SUGARY Coke has long been the bane of dentists, but now doctors can get in on the action with the introduction of Coca-Cola Blak. The newest Coke beverage is a fusion of the brand’s signature soda and coffee.

Sugar and caffeine – can’t wait to see that crash.

The sweet liquid – packaged in the classic 8-ounce glass bottle, only with mottled-black tint – has approximately the same caffeine content as a cup of coffee.

The drink, which just hit stores, is being marketed to adults as an energy drink to compete with the likes of Red Bull and SoBe. Just like them, it tastes like crap. And as bad as it tastes, it’s worse for you.

“A cup of coffee isn’t that bad for you. The soda is much worse for you; it’s got like 14 teaspoons of sugar in it,” says Dr. Joel Fuhrman, a family physician who specializes in nutritional medicine. “But the Coke Blak is like a double whammy – the toxicity of the caffeine and the fact that caffeine makes you eat more. It’s a bad idea.

“Basically, what they’ve done is take an unhealthy food and hooked it into caffeine, which makes us unable to stop drinking it.”
