In the US, scientists once again conducted a study on the beneficial properties of coffee and, as it turned out, this drink not only has an invigorating and tonic effect, but also improves the work of the heart (it was previously believed that coffee negatively affects the work of the heart and experts recommended limiting the use of this drink or completely abandon it).
At the University of California, a group of scientists conducted several studies, and found that coffee is not as harmful as it was always assumed.
The specialists invited about two thousand people to participate in the study. Most volunteers noted that they drink at least 6 cups of coffee a day. Scientists compared the results of the survey and evaluated the health status of the participants in the study, and found that this fragrant drink stimulates the cardiovascular system and has a diuretic effect. The scientists noted that coffee helps to cleanse the body, but in large quantities the drink can actually provoke heart or vessel diseases, and also causes dehydration, in some cases because of the individual characteristics of the body there may be problems with the intestine.
In addition, it was found that coffee consumption and the development of serious diseases are not related, but still, excessive enthusiasm for an invigorating drink can harm, according to scientists, a day can drink no more than 4 cups.
This favorite drink was discovered in the 17th century and quickly spread throughout the world. At first, the fragrant drink provoked mistrust, but in the XIX century, coffee was universally consumed as an invigorating drink, until in the middle of the 20th century the harmful properties of coffee were discovered.
But recently, scientists have again turned their attention to coffee, and not in one study it was proved that coffee has a lot of useful properties, if, of course, do not abuse it. Scientists also investigated the properties of tea and chocolate and did not find that these products could harm health.
The danger to health can represent not only coffee, but also a coffee machine, in which, according to recent research, scientists have detected harmful bacteria in it.
Spanish specialists studied the densities of 10 different coffee machines and found that the microorganisms that propagate in them are resistant to various external influences - it is known that coffee beans have an antibacterial effect, however, the bacteria felt great in this environment, and they did not have a high temperature either (during the preparation of the drink the coffee machine heats the water to 96 0 ).
Further studies showed that the thick of coffee machines is an excellent medium for the reproduction of bacilli and acinetobacter, the process of fermentation of coffee beans promotes the appearance of harmful microorganisms. Even in coffee machines, various types of enterococci have been identified that pose the greatest danger to human health, since serious diseases such as inflammation of the spinal cord, the brain, urinary tract infections, etc., can provoke.
