Coffee is one of the most popular drinks on the planet and many negative errors are connected to it. Popsci.com information portal divorce The most popular legends about coffee and caffeine.
Dark roast is not stronger
Many people think that darker and more saturated seeds with caffeine rather than bright fried particles. Theoretically, everything is reasonable – dark frying has a more pronounced flavor, which means that more caffeine is needed. But in reality, this is not so.
The difference in dark and light frying is only the way the seeds are fried. Scientific works in 2017, published in Nature, compared the caffeine level in coffee welded from Arabica of fried and dark fried. The numbers show that there are more caffeine in the average frying samples.
Coffee does not prevent growth
In the same way, many people are sure that in all cases, children do not drink coffee or any other caffeine beverages, because this ingredient is considered to be negatively affected by younger organisms. But this belief does not have any scientific foundation. Finding the origin of this hearing is a difficulty: the maximum level that caffeine may be accused of inhibiting appetite. However, this property is not converted into a tangible effect for children's development.
In this case, coffee can be harmful to children for other reasons. Children drinking coffee may have an impulse, abnormal anxiety, problem with intestines and sharp mood changes.
Coffee does not dry out the body
In the legend of the characteristics of dry coffee, again, there is a certain logic. Caffeine is a diuretics, which means a coffee drinker will most likely urinate and lose a lot of liquid. But in 2014, published in the Journal of Science Plos One, exposed this hearing. For one of the experiments, each of the 50 male volunteers drink four cups of coffee 200 million, then they drink water. Result? Statistics show that coffee has no significant pull effect.
Coffee does not cause heart disease
Finally, the last legend: Coffee is said to lead to cardiovascular diseases. And again, in this illusion, there is a part of the truth – every coffee lover knows that a cup of drink really accelerates the pulse. But scientific research is not associated with coffee and heart disease. In 2022, the European Heart Association published a work showed two or three cups of coffee a day, in fact, even could improve the health of the heart. At least this is proved by data collected from 500,000 residents of the United Kingdom.
