However, while weight loss may result, this is largely due to fluid loss. The use of these teas remains controversial, and people are encouraged to use other methods of weight loss. Read now
Along with caffeine, which gives green tea its characteristic taste, bitterness, and stimulating effect, green tea is also rich in a group of chemicals, called catechin polyphenols (commonly known as tannins, which contribute to bitter taste and astringency). These catechin polyphenols include catechin, epicatechin, epicatechin gallate (ECG), epigallocatechin gallate (EGCG), and various proanthocyanidins. They are also known as flavonoids and are very powerful antioxidants. Flavonoids, together with some amino acids like thiamine, are responsible for the potent flavor of green tea.
Green tea has many health benefits. “It contains many nutrients, including antioxidants and anti-cancer and brain-healthy compounds,” Smith reminds us. One thing is for sure: regardless of whether or not you’ll shed pounds with green tea, drink it anyway. “All teas contain many healthful nutrients; it’s one of the healthier choices for a beverage!” Smith says.
Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects. In 2011, a panel of scientists published a report on the claims for health effects at the request of the European Commission: in general they found that the claims made for green tea were not supported by sufficient scientific evidence. Although green tea may enhance mental alertness due to its caffeine content, there is only weak, inconclusive evidence that regular consumption of green tea affects the risk of cancer or cardiovascular diseases, and there is no evidence that it benefits weight loss.
It’s become such a fashionable beverage that, last summer, the New York Post ran a story about how Victoria’s Secret models were flocking to Cha Cha Matcha, a hipster spot fluent in the preparation of various matcha-based miracle potions. A search for where to get “matcha” in New York, New York on Yelp yielded some 1400 plus results. Even mass market coffee purveyors like Starbucks have made matcha their mantra, with a vast range of offerings to cash in on the craze.
Tea culture of Korea was actively suppressed by the Japanese during the Japanese forced occupation period (1910‒1945), and the subsequent Korean War (1950‒1953) made it even harder for the Korean tea tradition to survive. The restoration of the Korean way of tea began in the 1970s, around Dasolsa. Commercial production of green tea in South Korea only began in the 1970s,. By 2012 the industry was producing 20% as much tea as Taiwan and 3.5% as much as Japan. Green tea is not as popular as coffee or other types of Korean teas in modern South Korea. The annual consumption per capita of green tea in South Korea in 2016 was 0.16 kg (0.35 lb), compared to 3.9 kg (8.6 lb) coffee. Recently however, as the coffee market reached saturation point, South Korean tea production doubled during 2010‒2014, as did tea imports during 2009-2015, despite very high tariff rate (513.6% for green tea, compared to 40% for black tea, 8% for processed/roasted coffee, and 2% for raw coffee beans).
