In 2006 the UK Food Standards Agency (FSA) introduced voluntary sodium reduction targets for more than 80 categories of processed food. Our aim was to determine the impact of these targets on the sodium content of processed foods in the UK between 2006 and 2011.
Household consumer panel data (n>18,000 households) were used to calculate crude and sales-weighted mean sodium content for 47,337 products in 2006 and 49,714 products in 2011. Two sample t-tests were used to compare means. A secondary analysis was undertaken to explore reformulation efforts and included only products available for sale in both 2006 and 2011.
Between 2006 and 2011 there was an overall mean reduction in crude sodium content of UK foods of -26 mg/100g (p ≤ 0.001), equivalent to a 7% fall (356 mg/100g to 330 mg/100g). The corresponding sales-weighted reduction was -21 mg/100g (-6%). For products available for sale in both years the corresponding reduction was -23 mg/100g (p<0.001) or -7%.
The UK FSA voluntary targets delivered a moderate reduction in the mean sodium content of UK processed foods between 2006 and 2011. Whilst encouraging, regular monitoring and review of the UK sodium reduction strategy will be essential to ensure continued progress.
2006 年，英国食品标准局（FSA）为超过 80 类加工食品设定了自愿减钠目标。我们的目的是确定这些目标对英国 2006 年至 2011 年间加工食品中钠含量的影响。
利用家庭消费者小组数据（超过 18000 户家庭），计算了 2006 年 47337 种产品和 2011 年 49714 种产品的粗钠含量和销售加权平均钠含量。采用双样本 t 检验比较平均值。进行了二次分析以探索配方调整工作，仅包括 2006 年和 2011 年均有销售的产品。
2006 年至 2011 年间，英国食品的粗钠含量总体平均降低了-26mg/100g（p≤0.001），相当于降低了 7%（从 356mg/100g 降至 330mg/100g）。相应的销售加权降低了-21mg/100g（-6%）。对于两年均有销售的产品，相应的降低了-23mg/100g（p<0.001）或 7%。
2006 年至 2011 年间，英国 FSA 自愿目标实现了英国加工食品中钠含量的适度降低。虽然令人鼓舞，但为确保持续取得进展，需要对英国减钠战略进行定期监测和审查。
