Transcript for New Energy Drinks Target Video-Gamers
Welcome back to "Gma." Time now for the "Heat index" and today's "Hot button," energy drinks that target video gamers with promises of increased energy, greater focus. But could they put your teenagers at risk? The story we first saw in "The New York times" and Paula Faris has the latest. Reporter: You know them by name, rockstar, red bull and monster, some of the biggest brands in the energy drink industry. But there's also a drink growing in popularity called fuel that advertises to be all natural and it's trying to reach a new audience of gapers. Hi, I'm going to hit the late -- Reporter: Doug martin who is responsible sr.ed by fuel plays video games up to 12 hours a day. When I'm playing in a big tournament it makes me feel alert and confident. I never had a crash or a jitter. Reporter: But doctors say it has the same amount of caffeine as other energy drinks. This energy drink that's proclaiming to be natural and healthy has taken out of it the chemicals in sugars but it's incorporated in what they're calling herbals or natural substances. These actually interact with the caffeine and can be more dangerous. Reporter: We reached out to gamma labs for comment. The company saying the ingredients in fuel are blended at ratios to maximize focus and concentration. Among energy drinks we are one of the healthiest choices on the market and as with any comfortable natured product, moderation is visible." Some energy drink manufacturers have come under attack for marketing to children. Causing the top makers to stop targeting kids under 12 years old. But overall, sales still booming. One-third much video gamers are under the age of 18. They're into motocross, skateboarding, women in bikini, all of these are used in the marketing campaigns. That's not an accident. Reporter: For "Good morning America," Paula Faris, ABC news, New York. Okay, Dr. Jen Ashton here now and thee things are labeled all natural but all natural isn't always good. That doesn't always mean safe. Look at this as a visual analogy. I thought Dan might be hungry so I brought him some breakfast. These represent some of the ingredients that you can see in a lot of energy drinks, so if you look at yogurt as the caffeine, blueberries as something like sugar. Granola as something called guarana and raspberries as taurine, but when you mix them together as you do in a lot of energy drinks, grab that, Lara, then they have -- they can have different effects and the fact is, you just don't know how they're going to add up. There's new research that says that these drinks have the possibility of linking to other problems. Right, now, listen, you have to consider this to be clear in moderation, a little bit of energy drink certainly in an adult, no problem. When you're talking about teens and adolescents that's where you can get into trouble and the literature has found an association, not a cause and effect but association between these energy drinks and things like increased use of video game, decrease in sleep, caffeine toxicity and go on to see other high risk behavior, alcohol consumption and smoking and poor school performance. You mentioned video gaming. Do we know anything more about extended -- Research is ongoing. Almost every teenager including my son is doing it. A little bit can be fine. They've actually shown some positive effects with something like Nintendo wii with traumatic brain injuries. I'm told by my son there are many positive effects. My son too so we'll be following it. We don't know a lot. When you finish mixing that can you hand it down here. Yes. Taking questions all morning on Twitter. Exactly.
