Tea in the spotlight of science: The positive properties of tea on health
Tea receives a lot of attention in naturopathy. In the meantime, the science of tea's positive effects on health is on the trail. The tea experts from "Tea Exclusive" present some scientific findings about the preventive and healing effects of the different types of tea.
Green tea for a longer life According to a Japanese long-term study with over 40,000 participants (Ohsaki National Health Insurance Cohort Study), the consumption of green tea has a positive effect on life expectancy. Among participants who drank at least five cups a day, the death rate due to cardiovascular diseases decreased by 12 percent in male participants, and by 23 percent in female participants. "Green tea has a high proportion of polyphenols, which are said to have a positive effect on health," explains Natalia Panne from www.tea-exclusive.de.
Rooibos tea - protection against heart attack? The consumption of six cups of South African rooibos tea is said to protect against arteriosclerosis and the associated complications such as heart attack or stroke, according to a scientific study by the Cape Peninsula Technical University. "The study showed that after six weeks the polyphenol content in the test subjects' blood was significantly higher and the blood lipid levels of the participants improved", explained Natalia Panne from tea-exclusive.de.
Tea protects against brain tumors Tea can protect against the formation of brain tumors, according to the EPIC study (European Prospective Investigation into Cancer and Nutrition). The nine-year study with over 500,000 participants from ten European countries came to the conclusion that the consumption of tea can reduce the risk of developing tumors in the central nervous system. "Tea contains many antioxidants, which are probably the reason for the protective effect," says Natalia Panne.
Lemon instead of milk in tea A study by the Berlin Charité showed that the English custom of enjoying tea with milk cancels out the presumed health effects of the drink. Researchers at Purdue University in America advise a shot of lemon juice in tea. “The additional vitamin C from the lemon protects the polyphenols contained in the tea from breakdown during digestion. This allows the body to absorb more of these ingredients, ”said Natalia Panne.
Tea for the Cold Indian researchers at the Post Graduate Institute of Medical Education and Research in Chandigarh suspect that zinc can relieve the duration and severity of colds. The scientists also found evidence that zinc can prevent unpleasant infections. “Tea has always been a home remedy for colds and colds. Many types of tea also have a high zinc content, especially in rooibos and green tea, ”says tea expert Natalia Panne from" tea-exclusive ". (pm)
