Folks who are privy to following a special diet (or any kind of modified lifestyle, whether it is medically-driven or by choice) are often accustomed to having be prepared in advance. Our luggage is often indicative of that… I know that when I travel, my suitcase is probably 40% full of food/medications to get me through my trip!
Lucky for us, Disney World covers a lot of our needs. There are plenty of safe food options, loads of snack choices, and they’re pretty good at stocking the necessities in gift shops and stores around the World. Plus, it’s within driving distance to various grocery stores (including a Whole Foods Market), so in the worst scenarios, you’re likely taken care of.
