Energy Drinks and Health
The Appeal of Energy Drinks
Sipping a beverage that offers quick energy may appeal to people who feel fatigued or who believe caffeine can provide an edge when exercising or playing competitive sports. Although statements on the websites of energy drinks warn that these beverages may not be suitable for children, youth are among their largest consumers. An energy drink may be used by adolescents or college students cramming for exams through the night, or by a young athlete before an important game.
Negative Health Effects
While it is true that some controlled trials have shown temporary improved alertness and reversal of fatigue after taking energy drinks, as well as enhanced physical performance in young athletes, the majority of studies show an association with negative health effects. These include increased stress, aggressive behaviors like fighting, alcohol/cigarette abuse, increased blood pressure, increased risk of obesity and type 2 diabetes, poor sleep quality, and stomach irritation.
Ingredients in Energy Drinks
A typical energy drink may contain the following: carbonated water, around 40 grams of sugar (from sucrose and/or glucose), 160 mg or more of caffeine, artificial sweetener, and herbs/substances associated with mental alertness and performance but that lack scientific evidence with controlled trials (taurine, Panax ginseng root extract, L-carnitine, L-tartrate, guarana seed extract, B vitamins).
Special Concerns with Energy Drinks
- Amplified negative health effects in adolescents. Children and teens may experience heightened effects from the high amounts of caffeine, and added sugars including high fructose corn syrup, low-calorie sweeteners, and herbal stimulants, partly due to their smaller body size.
- Marketing tactics towards youth. Estimates show more than a 240% increase in U.S. and worldwide sales of energy drinks. It is a $21 billion industry, with marketing campaigns targeting youth and being sold in places that are easily accessed by this age group. Youth are exposed to energy drink advertising on children’s websites, computer games, television, supermarkets, and sporting events.
- Negative health outcomes. Emerging evidence has linked energy drink consumption with negative health consequences in youth like risk-seeking behaviors, poor mental health, adverse cardiovascular effects, and metabolic, renal, or dental problems.
- Excessive caffeine. Too much caffeine from any beverage, particularly when several are taken in one day in sensitive individuals, can lead to anxiety, insomnia, heart problems like irregular heartbeat and elevated blood pressure, and in rare cases seizures or cardiac arrest. Some energy drinks may contain as much as 500 mg per can (the amount in 14 cans of cola).
- High sugar content. Because of the excessive sugar content in some energy drinks, they carry the same health risks associated with other sugar-sweetened beverages.
- Dangers with alcohol. A greater danger is introduced if energy drinks are combined with alcohol, a trend largely seen in underage drinkers and associated with binge drinking. Studies suggest that drinking this type of cocktail leads to a greater alcohol intake than if just drinking alcohol alone.
- Lack of regulation. The Food and Drug Administration (FDA) does not regulate energy drinks but enforces a caffeine limit.
In conclusion, while energy drinks may provide a temporary boost in energy and alertness, they come with a host of negative health effects, especially in adolescents and young adults. The high levels of caffeine, sugar, and herbal stimulants can lead to an increased risk of obesity, type 2 diabetes, poor sleep quality, stomach irritation, and even heart problems. Furthermore, the marketing tactics used by energy drink companies often target youth, making them particularly vulnerable to the negative effects of these beverages. It is important for individuals, especially youth, to be aware of the potential risks associated with energy drinks and to consume them in moderation. Additionally, regulators should consider implementing stricter regulations on the production and marketing of energy drinks to protect public health.
