Carbonated drinks


I was wondering if anyone else has noticed a difference in their asthma if they stop drinking carbonated drinks (coke, pepsi,lemonade etc etc)

I had a habit of drinking these types of drink direct from the bottle or can and since i stopped and started drinking water or still drinks my wheezing has reduced dramatically

I have tried to find out if any research has been done into this problem and am still waiting for answers back

Many hospitals are now recommending reduced salicylate and sulphate diets for many asthmatics, especially atopic. Carbonated drinks contain high levels of both I believe so that could be why.

Try the links below they may help you spot more patterns, certainly not a cure all but can and does make a difference.



All the best



Oh that's really interesting! I drink a lot of pepsi max........


i could have understood it the other way round as caffine is a mild bronchodilator so should open the airways up a bit, lol


Hi George,

A sensitivity to sulphites (not a true allergy as such) has been implicated in causing asthma flare ups. My specialist unit have asked me to keep a diary of food/drink and symptoms as the cumulative effect of too many sulphites can, in sensitive people, cause problems.

Might be worth keeping a little diary?
