This is an area that is undergoing a lot of research at the moment and what we have seen so far is that there really is no clear link between certain foods causing or triggering asthma attacks.
There is an old wives’ tale that drinking milk is linked to asthma but the evidence shows that unless you have an allergy or intolerance to milk, cutting it from your diet won’t do anything to improve asthma symptoms. Likewise, the evidence doesn’t support a link between food additives such as dye and preservative and asthma attacks.
What we do know is that someone with a food allergy is more likely to also have asthma, so if your son does have any food allergies then it is very important these are managed properly. Being overweight or obese increases the likelihood of asthma attacks, so keeping your son at a healthy weight will help him to manage his condition.
