I think most information now points to energy drinks being unhealthy.
You might already know that energy drinks can screw with your sleep, make you gain weight, or even spike your blood pressure. But overarching evidence suggests they may lead to substance abuse, mental health problems, a higher diabetes risk, tooth decay, and kidney damage, too. Not surprisingly...the sweet stuff may be to blame. Energy drinks typically contain high amounts of added sugar, high-fructose corn syrup, and artificial sweeteners. In fact, an average 500-milliliter/16.9-ounce can contains roughly 54 grams (g) of sugar, the review found, which is well beyond the American Heart Association's recommendation of no more than 36 g per day for men.
