【medical-news】低盐饮食并不有助于哮喘症状的控
July 15, 2008 -- Cutting back on salt and following a low-sodium diet isn't likely to improve asthma symptoms, according to a new study.
Previous studies had suggested that following a low-sodium diet may help improve asthma control, but researchers now say that advice should be taken with a grain of salt.
"We were disappointed that a simple measure, such as a decrease in sodium intake, does not result in improvements in asthma control," researcher Zara E. K. Pogson, MRCP, clinical research fellow at the University of Nottingham in England, says in a news release. "We therefore cannot advise people with asthma to alter their sodium intake to better control their asthma, despite the fact that a low-sodium diet improves cardiovascular risk factors."
Diet and Asthma Control
Researchers say prior studies on low-sodium diets and asthma control have produced inconsistent results or were too small.
In this study, published in the American Journal of Respiratory and Critical Care Medicine, researchers compared the effects of a low-sodium vs. normal-sodium diet on asthma control in nearly 200 adults with asthma for six weeks. All of the participants followed a strict low-sodium diet and either received sodium supplements equivalent to normal sodium intake or a placebo.
After six weeks, researchers measured control of asthma symptoms and lung function and found no significant differences between the two groups despite the difference in sodium intake.
Researchers say the results suggest that a low-sodium diet provides no additional benefits in improving asthma control.
"This study suggests that further dietary research in asthma should be directed to factors other than sodium," Pogson says.

低钠饮食对哮喘没有影响

2008.7.15-根据一项新近研究，减少盐的摄入和低钠饮食似乎不能改善哮喘症状。
Previous studies had suggested that following a low-sodium diet may help improve asthma control, but researchers now say that advice should be taken with a grain of salt.
以前的研究提示低钠饮食有助于控制哮喘，但是现在研究人员说应该吃一点盐。
"We were disappointed that a simple measure, such as a decrease in sodium intake, does not result in improvements in asthma control," researcher Zara E. K. Pogson, MRCP, clinical research fellow at the University of Nottingham in England, says in a news release. "We therefore cannot advise people with asthma to alter their sodium intake to better control their asthma, despite the fact that a low-sodium diet improves cardiovascular risk factors."
“我们对于那个简单的检测很失望，比如减少钠的摄入并不能有助于控制哮喘。”英格兰诺丁汉大学的临床研究员Zara E. K. Pogson, MRCP在一篇新闻稿中说。“因此我们不会建议那些患有哮喘的人改变钠的摄入，以此来更好的控制哮喘，尽管低钠饮食可以改善心血管危险因子”。
Diet and Asthma Control
Researchers say prior studies on low-sodium diets and asthma control have produced inconsistent results or were too small.
研究者说以前有关低钠饮食和哮喘控制的研究没有得到一致的结果或者得到的结果很少。
In this study, published in the American Journal of Respiratory and Critical Care Medicine, researchers compared the effects of a low-sodium vs. normal-sodium diet on asthma control in nearly 200 adults with asthma for six weeks. All of the participants followed a strict low-sodium diet and either received sodium supplements equivalent to normal sodium intake or a placebo.
发表在美国呼吸和危重病医学杂志上的一项研究中，研究人员利用6周时间在近乎200名患有哮喘的人群中比较了低钠饮食和低钠饮食对哮喘控制的影响。所有的人员都遵循严格的低钠饮食，或者得到钠补充以达到正常钠摄入量或者是使用安慰剂。
After six weeks, researchers measured control of asthma symptoms and lung function and found no significant differences between the two groups despite the difference in sodium intake.
6周后，研究人员检测了哮喘症状的控制情况和肺功能，发现两组人群除了钠摄入不同外，并无显著性差异。
Researchers say the results suggest that a low-sodium diet provides no additional benefits in improving asthma control.
研究者说这些结果提示低钠饮食对于改善哮喘的控制没有什么益处。
"This study suggests that further dietary research in asthma should be directed to factors other than sodium," Pogson says.
