Tea is one of the most widely consumed beverages in the world, and for good reason. Not only is it delicious and refreshing, but it also has many health benefits that may contribute to a longer and better life. Here are some of the ways that tea can help you live longer, based on scientific research and the habits of people in the Blue Zones, regions of the world where people live exceptionally long and healthy lives.
▪Tea is rich in antioxidants
One of the main reasons why tea is good for your health is that it contains a high amount of antioxidants, especially polyphenols. Antioxidants are substances that protect your cells from damage caused by free radicals, which are unstable molecules that can cause inflammation, aging, and chronic diseases. Polyphenols, in particular, have been shown to have anti-inflammatory, anti-cancer, anti-diabetic, and anti-obesity effects.
Green tea, which is the most popular type of tea in East Asia, is especially rich in a type of polyphenol called catechins, which have been linked to lower risks of cardiovascular disease, stroke, and several cancers2. One of the most potent catechins in green tea is epigallocatechin gallate (EGCG), which has been shown to modulate various cellular pathways and inhibit the growth of tumor cells.
Black tea, which is more common in the West, also contains polyphenols, but they are mostly theaflavins and thearubigins, which are formed during the fermentation process of tea leaves. These polyphenols have also been associated with lower risks of heart disease and stroke, as well as improved blood pressure, cholesterol, and blood sugar levels.
▪Tea is linked to longevity in the Blue Zones
Another way to look at the benefits of tea is to observe the habits of people who live in the Blue Zones, regions of the world where people live longer than average. Three of the five Blue Zones are predominantly tea-drinking cultures: Okinawa, Japan; Ikaria, Greece; and Sardinia, Italy.
In Okinawa, people drink green tea regularly, which may contribute to their low rates of heart disease and cancer. Green tea is also part of their traditional diet, which is rich in vegetables, tofu, seaweed, and sweet potatoes.
In Ikaria, people drink herbal teas made from locally foraged plants, such as rosemary, sage, mint, and chamomile. These herbs have various medicinal properties, such as anti-inflammatory, antibacterial, antiviral, and antifungal effects. They may also help lower blood pressure, improve digestion, and enhance mood.
In Sardinia, people drink milk thistle tea, which is known for its liver-protective and detoxifying effects. Milk thistle contains a compound called silymarin, which has been shown to prevent liver damage from toxins, alcohol, and viruses. It may also help lower cholesterol, blood sugar, and inflammation.
▪Tea is part of a healthy lifestyle
Of course, drinking tea alone is not enough to guarantee a long and healthy life. Tea is best enjoyed as part of a balanced and nutritious diet, along with regular physical activity, social connection, stress management, and other healthy habits. Tea can also be a source of pleasure and relaxation, which can improve your mental and emotional well-being.
So, the next time you brew a cup of tea, remember that you are not only satisfying your taste buds, but also nourishing your body and soul. Cheers to a longer and happier life! 🍵
