Because you can remove ClearCorrect during meals and snacks, there are no dietary restrictions while you’re undergoing the treatment. That said, you do still need to be careful. Chewing gum is generally not recommended because it can get stuck to the plastic and lead to various problems. For that matter, you need to clean your mouth as thoroughly as possible before putting your aligners back in your mouth; any sugars or acids left behind on your teeth could end up trapped in place, giving them an opportunity to cause some real damage to your enamel.
