The Organization of consumers and users (OCU) has warned that some cans of energy drinks contain very high amounts of caffeine. Exceeding 150 milligrams (mg), the maximum recommended amount per intake for an adolescent weighing 50 kilograms. In these cases, it is best to replace these with the same amount of coffee. That will give us energy in a more natural way, avoiding additives that are harmful to our health.
Energy drinks have more than twice the caffeine of a cola, but less than a cup of coffee. And in fact, compared to the 90 milligrams of caffeine in an average 330 milliliter can of an energy drink, a cup of homemade espresso has about 105 mg. While a cafeteria can have up to 180 mg.
Massive intake of caffeine in these amounts can cause cardiovascular problems
“Teens and tweens are enthusiastic consumers of energy drinks. It is not uncommon for them to take one or more cans to focus on a test, not fall asleep, to perform better in the gym and on weekends or to mix them with alcohol.
What they are most likely unaware of is that their cumulative consumption may translate into an intake of more than 285 mg of caffeine. Which is the maximum daily dose recommended by the European Food Safety Authority (EFSA) for a person weighing 50 kg. Habitual in many of these young people ”, has detailed the organization.
In this sense, the OCU has recalled that consumed in moderate doses, caffeine increases alertness and reduces drowsiness. But in excess it presents risks. Specifically, in the short term, it can interrupt sleep, cause anxiety and produce changes in behavior. While in the long term, it can cause cardiovascular problems. In fact, in people with high blood pressure it is advisable to moderate the consumption of both energy drinks and coffee.
But, apart from caffeine, many of these drinks contain other active substances such as taurine, L-carnitine or glucoronolactone. Whose concentration, unfortunately, is not reflected on the label. “The combined consumption of energy drinks with alcohol has an added risk: it can lead to a higher alcohol intake, because it reduces the feeling of sleep and allows to extend the night. What usually translates into a fully awake drunken state ”, has settled.
Genetics and blood pressure affect daily coffee consumption
If you’ve ever wondered why some people consume more coffee than others, it may be that the answer lies in genetics and blood pressure. And is that a study from the University of South Australia has shown that these two factors are an important part when measuring the coffee intake of each person. In this case, you should focus on both blood pressure and heart rate.
According to the researchers, this finding is very positive for being able to treat people according to these variables that will affect their daily lives. In addition, each person will be able to know how much coffee their body needs for its beneficial properties to act properly.
“People drink coffee for all kinds of reasons: as a stimulus when they feel tired, because it tastes good, or simply because it is part of their daily routine. But what we don’t recognize is that people subconsciously self-regulate safe caffeine levels based on how high their blood pressure is. And this is probably the result of a protective genetic mechanism, ”says Hyppönen.
