Particularly, a variety helps: tea to protect against cardiovascular diseases
Chinese scientists found evidence that tea may protect against cardiovascular diseases. The they identified in a large-scale study with 100,000 participants. A tea variant as well.
Regular consumption of tea reduces according to a study, the risk for cardiovascular disease. This was especially true for green tea, writing Chinese researchers, according to a long-term study with more than 100,000 participants in the "European Journal of Preventive Cardiology".
"The data situation is now so consistent that green and black tea have a vascular protective effect award kann", Hans Hauner, Director of the Institute for nutritional medicine at the Technical University of Munich who was not involved in the investigation says.
Previous studies on the health effects of tea consumption have shown mixed results. The Team of epidemiologists, Dongfeng Gu from Peking Union Medical College, interviewed more than 100,000 Chinese, who initially had no heart disease-circulation-to your tea consumption and other lifestyle habits. After that, people were observed in the Mediterranean for more than seven years. During this time, 3700 participants developed almost a cardiovascular disease, around 1500 died of a heart disease, and about 5500 other causes.
Researchers in the participants divided into two groups
In the analysis, the researchers divided the participants into two groups: those who drank per week at least three Times tea, and those beverages consumed rare or completely avoided. The regular tea drinkers had a. in comparison to the other group to a 20 percent lower risk of heart disease and a 22 percent reduced likelihood of stroke The tea consumption of ducks at the age of 50 to 70 years, had a good a year higher life expectancy than people from the comparison group.
In the case of over 14,000 subjects, tea consumption, at a distance of more than eight years, was checked a second Time. This result was according to the researchers, even more clearly: Who consumed all the while, regular tea, had diseases in the five following years, a 39 percent lower risk of heart or stroke than those who rarely drank tea or abstinent remained.
This ratio was, however, especially for green tea, while black tea was associated with a significant protective effect. "In our study population, 49% of regular tea drinkers consumed green tea mainly, whereas only 8 percent of the black tea preferred." This lower number also made it difficult to find an effect for black tea.
Green Tea: Full Of Polyphenols
Green tea contains many polyphenols, which may reduce blood pressure and the fat levels. The fermented black tea polyphenols would lose, however, these positive features might, surmise the authors. In addition, black tea will often drank with milk, which could affect positive health effects on the blood vessels.
It is also noticeable that the connection in men was more pronounced than in women: The problem could be, according to lead author Xinyan Wang the fact that significantly more male participants regularly drank tea as a female. In addition, strokes and heart were in women diseases are generally less common than in men. Both aggravating it, any protective effects.
In a commentary in the same journal three Italian commentators write the internist Vanessa Bianconi, University of Perugia, and the results were plausible, particularly with regard to green tea. Although previous studies have shown to tea consumption in the Western countries and inconsistent results. However, in view of the worldwide spread of tea, even a small individual can have positive effects on the population level significant effects.
Tea lowers blood pressure
The Munich-based diet doctors Hauner, who is a member of the scientific Advisory Board of the German heart Foundation, explains the found associated mainly with the effect of tea on vascular function, which could lower blood pressure slightly.
This is particularly the so called catechins are believed to be responsible, which occur mainly in green tea, and possibly also glucose and fat may influence the metabolism positively. "The good news is that even small Teemengen be sufficient to show a measurable effect."
