大家好！
本周美国疾病预防控制中心《减盐电子周刊》内容包括：有关减钠的最新研究。
钠和钾的摄入量不平衡
一项题为《钠和钾的摄入量不平衡：对饮食行为的影响》的最新论文，讨论了钠和钾的建议摄入量、钠和钾的食物来源、钠钾比例及对饮食实践的影响。论文发表于《美国营养学会杂志》，可通过下列链接找到：http://www.sciencedirect.com/science/article/pii/S2212267214001932。
食品零售环境下的钠和钾
一项新研究的作者们使用从8779名20岁以上成人中采集的数据，评估了在美国成年人当中，当地食品零售环境与钠和钾的摄入量之间的关系。在2005-2008年间开展的全国健康和营养调查（NHANES）中，参与者完成了不少与24小时的膳食回顾。他们采用修改后的食品零售环境指标（mRFEI）评估了食品零售环境，该指标代表了统计区0.5英里距离内健康食品供应商的百分比。结果表明，钠摄入量与食品环境没有关系，mRFEI和钾摄入量以及钠钾比例之间的关系根据地区的不同而不同。
《附近食品零售环境与美国成年人钠和钾摄入量之间的关系》发表在《慢性疾病预防杂志》，可在下列链接找到：http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4008950/。
消费者对学校食堂减钠政策的支持
一项新近发表在《儿童营养管理和实践杂志》的研究，评估了消费者对学校为降低食堂食品中的钠含量所采取政策的支持度，结果发现90%的受访者支持学校为降低食堂食品中的钠含量所采取的政策。研究作者们所分析的数据来自于2010年全国邮件样本调查中9634名18岁及以上成人对有关钠和学校食品中钠含量的一般性问题的回复。

Hello –
This week’s CDC Salt e-Update includes new research on sodium reduction.
Imbalance of Sodium and Potassium Intake
A new paper entitled, “The Imbalance of Sodium and Potassium Intake: Implications for Dietetic Practice” discusses recommendations for sodium and potassium intake, food sources of sodium and potassium, the sodium to potassium ratio, and implications for dietetic practice. The paper, published in the Journal of the Academy of Nutrition and Dietetics, may be found here: http://www.sciencedirect.com/science/article/pii/S2212267214001932.
Sodium and Potassium in the Retail Food Environment
Authors of a new study assessed the relationship between the local retail food environment and sodium and potassium intake among US adults using data from 8,779 participants aged > 20 years. Participants completed at least one 24-hour dietary recall in the National Health and Nutrition Examination Survey (NHANES), 2005-2008. The retail food environment was assessed using the modified Retail Food Environment Index (mRFEI) representing the percentage of healthful-food vendors within a 0.5 mile distance of a census tract. Results indicate that sodium intake is not associated with the food environment and the association between mRFEI and potassium intake and the sodium-potassium ratio varies by region.
The study entitled, “Association of the Neighborhood Retail Food Environment with Sodium and Potassium Intake Among US Adults” and published in the journal Preventing Chronic Disease, may be found here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4008950/.
Consumer Support for Policies to Reduce Sodium in School Cafeterias
A new study published in the Journal of Child Nutrition Management and Practice assessed consumer support for policies lowering sodium in school cafeteria foods and found that 90% of respondents support policies that lower the sodium content of cafeteria foods in schools. Study authors analyzed data from 9,634 adults aged >18 years who responded to general questions about sodium and about sodium in school foods as part of a 2010 national mail panel survey.
The study entitled, “Consumer Support for Policies to Reduce the Sodium Content in School Cafeterias” may be found here: http://www.schoolnutrition.org/Content.aspx?id=20319.
Thank you for your continued engagement in sodium reduction.
