The country/location is already detected and used before you get to the nutrition facts page. In the url I gave, it includes "/us/en-us/". As the other commenter to my comment saw, going to that url in Sweden gives the US nutrition facts, not their local ones. Given the location isn't used to customize the results, nor provide any information on where restaurants are or availability, what do you believe the end user's benefit is?
