What Are The Signs Of An Allergic Reaction To Peanut Butter

The Truth About Peanut Allergies

The signs of an allergic reaction to peanut butter typically include skin reactions, like hives or eczema. Some people may have stomach and digestive trouble, or experience other common allergy symptoms, such as coughing and sneezing. In some cases, the reaction can be severe and may include facial swelling and trouble breathing.

A rash or other reaction on the skin is a very common allergic reaction to peanut butter and other foods. Usually, a skin reaction is considered a mild reaction. A person may break out into hives or raised red rashes on the skin or experience mild swelling in the face. There may also be a feeling of itchiness or tingling when an allergic person is exposed to peanuts or peanut butter. Eczema, an inflammation of the skin that’s often characterized by red, flaky patches, is another common reaction to certain foods.

Some people experience digestive problems when they eat peanut butter. They may have diarrhea or vomiting, along with stomach pains and cramps. The reaction usually passes once the peanut butter is out of the person’s system.

Testing For Nut Allergies

After your allergist takes a detailed history of your childs allergic experiences, including prior exposures and possible reactions, your allergist will likely run some tests to further understand your childs allergies, says Dr. Leeds. This will include blood tests and skin prick tests. “, it is incredibly important that a detailed history precedes any testing because allergy tests can often have false positives.

Dr. Swanson explains that blood tests measure your childs immune response to foods that you suspect they may be allergic to, and check the amount of immunoglobulin E antibodies in their blood.

A skin test is administered by exposing your child’s skin to a small amount of the allergen, pricking their skin with a needle, and then looking for reactions, such as raised bumps. Other possibilities include oral food challenges, where small, safe amounts of the allergen are fed to your child in the allergists office and your child is monitored for reactions.

What Causes Peanut Allergy

Theres a lot of confusion and speculation about what causes food allergies. A recent post here on tackled this issue, in fact, as part of an overall look at why theres been a rise in food allergies. A recent report released by the National Academies of Science called Finding a Path to Safety in Food Allergy Assessment of the Global Burden, Causes, Prevention, Management, and Public Policy challenges what we think we know about food allergies. With regard to why food allergies develop, report authors say that the contributing factors contributing are poorly understood. The report lists the most common hypotheses for why individuals develop food allergies are as follows: microbial hypothesis allergen avoidance hypothesis dual allergen exposure hypothesis nutritional immunomodulation hypothesis and other hypotheses.

Heres a very brief introduction to each hypothesis:

  • Microbial hypothesis Incorporates the hygiene hypothesis and the old friends hypothesis, which suggest that a host of environmental factors impact our microbiome and those microbes interact with our immune system in positive ways. Changes in the microbiome may contribute to the development of food allergies.
  • Allergen avoidance hypothesis Suggests that the avoidance of potential allergens in the prenatal and early infant periods could prevent allergies. Because the evidence does not support avoidance as a means to prevent food allergy, this is no longer recommended.

    What Is Nut Allergy

    An allergy occurs when your body’s immune system, which normally fights infection, overreacts to a substance called an allergen. Most allergens are not obviously harmful and they have no effect on people who are not allergic to them. Allergic reactions to allergens can vary from mild to life-threatening.

    Both peanuts and tree nuts can act as allergens, and can cause an allergic reaction in some people. When you come into contact with something that you are allergic to , a group of cells in your body, called mast cells, release a substance called histamine. Histamine causes the tiny blood vessels in the tissues of your body to leak fluid which causes the tissues to swell. This results in a number of different symptoms.

    Strictly speaking, peanuts are not nuts, they are legumes, in the same family as peas and beans. Peanuts grow underground whereas other nuts grow on trees. The word nut in this leaflet can mean either tree nuts or peanuts.

    See also the separate leaflets called Allergies and Food Allergy and Intolerance for more information about allergy in general.

    Who Gets Delayed Anaphylactic Reactions

    Information about Anaphylaxis for parents

    A 2015 study found that 2 percent of people treated for an allergic reaction at hospital emergency rooms developed a second, late reaction. That delayed reaction occurred, on average, 15 hours after people were first treated. Another study found that about 15 percent of children had a second severe allergic reaction hours after their first reaction.

    Youre more likely to have a delayed reaction if you:

    • have a severe peanut allergy
    • dont get treated with epinephrine quickly enough
    • dont get a large enough dose of epinephrine
    • dont respond quickly to epinephrine
    • have low blood pressure during your first reaction
    • have a history of delayed anaphylaxis

    How Is Anaphylaxis Treated

    Epinephrine is first-line treatment for anaphylaxis, and epinephrine auto-injectors contain a pre-measured dose of the medication. Antihistamines and asthma medications shouldnt be used instead of epinephrine for treating anaphylaxis, but can be given as secondary medications. After receiving epinephrine, a person should go to hospital, ideally by ambulance, for observation and/or further treatment. Learn more about emergency treatment.

    A Severe Reaction: Anaphylaxis

    This is a life-threatening allergic reaction and needs emergency treatment. Peanuts are one of the most common causes of anaphylaxis, which can affect several parts of the body all at once.

    Your risk may be higher if you have allergies or asthma, a family history of anaphylaxis or if its happened to you before. The FDA has recently approved the medication Palforzia for children aged 4 to 17 with peanut allergiies to help minimize any reaction. While they should still avoid contact with peanuts, it helps reduce the risk of them being life threatening.

    Certain people with known peanut allergies should carry an injector. You can get one from your doctor. If the symptoms strike, use your epinephrine injector, such as Auvi-Q, EpiPen, Symjepi or a generic version of the auto-injector..

    The signs of an attack can include:

    • Swelling of the throat that makes it hard to breathe
    • Dizziness or fainting
    • A big drop in blood pressure
    • A rapid pulse
    • Blocked airways

    How Is A Tree Nut Or Peanut Allergy Treated

    There is no special medicine for nut or peanut allergies and many people don’t outgrow them. The best treatment is to avoid the nut. That means not eating that nut, and also avoiding the nut when it’s mixed in foods.

    Staying safe means reading food labels and paying attention to what they say about how the food was produced. Some foods don’t contain nuts, but are made in factories that make other items that do contain nuts. The problem is the equipment can be used for both foods, causing “cross-contamination.” That’s the same thing that happens in your own house if someone spreads peanut butter on a sandwich and dips that same knife into the jar of jelly.

    After checking the ingredients list, look on the label for phrases like these:

    • “may contain tree nuts”
    • “produced on shared equipment with tree nuts or peanuts”

    People who are allergic to nuts also should avoid foods with these statements on the label. Some of the highest-risk foods for people with peanut or tree nut allergy include:

    • cookies and baked goods
    • Asian and African foods
    • sauces

    Talk to your allergist about how to stay safe in the school cafeteria. Also ask about how you should handle other peanut encounters, like at restaurants or stadiums where people are opening peanut shells. People with nut allergies usually won’t have a reaction if they breathe in small particles. That’s because the food usually has to be eaten to cause a reaction.

    The Risk Of Casual Contact

    In those who are especially sensitive, reactions to peanuts can occur from ingesting just a trace amount. This can cause anxiety, especially for the parents of peanut-allergic children. However, research shows that touching, smelling, inhaling airborne particles or just being near peanuts is highly unlikely to cause a severe reaction : 180-2.)

    Smelling the aroma of peanuts is not the same as inhaling airborne peanut particles that could potentially contain the allergenic protein. The aroma of peanuts comes from different compounds that cannot cause an allergic reaction. Also, highly refined peanut oil is not required to carry allergen labeling because the process used to purify the oil removes the protein, thereby making it no longer allergenic.

    In one controlled study, 30 children with significant peanut allergy were exposed to peanut butter, which was either pressed on the skin for one minute, or the aroma was inhaled. Reddening or flaring of the skin occurred in about one-third of the children, but none of the children in the study experienced a systemic reaction.

    How Can I Prevent A Peanut Allergy

    Feeding infants small amounts of peanut-containing foods can lessen the chances that they will develop an allergy. One study found that 17% of babies who did not eat peanuts developed an allergy by age 5. In contrast, only 3% of those who ate peanuts developed a peanut allergy by age 5.

    Always ask your childs healthcare provider for recommendations about feeding your child peanuts. The timing of introducing your child to peanuts varies, depending on if your child has:

    • Egg allergies.
    • Both severe food allergies and eczema.

    What Causes A Peanut Allergy And Allergic Reactions To Peanuts

    The science is not clear as to what causes peanut allergy. Both genetic and environmental factors appear to be involved. The groundbreaking LEAP Study found that the introduction of peanuts into an infants diet, prior to 11-months old, reduced the prevalence of peanut allergy significantly. As a result of the LEAP study, new guidelines have been released to encourage early introduction of peanut foods. Research has shown that introducing peanut foods early to those infants who are at high risk reduced rates of developing peanut allergies by up to 86%. Implementing early introduction will hopefully reduce the prevalence of peanut allergies for future generations.

    What Tests Help Diagnose A Peanut Allergy

    Allergic Reactions Described

    Your healthcare provider may use a blood test to diagnose a peanut allergy. A blood test called an immunocap radioallergosorbent checks the number of antibodies in your blood. A higher number of certain types of antibodies can indicate an allergy.

    Your healthcare provider may also use a skin test to identify or rule out multiple types of allergies. During a skin test, your provider:

    • Makes a few tiny needle pricks in your back or arm.
    • Applies small doses of different types of allergens where you have needle pricks.
    • Montiors your skin reaction and interprets them after 15 minutes.

    Skin patches that become red and itchy indicate an allergic response. Your provider can use this information to diagnose allergies.

    You may also have an oral food challenge. During an oral food challenge, you eat tiny, increasing amounts of a peanut-based product in your healthcare providers office. Your healthcare provider has emergency medication and equipment on hand in case you have an allergic reaction.

    Can Food Allergy Be Prevented

    In 2017, guidelines were released by the U.S. National Institute of Allergy and Infectious Diseases on prevention of peanut allergy. These guidelines recommended introducing peanut to high-risk infants around 4-6 months of age to help prevent the development of peanut allergy.

    In 2019, the Canadian Paediatric Society released on the specific timing of early introduction of allergenic foods for high-risk infants. The new guidance is to actively offer non-choking forms of foods containing common allergens around 6 months of age, but not before 4 months, as this can be effective in preventing food allergy in some high-risk infants.

    Why Do So Many People Seem To Have Food Allergy These Days

    There is no easy explanation to explain the prevalence of food allergy. One theory, known as the dual-allergen exposure hypothesis suggests that initial exposure to food allergens through the skin, especially in babies with eczema, can lead to allergy while oral exposure can lead to tolerance. Another theory, the hygiene hypothesis, suggests that people in Western countries are living in cleaner and more sanitized environments, and their immune systems are shifting toward developing allergic responses to certain foods and away from fighting germs or infections.

    The risk factors for food allergy include:

    • Age: Food allergy is more common in young children than in older children or adults.
    • Family history: Youre more likely to have a food allergy if your parent or sibling has one.
    • Another food allergy: If you have a food allergy, youre at greater risk for developing another.
    • Related medical conditions: Your risk is increased if you have an allergic disease such as asthma, eczema, or hay fever.

    If you think you are allergic to peanuts, see an allergist. Start a food diary before the appointment and keep track of any reactions.

    If youve never had a severe reaction, they might suggest whats called an elimination diet. You would cut out peanuts or other suspected foods for a week or longer. Then you would add them back in one at a time to see what might be causing you to react.

    Your doctor may also do a skin test, placing a small amount of the food on you and then pricking it with a needle. If you are allergic to peanuts, you will develop a raised bump or reaction.

    You may also need a blood test to check to see whether your immune system launches an allergic reaction to peanuts.

    How To Know If My Child Is Allergic To Peanut Butter

    Peanut butter is one of the most common culprits that cause serious allergic reaction in children. Even a small amount of peanut butter can trigger serious allergy symptoms in a toddler. Almost 20% of children suffer from peanut allergy, and their symptoms get better on their own as they age. Still, such an allergy can reoccur anytime later in their life. Kids with a family history of asthma, eczema, hay fever and food allergies are most prone to develop peanut butter allergy. Here at, we are going to discuss how to know if your child is allergic to peanut butter.

    Peanut Allergy: What You Should Know

    Peanuts were once a snack-time staple, but these days, they are largely off-limits for a growing number of kids and adults. Its common now not to serve certain foods at birthday parties or school to keep kids with peanut allergies safe.

    It can seem scary how much damage a little piece of food can do, but you can lower the risk of having a severe reaction if you learn how to spot your symptoms and avoid peanuts.

    What Happens With A Tree Nut Or Peanut Allergy

    Does Peanut Butter cause Acne?

    Your immune system normally fights infections. But when someone has a nut allergy, it overreacts to proteins in the nut. If the person eats something that contains the nut, the body thinks these proteins are harmful invaders and responds by working very hard to fight off the invader. This causes an allergic reaction.

    What Are Symptoms Of An Allergic Reaction What Should I Look For

    Mild symptoms can include:

    • A few hives around the mouth or face

    More severe symptoms can include any of the following alone or in combination:

    • Lip swelling
    • Change in skin color
    • Sudden tiredness/lethargy/seeming limp

    * If you have any concerns about your infant’s response to peanuts, seek immediate medical attention/911.

    Depending on their age, your child may not have the words to describe the reaction they are feeling. Listen for phrases like:

    • My tongue is hot or burning
    • My mouth itches or tingles
    • My mouth/throat feels funny
    • Something is stuck in my throat
    • It feels like there are bugs in my ears
    • My tongue feels bumpy

    Very young children may pull or scratch at their tongue or ears, show an increase in drooling or sound different.

    The most severe reaction is called anaphylaxis. Anaphylaxis is a medical emergency. If you do not have epinephrine on hand, call 911 to get immediate help.
