Yep, that’s not a problem! Many of our youth travelers are in that boat. Choose a destination that has good food accommodations (this is listed in the faqs section of every trip page) and then make sure you include your food allergies/restrictions on your participant health form and give us an early heads up so that we can notify your in-country hosts.
You will be responsible for monitoring what you eat during your trip, but your awesome trip leaders will be there to help and support you.
