The caffeine present in the green tea gives the tea its stimulating effect, characteristic bitterness and taste. Green tea’s scientific name is Camellia sinensis. It is similar to the normal tea but its processing method is different.
The normal black tea is produced by fermenting the leaves of the tea. This fermentation changes the flavour and colour. The level of tannin and caffeine also rises due to fermentation. However, in case of green tea, the leaves are dried, and at times, steamed but they are not fermented.
This is what makes green tea look green when brewed. Different types of green tea are: Matcha, Houjicha, Bancha, Decaffeinated green tea, Genmaicha, Sencha, Gyokurocha and many others.
Health Benefits of Green Tea
• Stimulating effect:
Like any other tea, green tea also has great stimulating effect. This is due to the caffeine and the tannins present in the green tea ,  Although they have negative effects on the health in the long run, but they also act as great stimulants. This is the reason why a cup of green tea energizes and freshens up a person. It is ideal for fighting fatigue, sleepiness, laziness and improves blood circulation in the body.
• Helps to lose weight:
Green tea helps to lose extra weight. It enhances the rate of metabolism and leads to a faster consumption of the stored fat content of the body.
• Reduces cholesterol:
Because it is alkaline in nature, green tea also successfully reduces cholesterol.
Caffeine Content in Green Tea
Caffeine content in green tea varies from one type the other. A cup of green tea may contain caffeine of about 15 mgs to 75 mgs or even more in some cases. This is applicable for tea types such as Matcha green tea. There are different factors, which influence the level of caffeine content in green tea. One can use the following techniques to reduce the caffeine content of the green tea:
• Drinking green tea blends
• Avoiding powdered green tea
• Drinking “twig tea”
• Drinking green tea that are not at all shade-grown
• Whole-leaf green tea should be preferred rather than the green teabags
Certain things one should know about the green tea caffeine:
• Consumption of green tea instead of morning coffee will reduce caffeine by almost seventy percent. A cup of coffee may contain 100-150 mgs of caffeine, whereas a cup of green tea may contain 25mg of caffeine. Note that, longer brewing period can result in the tea being more strongly caffeinated.
• Moreover, if one sees that the caffeine in the coffee is showing negative toll on his or her health, he or she can switch over to green tea. This tea provides natural antibiotic effect, which kills the bacteria present in the mouth. This not only helps people who have bad breath but also helps to maintain a proper dental condition.
• If people want to consume green tea without caffeine, they can go for the decaffeinated green tea. It is a healthier choice where the caffeine is removed by using water and carbon dioxide through a process of “effervescence”.
Thus, whether one wants to consume green tea containing caffeine or one wants to consume caffeine-free, decaffeinated green tea is a matter of personal choice.Tags: caffeine, decaffeination, green tea, health, tea
