Benefits of green tea

There are many kinds of tea. Teas can be roughly divided primarily on the genuine tea, fruit tea and herbal teas. Teas that come from the tea bush (Camellia sinensis) are so called “genuine teas”. Tea tree is an evergreen plant that grows mainly in tropical and subtropical climates.

Types of genuine tea are distinguished according to the length of the fermentation process of tea leaves and depending on the treatment process. Therefore we distinguish four main types of tea:

• Black Tea: This tea is the most common in Western countries. The leaves of black tea were significantly oxidized.
• Green Tea: The process of oxidation (fermentation) is interrupted by heat.
• Oolong tea: the oxidation process takes longer than the required time, but less than black tea.
• White Tea: Tea composed of young, Un-oxidised leaves (buds). In the West is white tea less known.

One of major component of tea is catechins, type of antioxidants in fresh leaves as much as 30% by weight. The highest percentage of catechins is in green and white tea, black tea due to the longer drying (oxidation) contains less catechins.

An important ingredient in tea is caffeine, a cup of tea contains about 30-90 mg, depending on the type of tea, producer, and mixtures. In the tea are also theobromine and theophylline, which have a similar effect as caffeine invigorating. Theobromine acts primarily stimulant, is effective longer than caffeine and improves mood. Other components of tea are fluoride to prevent tooth decay and vitamins.
