I love to eat and read - must be an expert on that particular subject!
If I'm cooking and using the Kindle (either to listen to an audiobook or viewing my personal recipe document) then I place it in a clear plastic bag so when I inevitably touch it with sticky fingers, only the bag gets messed up - not my Kindle!
Eating in the bath (a luxury which doesn't happen enough with having a hyper 3 year old!) then I use a waterproof bag because I have been known to drop paper books in the bath - at least they still "work" afterwards however crinkled!
For full-on eating while reading, I use the Kindle in "hands-free" mode on a book stand so I don't need to press anything:

With the odd dry snack such as a chocolate bar, I just hold the Kindle in my right hand so I can operate it fully and eat with the other hand. Crumbs can be wiped away with a very soft brush.
No reason why you can't indulge in your favourite things whilst Kindling
