The extraordinary health benefits of green tea

Green tea is an Asian common beverage has picked its popularity throughout Latin from North. Many are opting for green tea as a healthy alternative to coffee and other hot beverages. Research has shown that green tea is rich in antioxidant polyphenols which have extraordinary health benefits.

green, black and oolong tea are all part of the same species called Camellia sinensis. local growing conditions variability and create a multitude of distinctive leaves. Processing the leaves plays the most important role in the creation of three types of teas paper. The length of time that are processed dictates the color, flavor and nutrient content of different varieties of tea.

Green tea is higher in antioxidants

Green tea is the least processed of the three and contains the highest ORAC (Oxygen Radical Absorption Capacity) of three teas. Green tea is rich in polyphenol antioxidant catechin called epigallocatechin-3-gallate (EGCG). This antioxidant is considered by many to be responsible for the health benefits associated with drinking green tea.

EGCG is considered to be a hundred times more powerful than vitamin C and twenty times more potent than vitamin E. The powerful ability to eliminate free radicals which causes the green tea one of the best anti-aging herbs. EGCG is one of only a handful of anti-oxidants that has demonstrated its ability to influence the formation of mutant DNA to reverse chronic diseases.

Green Tea lowers the risk of mortality

of 1 September 2006 study in the Journal of American Medical Association showed that drinking green tea reduces the risk of death from all causes, including cardiovascular disease. This was a study of the following eleven years 40,530 adults between the ages of 40-79 in the northeast region of Japan. Eighty percent of the population drinks green tea and more than half consume at least three cups a day.

Those who drank five or more cups a day had a significantly lower risk of death from all causes than those who drank less than one cup of green tea a day. The men had a 12% lower risk of mortality, 22% lower risk of dying from cardiovascular disease and a 42% lower risk of dying from a stroke. Women had a mortality rate 23% lower and 31% lower risk of dying from cardiovascular disease and a 62% lower risk of dying from a stroke.

Green tea and cancer

A meta-analysis of thirteen studies published in carcinogenesis July 2006 revealed that women who drink green tea have a 22% lower risk of developing breast cancer than women who do not drink green tea.

A study published in December 2004 Cancer Research discussed how EGCG in green tea was able to decrease similar to that factor insulin-1 (IGF-1) growth, while that increased levels of IGF binding protein-3, which binds IGF-1. This reduces the risk of breast, colon, prostate and lung cancer. Also inhibits cancer survival key proteins and reduces expression of compounds associated with cancer metastasis.

A study published in Cancer Research in March 2005 showed that EGCG inhibits the enzyme dihydrofolate reductase (DHFR), which cancer cells need to grow. In fact, DHFR is a common goal of many drugs against expensive and toxic, such as methotrexate cancer. EGCG does not bind so strongly and is not as powerful as methotrexate, but has no negative effects on normal cells found with the use of methotrexate.

green tea increases immunity and prevent the flu

A November 2005 issue of Antiviral Research showed that EGCG inhibits the flu virus to replicate in culture cell phone. Scientists found that blocking the hemagglutinin virus enzyme that inhibits its ability to infect other cells. It also suppresses the synthesis of viral RNA by alteration of the key properties of the viral cell membrane.

ECGC has been shown to suppress pathogenic viruses such as Epstein Barr virus, herpes simplex, HIV-1 and influenza virus. Green tea contains high levels of L-theanine has been shown to activate human lymphocytes gamma-delta T to proliferate and make gamma interferon Si-G. Si-G is a powerful antimicrobial cytokine that is the first line of defense in the blood stream infection.

Green tea also contains small amounts of alkyl amines that are present in pathogenic organisms. When we drink green tea, alkylamines this act as relatively weak antigens that do not fully activate the immune system, but they get it in a ready state. This prepares the immune system against bacterial and viral invaders.

green tea as a stimulant Th2 immune

Some natural health practitioners have marked green tea as a stimulant agent Th2. Although this has not yet been shown through research, there are several studies that indicate that green tea may have this effect. This herb would be particularly effective for people with a predominance Th1, as it will help balance the immune system.

is recommended for those with predominant Th2 conditions to make a snap intentionally challenge when they see how your body responds to green tea or other compound stimulating Th2 before they start using it indiscriminately. If proven through blood tests cytokine or through challenging herbal supplement or that the individual has a Th2 dominance, then it is best to avoid green tea.

Green Tea Caffeine Content and contraindications

Green tea contains caffeine, but less than half of that found in coffee. The amount of caffeine in the green tea varies depending on the amount of tea used, branded and quality. The first infusion of green tea leaves is the highest quality and has the most caffeine.

is extremely important for organic green tea as the conventional tea can be sprayed with highly toxic pesticides and herbicides. Many coffee shops and large companies ship green tea that is produced commercially and contains a large amount of environmental toxins. This is unhealthy and should be avoided.

Pregnant women and infants should not drink large amounts of green tea and its ability to bind to DHFR can increase the risk of deficiencies of folate in the newborn and increase the risk of spina bifida or other disorders the neural tube.
