While there is no specific asthma diet, certain foods may help or harm your breathing. A well-balanced diet with a variety of vitamins and nutrients can help keep your body healthy and reduce asthma symptoms. Eating fresh, nutritious foods and avoiding triggering foods may improve your overall health and asthma symptoms. In some cases, food allergies can also trigger asthma symptoms.

What You'll Learn
A balanced diet may reduce asthma symptoms
While there is no single food or nutrient that relieves asthma symptoms, a balanced diet may help reduce asthma flare-ups. A balanced diet, coupled with a healthy lifestyle, can improve overall health and asthma symptoms.
A balanced diet filled with fresh, nutritious foods can improve asthma symptoms. Fruits and vegetables are a good place to start. They are rich in vitamins C, E, and A/beta carotene, which have antioxidant and anti-allergic effects that support lung function. Vitamin E, in particular, has tocopherol, a chemical that could help cut down coughing and wheezing due to asthma. Selenium and magnesium are minerals that may help reduce asthma symptoms as they are powerful antioxidants that reduce oxidative stress in the lungs.
Some foods that should be avoided are sulfites, which are found in wine, dried fruits, pickled foods, and shrimp; foods that cause gas, such as beans, carbonated drinks, and fried foods; and common allergens like milk, shellfish, and wheat. These foods may trigger asthma symptoms. It is important to note that food allergies can also mimic or result in asthma symptoms.
Additionally, a balanced diet that includes fatty fish like salmon, herring, tuna, and swordfish can be beneficial due to their omega-3 fatty acids and vitamin D content. Vitamin D can strengthen the immune system's response and reduce swelling in the airways, thereby preventing asthma exacerbations.
While dietary changes can help manage asthma symptoms, it is important to consult a doctor before making any significant changes to your diet or stopping prescribed asthma medications.

Certain foods can trigger asthma
While there is no specific asthma diet, certain foods can trigger asthma symptoms. Food allergies can cause asthma symptoms, and asthma can also affect how you react if you have food allergies. Food allergies can be particularly dangerous for people with asthma, and asthma can make allergic reactions worse. In some cases, food allergies can also mimic asthma symptoms, making it difficult to distinguish between the two.
Food intolerances, which are different from food allergies, can also trigger asthma symptoms. The most common food intolerances are lactose, gluten, food additives, and food chemicals. While there is limited research on the link between food intolerances and asthma, some of the chemicals and ingredients in food may trigger asthma symptoms.
Some common foods that may trigger asthma symptoms include sulfites, which are preservatives found in wine, dried fruits, pickled foods, and other processed foods. Salicylates, which are naturally occurring chemical compounds found in coffee, tea, herbs, spices, and anti-inflammatory pills, may also trigger asthma symptoms. Eating large meals or gassy foods can put pressure on the diaphragm and trigger asthma flares.
On the other hand, eating a balanced diet with fresh, nutritious foods can help improve overall health and reduce asthma flare-ups. Fruits and vegetables rich in vitamins C, E, and A/beta carotene may have antioxidant and anti-allergic effects that support lung function. Selenium, found in fatty fish like salmon, is another powerful antioxidant that can help reduce oxidative stress and improve asthma symptoms.

Selenium and magnesium may reduce asthma symptoms
While there is no specific asthma diet, certain foods may help or harm your breathing. Although there is no single food or nutrient that relieves asthma symptoms, eating a balanced diet and avoiding triggering foods may help reduce asthma flare-ups.
Selenium is a trace mineral, and a selenium deficiency may play a role in the development of asthma. Selenium is a powerful antioxidant, and oxidative stress is a significant contributor to asthma. Selenium supplementation may help reduce symptoms of chronic asthma, as it can help reduce oxidative stress in the lungs. A 2022 study involving 206 patients found that selenium deficiency led to impaired immune response. Another study reported significant clinical improvement in the selenium-supplemented group, as compared to the placebo group.
Magnesium is also a powerful antioxidant, and a 2022 review of research on its anti-inflammatory properties found that it had a positive effect on lung function and reduced asthma symptoms.
Some foods that are rich in selenium include brazil nuts, fish, meat, and eggs. Magnesium-rich foods include leafy greens, legumes, nuts and seeds, and whole grains.

Vitamin E may decrease coughing and wheezing
While there is no specific asthma diet, certain foods may help or harm your breathing. For instance, eating fresh, nutritious foods and avoiding triggering foods may help reduce asthma flare-ups.
Vitamin E, an antioxidant, may be one such nutrient that helps with asthma. Vitamin E has been shown to have anti-inflammatory properties and can help stop "free radicals" that damage cells and could inflame and irritate your lungs.
In a study published in The Journal of Allergy and Clinical Immunology, researchers found that vitamin E supplementation decreased airway inflammation and allergic airway disease. The isoform α-tocopherol, specifically, has been shown to have anti-inflammatory properties and blocked airway hyperresponsiveness. However, it is important to note that the γ-tocopherol isoform has been shown to have pro-inflammatory effects and increased airway hyperresponsiveness.
In another study, participants with mild asthma received vitamin E (alpha-tocopherol) or a placebo for 14 days, and their inflammatory markers were assessed afterward. The study found that the two-week supplementation was associated with a reduction in airway inflammatory markers, with fewer eosinophils and mucus production than in patients receiving the placebo.
Vitamin E may, therefore, help decrease coughing and wheezing associated with asthma by reducing inflammation and mucus production. However, it is important to note that the studies on vitamin E and asthma have had conflicting outcomes, and more research is needed. Additionally, vitamin E supplementation has been shown to have detrimental effects in some people, so it is important to consult with a doctor before starting any new supplement.

Losing weight may help lessen asthma symptoms
Research has shown that losing weight can improve overall health and respiratory function in people with asthma. In a randomized clinical trial, 83% of asthma patients reported a better quality of life, and 58% showed improved asthma control after losing between 5% and 10% of their body weight. Even a small amount of weight loss can reduce the likelihood of asthma attacks, improve everyday activities, and decrease the need for emergency steroid treatments.
To lose weight, people with asthma should aim for a calorie deficit by reducing portion sizes or choosing nutrient-dense, low-calorie foods. Plant-based foods, such as fruits, vegetables, and whole grains, are excellent for maximizing nutrition while reducing calories. Healthy fats, such as omega-3 fatty acids from walnuts, avocado, olives, and fatty fish like salmon, are also recommended for better asthma control. However, it is important to consume fatty foods in moderation when trying to lose weight as they are high in calories.
In addition to dietary changes, physical activity can boost metabolism, burn calories, and improve respiratory health. When exercising, it is important to be mindful of asthma triggers and start slowly to prevent exercise-induced asthma attacks. This may include exercising indoors to avoid cold air or pollen triggers. Certain medications, such as GLP-1 receptor agonists, can also aid in weight loss and improve asthma symptoms, especially in individuals with diabetes or obesity.
Overall, losing weight can have significant benefits for individuals with asthma, improving their quality of life and helping to manage their symptoms more effectively. A healthy diet and regular exercise can contribute to weight loss and better respiratory health, ultimately leading to less severe asthma.
