One week's food for some different cultures

Germany: The Melander family of Bargteheide
Food expenditure for one week: 375.39 Euros or $500.07
My comment: A lot of alcohol pushing up the cost?
 

United States: The Revis family of North Carolina
Food expenditure for one week: $341.98
My comment: A relatively low-budget family by USA standards? They also look slimmer than the average American!
 

Japan : The Ukita family of Kodaira City
Food expenditure for one week: 37,699 Yen or $317.25
 

Italy: The Manzo family of Sicily
Food expenditure for one week: 214.36 Euros or $260.11

Interesting comparison, but perhaps misleading in the position of the USA in this league?
