Problems relating to asthma can cause serious damage to your lungs. A way to avoid this is to prevent attacks based on triggers, such as air quality and environmental issues. If you have asthma, you may consider wearing a mask to help protect you from some of the common triggers, including pollen, mold, pet dander, pollution and, to some degree, strong odors. You can also use air filtration systems to remove and prevent many asthma triggers from entering your home. People with asthma may have certain food triggers that are typically unique to each person. In general, individuals with asthma should avoid the common triggers such as eggs, fish, peanuts, soy, yeast, cheese, wheat and rice. Foods with a variety of preservatives, such as Monosodium glutamate (MSG), nitrates or nitrites, also can be triggers for asthma. These substances also decrease the efficacy of rescue inhalers. These common allergies are the basis for the suggestion of an organic, whole food diet for asthma sufferers.
Avoid your asthma triggers. Cut out foods that aggravate your asthma.
