Since 1980 General Mills Inc has regularly conducted studies of the mean daily intake of 25 nutrients from nationally representative samples of 4000 American households (approximately 10,000 individuals). This paper examines trends in sodium consumption derived from these studies. Calculated estimates of both discretionary and nondiscretionary intake indicate that overall sodium consumption has declined since the early 1980s. Shifts in food sources of sodium have occurred over the 10-y study period, with the greatest amounts of sodium coming from meats and mixed dishes. Greater interest in the sodium content of the diet is predicted because of the daily value listing on the new food label and the National Heart, Lung and Blood Institute's campaign to reduce sodium intake. Until an acceptable alternative for the salty taste from sodium chloride is available, offering reduced-sodium alternatives and gradually reducing the sodium content of existing products appears to be the food industry's best approach to meet consumers' concerns about sodium.
自1980年以来，通用磨坊公司定期对来自4000个美国家庭（约10000人）具有全国代表性的样本中的25种营养素的平均每日摄入量进行研究。本文研究了从这些研究中得出的钠消费趋势。对自由支配和非自由支配摄入量的计算估计表明，自20世纪80年代初以来，总体钠消费量有所下降。在10年的研究期内，钠的食物来源发生了变化，钠的最大来源是肉类和混合菜肴。由于新食品标签上的每日摄入量列表以及美国国立心肺血液研究所减少钠摄入量的运动，预计人们会对饮食中的钠含量更加关注。在有可接受的替代氯化钠咸味的产品之前，提供低钠替代品并逐步降低现有产品的钠含量似乎是食品行业满足消费者对钠担忧的最佳方法。
