LOS ANGELES (KABC) — Caffeine is the most widely used drug in the world. Over 90% of American adults consume caffeine regularly. However, there are both benefits and risks associated with using this popular stimulant.
Recent test finds that caffeinated drinks may put people with genetic heart problems at risk for heart events like arrhythmias. But even for the general population, caffeine is best in measured doses.
Caffeine stimulates and energizes, but many coffee lovers may not understand the pros and cons of caffeine.
On the positive side, caffeine can improve your performance during endurance exercise. It can also speed up weight loss by temporarily suppressing your appetite and helping your body produce more energy when digesting food.
Research from Johns Hopkins University shows it can also sharpen long-term memory. And one study found that caffeine applied directly to the skin of mice helped prevent skin cancer caused by UV radiation. Caffeinated beverages, such as coffee, contain powerful antioxidants.
“There are studies that actually show a lot of nutritional benefits of coffee,” said dietitian Ashley Hinds.
Various studies have shown that coffee consumption can reduce the risk of developing certain cancers, diabetes, stroke, Parkinson’s disease and other conditions. However, too much caffeine can have negative consequences.
“I’m always aware that caffeine can actually boost our anxiety and disrupt our sleep cycles,” Hinds said.
Caffeine can also affect fertility. According to a study published in the British Journal of Pharmacology, caffeine can reduce a woman’s chances of getting pregnant by about 27%. And women who consume caffeine during menopause are more likely to experience warm flashes and night sweats. Experts typically recommend no more than 400 milligrams per day—that’s about four 8-ounce cups of coffee.
The American Academy of Pediatrics says children under 12 should avoid caffeine. People aged 12 to 18 should consume no more than 100 milligrams of caffeine per day, and experts recommend pregnant women consume no more than 200 milligrams per day.
