What Blue Zones Teach Us About Living Longer

The Big Five

Blue Zones are five regions in the world where people live significantly longer, healthier lives. These areas—Loma Linda (California), Ikaria (Greece), Okinawa (Japan), Nicoya (Costa Rica), and Sardinia (Italy)—share a lifestyle that promotes longevity, vitality, and well-being.

What Makes Blue Zone Living Unique?

Residents of Blue Zones share 9 key habits that support long life and vibrant health:

Daily Movement: Staying active naturally—walking, gardening, or doing housework.

Sense of Purpose: Living with meaning adds up to 7 years to life expectancy.

Stress Management: Relaxation, social connection, and good sleep reduce harmful inflammation.

Mindful Eating: The “80% Rule” helps avoid overeating. The largest meal is eaten earlier in the day.

Mostly Plant-Based Diet: Rich in beans, veggies, and whole grains. Meat is limited and portions are small.

Moderate Alcohol: A glass of wine with food and friends is common (except in Loma Linda).

Strong Social Circles: Deep friendships, family ties, and faith-based community are essential.

Family First: Caring for elders and prioritizing family relationships promotes mental and physical health.

Supportive Networks: Positive peer influence encourages healthy choices.

Daily Movement

Staying active naturally

As a physician raised in the only Blue Zone in the U.S., I’ve seen firsthand how lifestyle and nutrition contribute to long healthy lives. But as a kidney stone specialist living there, I’ve noticed a surprising trend; many health-conscious patients were developing kidney stones, often while taking daily multivitamins.

Research revealed the problem; ingredients contained in the vitamin, specifically vitamin C, convert to oxalate and raise stone risk. Yet no multivitamin existed without it.

That’s why I created C-ERO, a complete multivitamin designed to support health while avoiding ingredients known to increase your risk of forming kidney stones.
