摘要

The salt content of processed foods is important because of the high intake of Na by most New Zealanders. A database of Na concentrations innfifty-eight processed foods was compiled from existing and new data and combined with 24 h diet recall data from two national nutrition surveysn(5771 respondents) to derive salt intakes for seven population groups. Mean salt intakes from processed foods ranged from 6·9 g/d for young malesnaged 19–24 years to 3·5 g/d for children aged 5–6 years. A total of $50% of children aged 5–6 years, boys aged 11–14 years and young malesnaged 19–24 years had salt intakes that exceeded the upper limit for Na, calculated as salt (3·2–5·3 g/d), from processed foods only. Breadnaccounted for the greatest contribution to salt intake for each population group (35–43% of total salt intake). Other foods that contributedn2% or more and common across most age groups were sausage, meat pies, pizza, instant noodles and cheese. The Na concentrations of keynfoods have changed little over the 16-year period from 1987 to 2003 except for corned beef and whole milk that have decreased by 34 andn50% respectively. Bread is an obvious target for salt reduction but the implication on iodine intake needs consideration as salt is used as a vehiclenfor iodine fortification of bread.
