Objective: To gauge the effect of different migration periods on the eating pattern of Portuguese university students.Methods/subjects: Fifty-five Portuguese students participated in a survey of food practices before and after moving from Portugal to London. The students were divided into two groups, the short term migration group, living in London less than one year, and the long term migration group, living in London more than one year. Forty-six English university students were used as a comparison to the Portuguese students. A questionnaire was administrated to assess the frequency of eating selected food, factors which may influence food choice and food preparation and purchasing behaviours.Results: After moving to London, the long term migration group adopted more dietary changes and seems to become more acculturated. Both Portuguese groups reported significant decrease in the weekly frequency of consumption of raw vegetables, fish, vegetable soup and red meat. The frequency of the consumption of savoury snacks, fast food and ready prepared meal increased and was similar to the English students' consumption.
Conclusion:These findings highlight the difficulties that Portuguese students faced in maintaining a traditional Mediterranean diet after moving to a Northern European environment.
