Isn't bread with milk and egg in it called brioche?
Most challah contains egg but no milk, so observant Jews can eat it with meat or poultry.
I sometimes put olive oil in bread, but never milk or egg. I do put egg in some dough, especially for things like empanadas or calzones, to make it more elastic. But not much.
I agree that there are problems with our food industry, but some of the sources North has quoted seem cranky or poorly researched.
I'm proud to say I've never eaten a Michelina's. They do have attractive (misleading) packaging, but I've seen people eating them and they look sad indeed. Pasta is so quick and easy to cook. I certainly don't want to ban them or other junk (except perhaps from schools) but the sad thing is food deserts where there are few fresh options. There are local people working on this here as elsewhere.
