What the Blue Zone is Telling Us About the Benefits of Extra Virgin Olive Oil

‘People in blue zones walk, garden and bike as part of their daily lives. They are close to friends and family, have a purpose in life, handle stress well, and are often members of a social or religious group. They eat a plant-based diet and stop eating before they are full.’

What are "Blue Zones"?

The "Blue Zones" are regions in the world where people live significantly longer and healthier lives than average. Researchers have identified several Blue Zones, including Sardinia (Italy), Okinawa (Japan), Loma Linda (California, USA), Nicoya Peninsula (Costa Rica), and Ikaria (Greece).

One key finding from studies of these regions is the positive impact of diet on longevity and health, particularly the Mediterranean diet, which often includes extra virgin olive oil as a staple.

Dan Buettner, who first brought blue zones into the public consciousness with his National Geographic articles and later books, doesn’t like to call the blue zone eating pattern a “diet.” Instead, it’s part of a healthy lifestyle, Buettner said, one that he believes anyone can copy, no matter where they live and eat — even in highly processed, food-obsessed cultures such as the United States.

“The blue zone eating pattern is 98% plant-based foods — whole food-based and high carbohydrate. But only complex carbs, not the simple carbs like salty snacks and candy bars and soda pop,” Buettner told CNN. “You say carbohydrates and people are horrified, but the healthiest foods in our food system are complex carbohydrates.”

A new report from Everydayhealth shows us just how important a healthy diet with healthy fats like olive oil is in contributing to longevity and reduced rates of chronic illness.

Benefits of Extra Virgin Olive Oil

1. Rich in Healthy Fats: Extra virgin olive oil is high in monounsaturated fats, which are heart-healthy fats. These fats can help reduce LDL (bad) cholesterol levels and increase HDL (good) cholesterol.

2. Anti-Inflammatory Properties: Olive oil contains compounds like oleocanthal and oleuropein that have anti-inflammatory effects. Chronic inflammation is linked to many age-related diseases, so reducing inflammation can contribute to longer, healthier life.

3. Antioxidant-Rich: It is packed with antioxidants, including vitamin E and polyphenols, which help combat oxidative stress and protect cells from damage. This can reduce the risk of chronic diseases and support overall health.

4. Supports Brain Health: Some studies suggest that extra virgin olive oil may help protect against cognitive decline and neurodegenerative diseases such as Alzheimer’s. The antioxidants and anti-inflammatory compounds in olive oil play a role in brain health.

5. Improves Digestive Health: Olive oil can promote healthy digestion and may help reduce the risk of certain digestive disorders. It also has mild laxative effects that can aid in regular bowel movements.

Mediterranean Diet and Longevity

The Mediterranean diet, commonly followed in Blue Zone regions like Ikaria and Sardinia, emphasizes:

1. High Consumption of Plant-Based Foods: The diet is rich in fruits, vegetables, legumes, nuts, and whole grains, providing essential nutrients and fiber.

2. Moderate Intake of Fish and Poultry: Fish and poultry are consumed regularly but in moderate amounts, providing high-quality proteins and omega-3 fatty acids.

3. Low Intake of Red Meat and Sweets: Red meat and sweets are eaten sparingly, which helps reduce intake of unhealthy fats and sugars.

4. Olive Oil as a Primary Fat Source: Olive oil is used as the main source of dietary fat, enhancing flavor and providing health benefits.

5. Social and Lifestyle Factors: The Mediterranean lifestyle includes regular physical activity, strong social connections, and stress reduction, all of which contribute to longevity and well-being.

Key Takeaways

The Blue Zones research suggests that incorporating extra virgin olive oil into a predominantly plant-based diet, like the Mediterranean diet, can have significant health benefits and contribute to a longer, healthier life. The combination of healthy fats, antioxidants, and anti-inflammatory properties of olive oil, along with a balanced diet and active lifestyle, creates a powerful formula for promoting longevity and well-being.
