The Blue Zones — regions with exceptionally high life expectancy and quality of life — are coming under increasing pressure. Globalization, cultural change and the spread of fast food are threatening traditional lifestyles in regions such as Okinawa (Japan), Sardinia (Italy) and Nicoya (Costa Rica). Only the Adventist community in Loma Linda, California, has shown remarkable resistance to these influences so far.

‍

The loss of traditional habits:

• ‍Okinawa: Once known for an exceptionally high number of centenarians, Okinawa is losing its blue zone status. The younger generation is increasingly consuming fast food, which leads to more obesity, diabetes and other chronic diseases.

• ‍Sardinia and Nicoya: Here too, processed foods and a less active lifestyle are displacing health-promoting traditions.

• ‍Loma Linda: Adventists in California largely maintain their health practices as their religious values strongly promote healthy lifestyles and community bonding.

‍

Timeless principles of the Blue Zones:

Despite the challenges, the basic principles of these regions remain relevant:

• Nutrition: The focus is on vegetables, legumes, whole grains and low-processed foods.

• Movement: Regular, natural physical activity is essential.

• ‍Social connections: Strong family and community networks promote wellbeing.

• The meaning of life: A clear life purpose and stress-reducing routines contribute to longevity.

‍

Adapting to Modernity:

Developments in the Blue Zones show how difficult it is to preserve traditional habits in a globalized world. Yet initiatives such as the Blue Zones Project proved that these principles can also be applied in modern cities, for example through urban planning measures for better movement opportunities and the promotion of social networks.

Conclusion:

The original Blue Zones are changing, but the underlying principles are timeless. If people and communities integrate these lessons into their everyday lives, they can also benefit from the health benefits in modern societies — regardless of whether the original regions maintain their role models.
