Ok, I'm in France, I can relate because the traditional French food is bread, cheese, meat, etc.. even around mediterranean. I haven't eat bread since years and for fibers, it takes time to transition (your guts bacteria), and also relearn how to masticate efficiently, typically I eat almost everything (seeds for example grapes, melons, watermelons, skin when possible, e.g kiwis, persimmons, grapes, mangoes, many others), I like it more than the juice itself
