Health and dietary monitoring has a long history in Finland. The aim of this review is to summarise the main sources of Finnish dietary information including food balance sheets, household budget survey data, questionnaires related to dietary behaviour and risk factors of main chronic diseases as well as dietary surveys. According to these sources, dietary behaviour and food choices have changed considerably during the last decades. For example, the total fat intake (E %) has decreased remarkably from nearly 40 % in the late 1960s to close to 30 % in 2007. Furthermore, the type of fat consumed has changed noticeably due to the increased popularity of oil used in cooking and the large variety of softer spreads available. There has also been a notable decrease in intake of salt, and a multiple increase in the consumption of fruits and vegetables since the 1970s. The future challenges of dietary monitoring include keeping the participation rates in dietary surveys at acceptable levels, controlling under/over-reporting of diet, developing a national monitoring system for children and adapting to international changes and requirements to harmonise dietary monitoring in Europe.
