Background and aims
Background
� There is little if no information regarding dietary trends
in Switzerland in the long term.
Aims
� Assess trends in food availability in Switzerland, in
comparison with its immediate neighbors (Austria,
France, Germany, Italy), for the period 1961-2007.

Methods
� Food and Agricultural Organization food balance
sheets from Austria, France, Germany, Italy and
Switzerland (http://www.fao.org/).
� Food commodities supply for a given country is
estimated taking into account total production,
imports, exports and stocks of food as well as its non-
food use. The resulting yearly supply is then divided
by the average population and the number of days of
the corresponding year to obtain an estimate of the
daily food available per capita.

Conclusion
During the period 1961-2007:
� Changes in food availability in Switzerland were less
pronounced than in their neighboring countries (EU
agricultural policy?)
� Total caloric availability declined slightly.
� Fat content in the diet increased.
� The types of fat available changed (food industry?).
� The types of fruit available changed (globalization?).
The Public Health impact of these changes remain to be
evaluated → next step.
