In fact it is probably safer to eat/bring your own food when travelling. Our bodies grow accustomed to whatever local microbes we normally encounter and different ones can cause various upsets. All the warnings you used to hear about not drinking the water if you travelled to Mexico are a fine example, nothing wrong with the water there, just different.
Now all that said I am not sure what the point of travel is if you don't sample the local food. (just be prepared for a tummy ache or 2)
