Tea was initiated by a Chinese emperor over 4,500 years ago before being popular. Tea has been one of the daily necessities in China since then. Chinese tea may be classified into three categories according to the different methods by which it is processed :
  • Black tea (fully fermented)
  • Oolong or Wulong tea (semi-fermented)
  • Green tea (unfermented)
It is important to know that black tea, even though it comes from the same plant as a green tea, will not give you the same benefits. Black tea during fermentation process loses most of its medical benefits.

Green Tea Process
Green tea produced by steaming fresh leaves at high temperatures therefore leaving a significant part of the nutritional and enzyme content intact. Only good and tender leaves are generally used for making green tea. Most flavored teas, such as jasmine, are made from the green tea.

How to Prepared?
Green tea is usually brewed using 1 to 2 teaspoons of the dried tea in a cup of boiling water. Green tea extracts are also available in capsule form. Many of my female friends have the habit to drink green tea to an extent like drinking water.

The best way to preserve all the disease-fighting nutritions is to drink your tea freshly brewed. All the decaffeinated, ready-to-drink bottled or instant teas will give you very little of natural health compounds. It is better to let your tea steep for about 4-5 minutes before drinking it.

How does Green Tea Help Weight Loss?
A study shows that green tea can help you reduce your weight by :
  • Increase up your metabolism. A research concluded that that over a 24-hour period, green tea extract increases the metabolic rate by 4%. Some said about 79 calories a day with a cup of green tea. If the claim is true, in a year, it will be 28,000 calories a year which is about 8 pounds (about 3.6 kilogram) of weight.
  • Green tea inhibits fat absorption and helps glucose regulation. Green tea help to inhibit the movement of glucose into fat cells. It helps to slow the rise in blood sugar after a meal. This prevents high insulin spikes and the subsequent fat storage.
  • Help reduce appetite. Study found that green tea caused rats to lose up to 21 percent of their body weight. Rats injected with a green tea extract lost their appetites and consumed up to 60 percent less food after seven days of daily injections.
Caution
Be cautious of the caffeine if you have health problems. For some people that have heart troubles, high blood pressure or stimulant sensitivities, the caffeine in green tea may not be good thing for you in long term. If you are worried about the caffeine from green tea, try taking green tea extract. Most green tea extract is made from decaffeinated green tea so you can still get the benefits without the caffeine.
