Germany's oldest person dies

112 year-old Gertrude Henze of Germany died on April 22,2014.She was the oldest person in Germany.Germany is Western Europe's most populous country.But the oldest living person in Europe is very rarely from Germany.I wonder why.There are far more supercentenarians(people over 110) living in France,Italy and Great Britain than in Germany.Is there something in the German diet that discourages extreme longevity?I am curious.
