The Impact Of Peanut Allergy On Quality Of Life

Peanut-allergy prevention in infants – Dr. Maria Garcia-Lloret | UCLA Mattel Children’s Hospital

Peanut allergy can be frustrating and isolating for children. Many children with peanut allergies miss out on experiences outside of the home, because foods served at these experiences could possibly contain peanut.

Children with peanut allergies may also be excluded or bullied because of their allergy. As many as 1 in 3 children with food allergies has experienced bullying at least once.

As many as 1 in 3 children with food allergies has experienced bullying at least once.

Eating out can be difficult to manage, as many foods may have peanut as an ingredient. And peanut cross-contamination concerns can make things even more complicated. If you cant guarantee that a food preparer avoided cross-contamination, your child will need to skip the food .

Schools are starting to adopt peanut-free policies, making the school experience safer and more inclusive for children with peanut allergies. But not all schools have adopted this policy and more allergy awareness is needed in school so children with peanut allergies arent excluded or bullied.

Peanut Allergy: Early Exposure Is Key To Prevention

Posted on by Dr. Francis Collins

With peanut allergy on the rise in the United States, youve probably heard parents strategizing about ways to keep their kids from developing this potentially dangerous condition. But is it actually possible to prevent peanut allergy, and, if so, how do you go about doing it?

Theres an entirely new strategy emerging now! A group representing 26 professional organizations, advocacy groups, and federal agencies, including the National Institutes of Health , has just issued new clinical guidelines aimed at preventing peanut allergy . The guidelines suggest that parents should introduce most babies to peanut-containing foods around the time they begin eating other solid foods, typically 4 to 6 months of age. While early introduction is especially important for kids at particular risk for developing allergies, it is also recommended that high-risk infantsthose with a history of severe eczema and/or egg allergyundergo a blood or skin-prick test before being given foods containing peanuts. The test results can help to determine how, or even if, peanuts should be introduced in the youngsters diets.

  • Infants with mild to moderate eczema should incorporate peanut-containing foods into their diets by about 6 months of age. Its generally OK for them to have those first bites of peanut at home and without prior testing.



Change Your Child’s Future

Imagine not having to worry you child will develop an allergy to peanuts and the lifetime of anxiety and fear that come with it. Fortunately, pediatricians, allergists and others who care for babies now agree: feeding small amounts of peanut foods to infants at the right stage of their development typically around 4-6 months of age can have life-changing effects

How To Prevent Peanut Allergy In Infants

Peanut allergy is one of the most common food allergies in the United States. Between 1 and 2 percent of children and adolescents are allergic to peanuts and that number has doubled in Western nations over the past decade.


Peanut allergy, a severe and potentially fatal immune response to certain peanut proteins, develops early in life and is rarely outgrown. It is unknown why some children develop peanut allergies or why the prevalence has grown in recent years.

For many years, national guidelines recommended avoiding peanut consumption during pregnancy, lactation and infancy. However, new research has shown that early introduction of peanuts to infants at high risk for peanut allergy reduces the development of peanut allergy later on in life by approximately 80 percent. As a result, the National Institute of Allergy and Infectious Diseases recently released an updated guideline endorsing the addition of peanuts in babies diets, starting at 4 months of age.

However, this is not a blanket recommendation to give all babies peanuts, says , UCLA pediatric immunologist. The updated guidelines provide specific recommendations depending on the childs risk of developing peanut allergy.


Signs and symptoms

1. Infants with severe eczema and/or egg allergy: Schedule an in-office medical evaluation with an IgE test, a skin-prick test, or both with physician approval, introduce age-appropriate peanut-containing food as early as 4 to 6 months of age.

A Peanut Allergy Myth

How to Prevent Peanut Allergy in Infants

Contrary to urban legend, a childs peanut allergy cannot be triggered by a classmate eating a peanut sandwich across the table. The allergens are not airborne in this way.

Younger children do need to be monitored so they dont share foods accidentally. Wash eating areas and hands with soap and water after eating so a smudge of peanut butter doesnt accidentally get transferred to a child with an allergy.

However, it is not necessary to ban all peanut products from a school because one child is allergic. Peanut allergy is just one of many food allergens. Talk with your allergist about common safe practices for school. There are many resources available to help manage school safely for a child with food allergies.

Symptoms Of Peanut Allergy

Peanut allergy reactions can range from mild to severe, and can sometimes be life-threatening. The same person can experience different symptoms from reaction to reaction. And a reaction that starts out mild could become severe.

Some common symptoms of a peanut allergy reaction include:

  • Hives
  • Dizziness
  • Fainting

When a peanut allergy reaction involves severe symptoms in more than one organ system, this is known as anaphylaxis. Anaphylaxis can be life-threatening.

Swelling of the tongue, throat or face, difficulty breathing, wheezing, breathing, and significant cardiovascular symptoms may be signs of anaphylaxis. If your child shows any signs of anaphylaxis, immediately call 911 and give an epinephrine injection .

How Long After Eating Peanuts Will An Allergic Reaction Occur

It can take up to 2 hours for signs of a peanut allergy reaction to show up, but sometimes in more severe cases signs and symptoms will appear immediately within minutes.

For infants with a life-threatening peanut allergy the symptoms will usually come on very quickly after coming into contact with peanuts due to a sudden release of chemicals in the immune system .

Are Airborne Peanut Allergies Real

Peanut foods for infants may prevent allergies: panel

There has never been a documented case of a baby reacting to peanut simply by being near it. Nearly all households with kids have some “peanut dust” lying around, but no one has ever reported an allergy from that exposure.

Even in infants with severe peanut allergies, airborne reactions are exceedingly rare.

There have been documented cases of older children and adults reacting to peanuts simply by being around them, but infants are different. If you are an adult out in public and you are concerned with coming into contact with airborne peanut dust and or touching a surface the has peanut residue you should consider getting the Healthy Lifestyle kit from Seat Sitters. This Kit provides a protective layer between you and public seating. Or the Healthy Airplane Travel Kit from Seat Sitters if you are traveling.

Suggested Procedure For Introduction Of Peanut Before 12 Months When The Infant Is Developmentally Ready For Solid Food

  • Rub a small amount of smooth peanut butter/paste on the inside of the infant’s lip .
  • If there is no allergic reaction after a few minutes, feed the infant ¼ teaspoon of smooth peanut butter/paste and observe for 30 minutes.
  • If there is no allergic reaction, give ½ teaspoon of smooth peanut butter/paste and observe for a further 30 minutes.
  • If there is no allergic reaction, parents should continue to include peanut in their infants diet in gradually increasing amounts at least weekly, as it is important to continue to feed peanut to the infant as a part of a varied diet.
  • If there is an allergic reaction at any step, stop feeding peanut to the infant and seek medical advice .
  • An allergic reaction should be treated by following the ASCIA Action plan: www.allergy.org.au/hp/ascia-plans-action-and-treatment – Mild or moderate allergic reactions can be treated using non-sedating antihistamines such as cetirizine, loratadine or desloratidine. To avoid confusion with the symptoms of anaphylaxis, sedating antihistamines should not be used to treat allergic reactions.- If there are symptoms of anaphylaxis treat with adrenaline and call an ambulance immediately.
  • If an infant has an allergic reaction they may be referred to a clinical immunology/allergy specialist for further investigations: www.allergy.org.au/patients/locate-a-specialist

Peanut Exposure Vs Peanut Avoidance

Suspecting that early exposure might be a better approach, a group of U.K. researchers developed a large-scale study to compare the outcomes of early exposure versus the outcomes of avoidance. More than 600 children aged four to 11 months who were identified as being at risk for developing peanut allergy based on having severe eczema and/or an egg allergy were enrolled in the LEAP study. All of the children were skin tested and passed an oral challenge with peanut before being divided into two groups. One group of children was assigned to eat a peanut snack several times each week until they reached the age of five, while the other group was assigned to strictly avoid peanut consumption. The study found that regular peanut consumption, as compared to peanut avoidance, reduced the risk of developing peanut allergy by more than 80 percent.

For the LEAP-ON follow-up study, researchers followed the original consumption and avoidance groups after they were directed to forego peanuts for an entire year immediately after the end of the initial study. This resulted in only a nominal increase in peanut allergy development among both groups, demonstrating, says Dr. Hsu, that early exposure has some lasting effect.

New Guidelines For Preventing Peanut Allergy In Babies

Follow me on Twitter @drClaire

In 2015, a study showed that giving peanut products to babies could help prevent peanut allergy. This was exciting news, given that 1-2% of children suffer from peanut allergy, an allergy that can not only be life-threatening but last a lifetime, unlike other food allergies that often improve as children get older.

This is a change for pediatricians and parents, who traditionally have thought that peanut products shouldnt be given until children are a bit older. Its also tricky in that babies can choke on peanuts and peanut butter. And to make it even trickier, the study cautioned that some babies at higher risk of peanut allergy might need testing before trying out peanut products. So it is great news that the American Academy of Pediatrics has come out with a guideline that gives specific guidance to pediatricians on how to implement the findings of the study.

The guideline divides babies into three groups:

  • babies with severe eczema and/or egg allergy
  • babies with mild to moderate eczema
  • babies without eczema or food allergy.

The second group, those with mild to moderate eczema, dont need to get testing although parents should talk to their doctors about their particular situation and see if testing might be a good idea. Those babies should get peanut products at around 6 months of age, once they can handle solid foods.

How To Eat Out Safely When Your Child Has A Peanut Allergy

Having a child with severe allergies turns everyday meals into a much bigger deal. When you cook for your child at home, you can check that every ingredient you use is peanut-free. But eating out takes some of the control out of your hands.

Restaurant menus don’t always list every ingredient. And even dishes that don’t have nuts could get contaminated when they’re cooked using the same bowls and spoons as foods with nuts.

You don’t have to eat at home all the time, or bring your own food to restaurants. Dining out can be safe for your child if you choose your restaurants carefully, plan your visit, and talk to the staff.

How To Find Out If My Baby Has A Peanut Allergy

When introducing a new food, parents should watch their infant for signs of an allergic reaction. An allergic reaction could happen as soon as seconds and up to two hours after eating the new food.

If signs continue for more than 12 hours after contact with peanuts, contact your doctor.

Signs of a peanut allergy in babies can be warning of allergies to other foods as well. Unlike other food allergies, a peanut allergy can often lessen or disappear as kids get older. Although, in more severe cases a peanut allergy could be both life-threatening and lifelong.

The Lowdown On Peanut Allergies

A peanut allergy is the ultimate irony: Your childs immune system mistakenly thinks peanuts are dangerous. It then overreacts to the point where eating peanuts becomes, well, dangerous.

Peanutproteins are very allergenic, explains Dr. Bjelac. We also believe that thecooking method affects their allergenicity. Most peanut products consumed inthe U.S. are roasted, which increases how allergenic they are.

And unfortunately, peanut allergies are on the rise, tripling between 1997 and 2008. Dr. Bjelac estimates that peanut allergies now affect around 3% of U.S. children, or 1.2 million children and teens.

While most food allergy is found in childhood, peanut allergies tend to persist into adulthood. Less than 20% of kids will outgrow a peanut allergy, relates Dr. Bjelac. But if you empower yourself with the right information, you and your child can still have a great quality of life.

The Truth About Peanut Allergies In Kids

Its no surprise that peanuts are often feared by parents the number of kids with peanut allergies has tripled in the past 15 years.

But peanuts can be your babys food friend. Really!

New research shows that introducing small amounts of peanut products to your baby can help your child avoid being among the 1 in 50 kids with a peanut allergy.

In fact, giving a little peanut butter or mixing in peanut powder with other foods can ward off allergic reaction to peanuts and prevent peanut allergy development in some people, according to new guidelines from the National Institute of Allergy and Infectious Diseases.

Exposure via breastfeeding and early introduction can reduce sensitization , but there is still not a solid answer in terms of reducing food allergy. If you dont love peanuts, dont force yourself to eat them. However, if you dont mind them, or if you absolutely love them, feel free to include them. Tree nuts and seeds and all nuts are safe during pregnancy. There are even other known benefits of eating nuts and seeds during pregnancy and for general health. More research is still needed about the maternal diet and how it influences allergies.
