In regions of the world known as Blue Zones, where populations live exceptionally long, healthy lives, diet is a key factor in their longevity. The principles governing these eating habits, which include a predominantly plant-based intake, extend to midday meals, but what do people in blue zones eat for lunch specifically?

Quick Summary

The midday meals in Blue Zones are primarily plant-based, featuring legumes, whole grains, and a variety of seasonal vegetables prepared simply. Lunch is often a hearty, nutrient-dense dish like a bean soup, vegetable stew, or a grain bowl, emphasizing moderate portions and high-fiber ingredients.

Key Points

• Regional Diversity: Meals vary by location—from Nicoyan gallo pinto to Ikarian lentil soup—but share a focus on locally sourced, whole foods.

• Moderate Portions: Following the hara hachi bu tradition, residents eat until 80% full, preventing overconsumption.

• High-Fiber Content: Beans, whole grains, and vegetables provide abundant fiber, promoting digestive health and sustained energy.

Core principles of a Blue Zone lunch

The midday meal in Blue Zones isn't just about what's on the plate; it’s about a mindful and wholesome approach to eating. Adhering to the overarching principles of the Blue Zone diet, lunches prioritize a "plant slant," featuring foods that are 95% plant-based. This means centering meals around beans, legumes, vegetables, and whole grains. Meat is reserved for special occasions, and most dairy products are minimized or avoided. Emphasis is placed on whole, unprocessed ingredients that are often locally and seasonally sourced. The practice of hara hachi bu, or eating until 80% full, is also paramount, ensuring moderate portion sizes. These principles translate into simple yet incredibly nutritious and satisfying lunches across the different Blue Zone regions.

Across the world's five Blue Zones—Okinawa (Japan), Sardinia (Italy), Nicoya (Costa Rica), Ikaria (Greece), and Loma Linda (California)—specific ingredients are consistently featured in lunchtime meals.

Legumes and beans: These are the cornerstone of a Blue Zone diet and are a daily presence in lunch meals.

• Lentils and chickpeas: Common in the Mediterranean regions of Sardinia and Ikaria, forming the base of many soups and stews.
