These days there is a fair amount of empirical support for the contention that drinking green tea is a healthy habit, but it is only during the past several decades that any formal studies have been carried out on the subject.Scientific interest in the drink was triggered in the 1970s when Japanese researchers made the observation that the people in Shizuoka, Japan had a much lower incidence of stomach cancer than people in other parts of the country. Subsequent in-depth studies showed that the difference was not limited to stomach cancer; that the population of Shizuoka actually had much lower rates of all types of cancer. It did not take long for attention to focus on green tea as it was commonly known that more of the brew is consumed in Shizuoka than in any other part of Japan, or probably, of the world.Green tea and black tea are actually made from the same leaves but by different processes. Most tea-producing countries ferment their leaves to make either oolong or black tea. The Japanese do not ferment the tea leaves, but instead steam them right after they have been picked. The activity of the fermenting enzyme is thereby stopped, and the tea leaves retain their green color. This is also thought to perserve the beneficial chemical compounds contained in the leaf.

綠茶和紅茶實際上是來自同一個葉，但通過不同的工藝製成。大多數茶葉生產國發酵的葉子，使無論是烏龍茶或紅茶。日本人不發酵的茶葉，而是蒸他們，他們都被接走之後。發酵酶的活性從而停止，茶葉保持其綠色。這也被認為是持之以恆包含在葉有益的化合物。

如今，關於喝綠茶是一種健康習慣的觀點，有相當一部分經驗支援，但只是在過去幾十年裡，才對這一問題進行了正式研究。

20世紀70年代，日本研究人員觀察到日本靜岡人患胃癌的發病率比日本其他地區的人要低得多。隨後的深入研究表明，這種差異並不限於胃癌;靜岡人實際上患各種癌症的比率要低得多。沒過多久，人們就把注意力集中在綠茶上，因為眾所周知，靜岡的啤酒消費量比日本任何其他地區，或者可能是世界上的啤酒要多。

綠茶和紅茶實際上是由相同的葉子，但通過不同的過程。大多數茶葉生產國發酵他們的葉子，使烏龍或紅茶。日本人不會發酵茶葉，而是在茶葉採摘後直接蒸。發酵酶的活性因此停止，茶葉保持其綠色。這也被認為可以抑制葉子中所含的有益化合物。

上世紀70年代，日本研究人員發現，日本靜岡人的胃癌發病率遠低於其他地區的人，由此引發了人們對這種飲料的科學興趣。隨後的深入研究表明，這種差异並不局限於胃癌；靜岡人的各種癌症發病率實際上要低得多。人們很快就開始關注綠茶，因為眾所周知，靜岡的綠茶消費量超過了日本其他地區，甚至可能是世界其他地區。
綠茶和紅茶實際上是由同一片葉子製成的，但工藝不同。大多數茶葉生產國發酵茶葉來生產烏龍茶或紅茶。日本人不發酵茶葉，而是在茶葉採摘後立即蒸煮。發酵酶的活性囙此停止，茶葉保持其綠色。這也被認為保留了葉子中的有益化合物。
