Traditional French cuisine is reputed to be a fat cuisine. This
is of questionable truth, certainly not generally true for modern
French cuisine, and certainly never was a unique aspect of French
cuisine.
Other aspects of French cuisine include its diversity,
inventiveness, or the nation's passion with its cuisine, none of
which is unique to French cuisine. Both, those attributes might be
cited as characteristics of French cuisine.
Any region's cuisine evolves with disregard of political
boundaries. Adjacent countries will almost always share many of the
characteristics with a specific country's traditional cuisine,
rendering any claim of "traditional cuisine of country X"
questionable.
For example, the cuisine in the south-west of France is very
similar to northern Spanish cuisine, while eastern French cuisine
shares similarities with German, Swiss and Italian cooking.
