As part of the Food Labeling and Product Surveillance Program of the Food and Drug Administration, samples from 1982, 1984, and 1986 surveys of processed packaged foods (canned, frozen, and dry packaged) were analyzed to determine how closely the foods' actual sodium content matched their label claims for sodium. Samples were classified into three groups: "sodium-free" products (less than 5 mg sodium per serving), and "very-low-sodium" products (5 to 35 mg per serving), and a larger group of products that were labeled as containing more than 35 mg sodium per serving. In the third group, the distribution of actual sodium content fell around 100% of label claims for sodium. For the three survey years, analyzed sodium averaged 101% of label claim (standard deviation [SD] = 25%) for 1982 samples (20 products), 99% of label claim (SD = 28%) for 1984 samples (108 products), and 94% of label claim (SD = 21%) for 1986 samples (265 products). Products labeled "very low sodium" were treated separately because sodium analyses varied widely from the label declarations. However, most "very-low-sodium" products were well under 35 mg sodium per serving. Results indicated that consumers receive reasonably accurate information about the sodium content of processed packaged foods from label claims.
作为美国食品药品监督管理局食品标签与产品监督计划的一部分，对1982年、1984年和1986年加工包装食品（罐装、冷冻和干包装）调查的样本进行了分析，以确定食品的实际钠含量与标签上钠含量声明的匹配程度。样本分为三组：“无钠”产品（每份钠含量低于5毫克）、“极低钠”产品（每份5至35毫克），以及一大组标签上声明每份钠含量超过35毫克的产品。在第三组中，实际钠含量的分布约为标签上钠含量声明的100%。在这三个调查年份中，1982年样本（20种产品）的分析钠含量平均为标签声明的101%（标准差[SD]=25%），1984年样本（108种产品）为标签声明的99%（SD=28%），1986年样本（265种产品）为标签声明的94%（SD=21%）。标签为“极低钠”的产品单独处理，因为钠分析结果与标签声明差异很大。然而，大多数“极低钠”产品每份钠含量远低于35毫克。结果表明，消费者能从标签声明中获得关于加工包装食品钠含量的合理准确信息。
