The Role of Tea in Blue Zone Lifestyles
While diet, community, and daily movement are cornerstone habits of Blue Zone inhabitants, the routine of drinking tea is a significant, often overlooked, element of their longevity. Rather than consuming sugary drinks, people in these areas hydrate frequently with water and tea throughout the day, a practice that delivers a steady stream of antioxidants and other beneficial compounds. The types of tea vary considerably depending on the Blue Zone's geography and culture, drawing on native plants and long-standing traditions. From the ancient tea leaf blends of Okinawa to the wild-crafted herbs of the Mediterranean, each tea offers specific health advantages.
Okinawan Green Tea and Turmeric
The people of Okinawa, Japan, famously drink copious amounts of green tea, often spiced with jasmine and turmeric. This beverage, known as “shan-pien” or “tea with a bit of scent,” is a daily staple, consumed for decades or even a century. The health benefits are widely supported by scientific research:
- Green Tea: Packed with powerful antioxidants called catechins and polyphenols, green tea is linked to a reduced risk of heart disease, stroke, cancer, and cognitive decline. It also contains L-theanine, an amino acid that promotes relaxation and improved mood, counteracting potential jitters from caffeine.
- Jasmine: The addition of jasmine provides a pleasant aroma and additional antioxidants.
- Turmeric: A potent anti-inflammatory and antioxidant, turmeric is a key ingredient in Okinawan cooking and tea, supporting overall health and fighting chronic inflammation.
The Herbal Brews of Ikaria
On the Greek island of Ikaria, herbal tea is a daily ritual, often brewed with freshly picked herbs from the wild. This tradition is deeply connected to the island's natural environment. Researchers who have analyzed these wild-grown herbs found that they contain anti-inflammatory and mild diuretic properties, which can help lower blood pressure. Ikarians typically consume their teas plain or sweetened lightly with local honey.
Some of the common herbs used in Ikarian tea include:
- Rosemary: Known for its antioxidant properties and cognitive support.
- Wild Sage: A traditional remedy used for cognitive function, immune support, and fighting colds.
- Oregano: Prized for its antimicrobial and antioxidant effects.
- Dandelion: A natural diuretic rich in vitamins A, C, and K, used for immune-boosting and cardiovascular health.
- Wild Mint: A refreshing herb that aids digestion and provides antioxidants.
Sardinian Milk Thistle Tea
In the mountainous region of Sardinia, Italy, the centenarians prefer milk thistle tea, a native wild plant. For centuries, locals have believed this tea can “cleanse the liver,” and modern science is investigating its principal active ingredient, silymarin, for its antioxidant and potential anti-cancer effects. Milk thistle contributes to the Sardinian diet, which is also rich in goat's and sheep's milk products, fava beans, and low-glycemic barley bread.
Nicoyan Herbal Teas
The Nicoya Peninsula in Costa Rica, another Blue Zone, also embraces herbal teas made from native plants. Inspired by the gardens of centenarians, these teas feature locally sourced ingredients with significant health benefits.
- Guava Leaf: Has a mild, soothing taste and is rich in antioxidants, traditionally used for digestion.
- Burbark and Spearmint: A blend used to alleviate cold symptoms and aid stomach health.
- Lippia Alba and Hibiscus: A popular combination known for being rich in micronutrients.
- Maya Nut and Cinnamon: Offers a nutty, comforting flavor profile with antioxidants, calcium, and essential amino acids.
The Tea Tradition of Loma Linda
While the Loma Linda, California, Blue Zone, inhabited largely by Seventh-Day Adventists, is known for its vegetarian diet and abstinence from alcohol, tea consumption is also part of their hydration habits. Although specific teas are not as highlighted as in other Blue Zones, the practice of drinking tea throughout the day, in addition to water, is consistent with the hydrating habits observed across all regions.
