It's a drink which has become synonymous with a healthy lifestyle - but is China Green Tea the magical potion many health sites would have us believe? Green tea has been popular in China for centuries, and has been used in traditional Chinese medicine to treat a number of health issues - including depression. Its virtues have also been extolled by celebrities and so-called health experts for a number of reasons. These include its ability to help weight-loss, as well as containing antioxidants which are believed to help combat different types of cancer, heart disease and Alzheimer's. Given these claims, it's easy to see green tea as sort of magical elixir. 1. Green tea and weight loss Green tea contains B vitamins, folate (naturally occurring folic acid), manganese, potassium, magnesium, caffeine and other antioxidants, such as catechins. It's catechins - along with green tea's naturally occurring caffeine - which are thought to help the body burn more calories. Weight-loss products containing green tea have a higher concentration of catechins and caffeine than the typical green tea beverage. However, there's some bad news. A review from 2012 of 18 studies involving 1,945 people found no significant effect of weight loss from drinking green tea. 2. Green tea and cholesterol Thanks again to the catechins, in a reputable review from 2013 of 11 studies involving 821 people, it was found daily consumption of green and black tea (as a drink or a capsule) could help lower cholesterol and blood pressure. It's important to note, however, that the authors of the study pointed out the trials were short-term, and cautioned longer-term trials would be needed to substantiate their findings. These were back up by an earlier review in 2011, which found drinking green tea enriched with catechins led to a small reduction in cholesterol, a main cause of heart disease and stroke. Though no one could say for certain how much green tea a person would need to drink to reap the benefits. 3. Green tea and cancer On this the NHS is clear. There is no evidence drinking green tea protects against different types of cancer.

Although it is available in many different varieties, non-herbal teas fall into four basic categories: black, green, oolong and white. Many of the health benefits come from tea’s powerful antioxidants, called flavonoids. There are more than 6,000 types of flavonoids, and one of the most common categories are catechins. Much of the research on tea has focused on green tea because when compared to black tea, green tea contains 3.5 times more catechins. Green Tea Factory is made from mature tea leaves and is less processed than other teas. Since the leaves have not been fermented, but instead are dried and steamed, green tea can keep its high level of catechins. Epigallocatechin gallate (EGCG) is the most common catechin found in green tea and therefore has been the most researched. You can consume green tea as a hot or cold beverage. It is also available in a more concentrated form called an extract. A green tea extract means that the active ingredients found in the green tea, such as the catechins, have been removed from the dried green tea leaves to produce a more concentrated form. Extracts are available in liquid, powder, capsule, or tablet forms. Heat water to 160 – 170 degrees (Dont boil water as it will reduce the effectiveness of catechins in green tea) and pour in a cup. Now add green tea leaves to the cup (Add around 1 teaspoon of leaves to 1 cup water) and let them steep for around 2 to 3 minutes (For a stronger taste, steep the leaves for a longer time). Now strain the tea and it is ready to drink. You can add a few drops of lemon to it, to enhance the taste and increase the absorption of catechins.
