A big big HELLO to all the members!
As there have been many topics regarding Green tea and its benefits, so I thought why not have a discussion on it..?
Reduces high blood pressure. Drinking green tea represses angiotensin II which leads to high blood pressure.
Lowers blood sugar. Green tea polyphenols and polysaccharides are effective in lowering blood sugar.
Fights cancer.There have been many studies that have shown that green tea catechins are effective at preventing cancer.
Green tea also boosts the immune system because of its high concentrations of polyphenols and flavenoids. ______________________________________________________________

Cut Your Cancer Risk
Several polyphenols - the potent antioxidants green tea's famous for - seem to help keep cancer cells from gaining a foothold in the body, by discouraging their growth and then squelching the creation of new blood vessels that tumors need to thrive. Study after study has found that people who regularly drink green tea reduce their risk of breast, stomach, esophagus, colon, and/or prostate cancer.
Soothe Your Skin
Got a cut, scrape, or bite, and a little leftover green tea? Soak a cotton pad in it. The tea is a natural antiseptic that relieves itching and swelling. Try it on inflamed breakouts and blemishes, sunburns, even puffy eyelids. And that's not all. In the lab, green tea helps block sun-triggered skin cancer, whether you drink it or apply it directly to the skin - which is why you're seeing green tea in more and more sunscreens and moisturizers.
Steady Your Blood Pressure
Having healthy blood pressure - meaning below 120/80 - is one thing. Keeping it that way is quite another. But people who sip just half a cup a day are almost 50% less likely to wind up with hypertension than non-drinkers. Credit goes to the polyphenols again (especially one known as ECGC). They help keep blood vessels from contracting and raising blood pressure.
Protect Your Memory,
Green tea may also keep the brain from turning fuzzy. Getting-up-there adults who drink at least two cups a day are half as likely to develop cognitive problems as those who drink less. Why? It appears that the tea's big dose of antioxidants fights the free-radical damage to brain nerves seen in Alzheimer's and Parkinson's.
The younger and healthier your arteries are, the younger and healthier you are. So fight plaque build-up in your blood vessels, which ups the risk of heart disease and stroke, adds years to your biological age (or RealAge), and saps your energy too. How much green tea does this vital job take? About 10 ounces a day, which also deters your body from absorbing artery-clogging fat and cholesterol.
Oh yeah, one more thing. Turns out that green tea speeds up your body's calorie-burning process. In the every-little-bit-counts department, this is good news!...................................................
their are also some side effect of green tea.................................................
You may have heard of the many health benefits of green tea. But do you know green tea side effects exist?
The health benefits of green tea have been highly touted in China for centuries. In the west, we are just beginning to realize how much our health can be improved by daily consumption of this miraculous beverage. But even good things can have adverse affects for some people. Although most of us can safely drink three to six cups per day, there are a few green tea side effects you should be aware of.
There is about half as much caffeine in green tea as there is in coffee. Most people find that this substance, labeled a drug because of its stimulating effect, gives them a bit of a lift, and a temporary increase in energy. That's why we like to start the day with a cup of coffee or tea! Some people, however, are sensitive to caffeine, and should avoid it.
The Federal Drug Administration has determined that caffeine is a safe substance. The American Medical Association agrees that, in moderation, this drug is not dangerous. However some people may find that caffeine makes them jittery, nervous, or edgy. It can increase the symptoms of anxiety, although it has also been shown to be a mood enhancer. It can also cause sleeplessness, especially if ingested late in the day.
While caffeine leads to a temporary increase in blood pressure, there is no evidence that ingesting it can lead to heart disease or hypertension.
Unless you have a noticeable sensitivity to this substance, there is no reason to think that this will be a green tea side effect you have to worry about.
Research indicates that pregnant women may want to limit their intake of green tea. The same compound that makes this beverage a great cancer fighter may interfere with the way our bodies absorb folate, a B vitamin that is important to proper fetal development. EGCG, an antioxidant found in vast quantities in green tea, attacks cancer cells by bonding with an enzyme called methotrexate. This same bond inhibits the metabolism of folic acid.
Pregnant women should consult with their doctors about how much green tea is appropriate for them. Likely its consumption should be limited during the first trimester of pregnancy.
There is evidence to suggest that tea inhibits absorption of iron. For most people, this is not a problematic. For anyone with an iron deficiency, however, this means that you might need to limit your intake.

The major concern with drinking too much green tea is the caffeine it contains. Too much caffeine can cause nausea, insomnia or frequent urination.
New scientistpoints to recent research has shown consuming very large quantities of green tea can be dangerous as it can cause damage to the liver and kidneys:
Green tea is good for you, but only if drunk in moderation. While the polyphenols in green tea are credited with preventing heart disease and cancer, it seems they can cause liver and kidney damage if consumed in very large quantities, a review of studies into the toxicity of polyphenols has shown.
So drinking green tea has lots of benefits and these benefits may outweigh the risks.
