Green tea has many health benefits, some have been proven and some may just be folklore. Some of the various chemical compounds in green tea are: polyphenols and flavonoids; alkaloids, such as caffeine and the bromine; carbohydrates; tannins; minerals, such as F and Al. Epigallocatechin gallate is a very powerful antioxidant and is believed to be an important player in the therapeutic qualities of green tea. Tea that has been decaffeinated with a solvent such as Ethyl Acetate is going to have a much lower level of EGCG, than a tea that has been processed with a H2O)/CO2) method. Water decaffeinated tea will retain almost 95% of its EGCG. Along with the natural fluoride found in tea, polyphenols and catechins are associated with killing bacteria that cause tooth decay, bad breath, and gum disease-the number one cause for tooth loss. Adding sugar, honey, or other sweeteners to tea however, may negate these benefits. Numerous researches have demonstrated that tea is beneficial in preventing cancer including prostate, pancreatic, breast, colorectal, esophageal, bladder, lung, and stomach. The catechins found in tea prevent cell mutation, deactivate certain carcinogens, and reduce the formation and growth of tumors. It’s thought that tea helps diminish bone loss through antioxidant and anti-inflammatory activity. Additionally, tea’s health-promoting properties are thought to suppress the breakdown of bone while increasing the amount and activity of bone building cells. Evidence is still inconclusive in this area, but it’s thought that the catechins found green tea, create thermogenesis-the production of heat within the body which is related to burning calories. These compounds may inhibit certain chemicals in the brain, therby prolonging thermogenesis. A major concern with drinking so much tea is the caffeine. Though there is less caffeine in tea than in coffee, it does start to add up when drinking large volumes. But can one switch to decaf? The answer is, maybe. It all depends on how your chosen tea is decaffeinated. For people who are at-risk for developing cancer, it might be a worthwhile avenue to pursue. The manuscript delineates the revision of the most recent studies on green tea’s therapeutic potentialities and vigor and vitality of wellbeing.
