I met an asthma sufferer today who didn't know that cutting down on salt/sodium is helpful for people with asthma, so I thought I'd draw attention to this again.
A crucial dietary measure that reduces the incidence and severity
of childhood asthma is to avoid feeding children salty meals and snacks.
- See this article,
where you will read, "According to a new study published in the
American Dietetic Association, high-salt foods and snacks are linked to
lung changes that trigger asthma symptoms.," and that researchers in
Greece found, using questionnaires, "Kids who ate high-salt foods more than three times a week saw their risk of asthma symptoms go up almost five times."
We read in this Telegraph report
of research in Rome, Italy, led by Dr Giuseppe Corbo. "The study of
20,000 six and seven-year-olds, published in the medical journal
Epidemiology, confirmed a strong link with asthma and obesity, but found
that salt was the biggest risk. Those with the highest intake were two and a half times more likely to develop asthma." (My emphasis)
If an asthma sufferer uses or has ever used a steroid inhaler it is even more helpful to reduce salt intake. This is because prescribed steroids can, and usually do, cause salt sensitivity/sodium retention/water weight. - See Prescribed Steroids. And for information about the salt content of foods, see Sodium in Foods.
