Diet Soda
The word "diet" doesn't always equal healthy, and that's certainly the case for diet soda. Made with artificial ingredients and flavorings, it's not only unnatural and high in sodium, but regular diet soda drinkers have been shown to eat more calories after consuming diet cola. While the reasons aren't fully understood, researchers suspect it's the body's way of making up for calories it thinks it received in the diet soda but didn't.
