Eating fruit and vegetables is important but not universally followed. This is an interesting study on changes in fruit and vegetable consumption in Finland over 23 years.
Studies from different time periods have shown that consumption of vegetables is more common in higher socioeconomic groups and among women. This study by Roos et al looks at changes of socioeconomic differences in vegetable consumption over time. They examined whether socioeconomic differences, measured by educational level and household income, in daily vegetable consumption have increased, decreased or been stable over the last two decades among Finnish men and women.
Daily consumption of fresh vegetables increased during the study period. Daily consumption of fresh vegetables was more common among those with higher education and higher income during the whole study period. Both educational level and household income differences in daily vegetable consumption slightly narrowed since 1979 among men and women.
Women with high socioeconomic position have been initial trend setters, but the prevalence of daily consumers of vegetables in these groups has not increased since the early 1990s. The prevalence of daily consumption of fresh vegetables has increased more in lower educational and income groups during the 1980s and 1990s along with narrowing socioeconomic differences.
