Benefits of Green Tea

Japanese researchers have found that if the average person were to drink five cups of green tea a day, they would burn an extra 70 to 80 extra calories. This is due to the high amount of polyphenols that cause thermogenesis - the process of heat production in the body1 and fat oxidation. It increases the metabolic rate without increasing the heart rate. Although this is not even close to the 500 calorie deficit required to lose weight, it certainly does no harm to include green tea in any diet, considering the health benefits of the drink.

Green tea is made from leaves of a plant called camellia sinesis that has undergone minimal processing and oxidation. It is usually brewed with freshly boiled water and drunk throughout the day.

Green Tea Benefits

In fact there are many other health benefits associated with green tea due to the unusually high levels of flavonoids2 found in green tea, which have anti-carcinogenic and anti-oxidative effects, according to the US Department of Agriculture. This table compares the average amount of flavonoids found in food and drink:
