Hey there Mandy,
Welcome to planDisney and thanks so much for your question! I'm happy to hear that you and your party are planning ahead for your upcoming trip to the Disneyland Resort.
When it comes to special dietary requests, my go to source is the
Special Diet Requests page on the Disneyland Resort website. This page is a really great place to find more information that will help you plan for your trip on topics like dining accommodations, online menus, and more.
For your specific question, I'd recommend emailing Special.Diets@Disneyland.com so that a Cast Member can assist you in finding out ingredients and sugar content for items like the no sugar added ice cream. They should be able to help answer specific questions and point you to additional resources if needed.
Additionally, as you continue to plan your trip, make sure to check the
Disney Parks Blog for articles on all the fun things happening around the Happiest Place on Earth during your visit!
Thanks again for your question, Mandy. I hope you and your party have a great time visiting the Disneyland Resort.
Have a Magical Day,
Greg
