Discovering the Longevity Teas of the Blue Zones
Centenarians often share surprisingly simple lifestyle habits, and a regular tea ritual is one of the most consistent. The answer to what tea do centenarians drink varies by region, but the common thread is a preference for antioxidant-rich, natural infusions. From the floral green teas of Okinawa to the wild herbal blends of Ikaria, these beverages are much more than a drink; they are a daily dose of wellness intertwined with social and cultural traditions.
Okinawan Green Tea and Turmeric
In Okinawa, Japan, a renowned Blue Zone, a special blend of green tea infused with turmeric is a daily staple. This tea, known as shan-pien or "tea with a bit of scent," is rich in beneficial compounds. The base, green tea, is packed with catechins, powerful antioxidants that combat cell damage and inflammation. One specific catechin, EGCG, is particularly noted for its potential anti-cancer and anti-aging properties. Turmeric, the other key ingredient, is a well-known anti-inflammatory and potent antioxidant. Okinawans frequently consume this tea throughout the day, often filling a jar to sip on continuously, a habit linked to lower rates of heart disease, stroke, and certain cancers.
Ikarian Herbal Infusions
The Greek island of Ikaria, another Blue Zone hotspot, is famous for its inhabitants' long, healthy lives. The centenarians here regularly sip herbal teas made from local, wildcrafted herbs. These traditional brews often include a combination of:
- Rosemary: Known for its antioxidant properties and potential to improve cognitive performance.
- Sage: Often used to aid cognitive function and alleviate stress-related insomnia.
- Dandelion: A natural diuretic rich in vitamins A, C, and K, along with minerals like zinc and iron.
- Wild Marjoram: Prized for its antimicrobial and antioxidant effects.
- Mint (Fliskouni): Aiding digestion and offering a refreshing flavour.
These simple, local brews are consumed mindfully, often with family and friends, reinforcing social bonds and reducing stress.
Sardinian Milk Thistle Tea
In the mountainous Barbagia region of Sardinia, centenarians are known for consuming milk thistle tea, alongside their moderate consumption of local Cannonau red wine. Milk thistle is known to support liver health, which is vital for detoxification. The combination of a healthy plant-based diet, daily movement, and these specific beverages likely contributes to the region's high number of centenarians. Like the other Blue Zone teas, the Sardinian tea is simple, natural, and integrated into a daily rhythm of relaxation and social connection.

How Tea Consumption Contributes to Longevity
Regardless of the specific variety, the regular consumption of tea, especially green and certain herbal types, is consistently linked to a longer, healthier life. The key mechanisms include:
- Antioxidant Power: Tea is rich in plant compounds called polyphenols (including catechins and theaflavins) which act as powerful antioxidants. These compounds help neutralize free radicals, unstable molecules that can damage cells and accelerate aging.
- Heart Health: Studies associate habitual tea drinking with a lower risk of cardiovascular diseases, including heart attack and stroke. This is attributed to tea's ability to improve blood vessel function and lower cholesterol.
- Anti-Inflammatory Effects: Chronic inflammation is a significant driver of age-related diseases. Many teas, particularly green and Ikarian herbal blends, possess potent anti-inflammatory properties.
- Cognitive Function: Certain teas contain compounds like L-theanine (in green tea), which works with caffeine to improve focus and attention. Furthermore, antioxidants in tea are thought to protect brain cells from age-related decline.
- Gut Health: The polyphenols in tea can promote the growth of beneficial gut bacteria, contributing to a healthy microbiome, which is increasingly linked to overall health and longevity.
While the specific tea may differ, the shared habit among centenarians is the consistent, mindful incorporation of natural, antioxidant-rich teas into their daily lives. The specific blend often reflects local resources and traditions, making it a sustainable and culturally embedded part of their longevity strategy. The takeaway isn't to drink one specific brew, but rather to adopt a daily habit of consuming a healthy, plant-based tea as part of a low-stress, community-oriented lifestyle.
Conclusion: The Common Thread in Centenarian Teas
There is no single "magic" tea that centenarians drink, but rather a consistent pattern of consuming regional, plant-based infusions rich in antioxidants. From the green tea with turmeric in Okinawa to the herbal brews of Ikaria and the milk thistle tea of Sardinia, these beverages are a cherished daily ritual in the world's longest-living communities. They contribute to longevity by supporting heart health, reducing inflammation, boosting cognitive function, and aiding digestion, all while being a part of a slow, mindful lifestyle. Embracing this habit by enjoying your own locally-inspired or favorite antioxidant-rich tea can be a flavorful step toward a longer, healthier life.

Frequently Asked Questions
Is green tea the best tea for longevity?
While green tea is consistently cited for its high antioxidant content and health benefits, other varieties like black and herbal teas also offer significant advantages. The best tea is one that is consumed regularly as part of a healthy, balanced lifestyle.
What are catechins, and why are they important?
Catechins are a type of flavonoid and potent antioxidant found in high concentrations in green tea. They help prevent cellular damage from free radicals and are linked to a lower risk of heart disease, stroke, and certain cancers.
Do I need to drink wildcrafted herbal tea like the Ikarians?
No, while wildcrafted herbs are integral to the Ikarian tradition, the core takeaway is consuming fresh, natural, and antioxidant-rich ingredients. You can achieve similar benefits with high-quality, organic herbal teas readily available in stores.
Can adding milk or sugar to tea counteract its health benefits?
Adding milk to black tea may slightly counteract some beneficial vascular effects, although some studies suggest the effect is minimal. Adding excessive sugar, however, can introduce unhealthy calories and lead to weight gain, which increases the risk of chronic diseases.
How much tea should I drink for longevity?
Studies have linked habitual tea consumption of three or more cups per week to a longer, healthier life. Some studies suggest even greater benefits with consistent, daily consumption.
What makes Blue Zone teas different from store-bought tea?
The primary differences are the freshness and local origin of the ingredients, particularly with the herbal teas. However, many high-quality, store-bought teas can provide similar antioxidant and health benefits, especially if they are minimally processed.
Are there any risks to drinking a lot of tea?
Drinking excessive amounts of very hot tea may increase the risk of certain cancers, so allowing it to cool is recommended. For most people, moderate tea consumption is safe and beneficial, but individuals sensitive to caffeine should opt for herbal or decaffeinated versions.
