Cut the Carbs

Your tush and your teeth will thank you if you just step away from the carbs. Foods that contain sugars and starches--aka carbohydrates-fuel the bacteria that live inside your mouth. Like we said before, these bacteria produce acids that destroy tooth enamel, which ultimately results in tooth decay and cavities. You don't have to quit the carbs altogether, though: just brush after you eat sugary and starchy foods, and limit snacking between meals.
