You have probably heard about the health benefits of drinking tea, especially green tea. Tea has been known around the world for thousands of years as the “longevity” beverage. Tea has been drunk in China since at least 3000 BCE. Tea is part of the Camellia Sinensis plant, and comes as black tea, which is fully oxidized, green tea, which is un-oxidized, and oolong, which is partially oxidized. We are going to focus on green tea in this article as that has shown the most health benefits.
Green Tea Rich in Polyphenols and Vitamins
Green tea is harvested as young, healthy, green leaves, and then is gently steamed. This helps to keep its green color and potent phytonutrients intact. All tea, however, is rich in tannin, flavinols, polyphenols, and several vitamins: vitamin C, vitamin P, vitamin K and vitamin B. True tea does contain caffeine, but in lower amounts than is found in coffee. Green tea also has less caffeine than black tea. It is well known to help banish fatigue, raise energy levels and boost mental powers.
Green Tea a Great Antioxidant
Researchers at the University of California at Berkeley have found that green tea is a great antioxidant scavenger, reducing free radicals in the body. japanese green tea health benefits Antioxidants seem to slow or prevent cell damage that occurs from exposure to excess oxygen by creating a barrier around cell tissue. Those who get lots of antioxidants in their diets seem to be able to slow down the aging process and avoid or at least put off the development of many chronic, degenerative diseases, like heart disease, cancer and diabetes.
Moderate caffeine intake seems to promote good blood circulation, so if you have strong adrenal glands, the caffeine in tea in moderation might actually be good for you. However, if you are like many Americans today, and have weak adrenal glands, you might want to try using a green tea extract with low amounts of caffeine instead, as caffeine is not good for those with weak adrenals. Even though it contains caffeine, tea seems to act as a nerve sedative, and can relieve headaches*. Tea also acts as a diuretic, and as such, can promote better kidney function*.
Green Tea Found to Help Prevent Arteriosclerosis and Cancer, Researchers Say
Researchers at the University of California have also found both oolong and green tea to help prevent arteriosclerosis, which leads to heart disease. Green tea has also been shown in many studies to prevent cancer, and to inhibit the development of pre-cancerous lesions as well.
Green Tea Boosts Immune Function
The Camellia Sinensis plant is known to be antibacterial and antiviral*. So you can use your tea to apply directly to cuts and burns as well, including sunburns. And when drunk or taken as an extract, it seems to help boost your immune function*, probably because of its antimicrobial action.
Polyphenols in Green Tea Support Blood Pressure, Blood Sugar* and More
Green tea is really a powerhouse of a beverage, and the polyphenols it contains have also been shown to support healthy blood pressure, blood sugar and cholesterol levels*. In addition, they have been shown to protect your DNA from damage that comes from chemicals and also radiation. This means that drinking green tea, and/or taking green tea extracts, can be very useful for all of us who are exposed to more and more chemicals in our modern-day world. If you live near a nuclear power plant, fly a lot (where you are exposed to high levels of cosmic rays), or are undergoing radiation therapy, you might want to consider adding green tea and perhaps also a potent green tea extract to your diet.
