ОглавлениеMyths about green tea
The most important ingredient is caffeine (formerly theine, tein, theine). Depending on the type of green tea, the amount of caffeine varies.
Green tea is not drunk as frequently in Germany as black tea. Out of 100 tea drinkers - black and green - about 60 drink black tea and the rest drink green tea. For more information about the consumption of tea, see Myths about black tea.
Green tea differs from black tea in that the leaves (leaves of Camellia sinensis) are not blended. Another difference is in the preparation, taste, ingredients and effects. The main ingredient is caffeine (formerly known as teein or theine) which can vary greatly from one type of green tea to another. Most of the caffeine is found in the Japanese tea varieties Gyokuro and Sencha. The least caffeine is found in Kukicha and Bancha varieties. Other ingredients are epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate. The effective health substances are the catechins, which also cause the bitter taste. The taste of the tea depends on the concentration of amino acids. The higher the concentration, the better the taste. Shade the tea more often in spring and the proportion of amino acids increases.
Other ingredients are vitamin A, vitamin B, vitamin B2, calcium, potassium, magnesium, phosphoric acid, copper, zinc, nickel, carotenes and fluoride. Green tea also contains more tanning agents (tannins) than black tea.
For nervous stomach and intestines, green tea has a calming effect, but for the sluggish intestines it has a constipating effect.
Green tea is good for the cardiovascular system
Right! The Japanese have found this out in an eleven-year study with over 40 thousand adults aged between 40 and 79 years. Known as the Ohsaki Study. However, the condition is that at least five cups of tea must be drunk each day. The result: the death rate was 12 percent lower in men and 23 percent lower in women. For cardiovascular diseases, the death rate was 22 percent lower for men and 31 percent lower for women.
Green tea protects against cancer
NO! It has not been scientifically proven that the natural brew protects against cancer. But: In the peoples where green tea is drunk more often, the rate of cancer was significantly lower than in the rest of the world where this tea consumption was neglected. Scientists blame the polyphenols (especially epigallocatechin gallate) for this.

Green tea can protect against diabetic nephropathy
Right! This kidney disease is caused by diabetes mellitus and in extreme cases can lead to kidney failure. The polyphenols contained in the tea intercept free radicals in the body and thus protect the kidneys.
Green tea enhances the effect of antibiotics
Right! Scientists in Egypt have found out that taking antibiotics and drinking green tea increases the effect. This has been proven in 28 different infectious diseases. Even antibiotic-resistant bacteria became vulnerable again!
