It's fine to drink sports drinks to rehydrate.

We all know that soda and similarly sugary drinks like lemonade are bad for us (right?), but what about sports drinks like Gatorade or Powerade? Sports-focused advertising has successfully convinced a whole lot of people that downing a bottle of this stuff is fine, especially if you've gone for a jog recently — it's replacing electrolytes, after all.

But really, for most people the amount of sugar in these drinks is far more than is needed — even if you've been exercising. Lower calorie options, which many of the same companies have created in recent years, are much better options. Or just drink water.
