Green tea at birth is considered a medicine. After that was a drink only for the elite and royalty. Gradually, green tea is a refreshing drink of all classes. And now, green tea is considered one of the healthiest foods. Classified as 'superfood' or superfood. From bottles of drinking water to toothpaste tubes all have green tea in its composition.

1. What is green tea?

Green tea is a type of tea made to have the same taste as the freshest tea leaves. So after picking, fresh tea leaves are 'killed' immediately. 'Killing yeast' is a process in which fresh tea leaves are sautéed in a pan or steamed at high temperatures for short periods. At this time the 'yeast' or enzyme components in tea leaves are destroyed by high temperatures.
Yeast is the catalyst between oxygen in the air and the chemical components of tea leaves. When the yeast is gone, the oxygen cannot act on the tea leaves anymore. As a result, green tea is not fermented (or oxidized) anymore. And the final green tea not only retains the same taste as fresh tea leaves. But it also retains the health benefits of fresh tea leaves.
The health benefits of green tea are noticeable by modern science. Therefore, there is a lot of research on the ability of prevention and treatment of this tea. The health benefits of green tea come from groups of highly antioxidant compounds. The most prominent is EGCG, which is the most powerful antioxidant in green tea. EGCG, together with other substances, helps to reduce the risk of many diseases. Including some cancers.
Green tea is often confused with fresh tea leaves. Many people often mistake green tea for fresh tea leaves or for sale at markets or supermarkets. But in fact, green tea is the name of the non-fermented dry tea. And fresh tea leaves should be simply called as fresh tea leaves.
Another common mistake is that green tea is often used to specifically call matcha or Japanese green tea powder. But the truth is green tea powder or matcha is just one of many types of green tea.
Green tea has many types. In Vietnam, there is  Thai Nguyen green tea. In China, there is Longjing or Mao Feng. In Japan, there is Gyokuro or matcha.

2. Health benefits of green tea

A Thai study found that green tea may help with weight loss in obese people. Study participants had the same diet for 12 weeks. As a result, the group of people given green tea lost weight significantly. Compared to the group of unused ones. Scientists have found that drinking green tea promotes energy burning. Thereby helping to lose weight in obese people.
However, the studies usually last for several months. So losing a few kilos in a week like teas for weight loss is unthinkable. Although many of these weight loss teas contain mainly green tea. Instead of spending money on expensive weight loss tea made from easy-to-find ingredients. Then you should drink green tea daily. While supporting weight loss, there are many other health benefits.
