Asthma is a chronic lung disease that affects millions of people worldwide. It is commonly characterized by inflammation of the airways that results in breathlessness, coughing, and wheezing.

Although asthma can be controlled, sometimes it can be triggered by certain foods. This article explores the kinds of foods that can trigger asthma.

Foods High in Sulfites

Sulfite is a chemical that is present in some foods, particularly those with a long shelf life. These include dried fruits, pickled vegetables, wine, and beer.

Sulfites can cause asthma-like symptoms in some people, especially those who have a sensitivity to sulfites. Symptoms can include wheezing, coughing, and difficulty breathing. If you think you may have a sulfite sensitivity, it is best to avoid foods that contain sulfites.

Foods High in Histamine

Histamine is a chemical that is released by the body’s immune system during an allergic reaction. It is also found in some foods, such as fermented foods (e.g. sauerkraut), aged cheese, and cured meats.

Histamine can cause inflammation and narrowing of the airways, leading to asthma symptoms. If you are sensitive to histamine, it is best to limit your intake of these foods and talk to your doctor about any concerns you may have.

Foods Rich in Omega-6 Fatty Acids

Omega-6 fatty acids are found in many foods, including meat, poultry, eggs, and vegetable oils such as corn and soybean oil. While omega-6 fatty acids are essential to our diet, they can also contribute to inflammation and exacerbate asthma symptoms.

To reduce your risk of asthma flare-ups, it is recommended to limit your intake of omega-6 fatty acids and increase your consumption of foods rich in omega-3 fatty acids such as salmon and other fatty fish.

Caffeine and Chocolate

While caffeine and chocolate are not necessarily asthma triggers in everyone, for some people, they can cause symptoms such as chest tightness, shortness of breath, and wheezing.

This is because caffeine is a natural bronchodilator, which means it opens up the airways. However, it can also be a stimulant, which can trigger asthma symptoms in some people. Similarly, chocolate contains theobromine, which can also cause bronchoconstriction and worsen asthma symptoms in some individuals.

Milk and Dairy Products

Milk and dairy products can also cause asthma symptoms in some individuals, especially children. This is because dairy products contain casein, which is a protein that can cause mucus production and inflammation in the airways.

In addition, dairy products can also produce histamine in some individuals, which can cause asthma-like symptoms. If you think that milk and dairy products are triggering your asthma, consider removing them from your diet or talking to your healthcare provider about an allergy test.

Foods Containing Soy

Soy is a common ingredient in many foods, including processed foods, sauces, and baked goods. Some individuals may have a soy allergy, which can trigger asthma symptoms.

In addition, soy products can contain high levels of phytoestrogens, which have been linked to inflammation in the airways and asthma symptoms. If you have a soy allergy or sensitivity, it is best to avoid soy-containing products.

Food Additives

Food additives such as monosodium glutamate (MSG), artificial sweeteners, and food colorings have been linked to asthma symptoms in some people.

MSG is commonly found in Chinese food, while artificial sweeteners are often used in diet and low-calorie foods. Food colorings are often found in candy, soda, and other processed foods. If you think that food additives are triggering your asthma symptoms, try to avoid these products or talk to your doctor about any concerns you may have.

Conclusion

Asthma triggers can vary from person to person, but certain foods have been identified as common triggers. If you have asthma, consider keeping a food diary to identify any foods that may be triggering your symptoms.

In addition, talk to your healthcare provider to develop an asthma management plan that can help you control your symptoms. By avoiding triggers and following your asthma management plan, it is possible to live a full and active life with asthma.
