Hi Kellyjo,
Welcome to the Disney Parks Moms Panel! Focusing on whole foods and organics is such a great idea for your family but it can become complicated when traveling. Fortunately, Walt Disney World is a champion of having healthy food choices. You didn't say what your specific needs were, so I want to share some resources with you.
Walt Disney World restaurant menus can be found through the
Dining page. I also love the Disney Food Blog. It isn't an official Disney web site, but it has great information about all of the food available at Walt Disney World.
There are grocery delivery services if you need to order some basic items for your family. Garden Grocer does have a fee but they will deliver to your resort to save precious vacation time.
Please let me know if I can answer any other questions for you.
Wishing you a magical vacation,
Amy H.
