The University of South Australia researchers, Dr Ang Zhou and Professor Elina Hypponen from the Australian Centre for Precision Health investigated the connection between long-term coffee consumption and cardiovascular disease.

They were able to confirm that too much caffeine can lead to high blood pressure, a precursor to heart disease.

The study authors concluded that Drinking six or more coffees per day can be harmful to health and the risk for heart disease by up to 22 percent increase.

According to a statement the University was established by the scientists for the first time an upper limit for safe coffee consumption and cardiovascular health.

The most frequently consumed stimulant in the world

“Coffee is the most consumed stimulant in the world – he wakes us up, boosts our energy and helps us to focus. But people always ask: “How much caffeine is too much?””, Prof. Hypponen.

“Most people would agree that you may feel nervous, irritated, or even evil, if you drink a lot of coffee. This is because caffeine helps your body to work faster and harder,“ explains the study author.

“We also know that the risk for cardiovascular disease increases with high blood pressure, a well-known consequence of excessive caffeine consumption,” says Hypponen.

“A healthy heart and a healthy, maintain blood pressure, you need to limit the people their coffee on less than six cups per day – based on our data, six was the turning point, at the caffeine the circulatory began to affect risk negatively.“

It’s a matter of moderation

To reach their conclusions, used the research data to the UK Biobank of 347.077 participants in age from 37 to 73 years.

They found also in the case of persons that have the for faster caffeine-in charge of processing metabolizing Gene, CYP1A2, to the sixth Cup of negative effects.

“An estimated three billion cups of coffee every day around the world to drink,” says Prof. Hypponen.

“It is essential to know the limits of what is good for you and what is not,” says the scientist.”As with many things everything moderation turns; in the case of gluttony, the health will pay for it.“

Coffee increases blood pressure?

Studies show that regular Drinking of coffee affected blood pressure. A coffee filter also does not affect the level of cholesterol: in Order to increase this slightly, you would need to coffee beans or coffee powder, to chew, and in larger quantities. In 2003, the National heart, lung, and blood Institute of the United States drew a warning, to the people with high blood pressure only a little coffee should drink. A study of at least 150,000 women found no connection between coffee consumption and high blood pressure.

Coffee has a dehydrating effect?

A common myth is the assumption that coffee has a diuretic is. This thought originated, „since some of the older study data is read incorrectly wurden“, Helga Strube of the German nutrition society (DGE) stresses. By the amount of water influence led to a regular and uniform coffee consumption of course, fluid balance, and he could be counted in the “fluid balance safely”; quoted Strube of the “dpa”. The caffeine promotes the excretion of urine and sodium output by the kidneys, but moderate consumption of four cups a day, this was compensated for by the body. A prerequisite is, however, that overall, people are drinking enough, where as a rule of thumb, a minimum of 1.5 litres should be taken into account.

A glass of water to the coffee, while not necessarily required, form but a good Tradition. Coffee should be consumed – despite the fact that the fluid balance, and other positive health effects, according to the assessment of the DGE – expert as a source of enjoyment and not as a thirst quencher.
