Well this is an interesting one. For me the main reason why I like Asian foods so much when I am there I because of the fresh greens. Last year when I was in Vietnam I think lost like 5 kilos in three weeks or something, and that was not because of any food poisoning or so.
Here in Europe it is super challenging to get foods that are not overly processed. Even the decent stuff like olive oil is literally a jungle or all fabricated and refined oil (aka garbage) and for looking for the decent wone it might take you some time.
The market for me is the place to be in Asia, but when I had to my market here..it is still entirely with fast growth chicken and sprayed veggies. To me it is even worse that in the most places in Vietnam.
I guess just that stuff is fresh and homegrown, that makes all of the difference
