Allergists Debunk 11 Food Allergy Myths | Debunked

Food allergies can range in terms of severity, but there are several common symptoms that you should pay attention to. Before we get into some unique food allergies, you should be aware of the signs that you may have them by knowing the symptoms that are commonly associated with these allergies. The following symptoms could indicate that you may have a food allergy:

  • Swelling in the lips or face
  • Diarrhea
  • Itchy throat

Can Food Intolerances Be Prevented

Taking a few simple steps can help you prevent the symptoms associated with a food intolerance.

  • Learn which foods in which amounts cause you to have symptoms, and limit your intake to amounts you can handle.
  • When you dine out, ask your server about how your meal will be prepared. Some meals may contain foods you cannot tolerate, and that may not be evident from the description on the menu.
  • Learn to read food labels and check the ingredients for problem foods. Dont forget to check condiments and seasonings. They may contain MSG or another additive that can lead to symptoms.

How Is Food Allergy Testing Performed

Food allergy testing may involve the following:

  • Skin prick test: Your allergist first cleans your forearm. Next, they lightly prick your skin with a small device. They place a small drop of liquid food extract on your forearm skin. Within 15-20 minutes, you may observe a raised bump with redness around it. The allergist marks each test site with a pen to identify the allergen being tested.
  • Allergy blood test: Your allergist withdraws blood from a vein in your arm to check for Immunoglobulin E antibodies produced in response to an allergy-causing substance.
  • Oral challenge test: Your allergist gives you a small amount of the food suspected of causing the allergy. Next, they closely monitor you for any allergic reaction. An oral challenge test confirms food allergy after skin prick and allergy blood tests. Sometimes, people test positive during a skin prick test or blood test but have no symptoms during the oral challenge test.

How Can You Tell The Difference Between An Allergy And Intolerance To Food

Food allergies can be triggered by even a small amount of the food and occur every time the food is consumed. People with food allergies are generally advised to avoid the offending foods completely. On the other hand, food intolerances often are dose related people with food intolerance may not have symptoms unless they eat a large portion of the food or eat the food frequently. For example, a person with lactose intolerance may be able to drink milk in coffee or a single glass of milk, but becomes sick if he or she drinks several glasses of milk. Food allergies and intolerances also are different from food poisoning, which generally results from spoiled or tainted food and affects more than one person eating the food. Your health care provider can help determine if you have an allergy or intolerance, and establish a plan to help control symptoms.

What To Do If Symptoms Of An Allergic Reaction Occur

Symptoms of food allergies typically appear from within a few minutes to a few hours after a person has eaten the food to which he or she is allergic. A severe, life-threatening allergic reaction is called anaphylaxis.

Symptoms of allergic reactions can include:

  • Hives
  • Tingling or itchy sensation in the mouth
  • Face, tongue, or lip swelling
  • Vomiting and/or diarrhea
  • Swelling of the throat and vocal cords
  • Difficulty breathing
  • Loss of consciousness

People with a known food allergy who begin experiencing any of these symptoms should stop eating the food immediately, evaluate the need to use emergency medication and seek medical attention. Some of these symptoms are not always due to a food allergen. So, it is important to seek proper care and diagnosis from a healthcare provider to determine if the symptoms or reaction experienced was due to a food allergen.

How Are Food Allergies Treated

There’s no cure for food allergies, and the only real way to treat them is to avoid the food in question. But doctors can prescribe medicines to help lessen symptoms if they do happen, and even save a person’s life if the reaction is serious.

Antihistamines can treat isolated symptoms such as hives, runny nose, or abdominal pain associated with an allergic reaction.

If your doctor diagnoses you with severe allergies, he or she may prescribe epinephrine, which can be lifesaving if a person has anaphylaxis. Because it’s important that the medicine get into a person’s bloodstream quickly, epinephrine comes in an auto-injector.

If your doctor has prescribed epinephrine, you’ll need to take the auto-injector with you everywhere you go and also keep one on hand at home, school, and any relatives’ or friends’ homes that you visit a lot.

So how do you know when you should use epinephrine? Your doctor will go over this with you, but signs and symptoms of anaphylaxis include:

  • hoarseness
  • swelling in the mouth
  • trouble breathing
  • any symptoms from two or more body systems , such as hives and belly pain
  • any other combination of two or more symptoms that affect different parts of the body

Types Of Adverse Reactions To Foods

  • Food allergy due to IgE mediated mechanism

  • Food allergy not involving IgE, in which other immunological mechanisms are implicated

  • Non-allergic food intolerance

  • Food aversion

A true food allergy is a disorder in which ingestion of a small amount of food elicits an abnormal immunologically mediated clinical response. Food may cause allergic reactions by several mechanisms. The classic type I, IgE mediated reaction is the most thoroughly studied and potentially important in view of the risk of life threatening reactions in some people. Evidence is increasing, however, for an important role for delayed reactions . For example, eczema in children may be exacerbated by milk ingestion, and a small proportion of adults with severe contact dermatitis due to nickel may react to nickel in their diet.

    Food Labels And Allergens

    People with food allergies should read labels and avoid the foods they are allergic to. The law requires that food labels identify the food source of all major food allergens used to make the food. This requirement is met if the common or usual name of an ingredient already identifies that allergen’s food source name . Otherwise, the allergen’s food source must be declared at least once on the food label in one of two ways.

    The name of the food source of a major food allergen must appear:

    In parentheses following the name of the ingredient.Examples: lecithin , flour , and whey


    Immediately after or next to the list of ingredients in a contains statement.Example: Contains wheat, milk, and soy.

    FALCPA’s labeling requirements extend to retail and food-service establishments that package, label, and offer products for human consumption. However, FALCPA’s labeling requirements do not apply to foods that are placed in a wrapper or container following a customers order at the point of purchase.

    Consumers may also see advisory statements such as may contain or produced in a facility that also uses . These are used to address cross-contact, which can occur when multiple foods with different allergen profiles are produced in the same facility using shared equipment or on the same production line, as the result of ineffective cleaning, or from the generation of dust or aerosols containing an allergen.

    Treatment Of Food Allergies

    Treatment of food allergies became highly demanded nowadays due to the popularity of allergies in general and food allergies in particular. The primary way to deal with a food allergy is to avoid eating foods that are causing problems. Double-check the ingredient labels of your food products and find out if what to avoid is known by other names.

    The Food Allergy Labeling and Consumer Protection Act of 2004 requires US packaged food manufacturers to use plain, plain language to identify the presence of any of the eight most common food allergens milk, eggs, wheat, soybeans, peanuts, and nuts, fish and shellfish in their products. The presence of the allergen must be ascertained even if it is only a minor ingredient, e.g. an additive or a flavoring.

    Certain goods may also carry precautionary statements such as may contain, may contain, made on shared equipment, co-produced or any other indication of potential allergen contamination. There are no laws or regulations requiring these advisory warnings or standards to define their meaning.

    What Causes Food Allergies

    Food allergies happen when the immune system the body’s defence against infection mistakenly treats proteins found in food as a threat.

    As a result, a number of chemicals are released. It’s these chemicals that cause the symptoms of an allergic reaction.

    Almost any food can cause an allergic reaction, but there are certain foods that are responsible for most food allergies.

    Foods that most commonly cause an allergic reaction are:

    • milk
    • shellfish
    • some fruit and vegetables

    Most children that have a food allergy will have experienced eczema during infancy. The worse the child’s eczema and the earlier it started, the more likely they are to have a food allergy.

    It’s still unknown why people develop allergies to food, although they often have other allergic conditions, such as asthma, hay fever and eczema.
