One of the surprising health benefits of caffeine has to do with stroke risk. Previously, it was thought that coffee consumption might increase your risk for stroke. But a recent study of 83,000 women published in Circulation, the journal of the American Heart Association, found that the women who drank more coffee had a slight decrease in their overall stroke risk.

5. Caffeine may also help treat ADHD.

Another area where the perception of caffeine is changing is attention deficit hyperactivity disorder, or ADHD. Once thought to be a cause of ADHD, caffeine is now thought to be a potential treatment for the disease because, in moderate doses, caffeine enhances the ability to focus. Although more research on the topic is still needed (please talk to your doctor before trying this), one mom made headlines last year when she announced that her second-grade son drinks coffee twice daily as an effective treatment for his ADHD — and she pointed out that she’s far from the only parent trying it.

6. Sorry, but caffeine may not help you lose weight.

Although many people think of zero-calorie coffee as a diet aid, research has not confirmed that coffee can boost weight loss. “Caffeine can speed up metabolism, resulting in a few more calories burned throughout the day,” Batayneh says. “But high intake of caffeine can also lead to the production of cortisol, the ‘stress hormone,’ which has been linked to weight gain and, of course, stress.” Plus, most studies have found that the increased calorie burn from caffeine is not enough to produce real weight loss.

7. Just put the energy drink down. Now.

When it comes to choosing your sources of caffeine, our experts almost unanimously voted in favor of the natural sources of coffee and tea over the potentially dangerous amount of caffeine, sugar, and other additives in sodas and energy drinks. “Coffee and tea, in moderate doses, contain many antioxidants and a respectable amount of caffeine, offering both feelings of alertness, increased mood, and long-term health benefits,” Batayneh says. “Energy drinks, energy shots, and sodas are manufactured to provide quick boosts of energy with little nutritional benefit,” Batayneh also warns. “Some energy drinks can contain as much as 70 grams of sugar — the equivalent of 17.5 teaspoons.”

Worse yet, energy drinks and shots can be dangerous because of their unnaturally high levels of caffeine combined with ingredients such as guarana (a stimulant), taurine (an amino acid that regulates energy levels and heartbeat), and ginseng (a root that is believed to increase energy). “Ingesting all of these at once can lead to caffeine toxicity, in which an irregular heartbeat, jitteriness, and irritability take over,” she adds. “These ingredients can also interact with prescription drugs and antibiotics, decreasing their effectiveness and possibly causing other harmful side effects.”

8. Inhalable caffeine?

From caffeinated gum to energy shots to drinks, manufacturers are constantly dreaming up new ways to ingest caffeine. One of the newest and buzziest methods on the market is the inhalable caffeine supplement AeroShot, a lipstick-sized container that contains B vitamins and 100 mg of caffeine, which is the equivalent of a large cup of coffee. To take an AeroShot, consumers simply inhale a fine powder that instantly dissolves in their mouth.

Created by David Edwards, a biomedical engineering professor at Harvard University, AeroShot is currently available in Massachusetts, New York, and France. That might change, however, as the substance is now up for a safety review by the U.S. Food and Drug Administration. Recently, the FDA issued a warning to the drug’s manufacturer, Breathable Foods Inc., calling the product’s current labeling false, misleading, and potentially dangerous. The agency has taken no further steps to remove AeroShot from the market.
