Most food-allergic reactions are mild, but some are potentially life-threatening and require emergency treatment.<\/p><h3>What causes food allergies?<\/h3><p>A person with a food allergy has an immune system that overreacts to proteins found in certain foods. It is identified as a dangerous invader and the body creates a specific IgE (Immunoglobulin E) antibody to fight it. This triggers a protective response that can include skin, respiratory, heart and\/or digestive symptoms.<\/p><h3>How many people have food allergies?<\/h3><p>Approximately 32 million Americans have food allergies \u2013 26 million adults and nearly 6 million children, according to 2019 data funded in part by the National Institute of Allergy and Infectious Disease (NIAID).<\/p><h3>Find a practitioner who prescribes Palforzia<\/h3><h3>What are common food allergies?<\/h3><p>Nine foods account for 90 percent of all reactions in the United States. These nine foods are known as the \u201ctop 9\u201d food allergies:<\/p><ul><li>cow\u2019s milk<\/li><li>eggs<\/li><li>peanuts<\/li><li>tree nuts<\/li><li>wheat<\/li><li>soy<\/li><li>fish<\/li><li>shellfish<\/li><li>sesame<\/li><\/ul><p>Less common food allergens include corn, garlic, gelatin, lupin, meat, mustard, poppy seeds and sunflower seeds. In infants and children, the most common food allergy is peanut, milk, shellfish, tree nuts, eggs and fish. The most common food allergy in adults is shellfish (shrimp, crayfish, lobster), followed by cow\u2019s milk, peanuts, tree nuts and fish (such as salmon).<\/p><h3>What are the symptoms of food allergies?<\/h3><p>Symptoms of food allergies can vary from person to person and from reaction to reaction. Reactions can be different with each episode, even for the same person \u2013 that\u2019s part of the difficulty of managing food allergies. Symptoms can range from mild to severe. Symptoms usually appear within minutes of eating the food, though they can sometimes occur hours later.<\/p><p>Each of the symptoms can occur alone or in combination with other symptoms. In a severe reaction, sometimes you\u2019ll see a combination of symptoms from different body areas.<\/p><p>Symptoms of a mild allergic reaction are:<\/p><ul><li>Itchy or runny nose, sneezing<\/li><li>Itchy or tingling sensation in the mouth<\/li><li>A few hives, mild itching of skin<\/li><li>Mild nausea or discomfort<\/li><\/ul><p>Symptoms of a severe allergic reaction, also known as <a href=\"https:\/\/allergyasthmanetwork.org\/anaphylaxis\"><strong>anaphylaxis:<\/strong><\/a><\/p><ul><li>Short of breath, wheezing, repetitive cough<\/li><li>Appears pale, blue, faint, dizzy, confused<\/li><li>Tightness in throat, hoarse, trouble breathing or swallowing<\/li><li>Stomach discomfort such as abdominal cramps; diarrhea, or vomiting<\/li><li>Swelling of tongue or lips<\/li><li>Hives over a large area of the body<\/li><li>Feeling of impending doom<\/li><\/ul><h3>How is a food allergy diagnosed?<\/h3><p>Studies show that more than half of presumed food allergies are not actually allergies. That is why an accurate diagnosis is essential.<\/p><p>Board-certified allergists have special training and experience in putting together to make a diagnosis of food allergy based on:<\/p><ul><li>your history of symptoms<\/li><li>physical exams<\/li><li>allergy testing<\/li><\/ul><h3>How can I use a food diary to track food allergy symptoms?<\/h3><p>The first thing a doctor looks at when diagnosing food allergy is your history of symptoms. If you think you might have a food allergy, keep a written diary with the following information:<\/p><ul><li>What symptoms did you notice?<\/li><li>How long after eating did you notice symptoms?<\/li><li>How long did the symptoms last and how severe were they?<\/li><li>Did you do anything to help ease the symptoms (such as take prescription or over-the- counter medications)?<\/li><li>What exactly did you eat and how much?<\/li><li>Where and how was the food processed? Was it at home? A restaurant?<\/li><li>How was the food prepared: raw? boiled? roasted?<\/li><li>Were you doing anything else during or just after your meal, like exercising?<\/li><\/ul><p>Show your diary to your doctor. Sometimes the food allergy is obvious, but follow-up testing is important to confirm the diagnosis.<\/p><h3>What kinds of tests are done for food allergies?<\/h3><p>The food allergy tests performed most often by allergists are:<\/p><ul><li>skin prick test<\/li><li>blood test<\/li><li>oral food challenge<\/li><\/ul><h3>Skin prick tests<\/h3><p>A diluted extract of the food is placed on your skin, then the skin is scratched with a needle. If you develop a raised skin reaction (called a wheal) at the place of the needle prick, that indicates possible allergy. If there is no reaction, you are unlikely to be allergic to the food.<\/p><p>Skin prick tests are quite accurate for foods with stable proteins, including peanut, milk, egg, tree nuts, fish and shellfish \u2013 some of the most common food allergens in the United States. They are less reliable for fruits and vegetables, which have proteins that break down quickly.<\/p><h3>Blood tests<\/h3><p>Blood tests that look for IgE antibodies are useful for identifying food allergies. They are particularly helpful for people whose allergy history puts them at high risk of serious reaction to a skin prick test; whose skin problems make skin-prick uncomfortable or dangerous; or who take certain medications that interfere with skin prick test results.<\/p><h3>Oral food challenge<\/h3><p>Your doctor may recommend an oral food challenge test to diagnose a food allergy. The patient is asked to eat very slowly a tiny amount of a food, then gradually larger amounts, to determine if there\u2019s an allergic reaction.<\/p><p>Because an oral food challenge always carries risk, it should be performed by an allergist trained in how to conduct the test and at a medical facility that has <a href=\"https:\/\/allergyasthmanetwork.org\/anaphylaxis\/what-is-epinephrine\/\">epinephrine<\/a>, oxygen, IV fluids and other treatments for potentially severe reactions.<\/p><h3>Food challenges are safe when done properly \u2013 only about 2% of people experience anaphylaxis from testing.<\/h3><h3>Testing with large panels of food allergens is not recommended<\/h3><p>Allergy experts do not recommend using food allergy panel blood testing. Panels test many different foods all at one time. Panels are not recommended because allergy blood tests are not entirely accurate.<\/p><p>Blood tests may have what is known as false positive results, where a test for a food allergy is positive but the person is not truly allergic. This is why allergy testing alone cannot be used to diagnose a food allergy.<\/p><p>Patients who test \u201cpositive\u201d to numerous foods might choose to eat very restrictive diets, which can be unhealthy and difficult to follow. That\u2019s why seeing an allergist trained to put all the evidence together for a diagnosis is important.<\/p><h3>How do I treat a food allergy reaction?<\/h3><p>If you typically experience mild reactions to food, follow your doctor\u2019s instructions for treatment. Mild symptoms can quickly become severe, however. A severe reaction is called anaphylaxis. Skin symptoms like hives are not always present with anaphylaxis.<\/p><p>Epinephrine is the first line of treatment used to treat anaphylaxis. It comes in the form of an injection or auto-injector. Patients at risk for anaphylaxis are advised to always carry epinephrine auto- injectors with them at all times.<\/p><p>In a severe reaction, do not delay treatment \u2013 treat with epinephrine IMMEDIATELY. Epinephrine is the only treatment that will resolve anaphylaxis. Antihistamines like Benadryl\u00ae will not reverse anaphylaxis.<\/p><p>\u00a0<\/p><p><strong>Information from<\/strong>: Allergy &amp; Asthma Network website,\u00a0<a href=\"https:\/\/allergyasthmanetwork.org\/allergies\/food-allergies\/\">https:\/\/allergyasthmanetwork.org\/allergies\/food-allergies\/<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>A food allergy is an immune system response that occurs soon after a person eats a certain food.
