背景：在英国，许多加工食品类别都设定了减钠目标。评估和监测对于评估进展至关重要。目标：我们的目的是确定家庭消费者小组食品购买数据是否可用于评估加工食品的钠含量。我们的进一步目标是按类别估计英国食品的平均钠含量，并按食品购买量进行加权分析。设计：从 2008 年 10 月至 2009 年 9 月期间获得了 21,108 个英国家庭的数据。对已知对钠摄入量有主要影响的所有食品类别的采购数据（产品说明、产品重量、年度购买量）和钠值（毫克/100 克）进行了整理。计算未加权和加权平均钠值。结果：可获得 44,372 种食品的数据。钠购买的最大贡献者是食盐（23%）、加工肉类（18%）、面包和烘焙产品（13%）、乳制品（12%）以及酱汁和涂抹酱（11%）。超过三分之一 (37%) 的钠购买量来自 5 种食品：培根、面包、牛奶、奶酪和酱汁。对于某些食品类别（面包和烘焙食品、谷物和谷物制品、加工肉类），购买加权平均值比未加权平均值高 18-35%，这表明市场领导者的钠含量高于类别平均值。 结论：以少数食品类别减少钠含量并重点关注销量最高的产品可能会导致可供消费的钠大幅减少，从而改善公共健康。美国临床营养杂志 2011；93：594-600。
Background: In the United Kingdom, sodium reduction targets have been set for a large number of processed food categories. Assessment and monitoring are essential to evaluate progress.Objectives: Our aim was to determine whether household consumer panel food-purchasing data could be used to assess the sodium content of processed foods. Our further objectives were to estimate the mean sodium content of UK foods by category and undertake analyses weighted by food-purchasing volumes.Design: Data were obtained for 21,108 British households between October 2008 and September 2009. Purchasing data (product description, product weight, annual purchases) and sodium values (mg/100 g) were collated for all food categories known to be major contributors to sodium intake. Unweighted and weighted mean sodium values were calculated.Results: Data were available for 44,372 food products. The largest contributors to sodium purchases were table salt (23%), processed meat (18%), bread and bakery products (13%), dairy products (12%), and sauces and spreads (11%). More than one-third of sodium purchased (37%) was accounted for by 5 food categories: bacon, bread, milk, cheese, and sauces. For some food groups (bread and bakery, cereals and cereal products, processed meat), purchase-weighted means were 18-35% higher than unweighted means, suggesting that market leaders have higher sodium contents than the category mean.Conclusion: The targeting of sodium reduction in a small number of food categories and focusing on products sold in the highest volumes could lead to large decreases in sodium available for consumption and therefore to gains in public health.
