Background
The consumption of 400-600 grams per day of fruits and vegetables has been
linked to reduced risk of cardiovascular disease, and lower incidence of cancers
and chronic diseases. This study explores the alignment of household
purchases of fruits and vegetables with nutritional recommendations in
Switzerland.
Methods
The Swiss Household Budget Surveys for 2006-2008 are analyzed to estimate
the availability of fruits and vegetables at household level after accounting for
food waste. A household is defined as meeting the recommendation when the
monthly purchases by weight are equal or superior to the amount required to
provide three servings of vegetables and two servings of fruits per person per
day.
Results
The descriptive statistics demonstrate that close to 90% of households fail to meet the vegetable
recommendation, and 76% fail to meet the fruit recommendation when unavoidable waste is deducted. These
percentages increase further when total waste (unavoidable, possibly avoidable, and avoidable waste) is
deducted from household purchases. Moreover, a significant association is observed between the structure of
the households and the availability of fruits and vegetables. Families with children are less likely to meet the
recommendations than other types of households.
Conclusions
This paper reveals a need to improve the availability and accessibility to fruits and vegetables, particularly in
households with children. It also highlights the importance of limiting avoidable food waste at household
level. Interventions such as introducing price subsidies on fruits and vegetables, and educating the public on
the importance of limiting household food waste, are recommended.
