Plan of our conversation: What is an energy drink? The action of "energy drinks". Stimulating effects. Negative action. Contraindications and consequences. Combination with alcohol. 7. There is always a choice. Life is a gift!

Slide 3

What is an energy drink? Energy drinks (“energy drinks”, “energy tonics”) are non-alcoholic drinks whose advertising campaign focuses on their ability to stimulate the human central nervous system or have an antisedative effect. It is true!

Slide 4

The effect of “energy tonics” One can of drink can contain approximately half to a whole daily dose of vitamins. Therefore, the medical restriction on the use of energy drinks is no more than one can per day. The caffeine content of energy drinks ranges from 240 to 360 mg/L, with a recommended upper tolerable intake of 150 mg per day.

Slide 5

Stimulating effects For example, it is known that glucose, like other carbohydrates, is quickly absorbed into the blood, is included in oxidative processes and delivers energy (carbohydrates) to the muscles, brain and other vital organs. Like any stimulants, they act according to a simple scheme - to take a lot of energy from the body at once, which leads to inevitable depletion of the nervous system and metabolic disorders. Manufacturers in advertising claim that drinks increase performance by stimulating the body's internal reserves... but how harmless is this?

Slide 6

Sometimes advertisements indicate that caffeine is present in its pure form and is not associated, as in coffee and tea, with other substances that soften its effect. This statement has no basis. Manufacturers sometimes claim that the stimulating effect of energy drinks lasts 3-4 hours (coffee only lasts 1-2 hours), but there are no links to relevant clinical trials.

Slide 7

Drinks containing high doses of biologically active substances can cause certain adverse effects: sleep disturbance; excitation; anxiety; tachycardia; increased blood pressure; arrhythmia; nausea and vomiting; short-term depression, etc. Energy drinks are most consumed by teenagers from 13 to 17 years old.

Slide 8

Combination with alcohol Energy drinks are sometimes mixed with alcohol. Energy drinks have a stimulating function, while alcohol has a depressant function. The harm of this combination lies in the ability of energy drinks to mask the influence of alcohol, as a result of which a person will not be able to take its influence into account, weakening control over the amount of drinking. Alcohol in large doses causes natural fatigue, but the stimulating effect of energy drinks can overcome it.

Slide 9

The widespread mixing of energy drinks with vodka and other alcohol led to the emergence of pre-mixed cocktails.

Slide 10

Danger! Regular consumption of energy drinks can cause addiction. Without them, after some time a person reaches: the phase of exhaustion; feels lethargic; weakness and is looking for a remedy to relieve this condition. A cup of coffee won't help here!

Slide 11

Just as there is a disease of the body, there is also a disease of the lifestyle. (Democritus)

What is included in energy drinks

The benefits or harms of energy drinks depend on what components are present in them. Almost all energy drinks have a standard composition.

Caffeine

All energy drinks contain it. A good activity stimulant. Drinking a mug of strong coffee or a mug of strong black tea will invigorate you within 10-15 minutes. Caffeine excites the central nervous system and causes tachycardia (rapid heartbeat). Therefore, constant use of this substance leads to increased excitability, irritability and depression.

Taurine

An amino acid produced in small quantities in the human body. Responsible for the normal functioning of attention, increases endurance. Used in the treatment of some serious health problems. One can of energy drink contains 400-1000 mg of taurine.

Guarana and ginseng

They have a similar effect to caffeine - the same invigorating effect. They also have side effects if used frequently. For example, insomnia and irritability begin.

Other components

• Thiamine, matein. It is essentially the same caffeine, differing in its source of origin. Theine is extracted from tea, and mateine ​​is a natural plant extract. It helps eliminate hunger and promotes weight loss.
• Guarin. Promotes increased blood sugar and negatively affects the nervous system.
• Theobromine. It is obtained from cocoa seeds, freeing them from fat. Taking the substance in reasonable quantities may work to prevent blood clots.
• Vitamins. They have a positive effect on the body.
• Carbonic acid. Promotes the effective absorption of all substances found in energy.
• Glucose. Contains the energy supply needed by a person. It restores muscle tissue and has a beneficial effect on the functioning of the heart and blood vessels. However, consumption in large quantities can cause side effects, which in turn cause irreparable harm to health.

Along with multivitamins, energy drinks have become one of the most popular nutritional supplements consumed by people of all ages. The vast majority of these people are teenagers.

Energy drinks are sold in bottles and cans of various types and capacities. Most often, they are sold in containers very similar to regular soft drinks, such as lemonades. They are also found in the form of so-called “energy shots”, which are sold in smaller containers with a higher concentration of active ingredients in the drink.

Caffeine is the most common ingredient used in almost all types of energy drinks. Its proportion is often from 70 to 240 mg for energy drinks in half-liter packaging, and from 113 to 200 mg in “energy shots”, up to 75 ml.

For comparison: A 0.33 ml can of cola contains about 35 mg of caffeine, and a 250 ml cup of coffee contains approximately 100 mg. Energy drinks may include other ingredients such as guarana (another source of caffeine, also called Brazilian cocoa), sugar, taurine, ginseng, B vitamins, glucuronolactone, yohimbe, carnitine, and bitter orange.

Such a great popularity of such drinks could not but affect the health care and food safety sectors. According to statistics in the USA:

• Between 2007 and 2011, the number of patients seeking help from health care providers due to the effects of energy drinks doubled. In 2011, one in ten of these cases resulted in the patient being hospitalized. That same year, 42 patients admitted to emergency departments were found to have consumed energy drinks in conjunction with alcohol, drugs, including prescription and over-the-counter medications.

And these figures are only growing.

• There have been cases, even fatal ones, in our country. Although these cases are isolated, they should not be discounted. So, one young man drank an energy drink, coffee from a restaurant and a soft drink, and later died from severe arrhythmia. According to doctors, this accident could have happened because the teenager drank all three drinks within 2 hours.
• Energy drinks are even more dangerous when consumed simultaneously with alcoholic beverages. 25% of students drink energy drinks with alcohol, and they drink them much more often than those who do not mix such drinks.
• According to the CDC, people ages 15 to 23 drink four times more energy drinks while drinking than those who don't drink alcohol together with energy drinks. In addition, people who drink energy drinks with alcohol are more likely to find themselves in unwanted or dangerous situations.

What does the science know about energy drinks?

More and more scientific and statistical evidence shows that energy drinks can cause significant harm to human health. This is especially true for children, adolescents and young adults.

Several studies have, in fact, shown that energy drinks can slightly improve physical endurance. There is limited evidence that they provide muscle strength. Energy drinks may help improve reaction time and alertness, but they may also cause hand tremors.

The amount of caffeine in energy drinks varies greatly from drink to drink, and it can be difficult to determine the actual amount. Such beverages may be marketed as beverages or as dietary supplements and the label information may not be accurate.

The dangers of energy drinks.

• Large amounts of caffeine can cause serious problems with the heart and blood vessels. Such problems include: irregular heart rhythm, increased heart rate, increased blood pressure. In children, caffeine can cause irreparable harm to the nervous and cardiovascular systems that have not yet developed.
• Drinking caffeine can also cause anxiety, sleep problems, digestive problems, and cause dehydration.
• Guarana, which is also often used in energy drinks, also contains caffeine, thereby further increasing the specific gravity of caffeine in the drink.
• A person who drinks caffeinated drinks with alcohol may feel less drunk when compared to the same amount of alcohol without energy drinks, but this is not the case. Their coordination of movements and reaction time are equally impaired.
• Excessive consumption of energy drinks by adolescents can disrupt their sleep patterns and cause them to increase risk-taking behavior and anxiety.
• One can of energy drink can contain from 54 to 62 grams. added sugar. This amount already exceeds the recommended daily intake of sugar. This can lead to many serious medical problems, including obesity and diabetes.
• In addition, drinking energy drinks every day can make a person's body think that it cannot function properly without them. The body gets used to receiving additional energy from carbohydrates (sugar), because it is produced most easily from them with the least effort on the part of the body. But excess energy depletes the body, in particular the nervous system.

conclusions

In the modern world, we are all in a hurry to get somewhere. Hard work, sports, you have to get up early, it’s difficult to study, and so on. It's no surprise that energy drinks are becoming increasingly popular. After all, they are so colorfully advertised, promising to save a person from these problems. And indeed, they strengthen some body systems. However, we should not forget that they can cause significant harm to health.

Is it worth risking your health for short-term benefits from energy drinks?

These questions should be asked by every person who drinks energy drinks. And of course, parents should think about this and, if possible, protect their children from using them.

Isn't it better to stick to a healthy lifestyle, get good sleep, eat right and exercise, because this will bring you much more benefits, and for the rest of your life.
