Eating Healthy in Disney World

Hi! I was wondering if I can get some tips on eating healthy at Disney World. My family got the dining plan ( 1 counter service, 1 table service and 1 snack per day) We already have our table services reserved, here is where we are going:

Rose & Crown Pub @ EPCOT
Liberty Tree Tavern @ MK
Boma @ Animal Kingdom Lodge
50′s Prime Time Cafe @ MGM
Crystal Palace Breakfast @ MK
Tony’s Town Square @ MK
and Le Cellier @ EPCOT

Does anyone know how I can eat healthier here? Any suggestion of places that sell fruit, or healthy snacks, or healthier counter services? Thanks in advance.
