Caffeine does improve mental and physical performance.
In my last post I wrote about the history of energy drinks and which government regulations impact their manufacturing. This post will report to you more details about research on how energy drinks work and don't work.
For example, an 8-year old study measured how a drink containing taurine and caffeine affected our mental performance and mood. (See explanation of taurine at the end of the post). The non-energy drink group reported reduced feelings of well-being, vitality and socialabiliy while the energy drink group maintained their feelings of well-being.
Many of us take energy drinks to keep us alert during those times when we either aren't getting enough sleep or the event is boring and we're likely to snooze. The problem is that consuming energy drinks as a substitute for sleep eventually leads to sleep deprivation which has disastrous effects. High levels of caffeine may also lead to symptoms such as nausea, increased heart rate, anxiety and restlessness. Moderate caffeine intake does not cause any of these effects.
If you are sensitive to caffeine you need to calculate how much you're taking. Caffeine must be listed as an ingredient on the energy drink so calculating how much you're taking in shouldn't be too complicated.
If you're a parent with teen agers, or younger, drinking energy drinks, you probably also have concerns. Your concern should focus on the amount of sugar in some of these drinks and the amount of calories, which is 200 calories.
Dieters are interested in energy drinks because many studies reported that caffeine elevates the metabolism. More research is needed on that topic and most doctors don't recommend using caffeine as a weight loss tool.
Energy drinks haven't been on the market that long and more research is needed to determine their long-term effects on health and obesity. Although they do improve performance and mood for many people, your experts advise that caffeine consumption should be moderate.
Your comments on energy drinks is welcome. Love to know your favorite drink and why.
And here's the definition of taurine – from Wikipedia
Taurine is an amino acid that keeps potassium and magnesium inside the cell while keeping excessive sodium out. In this sense it works like a diuretic. But unlike prescription diuretics, it is not a cellular poison. Because it aids the movement of potassium, sodium, and calcium in and out of the cell, taurine has been used as a supplementation.
