Drinking tea reflects a lifestyle where experimenting with aromas and tastes of all kinds is appreciated. Only a few know that green and black teas are leaves of the same herb, Camellia sinensis, they are just processed differently.
The freshly gathered leaves are first left to dry, and then they are processed, i.e. crushed. The juice that is released from the cells, combines with the air oxygen and this process is called fermentation. During this process, essential oils are released, which is of great importance for the tea itself. This is how black tea is made.
What is the difference between green and black tea?
The difference between green tea and black tea is that the former one is unfermented tea. Shortly after they are picked, the leaves are processed with water steam. This prevents fermentation and the leaves preserve their green color. Green tea, thanks to the manner in which it is processed, preserves a great part of the active ingredients and, compared to black tea, has more powerful properties. Black tea is rich in caffeine and antioxidants and therefore is particularly recommended for morning wake-up calls for your body and for a day packed with activities. Of course, there are a lot of other herbal teas that can help your body as well.
Preparing of Tea
When tea is being prepared it is important to correctly combine the amount of tea, the water temperature and the duration of the infusing. The quantity of dry tea used to prepare one cup depends to a great extent on the personal tastes of the consumers. This beverage is prepared to be stronger or weaker through the quantity of tea used, not through the duration of infusing. The temperature of the water that is poured over the tea leaves is determined by their level of fermentation. The pre-boiled water is left to cool until it reaches a temperature suitable for a certain kind of tea. For semi-fermented or unfermented tea, the temperature is lower in order to preserve the antioxidants. The temperature of infusing is higher for the fermented kinds of tea in order to extract the compound polyphenol molecules.
The benefits of tea
Although doctors and nutritionists continuously accentuate that our body needs a great amount of fluids, research shows that as much as 80% of the population does not comply with that. A reminder: Fluid deficit can cause symptoms of dehydration and other inconveniences, from lethargy to headaches and fatigue. Tea drinking combines the pleasant and the beneficial because aside for hydrating, it also has a pleasant taste and beneficial effects on the body.
Green tea is rich in flavonoids, or to be more precise, polyphenols which have powerful antioxidant properties. Polyphenols neutralize free radicals which have a destructive effect on the cells (a reason for the developing of various illnesses) and speed-up the aging process. Active polyphenol in green tea leaves is an around 200 times stronger antioxidant than vitamin E. The same polyphenol is responsible for blocking the effect of several factors, such as cancerous factors, ultraviolet light or already existing metastases.
There are several published studies on polyphenols from young green leaf tea that affirm that they have a significant role in preventing various skin diseases caused by external factors.
