While energy drinks are thought to be a quicker route to a caffeine high, a new study has found that they can be considered dangerous in high doses.
The study, led by João Breda with the World Health Organization, explores why the world should be worried about energy drinks and what adverse health effects they can reap on society.
The study is largely concerned with younger adult populations, such as those in their teens and college-aged adults. A whopping 68 percent of teenagers consume energy drinks in Europe alone, based on a 2011 study from the European Food and Safety Authority.
They’ve also become quite popular among young children, through marketing tactics and fun advertisements, leading to a caffeine exposure rate of 43 percent in children.
Caffeine intoxication is the most dangerous adverse effect that can stem from energy drink consumption.
Healthy adults should have no more than 400 milligrams per day of caffeine. Pregnant women should not exceed 200 milligrams. Children should have no more than 45-85 milligrams per day depending on how much they weigh, according to an article on WebMD.
When you drink an 8-ounce cup of coffee you're getting somewhere around 100 milligrams of caffeine, according to WebMD. There is some variation from brand to brand. For instance, there are 165 milligrams of caffeine in 8 ounces of Starbucks coffee.
There is a range of caffeine content amongst the various energy drinks.
The caffeine content in 5-Hour Energy Decaf has 6 milligrams of caffeine in a 1.9 ounce serving. That would mean roughly 24 milligrams of caffeine in eight ounces.
Some energy drinks are comparable to that cup of coffee in their caffeine content, but many score higher with 5-Hour Energy Extra Strength soaring up to 242 milligrams of caffeine in a 1.9 ounce serving.
