Green tea health benefits
According to the National Cancer Institute, the Polyphemus in tea have been shown to decrease tumor growth in laboratory and animal studies and may protect against damage caused by ultraviolet UVB radiation.In countries where green tea consumption is high, cancer rates tend to be lower, but it is impossible to know for sure whether it is the green tea that prevents cancer in these particular populations or other lifestyle factors.
The long-term intake of green tea was associated with improved blood pressure levels. Studies suggest drinking 3 to 4 cups of the tea to help regulate blood pressure. One study also stated that as a result of lowered blood pressure (due to green tea consumption), participants saw a reduction in coronary heart disease risk by 5 percent and stroke risk by 8 percent.Blood pressure is usually caused by angiotensin-converting enzyme (or ACE), an enzyme secreted by the kidneys. Most drugs for blood pressure act as ACE inhibitors. But green tea, unbelievably, is a natural ACE inhibitor. It prevents the action of this enzyme and helps lower blood pressure.
Sorry, but no drink or food melts the pounds off. While some evidence suggests that the active ingredient in green tea, EGCG, may help you drop a few pounds, other studies show no effect.But green tea is a smart swap for sugary drinks.

It also contains the amino acid L-thenian, which can work synergistic with caffeine to improve brain function.Many people report having more stable energy and being much more productive when they drink green tea, compared to coffee.
A 2006 study published in the Journal of the American Medical Association concluded that green tea consumption is associated with reduced mortality due to all causes, including cardiovascular disease.The study followed over 40,000 Japanese participants between the ages of 40 and 79 for 11 years, starting in 1994.The participants who drank at least 5 cups of green tea per day had a significantly lower risk of dying (especially from cardiovascular disease) than those who drank less than one cup of tea per day.
The catechizes in green tea play a major role in boosting your immune function. The tea protects against oxidants and radicals, thereby enhancing immunity .The EGCG in green tea has the ability to increase the number of regulatory T cells – and these help improve immune function and suppress autoimmune diseases.
Some controlled trials show that green tea can cause mild reductions in blood sugar levels. It may also lower the risk of developing type II diabetes in the long term.One study in Japanese individuals found that those who drank the most green tea had a 42% lower risk of developing type II diabetes.According to a review of 7 studies with a total of 286,701 individuals, green tea drinkers had an 18% lower risk of becoming diabetic.
