My 7 year old won't eat?

We're thinking its travel sickness but talking to her it seems she's convinced herself is she eats. She'll be sick. Since Thursday she's been eating very little. Literally a few bites before she says she has a tummy ache or she's full. Even if its her favourite foods. I've tried talking to her saying its travel sickness not food that made her ill and she'll be even more ill if she doesn't eat but it's not working. I'm not sure what to do i dont want it to turn into a eating disorder. What can i do?
Thank you
