10 Foods That Can Trigger Asthma

If you have asthma, then you know that there are certain foods that can trigger an attack. The good news is that by knowing which foods to avoid, you can take steps to prevent an attack from happening. In this blog post, we will discuss 10 of the most common food allergens that can cause problems for people with asthma. Stay safe and healthy by avoiding these foods!

What is Asthma

Asthma is a chronic lung condition that causes difficulty breathing. People with asthma have sensitive airways that can become inflamed and narrow, making breathing difficult. Asthma attacks can be triggered by factors such as pollen, dust, smoke, and sometimes food.

There are two types of asthma: allergic and non-allergic. Allergic asthma is caused by an allergy to a particular substance, such as food. Non-allergic asthma is not caused by an allergy but may be triggered by factors such as cold air, exercise, or emotional stress.

Asthma can be a difficult condition to live with, but there are treatments available that can help manage the symptoms. If you think you or your child may have asthma, it is important to see a doctor for a diagnosis. With proper treatment, people with asthma can live normal, active lives.

Food That Can Trigger Asthma

When it comes to asthma, there are a few things that can trigger an attack. Some of these triggers are environmental, such as pollen or pet dander. Others have to do with lifestyle choices, such as smoking. But did you know that some foods can trigger asthma? Here are ten of the most common offenders.


Eggs are one of the most common triggers of food-induced asthma. They are one of the top eight allergens listed on food labels in the United States. Eggs can trigger asthma and cause other allergic reactions. When you eat eggs, your body may produce antibodies to the egg proteins. These antibodies can cause symptoms such as wheezing and difficulty breathing.

If you have asthma and are allergic to eggs, there are some steps you can take to avoid an asthma attack. Talk to your doctor about your allergies and develop a plan to avoid triggers. When cooking, use egg substitutes or recipes that don’t require eggs. Be sure to read food labels carefully to avoid products that contain eggs.


Shellfish are a common trigger for asthma attacks. If you have asthma, it’s important to avoid shellfish and other seafood that may contain high levels of histamine and other chemicals that can trigger an attack. Some people with asthma may be able to eat cooked shellfish without any problems, but it’s best to talk to your doctor before trying it.


Aside from shellfish, fish is one of the foods that can trigger asthma. This is because fish contains a type of protein called parvalbumin. Parvalbumin is known to cause allergies in some people and can trigger an asthma attack in people who are already sensitive to it. If you have asthma, it’s important to talk to your doctor about whether or not you should avoid fish.

In some cases, it may be possible to eat fish that has been cooked in a way that reduces the amount of parvalbumin present. However, it’s always best to err on the side of caution and avoid fish altogether if you have asthma.


Sulfites are a type of preservative that’s often found in dried fruits, wine, and processed foods. For some people with asthma, they can be a real trigger. If you’re sensitive to sulfites, try to avoid them as much as possible. If you come into contact with them, ensure your inhaler is handy.

While sulfites can be a real pain for asthmatics, there are ways to avoid them. Be sure to read labels carefully and watch out for processed foods. And of course, if you’re ever in doubt, always consult your doctor. With a little bit of effort, you can avoid sulfites and keep your asthma under control.

Tree Nuts

While most people think of nuts as being a healthy snack, it’s important to remember that they can trigger asthma. Sometimes, even a small amount of nut dust can cause an asthma attack for those with asthma. In fact, according to the Asthma and Allergy Foundation of America, tree nuts are one of the top eight allergens that can trigger an asthma attack. If you have asthma, it’s important to avoid all nuts, including cashews, pistachio, almonds, and pecans.


Wheat is a common allergen that can trigger asthma attacks in some people. While the exact mechanism is not fully understood, it is thought that the proteins in wheat may irritate the airways and cause inflammation. Wheat is found in many foods, so it can be difficult to avoid if you have asthma. However, there are some steps you can take to minimize your exposure.

If you have asthma and are allergic to wheat, it is important to avoid foods that contain wheat. This includes bread, pasta, cereals, and baked goods. You should also avoid processed foods that may contain wheat as an ingredient. When dining out, be sure to ask about the ingredients in the food and whether it contains wheat.


Soy is a common food allergen that can trigger asthma. Soybeans are a member of the legume family, which also includes peanuts and peas. Soybeans are used to make many foods, including tofu, soy milk, soy sauce, and tempeh.

Soy can trigger asthma symptoms in two ways: food allergy or intolerance. A food allergy occurs when the immune system overreacts to a protein in the food. This reaction can cause symptoms such as hives, wheezing, and difficulty breathing. On the other hand, intolerance to soy is not an immune reaction. Instead, it is a reaction to chemicals in soybeans that can irritate the lungs and trigger asthma symptoms.

Cow’s Milk

When it comes to dairy, cow’s milk is one of the most common triggers of asthma. In fact, it’s been shown to trigger asthma symptoms in up to 80% of children who are allergic to it. If you have asthma and you’re consuming cow’s milk on a regular basis, there’s a good chance that it’s contributing to your symptoms.

There are a few different ways that cow’s milk can trigger asthma symptoms. First, it contains a protein called casein which can be inflammatory for some people. Additionally, cow’s milk also contains hormones and other compounds that can trigger an allergic reaction.

If you think that cow’s milk is triggering your asthma symptoms, the best thing to do is to eliminate it from your diet and see if your symptoms improve. There are plenty of other dairy-free options, so you don’t have to miss out on all the deliciousness that dairy offers.


If you thought that peanuts were just a tasty snack, think again! Peanuts can actually trigger asthma in some people. While most people with asthma are aware of their triggers and take steps to avoid them, peanuts can be a hidden danger.

Peanuts contain a protein that is similar to the protein that can cause an inflammatory response in the airways, leading to asthma symptoms. Peanuts are also one of the most common food allergies, so they can trigger a severe reaction in people who are allergic.

Processed Foods

Processed food can contain a lot of preservatives and other chemicals that can act as triggers for asthma. Some of these chemicals, such as bleach or formaldehyde, can be found in the packaging. Others, such as sulfites or MSG, may be added to the food itself. These additives can cause inflammation in the airways, making it difficult to breathe. If you have asthma, it’s important to avoid processed foods as much as possible. Stick to fresh fruits, vegetables, and whole grains instead. Your lungs will thank you!

Final Note

So there you have it, the top ten foods that can trigger asthma. If you or someone you know suffers from asthma, hopefully, this list will help you avoid some of the triggers. Just remember, everyone is different. So, what may trigger one person’s asthma may not affect another. If you are unsure about food, always check with your doctor before eating it.
