The botanical name of Green tea is Camellia sinensis and it belongs from family Theaceae (this family is of tea). Green tea has been used since ages for health and to boost the immune system. At first it was used in China only and Chinese used it to heal any disease from simple headaches to severe infections. Later on as its health benefits were became known to everyone it was exported to United States, Europe, and Australia too. Asian countries are also a big consumers of green tea. Long ago it was used in Persia and even today in Afghanistan, Iran, Iraq and in many other Asian countries a cup of green tea is a must after meal. It is said that green tea digest food very well. Some of the benefits of green tea have been well researched but others have been created by marketers for commercial purpose.

Health Benefits of Green Tea

Green tea boost immune system. It fuels your immune system to fight against many diseases. The antioxidants present in green tea (poly-phenols) are very powerful in targeting free radicals and thus charging body to fight against diseases. It protects DNA from damaging.

Antibacterial: It is antibacterial in nature. Its antibacterial properties were known to the Chinese and Japanese before they knew about other benefits of it. They used it to treat colds, coughs and fever.

Antiviral: It is also said that it is antiviral too. In many viral diseases it is very effective.

Antioxidants: It contains many antioxidants like other super foods. The main antioxidant is epigallocatechin gallate (EGCG). This is a very powerful health boosting antioxidant. In many of the studies it has been proved that this antioxidant has the property of controlling the growth of cancer cells in body. It has also been proved that consuming green tea has healthy effects on cancer patients since it also kills the cancer cells but once cancer is in advance stages then green tea cannot stop the growth of more cells. As more ans more researches are being done on people who consume green tea it has been evidenced that those who consume green tea in their routine are less liable to develop cancer.

Lowering Cholesterol: It has also been beneficial in lowering blood cholesterol LDL. People who consume a diet rich in fats can reduce their chances of heart diseases by adding green tea in their diet. Japanese are least effected by heart diseases, the reason being that they consume green tea. Researches have proved that Epigallocatechin gallate is the most powerful of all antioxidants and its effects on lowering cholesterol are well documented.

Digestion: It helps digest food. In many countries green tea is consumed after every meal to digest food and it gives positive results.

Caffeine: it contains the least amount of caffeine as compared to other teas. six ounces of coffee contains more than 100 mg of caffeine while six ounces of black tea contains 60-70 mg of caffeine. On the other hand similar amount of green tea contains only 30 mg of caffeine. This shows that green tea is least harmful among all form of tea consumed today.

Tooth Decay: Green Tea is also rich in fluoride and may help to reduce tooth decay. Its benefits for teeth are enhanced if it is taken without sugar. As adding sugar can increase chances of tooth decay.

Weight Loss: As people knew about its benefits in reducing weight many companies have produced new products that contain green tea extracts. Green tea is widely been associated with weight loss and many people who even don't like the taste prefer to drink it just to loose some extra pounds.

Daily intake of Green Tea: There is no standard dose of green tea that has been recognized as safe. It depends on the diet pattern those who drink coffee or black tea along with green tea should consume less green tea than those who don't. For commercial sake many companies advertise that drinking 8-10 cups of green tea will help your body fight against cancer. Such claims speak more for publicity and less for reality. In general it is suggested by nutritionists that drinking 2-4 cups of green tea is enough to get all potent antioxidants in your body.

How to Brew Green Tea: Brewing green tea is a delicate process, since, green tea contains nutrients that can be lost by cooking for long time. The standard procedure is to boil water, and as the water starts rolling in the pan, turn off the stove and pour green tea leaves in it. Cover it for 2-3 minutes and it is ready to serve. Don't leave it in the cup for long time as the polyphenols will be lost in this way. Avoid use of sugar in green tea as sugar can reduce its effectiveness and it can also cause tooth decay, diabetes and many other diseases.

      Green tea is one of the super food and we all know that nutritionists are greatly focusing on the advantages of super foods so I think we all should take green tea in our routine diet.
