Changes in the sodium content of New Zealand processed foods: 2003-2013.

ABSTRACT: Decreasing population sodium intake has been identified as a "best buy" for reducing non-communicable disease. The aim of this study was to explore 10-year changes in the sodium content of New Zealand processed foods. Nutrient data for nine key food groups were collected in supermarkets in 2003 (n = 323) and 2013 (n = 885). Mean (SD) and median (min, max) sodium content were calculated by food group, year and label type (private/branded). Paired t-tests explored changes in sodium content for all products available for sale in both years (matched; n = 182). The mean (SD) sodium content of all foods was 436 (263) mg (100 g)(-1) in 2003 and 433 (304) mg (100 g)(-1) in 2013, with no significant difference in matched products over time (mean (SD) difference, -56 (122) mg (100 g)(-1), 12%; p = 0
