Is Caffeine Good For You?

coffeeCaffeine itself isn’t terribly harmful – suggestions that caffeine intake is associated with osteoporosis and cancer have been disproven by multiple studies – but not all sources of caffeine should be treated equally.  

The caffeine in coffee and tea is accompanied by healthy antioxidants. Tea, especially green tea, may reduce your risk for developing some types of cancers. Coffee can be used to treat those with liver disease, and may  reduce the risk of developing Parkinson’s disease, heart disease, and type 2 diabetes.

But what about energy drinks? Read on… You might be surprised at what you see!

Energy drinks are marketed as healthy or harmless.

energy drinksEnergy drinks contain caffeine, few to no calories,  are often fortified with vitamins and minerals, and are marketed as a healthier alternative to soda. It’s working: the consumption of energy drinks is on the rise, especially among children, adolescents, and young adults. Because energy drinks are considered dietary supplements, the ingredients are not regulated by the Food and Drug Administration. The very high amounts of  caffeine in these drinks often come from natural sounding ingredients like guarana, taurine, and yerba mate.

In fact, energy drinks are a disaster.

Energy drink consumers report an alarming rate of nausea, vomiting, diarrhea, seizures, heart abnormalities, and mood changes, many of these occurring in children and adolescents.  According to the Center for Science in the Public Interest, at least 34 deaths have been directly attributable to energy drinks since 2012. The natural ingredients are a tiny fraction of energy drink contents and are thus very unlikely to give you any benefit at all. The primary ingredients include carbonated water, sucrose and glucose (also known as sugar). One Monster energy drink can have 13.5 spoons of sugar.

But it may not be the caffeine that’s to blame.

The caffeine levels in energy drinks is often the same (and sometimes less) than a cup of coffee, so the danger stems from something else (or at least not the caffeine in one drink). Many health experts believe consumers are more likely to overdose on energy drinks because they are drank quickly, in larger quantities, and often by children.

For most healthy adults, about 300 – 400 mg of caffeine per day is ok.

What does that look like? Below is a handy chart, thanks to the CaffeineOverdose blog.

This is what 400 mg of caffeine looks like.

The sodas and energy drinks above come with considerable amounts of sugar, so while the caffeine from a coke or two are well within the daily limit, the sugar will quickly surpass healthy levels.

Kids under age 18 should limit their caffeine to 100mg per day. Under age 12, they should avoid it altogether.

While we don’t have clinical studies on the effects of caffeine on the brains of kids (for ethical reasons these can’t be done), caffeine will disrupt sleep and impair concentration. As it disrupts sleep, and sleep is vital to healthy brain development, caffeine can be dangerous for kids.

Adults, stick the to tried-and-true stuff.

Little data exists about energy drink safety so we at Power 20 recommend coffee and teas as a reliable and safe source of caffeine. Caffeine tolerance varies among individuals, there is no recommended maximum limit for caffeine intake. Two to four cups of coffee a day is tolerable by most, but your individual limit may be higher or lower. If you’re experiencing any problems with jitteriness, shakiness, dehydration, or falling asleep at night, this may be a sign that you need to cut back.
