Food allergy & Food Intolerance Can Cause Asthma?

Some people have allergies to certain foods or intolerances to food additives. When an offending food is eaten,the immune system kicks into action, releasing immunoglobulin E to attack and interact with the allergen in the food. The mass cells then release histamine and other mediator,which cause allergic and asthmatic symptoms. Typical food allergens for children include eggs,milk,wheat,corn,peanut,soy,shellfish,citrus juices, artificial coloring and some flavorings.Adults tend to be allergic to peanut, tree nuts, eggs, yeast products, shellfish and fish.

Food intolerances are nonallergic food reactions. Something in the food cause the mast cells to release mediators,but the process is not a result of an interaction between IgE antibodies and allergens.However,the resulting symptoms are the same. Several studies have shown that high salt intake can make asthma symptoms worse,because it boosts substances that contribute to inflammation.Alcoholic beverages also can worsen asthma.

The most common food intolerance is sulfites, chemical preservatives used on fruits and vegetables. Sulfites can cause sever and even fatal asthma episodes.
