大家好! 

本周的美国疾控中心（CDC）《减盐电子周刊》包含一份美国零食膳食钠摄入量的新研究报告。 

美国零食膳食钠摄入量 

《Nutrients》杂志发表的一份新研究报告，分析了1977年至2014年零食对钠摄入量的贡献情况。零食对钠摄入的最大贡献发生在最低收入群体和最低教育群体中。从1977年至2014年，最低收入群体中成人和儿童的零食钠摄入从最低水平增长至最高水平。研究期限内，美国成人咸味零食消费量增长了一倍多，儿童咸味零食消费量增长了75%。2014年，百分之二十五的零食钠摄入来自谷物类甜食和咸味零食，非西班牙裔黑人零食钠摄入量高于其他种族群体。本研究发现，1977年至2014年零食钠摄入量呈总体增长趋势，但是在2003-2006年和2011-2014年两个调查时期，源自零食的钠摄入量呈现下降趋势。作者注意到，此研究对美国人口中具体群体的未来政策干预存在影响。

Hello – 

This week’s CDC Salt e-Update includes a new study about dietary sodium intake from snacking in the U.S. 

Dietary Sodium Intake from Snacking in the U.S. 

A new study published in the journal Nutrients examined how the contribution of snack foods to sodium intake has changed between 1977 and 2014.  The largest increase in sodium intake from snacks was seen in the lowest income group and the lowest education group.  Adults and children in the lowest income group went from the lowest sodium intake from snacks to the highest from 1977 to 2014.  Salty snack more than doubled during the study period in U.S. adults and increased by 75% in children.  Twenty-five percent of sodium intake from snack foods came from grain-based desserts and salty snacks in 2014, with Non-Hispanic Blacks consuming a higher intake of sodium from snacks than other race-ethnic groups.  The study found an overall increase in sodium intake from snacking between 1977 and 2014, but noted a declining trend in sodium intake from snacking between 2003-2006 and 2011-2014 survey periods.  The authors noted that their findings have implications for future policy interventions targeting specific demographic subgroups of the US population.
