| Riassunto: | We aimed to compare the mean sodium content of New Zealand (NZ) packaged breads in 2013 and 2023 and assess compliance with the NZ Heart Foundation (HF) and World Health Organization (WHO) sodium reduction benchmarks. Sodium data were obtained from a supermarket food composition database. Mean differences between years were assessed using independent samples t-tests and chi-square tests. There was a significant reduction in the sodium content of all bread from 2013 (n=345) to 2023 (n=309) of 46 mg/100g (p<0.001). In 2013, 20% (n=70/345) of breads met the HF benchmarks, and 10% (33/345) met the WHO benchmarks; corresponding values for 2023 were 45% (n=138/309) and 18% (n=57/309) (p<0.001 for both). If continued, the modest reduction in sodium content and increase in the percentage of NZ breads meeting relevant sodium reduction benchmarks could positively affect public health, particularly if extended across the packaged food supply. |
