Soy sauce is international. Jugo(maggi) is the common European variant, used in many dishes.
Just FYI. Asian food with soy sauce is only a small bit of 'Asian' food. And the foods vary a lot from region to region. Go to parts of Japan and you wont find any soy sauce, but it might be on the side to please out of town customers. Same with a number of places.
There is just a lot wrong with that statement. I don't think anyone really knows where to begin. But hay, it's your body, you can eat and discriminate against any food you choose. It's just this stereotype that you point out, and I meet a lot of people who think the same. Only to find out how super wrong they are when they actually explore Asian cuisine deeper.
