Avoid Foods That Trigger Asthma

A question that many fail to answer is what causes asthma. What you can answer is that asthma is a chronic condition involving the inflammation of airways and its symptoms differ from person to person. One thing, though, is common in asthma sufferers: when they are exposed to an asthma trigger, their airways become swollen and narrow and are filled with mucous. Therefore, it’s recommended to stay as far away from such symptom-inducing triggers as is possible for you.

When it comes to triggers, one that you can avoid without too many hassles is food. A survey revealed that 70% of the people with asthma are of an opinion that foods can trigger their asthma symptoms. However, if you run a food test on people having asthma, you will find that the prevalence of food-induced asthma is as low as 5%. Despite the low percentage, there is little doubt that some people still show severe allergic reactions to food.

Let’s have a look at the allergies and the foods that cause them.

Common allergies from food proteins

People show immediate allergic reactions to certain food proteins. These foods include fish, nuts, seeds such as sesame, and even milk. Many people allergic to these foods develop swelling in their mouth and throat, some people even collapse. It is quite possible that asthma trigger may follow these reactions. Thus, avoiding these food is recommended. In addition, sufferers can consult their physicians and keep an epinephrine with them as a precaution for such unintended exposures.

Uncommon allergies

If you or an asthmatic patient eat sulfite, also known as metabisulfite or additive 220, which is a common preservative, chances are that you develop wheezing, especially if your asthma is not in control. The wheezing can be followed by an asthma attack ranging from mild to serious potential. This happens because when you eat foods with sulfite, the sulfite converts in a gas called sulfur dioxide. The foods having this chemical that you need to be careful of are salad dressings, dry fruits, sauces, and wine. And if you consume them mistakenly and get a wheeze, you must get your asthma monitored or speak with a specialist.

Rare allergies

Some people are of a belief that foods like yeast, dairy, or wheat products can cause rash, fatigue, asthma, or a headache. Others report of being allergic to additives like food preservatives, colors, etc. These kinds of disorders are also called food intolerance. The cases of such disorders are however very rare and such people can be considered as exceptions.


To prevent yourself from such allergies, you should always keep your asthma under check. Additionally, carry a medication, just in case your asthma goes out of control.

Avoid coming in contact with foods that you are allergic to. It is sometimes tricky as you have to check all the ingredients and labels and ask how the foods is prepared when eating out. Even so, prevention is better than cure, so why not.
