Food Allergies in Children | Johns Hopkins Medicine

What is food allergy?

A food allergy is an abnormal response of the body to a certain food. It is important to know that this is different than a food intolerance, which does not affect the immune system, although some of the same symptoms may be present.

What causes food allergy?

Before having a food allergy reaction, a sensitive child must have been exposed to the food at least once before, or could also be sensitized through breast milk. It is the second time your child eats the food that the allergic symptoms happen. At that time, when IgE antibodies react with the food, histamines are released, which can cause your child to experience hives, asthma, itching in the mouth, trouble breathing, stomach pains, vomiting, and/or diarrhea.

What is the difference between food allergy and food intolerance?

Food allergy causes an immune system response, causing symptoms in your child that range from uncomfortable to life-threatening. Food intolerance does not affect the immune system, although some symptoms may be the same as in food allergy.

What foods most often cause food allergy?

Approximately 90 percent of all food allergies are caused by the following eight foods:

  • Milk

  • Eggs

  • Wheat

  • Soy

  • Tree nuts

  • Peanuts

  • Fish

  • Shellfish

Eggs, milk, and peanuts are the most common causes of food allergies in children, with wheat, soy, and tree nuts also included. Peanuts, tree nuts, fish, and shellfish commonly cause the most severe reactions. Nearly 5 percent of children under the age of five years have food allergies. From 1997 to 2007, the prevalence of reported food allergy increased 18 percent among children under age 18 years. Although most children "outgrow" their allergies, allergy to peanuts, tree nuts, fish, and shellfish may be lifelong.

What are the symptoms of food allergy?

Allergic symptoms may begin within minutes to an hour after ingesting the food. The following are the most common symptoms of food allergy. However, each child may experience symptoms differently. Symptoms may include:

  • Vomiting

  • Diarrhea

  • Cramps

  • Hives

  • Swelling

  • Eczema

  • Itching or swelling of the lips, tongue, or mouth

  • Itching or tightness in the throat

  • Difficulty breathing

  • Wheezing

  • Lowered blood pressure

According to the National Institute of Allergy and Infectious Disease, it does not take much of the food to cause a severe reaction in highly allergic people. In fact, as little as 1/44,000 of a peanut kernel can cause an allergic reaction for severely allergic individuals.

The symptoms of food allergy may resemble other problems or medical conditions. Always consult your child's doctor for a diagnosis.

Treatment for food allergy

There is no medication to prevent food allergy. The goal of treatment is to avoid the foods that cause the symptoms. After seeing your child's doctor and finding foods to which your child is allergic, it is very important to avoid these foods and other similar foods in that food group. If you are breastfeeding your child, it is important to avoid foods in your diet to which your child is allergic. Small amounts of the food allergen may be transmitted to your child through your breast milk and cause a reaction.

It is also important to give vitamins and minerals to your child if he or she is unable to eat certain foods. Discuss this with your child's doctor.

For children who have had a severe food reaction, your child's health care provider may prescribe an emergency kit that contains epinephrine, which helps stop the symptoms of severe reactions. Consult your child's doctor for further information.

Some children, under the direction of his or her health care provider, may be given certain foods again after three to six months to see if he or she has outgrown the allergy. Many allergies may be short-term in children and the food may be tolerated after the age of 3 or 4.

Milk and soy allergy

Allergies to milk and soy are usually seen in infants and young children. Often, these symptoms are unlike the symptoms of other allergies, but, rather, may include the following:

Often, your child's doctor will change your baby's formula to a soy formula or breast milk if it is thought he or she is allergic to milk. If your child has problems with soy formula, your child's health care provider might change him or her to an easily digested hypoallergenic formula.

The symptoms of a milk or soy allergy may resemble other problems or medical conditions. Always consult your child's doctor for a diagnosis.

Prevention of food allergies

The development of food allergies cannot be prevented, but can often be delayed in infants by following these recommendations:

  • If possible, breastfeed your infant for the first six months.

  • Do not give solid foods until your child is 6 months of age or older.

  • Avoid cow's milk, wheat, eggs, peanuts, and fish during your child's first year of life.

Dining out with food allergies

If your child has one or more food allergies, dining out can be a challenge. However, it is possible to have a healthy and satisfying dining-out experience; it just takes some preparation and persistence on your part.

The American Dietetics Association offers these tips for dealing with food allergies when your family is eating away from home:

  • Know what ingredients are in the foods at the restaurant where you plan to eat. When possible, obtain a menu from the restaurant ahead of time and review the menu items.

  • Let your server know from the beginning about your child's food allergy. He or she should know how each dish is prepared and what ingredients are used. Ask about preparation and ingredients before you order. If your server does not know this information or seems unsure of it, ask to speak to the manager or the chef.

  • Avoid buffet-style or family-style service, as there may be cross-contamination of foods from using the same utensils for different dishes.

  • Avoid fried foods, as the same oil may be used to fry several different foods.

Another strategy for dining out with food allergies is to give your server or the manager a food allergy card. A food allergy card contains information about the specific items your child is allergic to, along with additional information, such as a reminder to make sure all utensils and equipment used to prepare your meal is thoroughly cleaned prior to use. You can easily print these cards yourself using a computer and printer. If your child is eating out with friends and you are not going to be present, give your child a food allergy card (or make sure the adult in charge has one) to give to the server.

Alternately, there are several types of allergy cards available on the internet that can be customized with your child's personal information. One example is the Food Allergy Buddy Dining Card, promoted by the National Restaurant Association.

The Food Allergy Initiative, in conjunction with the National Restaurant Association and the Food Allergy and Anaphylaxis Network, has developed the Food Allergy Training Program for Restaurants and Food Services. This training program was developed to help restaurants and other food service outlets to ensure their customers, including those with food allergies, will receive a safe meal prepared to customer specifications.

Starting to feed a baby solid foods is an exciting milestone for parents. However, it comes with a lot of questions and concerns, especially about food allergies. What foods are most likely to cause allergies in babies? How do you avoid them?

Emerging research has shown that introducing multiple foods together is safe, and may help the immune system have a lower risk of developing food allergies, but more studies are needed. Check with your doctor for what’s best for your baby.

Start Gradually to Identify Any Food Allergies

It’s most important to introduce a baby to new foods gradually, one at a time, in case of food allergies. If not, a parent may have trouble tying an allergy to a specific new food. For example, if you give your baby three new foods over the course of a day and they develop an allergic reaction, you won’t know which of the foods provoked it.

The type of food or the order in which food is introduced is not much of a concern, as long as the foods you are offering are healthy and well-balanced for the baby. Each time you offer a new food, you should wait three to five days before adding another new item to the menu. Don’t eliminate the other foods your baby is eating during that time; you already know these are safe because the child has not had any food reactions up until now. Just don’t add anything else new.

Babies and Allergies: The Top 8 Allergenic Foods

With any new food, you’ll want to be on the lookout for any allergic reactions. There are more than 160 allergenic foods; certain foods may be more allergenic than others. The following eight foods and food groups are known to possibly cause problems with allergic reactions possibly up to 90% of the time. 

  • Cow's milk
  • Eggs
  • Peanuts
  • Tree nuts (such as walnuts or almonds)
  • Fish
  • Shellfish
  • Soy
  • Wheat

New nutrition guidelines from the American Academy of Pediatrics say it's okay to introduce these allergy-causing foods when your baby is ready to eat solids. There is no evidence that waiting until the baby is older prevents food allergy. If you believe your baby has an allergic reaction to a food, such as diarrhea, rash, or vomiting, talk with your child's doctor about the best choices for the diet.

Within a few months of starting solid foods, your baby's daily diet should include a variety of foods, such as breast milk, formula, or both; meats; cereal; vegetables; fruits; eggs; and fish.

Food Allergy Symptoms to Watch for in Your Baby

Food allergy symptoms usually appear very soon after the food is eaten -- within a few minutes to a couple of hours. If you’re introducing a new food to your baby, keep an eye out for these symptoms:

  • Hives or welts
  • Flushed skin or rash
  • Face, tongue, or lip swelling
  • Vomiting and/or diarrhea
  • Coughing or wheezing
  • Difficulty breathing
  • Loss of consciousness

Severe Food Allergy Symptoms: When to Call 911

Severe allergic reactions can be fatal very quickly. If your baby is having trouble breathing/wheezing, has swelling on their face/lips, or develops severe vomiting or diarrhea after eating, immediately call 911. You can inform your pediatrician at a later time.

 

Dealing With Mild Food Allergies in Baby

If you see mild symptoms, such as hives or a rash, contact your pediatrician for further evaluation. The doctor might refer you to an allergist (allergy specialist doctor), who will ask more questions and do a physical exam. The allergies may order diagnostic tests such as:

  • A skin test. This test involves placing liquid extracts of food allergens on your child's forearm or back, pricking the skin, and waiting to see if reddish raised spots form within 15 minutes. A positive test to a food only shows that your child might be sensitive to that food.
  • Blood tests to check the blood for IgE antibodies to specific foods

Remember, just because a baby’s initial allergic reaction to a new food may be mild, it may get worse upon following exposures. Talk to your pediatrician about any food allergy symptoms in your baby.

Some allergies go away with time. Egg and milk allergies often go away as children get older, but peanut, tree nut, and shellfish allergies tend to persist.  That said, research shows that in the case of peanut allergies, peanut immunotherapy drops administered under the tongue are safe and effective as treatment for peanut allergy, even in children as young as 1. They were also found to help significantly desensitize the patients to peanuts.

The Family Food-Allergy Connection

If there is a family food allergies, your baby has an increased risk of also developing allergies, although it is not a certainty. If you have the allergies, the odds are 50-50 for them to have them as well. 

It’s best to introduce the 8 allergens gradually, at one-to-two week intervals over time so that you can recognize if an allergy develops.

Protecting Baby Against Food Allergies: Easy Does It

In a reversal of earlier policy, the American Academy of Pediatrics is now recommending that potential allergens be introduced to your infant earlier rather than later. In doing so, the move may actually help prevent them from developing allergies to those foods.

Breastfeeding you baby for 4-6 months is the best way to prevent a milk allergy. Remember that breast milk or formula is higher in nutrition. When you begin to introduce whole milk, you should do so under a doctor’s supervision. Yogurt and soft cheeses are fine, because the proteins in these dairy products are broken down and less likely to cause tummy trouble.

The AAP now advises that, in the case of infants who are at high risk of allergies, peanuts should be introduced between 4-6 months. Infants at highest risk of developing peanut allergies are those with eczema or egg allergies or both. It was originally believed that introducing your baby to the foods when they are older might make any reactions more manageable.

Other potential allergens such as tree nuts and fish should be introduced over a period of time as you introduce your baby to solid foods, between 6 and 9 months

You should wait until at least age 1 (some experts say age 2) to introduce honey, which can cause a potentially serious disease called infant botulism. Ask your pediatrician for guidance.

 

Food allergies in young children!

Food allergies in young children!

Every mother remembers the calm days of pregnancy, where you could eat various foods in your diet without dieting. The main table during pregnancy should be as balanced as possible, fortified and the necessary ratio of proteins, fats, carbohydrates. There comes a happy moment in life, this is the birth of a baby. Acquaintance of mother and child, caring for the baby, providing the necessary conditions for caring for the baby, as well as creating the most favorable conditions.

Very often, young parents face the first difficulties in the neonatal period (such as intestinal colic), in early childhood, such manifestations as rashes on the body, stool disorders (loose stools / constipation).

The most frequently asked questions of parents we will consider in this article:

  1. How does a food allergy manifest itself?
    2. What is the duration of manifestation of external signs?
    3. Is it worth giving up breastfeeding in favor of artificial (hydrolyzed and amino acid mixtures) or switching to goat's milk?
    4. Blood streaks in the stool: is it worth going to the infectious disease hospital for inpatient care?

Food allergy is a food-induced reaction that causes a pathological reaction based on immune mechanisms (specific IgE-mediated reactions, cellular immune response (non-IgE-mediated) or a combination of both - a mixed type reaction).

As a food allergen, there can be any substances, most often of a protein nature, that stimulate the production of IgE.

The most common foods that cause allergic reactions are cow's milk, chicken eggs, peanuts, tree nuts, fish, seafood, wheat, soy, and beef.

The most significant allergen is Cow's milk protein, which according to clinical guidelines is 2-3% among infants. With age, tolerance develops in 80% of sick children, by the age of 6 years, the incidence decreases by less than 1%.
Any protein component of milk can cause sensitization, but most often: beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin and gamma globulin, alpha-casein and beta-casein.

Food allergy is a symptom complex of diseases and is not a nosological diagnosis.
Therefore, the clinical and etiological significance of food allergy is taken into account, it is included in the full clinical diagnosis after the designation of the nosological form.

  • Atopic dermatitis
  • Allergic urticaria
  • Allergic gastroenteritis and colitis

Laboratory diagnostics:

  • IgE (sIgE) - immunoglobulin E, specific immunoglobulin

The main function of IgE is to provide an individual immune response of the body to the introduction of an irritant (antigen) with a certain biological activity

  • Food panel

In case of food allergy in young children, manifestations in the form of constant itching (characteristic of any age period), skin syndrome are more common. Atopic dermatitis in young children is infancy, during this period the exudative form of the disease predominates. The clinical picture is represented by erythematous spots, papules, vesicles on the forehead, cheeks, scalp, accompanied by intense itching, swelling, weeping. Pronounced red dermographism. Most often, rashes are localized on the extensor and flexor surfaces of the limbs.

The duration of rashes depends on the timely start of treatment, as well as the complete exclusion of allergens (food). In children of the first year of life, the most common allergen is cow's milk protein.
Breastfed infants develop a clinically significant allergy to CMP due to the passage of dietary proteins into breast milk. I often see surprise in the eyes of young mothers and the rejection of the recommendation to exclude cow's milk protein. Counter questions: what exactly to use in the diet for mom? Dear mothers, a balanced diet for a nursing mother should be varied, complete and as natural as possible. The use of cereals (rice, buckwheat, corn, oatmeal, etc.), soups, meat products (turkey, chicken, pork), quail or chicken eggs, green fruits, etc. Therefore, the absence of whole cow's milk will not affect your menu variety in any way.

Should I give up breastfeeding?

Indeed, mothers often ask such questions. My answer is no! Breastfeeding is the key to the full development of the child. Only in the case when breastfeeding is impossible (complete hypogalactia of the mother, impossibility of breastfeeding due to congenital diseases (example: congenital malformation of cleft lip and palate), the presence of chronic infectious diseases in the mother are life-threatening for the child.

In the case where it is not possible to store the GW. The recommendations use hydrolyzed mixtures, or amino acids!
Hypoallergenic mixtures do not belong to clinical nutrition, they are prescribed only for children prone to developing allergies (taking into account history and heredity).
Soy Blend is also not a health food and can cause a cross reaction!

Switching to goat's milk is not the smart way. Since in this case, goat milk can act as a cross-allergen, causing cross-allergic reactions in patients with an allergy to CMP, and is an independent allergen, causing severe reactions in patients who are tolerant to cow's milk. And also the main allergens of milk practically do not lose their biological activity after boiling, pasteurization, ultra-high temperature treatment.

Blood streaks in the stool: is it worth going to the infectious disease hospital for inpatient care?

Gastrointestinal manifestations are manifestations of the digestive organs. Food allergies are not only when there are rashes on the body. An allergen that passes through the gastrointestinal tract can cause dyspeptic manifestations (regurgitation, intestinal colic, abdominal pain, vomiting, blood streaks in the stool). Such children very often end up in an infectious diseases hospital. Receive symptomatic therapy, which brings only temporary improvement. If not diagnosed in time, unfortunately, this can lead to irreversible consequences.

If your baby does not have subfebrile / febrile body temperature, for a long time there is no improvement after a course of medication prescribed by your doctor, the presence of streaks of blood, mucus, discoloration in the stool, then most likely your child has a Gastrointestinal form of food allergy.

Gastrointestinal form of food allergy can occur both on breastfeeding and on artificial.
For mothers following a therapeutic diet with complete exclusion of CMP. Children with artificial feeding, the transition to clinical nutrition. The effect of timely treatment comes quickly. Following a diet in the future leads to a rapid recovery of the gastrointestinal tract.

Food allergies in children - symptoms, treatments, diet

Food allergies in children any dish or its individual components.

What are its causes, what are the risk factors, and what food to choose in case of an allergic reaction - read in this material.

Food allergy symptoms

The causes of food intolerance are due to the fact that the immune system "incorrectly" recognizes them as potentially dangerous, and produces an excess of protective antibodies. Excessively violent reaction leads to the fact that the child develops an allergy to certain types of food. 1.3

Symptoms of food allergy in children are different. But most often, food allergies manifest themselves on the part of the skin - itching, a feeling of tightness and dryness. Local swelling may occur on the skin, a rash (urticaria), redness, blisters may appear. In second place in terms of frequency of manifestation - reactions from the respiratory system. Runny nose, nasal congestion, sore throat, cough of varying intensity. Also, reactions from the organs of the gastrointestinal tract can indicate food allergies. A very young child begins to be disturbed by colic, dyspepsia, stool disorders from diarrhea to constipation. Older children complain of nausea, vomiting, abdominal pain, a feeling of scratching in the throat, behind the sternum.

Do not forget about the general symptoms of food allergies: the child becomes lethargic, capricious, sleeps poorly, does worse in school (or psycho-emotional development), is prone to daytime sleepiness. 2.3

Causes of food allergies

Newborns and young children, if predisposed, may suffer from allergies due to their physiological characteristics. The fact is that a child is born with an immature gastrointestinal tract, the intestinal walls are permeable to many substances, the enzyme system is still imperfect. Therefore, it is difficult for the body to cope with the digestion of proteins. The body seems to be in a state of constant "combat readiness" and the ingestion of even a small amount of allergens leads to a response from the immune system and the development of a violent allergic reaction. 1.2

In older children, many internal and external conditions become risk factors. For example, heredity - after all, if one of the child's parents suffered from an allergic disease, then with a high degree of probability the child will also be given a tendency to it. Unfavorable environmental factors influence - polluted atmosphere, car exhausts, lack of green plants in cities. Very often, a violation of the immune system in the form of an allergic reaction occurs in children with a labile, mobile psyche, with sharp transitions from friendliness and calmness to crying and back. Finally, bad habits, both in children and mothers during pregnancy, become an important factor. This is incorrectly introduced complementary foods and early introduction of potentially allergenic foods into the child's diet: citrus fruits, nuts, chocolate, berries, honey, and, of course, the habit of children to eat only something tasty (usually unhealthy; chocolate, carbonated drinks, fast food ) 2,3,4

List of products that provoke allergies

Due to the extreme individuality of the immune system, it is almost impossible to predict its reaction. However, there is a rough list of foods classified into groups depending on their allergenicity - that is, the ability to cause a sharp reaction from the immune system and allergy symptoms. It is important to remember that it is not necessary that any product from the first column will cause a reaction. Like any low allergenic product, in some cases, it can cause an overreaction to it. 2,3,4

Examples of the most typical exoallergens

Highly allergenic products Foods of average allergenicity Low Allergy Products
all citrus fruits, strawberries, strawberries, raspberries, blackberries, pineapples. peaches, cranberries, lingonberries, cherries, blueberries, black currants. pears, gooseberries, dried apricots, plums, white currants, apples and pears.
carrots, tomatoes, bell peppers, radishes. potatoes, beets, peppers, peas, corn. broccoli, green peas, zucchini, squash, white and cauliflower, cucumbers, pumpkin.
eggs, sausages and sausages, chicken, sea fish. beef, rabbit, pork. lamb.
whole cow's milk, cheeses, yoghurts with additives. fermented milk products.
wheat, rye. buckwheat, oats, rice, peas, beans. barley, millet.
coffee, cocoa, chocolate, nuts, honey. xylitol, fructose
mushrooms, carbonated drinks, packaged juices. vegetable oil.

Diagnosis established

The diagnosis of this allergy, as well as the search for the causes that caused it, requires a careful and serious approach on the part of parents. The younger the child, the easier it is to find foods that cause illness. For this, two conditions must be met.

The first thing is to put a child or mother on a hypoallergenic diet if she is breastfeeding - a detailed nutrition plan will be helped by an allergist together with a pediatrician. Please note that during an exacerbation, the diet will be extremely strict, the so-called elimination diet - aimed at removing the allergen and reaction products to it with the complete elimination of potential and cross allergens. The duration of such a diet is determined by the doctor. When the exacerbation fades, the diet gradually expands due to safe foods. 3.4

And the second thing is to start keeping a special food diary in which to record everything that was eaten and drunk by the child during the day, as well as what was cooked and how. At the first sign of an allergic reaction, suspicious foods should be eliminated one at a time (or from the mother's diet if the baby is breastfed). After elimination, within a few days, it is worth observing the reaction, if the manifestations of allergies decrease, then the product is really not suitable for the child - it should be avoided. If the child is very small, then the diary is kept according to the opposite principle: all foods that are introduced as complementary foods are recorded in it. The name of the product, the quantity, the time of eating and the reactions of the body are recorded over the next few days (the attending physician will determine the specific timing of observation). Next, the doctor will need to check and confirm the preliminary diagnosis by conducting special tests and analyzes.

Emergency measures for food allergies

The first step is to assess the severity of food allergies.

For any symptoms, the first step is to avoid contact with a specific familiar allergen or any suspicious food or drink.

If the symptoms of allergy are mild - itching, redness of the skin, then you can give the child an antihistamine, which was previously recommended by the doctor for such cases. In addition, you must also call the local pediatrician and carefully monitor the condition of the child.
