Green tea has been imbibed by humans for many years, and its use has been recorded in China as early as give thousand years ago. This valuable beverage is made from the dry leaves of a tea shrub named Camellia sinensis, and it has been utilized for a diversity of health intents, such as enhancing mental alertness, ministering to stomach disorders as well as weight loss. Moreover, it contains extremely great antioxidant concentrations.
What are the health benefits of drinking green tea?
Green Tea and Catechins, or Antioxidants
This tea has considerable quantities of antioxidants which are called catechins, which work against free radicals, compounds which injures DNA and may lead to cancer, cell death, atherosclerosis as well as the forming of blood clots. Also, they impact the process of aging, as they can be said to be anti-aging substances. Thus, green tea has the ability to keep up high antioxidant concentrations, due to the fact that it is processed only minimally, as opposed to other sorts of teas that are fermented.
Green Tea and Cancer
Green as well as black tea has a positive effect on the prevention of cancer, though it is dubious whether it is green tea which is in fact accountable for this. It is believed that it is the polyphenols in green tea which help get rid of cancer cells and hinder their spreading. Researchers have found out that EGCg (or epigallocatechin gallate), a composite which can be found in the tea, inhibits the developing of cancer cells, and this compound can also kill cancer cells but not cause any harm to other tissues. Thus, consuming 4-5 cups of this tea can slow down the growth of cancer, and studies have shown a lesser incidence of this disease if this amount is imbibed.
Green Tea and High Cholesterol
This tea can at the same time decrease the total cholesterol count while raising the good cholesterol. Again, it seems it is polyphenols which this beverage contains which aid the body to flush out surplus cholesterol and impede its being absorbed by the intestines.
Green Tea and Kidney and Liver Issues
This tea is linked with a lower rate of kidney ailments, and also may shield the liver from the harm undergone from an excessive consuming of alcohol. Also, catechin polyphenols in green tea may help assuage viral hepatitis, an inflammation of the liver.
Green Tea and Losing Weight
Some researchers claim that if approximately 5 five cups of green tea per day are imbibed, 70 to 80 extra calories can be burned off, as it seems that the polyphenols in tea help in the digestion of fat. It is also a natural laxative, so it helps regulate the digestive system. Green tea burns up calories and stimulates the metabolism.
Green Tea and Tooth Decay
There is evidence that this tea can even aid in the preventing of the decaying of teeth. Considering that its abilities to destroy bacteria can help stop food poisoning, this tea can also exterminate the bacteria which may cause dental plaque.
Are There Any Negative Side Effects?
This beverage is considered to be harmless for adults, although an excess amount of green tea (which is more than 5 cups a day) can result in harmful side effects because of its caffeine content. Thus, the only negative effect that has been reported to date from drinking this tea is insomnia, as it contains caffeine. However, it has been proven that green tea contains a lesser amount of caffeine than coffee – there are approximately 30 to 60 milligrams of caffeine in 6 – 8 ounces of tea, and yet there are over 100 milligrams in 8 ounces of coffee. Also, chronic use can result in dependence.
