14. Potato Chips
This may come as no surprise, but potato chips are incredibly unhealthy—even if they are also incredibly tasty. They generally tend to have excessively high sodium content, as well as artificial flavoring, coloring, and preservatives. All these together cause you to experience weight-gain and could cause high blood pressure and certain cancers. So, the next time you are looking for a quick, tasty snack, it may be better to choose a healthier, more natural alternative.
