Speaking of bro-science, added sugar is chemically equal to naturally occurring sugars and you can't discriminate against one with out the other (either it's healthy or it is not). Hint: It's not. That fruit may have vitamins, but they are basically embedded in a candy bar nutrition wise. Actually, it's worse than a candy bar because it lacks protein and fat which keep you satiated.

Humans evolved to crave sugar for a reason. It's not bad for you. But, as with anything, too much is absolutely bad for you. Fruit has this really great built-in mechanism for stopping you from eating too much: fiber. Added sugar (or removed fiber, in e.g., juice) makes it easy to exceed the healthy amount.
