fish, poultry and red wine are consumed in moderation, while red meat appears only a few times each month. This dietary approach has been linked to reduced risks of heart disease, stroke, diabetes, high cholesterol, obesity and high blood pressure.
Greek American chef Diane Kochilas, who splits her time between New York and Ikaria, explores this way of eating in her forthcoming cookbook, The Ikaria Way, published on 26 March. The book offers a "roadmap" for incorporating aspects of the island's cuisine into everyday life, with 100 plant-based recipes. Kochilas said she was inspired during a weeklong cooking class on the island when guests from Montana admitted they had never imagined plant-based food could be so satisfying and varied.
Beans feature prominently in the book, used in dishes such as lemony fava beans with artichokes, dried fava stew, and caramelised giant beans with turmeric and fennel. Kochilas highlights the health benefits of beans, noting that their soluble fibre attaches to cholesterol particles and flushes them out of the body. She also emphasises the importance of reducing stress, observing that many people accept high levels of stress that are "detrimental" and often self-created.
The Ikarian diet is not only healthful but also practical. Many residents still observe the Greek Orthodox Church's fasting calendar, abstaining from meat during periods such as Lent, which makes plant-based cooking a natural choice. Kochilas notes that the ingredients – including yogurt, dried fruits, honey, olive oil, nuts, fresh herbs and legumes – are widely available in most supermarkets, making the lifestyle accessible beyond the island.
