Many start the morning with a cup of aromatic coffee, but there are many contradictory statements around this drink. Coffee is said to be harmful to the heart, dehydrates the body or slows down the growth of children.

However, science has long dispelled these prejudices. In Popular Science Collected Substantiation of scientists.

Myth 1: Dark roasting makes coffee stronger

Many people think that the dark frying of coffee beans makes the drink more durable than light, because the content of caffeine is allegedly higher. And it is intuitively clear, because the dark frying makes the coffee stronger in taste.

However, it does not mean that such a drink has more caffeine. In fact, frying works on the contrary.

In 2017, scientists compared Caffeine content in coffee, brewed using the same mass of medium and dark grains. The experiment used exclusively Arabica grown in Kona region in Hawaii (USA).

The results showed that the concentration of caffeine in the samples of medium frying was higher than in dark grains.

If the more saturated taste of dark roasting coffee makes you feel more energetic, then it is not exactly because of additional caffeine.

Myth 2: Coffee slows down the growth of children

No study associates the consumption of coffee with the growth of children. Doctor of Medical Sciences Roy Kim explained For Cleveland Clinic, which is even unclear where this idea came from.

According to him, caffeine in coffee can really impair appetite, but « does not lead to a significant effect on the growth of the baby. »

At the same time, it is worth remembering that coffee can harm the health of children for other reasons.

« Although we do not have caffeine questions because of its impact on height, but this does not apply to children with sleep and attention »– the doctor said.

Roy Kim explained that children can disturb the heartbeat, cause anxiety, stomach disorders and mood changes.

Myth 3: Coffee leads to dehydration

As in other myths, the idea that coffee « removes water from the body » has some logic. Caffeine has a diuretic effect, that is, after its use, people more often have to go to the toilet.

Scientists Checked This thesis, having conducted an experiment, which was attended by 50 participants. They were offered two tests – in the first people drank four cups of coffee for 200 milliliters, and in the second replaced the drink with water.

In the end, scientists did not find a significant difference between the effect on the body of coffee and water.

« Our data does not show significant differences in the moisturizing properties of coffee and water over a wide range of hydration assessment indicators (providing the body with water – ed.) »– the authors of the work wrote.

Such conclusions make sense, since coffee is predominantly composed of fluid, which outweighs the effect of caffeine.

Myth 4: Coffee causes heart disease

Everyone who drinks coffee knows that a cup of drink can speed up the heart. This is the widespread myth that the drink has a detrimental effect on the health of this organ.

However, studies do not associate coffee with diseases of the cardiovascular system. Some indicate the opposite.

The study of the European Cardiological Society showedthat two or three cups of coffee a day can improve the health of the heart.

Scientists, having analyzed the data of 500,000 British, found that coffee consumption, in particular, barfein, is associated with a significant decrease in cardiovascular disease and mortality.

This does not mean that coffee is completely safe – caffeine in it can cause Physiological and psychological dependence, headaches, insomnia, anxiety and dizziness.

In addition, coffee should be refrain from people who have diseases of the stomach and liver. Therefore, it is worth remembering About the daily rate of caffeine and be attentive to your body. In the event of anxiety symptoms, you should consult your doctor as soon as possible.
