I'm not sure which metric GP is referring to, but by total value of food exports they're 7th in the world. Extremely impressive for a country of only 17 million people.
It's probably because the Dutch diaspora has succeeded in getting their children hooked on stroopwafels (syrup waffles), salt licorice and those amazing dense raisin buns that seem to be approximately 50% raisins... I for one am happy to continue supporting their export economy!
