Nutritional Insights on Food Allergies and Asthma


When we thing of spring we usually think of green grass, short days and warm sunshine. But we also associate spring with flying pollen, asthma fl are ups and constant allergic reactions. While most people do not think these things can be prevented, there are ways that they can be managed. This article discusses food allergies and asthma; even though food allergies and asthma are not a seasonal allergy it is still very important to educate members on how to manage their conditions.


Food Allergies


A food allergy occurs when the immune system mistakenly attacks a food protein. Ingestion of the off ending food may trigger the sudden release of chemicals, including histamine, resulting in symptoms of an allergic reaction. The symptoms
may be mild (rashes, hives, itching, swelling, etc.) or severe (trouble breathing,
wheezing, loss of consciousness, etc.).   A food allergy can be potentially fatal and
scientists estimate that approximately 12 million Americans suffer from food allergies. There is no cure for food allergies and research studies are inconclusive about whether food allergies can be prevented.  A strict avoidance of the allergy-causing food is the only way to avoid a severe reaction. Reading ingredient labels for all foods is the key to steer clear of a reaction.  If the product doesn’t have a food label, those with a food allergy should not eat that food. If in doubt about the safety of a certain food, call the manufacturer for more information and check our website listing information later in this article. 


Common Food Allergens


There are eight foods that account for 90% of all food-allergic reactions. They are milk, eggs, peanuts, tree nuts, fish, shellfish, wheat, and soy.




There are a few foods that trigger asthma problems.   Sulfites and sulfiting agents in foods (found in dried fruits, prepared potatoes, wine, bottled lemon or lime juice, and shrimp), and diagnosed food allergens (such as milk, eggs, peanuts ,tree nuts, soy, wheat, fish, and shellfish) have been found to trigger asthma symptoms.  The incidence of asthma has risen in the United States during the past three decades, and many researchers believe that the changes in our diets have something to do with it. Several research studies have suggested that as Americans continue to eat fewer fruits and vegetables and more processed foods, we are possibly running the risk developing asthma.  While the connection between diet and asthma remains inconclusive for now, there is evidence that people who eat diets higher in vitamins C and E, beta-carotene, flavonoids, magnesium, selenium, and omega-3 fatty acids have lower rates of asthma. Many of these items contain antioxidants, which protect cells from damage. 


The Role of Antioxidants


So what kinds of foods have antioxidants which can help asthma? Eating plenty and variety of fruits and vegetables is a great start. Also, foods that are high in omega-3 fatty acids (i.e fish such as salmon, tuna, and sardines as well as some plant sources like flaxseed), are believed to have a number of health benefits. Although evidence of the
specific benefits as it relates to asthma is not clear, it’s still a good idea to include them in your diet. Avoid trans fats and omega-6 fatty acids foods as there is some evidence that eating them in foods like margarine and processed foods, may worsen asthma.
