The analysis of influence of predominantly choosing specific fish species on total vitamin D intake from food, conducted based on the analysis of correlation between vitamin D intake from fish and total dietary vitamin D intake from food, and the comparison of vitamin D intake among participants choosing specific fish species or not.
