During the 10 years of monitoring, the mean plasma vitamin C concentration among men ranged from 2\u00b75 to 8\u00b70 \u03bcmol\/l in Pitk\u00e4ranta, Russia and from 27\u00b71 to 53\u00b79 \u03bcmol\/l in North Karelia, Finland. In both areas, daily consumption of fruit was most strongly associated with plasma vitamin C, while the association of fresh vegetable consumption with plasma vitamin C was less consistent. Consumption of berries was less important in explaining plasma vitamin C. In Pitk\u00e4ranta, the plasma vitamin C concentration was lower among respondents in the lowest education group.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980013002243_abs6\" sec-type=\"conclusion\"><jats:title>Conclusions<\/jats:title><jats:p>Differences in the consumption of fresh vegetables and fruit resulted in notable differences in vitamin C status between Pitk\u00e4ranta and North Karelia in spring.
