nuts

I have been wondering of late about mixed nuts, specifically about the ratio of one type of nut to the other in the mixture… for instance, is the ratio regionally dependant… do the nut mixes have more of one of the other type of nut if a certain kind of nut grows more prevalently in a given location?... if we looked at the contents of a box of nuts from france, for instance, would it be consitutionally different than a box of nuts from china?... would there be differences in the constituency of nuts from north korea, india, iraq, isreal, south africa, new zealand, canada, or chile?... I think someone should travel the world to explore the many different varieties of nuts and see how they mix…
