Depending on where I'm living, I've struggled with this too. It's difficult in some cities/countries/cultures. I've found that, in most places, it's normally possible to find eggs produced by free-range chickens (ironically, typically at the extreme of fancy super markets or really poor ones). Milk I've been off for a long time, though I confess to enjoying a pizza once every couple months or so. I can normally avoid it though. Soy/tofu/tempeh, oats, nuts, legumes and quinoa are my major sources (quinoa can be hard to find though). I imagine soy-products might be less popular in Brazil?
