Tea in Our Life


Tea, a flurry of discoveries about tea's health benefits, plus renewed appreciation of its ancient heritage, has pushed tea to the fore. Tea has been treasured through the ages for its mellow taste, delicate aroma and amazing health benefits. Its antioxidants appear to lower cholesterol levels (LDL cholesterol), improve cardiovascular health (against heart disease) and help guard against some cancers, like lung, prostate and breast cancer. And some experts believe its flavonoids may inhibit the growth of plaque on teeth.
Beside that, to stay focused during hours of meditation, monks are known to have relied on the power of tea, especially green tea. Around the world, tea has become an integral part of many cultures, from English Breakfast and Darjeeling in the English speaking countries to Sencha and Matcha in East Asia. There are many varieties, with each region celebrating the joys of tea in its own unique way.
Now tea has become fashionable all over again, attracting health conscious consumers seeking a more natural and healthy lifestyle. And for good reason: Tea is loaded with powerful phenolic antioxidants that can, as part of a well-balanced diet, help promote wellness. Exciting research indicates that tea even has the potential to speed metabolism and promote weight loss.
How to measure the strength of an antioxidant is by its Oxygen Radical Absorbance Capacity or ORAC value. The ORAC value is a measure of the capacity of the product to subdue free radicals that damage cells. Foods which are believed to have high ORAC value are green tea and blueberries. But green tea has a very high ORAC value, outranking blueberries and more than two times as powerful as pomegranates.
Tea's active ingredients are caffeine in combination with the tannin that gives it its pungency and much of its aroma and flavor (which essential oils also enhance). The New York Academy of Medicine held a symposium on "Pharmacological and Physiological Effects of Tea" in 1955 and found that, for reasons they could not explain, tea, unlike coffee, does not cause insomnia, nervousness, or stomach irritation when drunk in quantity. The scientists' tests showed a cup of tea gives both an immediate and a delayed lift without secondary depressing effects later on. They agreed tea is a good agent for relieving fatigue and aids clearness of thought and digestion alike.
