Pay Attention To Your Infant’s Reactions

If you’re still in the breastfeeding stage, you may want to avoid certain foods if you see your infant having a bad allergic reaction like skin rashes or loose stools. But check with his healthcare provider first before making any sweeping dietary changes.

Similarly, if you’re formula-feeding, you will want to pay attention the list of ingredients on the formula label if you see your infant experiencing rashes or loose stools. He may be allergic to one of the ingredients. Check with his provider, who may recommend switching to a hypoallergenic formula.

Of course, you’ll need to watch carefully for signs of food allergies as you transition to feeding your little one solid foods.

Itâs estimated that food allergies affect up to 6 percent of children aged 0-2 years, according to The American Academy of Allergy, Asthma & Immunology . For these kids, eating certain foods triggers an immune system overreaction that can cause anything from chronic itching and eczema to sudden difficulty breathing and even life-threatening anaphylactic shock.

The problem is growingthe incidence of food allergies increased 50 percent between 1997 and 2011. Scientists arenât sure why, but theories include greater awareness among parents and doctors, lower immunity because of less exposure to bacteria, and lack of exposure to common allergens early in life.

Heres everything you need to know about food allergies in babies.

What Is An Allergy

An allergy happens when a persons immune system treats a substance like an inappropriate invader. The body will try to protect itself by releasing a chemical into the body called histamine. This chemical is what causes the symptoms that are unpleasant or even dangerous. The reaction can start very suddenly, even after being exposed to a small amount of the allergen.

Allergens can get into the body in different ways. They can be:

• ingested as food ,
• ingested as medication ,
• injected by an insect sting , or
• absorbed through the skin .

Cashews, Peppercorns You are correct that mango is in the same family as cashew and pistachio. Many foods share common ancestry or have similar proteins, but this does not necessarily translate to allergy. Mango allergy is relatively uncommon and when it occurs it is not necessarily related to having a cashew allergy.

Are Food Allergy And Food Intolerance The Same

Food allergies and food intolerance are not the same.

An allergy involves the body’s immune system and can be serious. An intolerance is a reaction that doesnt involve the immune system. If you have a food intolerance, you may experience unpleasant symptoms after eating the problem food, but you will not have a dangerous reaction.

A doctor can arrange allergy tests to diagnose food allergies. Food intolerances will not show up on these tests.

Smart Feeding Strategies For Starting Solids

According to the American Academy of Pediatrics, offering your baby allergenic foods is OK starting at four to six months just be sure to watch for any allergic reaction .

Indeed, several studies show that the early introduction of highly allergenic food can lead to a lower rate of food allergies, says Katie Marks-Cogan, M.D, co-founder and Chief Allergist of Ready, Set, Food. This age lets you mold the immune system away from allergies.

Introduce new foods one at a time, two to three days apart. Record everything that your baby eats for several weeks as well as any related symptoms . Visit your doctor if you notice a concerning pattern.

If your infant is diagnosed with asthma, eczema, or a food allergy, follow your doctor’s instructions on the timing of solid foods, says Dr. Greer.

Most Common Food Allergens For Babies

Most severe allergic reactions to foods will happen very soon after exposure. However, some milder reactions may take up to a few hours to become apparent.

Food allergies may be more common in families with a history of allergies and associated conditions, like asthma, eczema, or even hay fever.

The great majority of food-related allergic reactions are caused by one of the following:

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 doctorâs 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 to introduce honey, which can cause a potentially serious disease called infant botulism. Ask your pediatrician for guidance.

Can People Outgrow Food Allergies

About 80% of people will outgrow a milk, egg, wheat, or soy allergy. These are much more common in childhood. About 20% of people will outgrow a peanut, tree nut, fish, or shellfish allergy. However, this is not something you want to experiment with on your own. Talk to your allergist and they can track your allergy over time.

How Is A Food Allergy Diagnosed

If your child might have a food allergy, the doctor will ask about:

• your child’s symptoms
• the time it takes between eating a particular food and the start of symptoms
• whether any family members have allergies or conditions like eczema and asthma

The doctor might refer you to an , who will ask more questions and do a physical exam. The allergist probably will order tests to help make a diagnosis, 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. A positive test to a food shows that your child might be sensitive to that food.
• blood tests to check the blood for IgE antibodies to specific foods

Your child may need to stop taking some medicines 5 to 7 days before the skin test because they can affect the results. Check with the allergist’s office if you are unsure about what medicines need to be stopped and for how long.

If the test results are unclear, the allergist may do a food challenge:

• During this test, a person slowly gets increasing amounts of the potential food allergen to eat while being watched for symptoms by the doctor. The test must be done in an allergist’s office or hospital with access to immediate medical care and medicines because a life-threatening reaction could happen.

Food challenge tests are also done to see if people have outgrown an allergy.

Delayed Symptoms & Fpies

FPIES is a type of food allergy in children that can be severe and life-threatening. Unlike most allergic reactions , FPIES allergic reactions occur within hours after consuming a particular food. For this reason, FPIES is sometimes known as a delayed food allergy. The most common food culprits of FPIES are cows milk products , soy, oats, and rice, followed by other foods such as avocado, banana, barley, eggs, green beans, peas, meats, poultry, seafood, squash, and sweet potatoes. FPIES is extremely rare in exclusively-breastfed infants.3

The classic presentation of FPIES is an infant who recently switched from breast milk to formula or started solids and begins vomiting between 1 to 4 hours and experiencing diarrhea between 5 to 10 hours after eating the specific food culprit. Other symptoms include low blood pressure, low body temperature, extreme pallor, repetitive vomiting, and significant dehydration. Thankfully, most cases of FPIES will completely resolve during toddlerhood. If a child has been diagnosed with FPIES, they must be followed closely by an allergist or immunologist.

What To Do If Your Baby Has Been Diagnosed With A Food Allergy

If your baby or toddler is diagnosed with a food allergy, it’s best to begin avoiding that specific food immediately, even if her allergic reaction isn’t a serious one. You’ll need to be very mindful of what foods your baby or toddler is going to eat at all times, especially if it’s food you didn’t prepare.

Start Gradually To Identify Any Food Allergies

Itâs 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 wonât 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. Donât 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 donât add anything else new.

Causes Of Food Allergies In Children

Researchers are still investigating what causes food allergies. However, it is known that children must first be exposed to foods that can cause an allergic reaction.

During the initial exposure to a certain food, the body creates antibodies. Being exposed to the food a second time triggers the immune response, as the antibodies recognize the food in the body.

There may also be a genetic component to food allergies. Having parents or other family members with food allergies can increase the likelihood that a child will have a food allergy.

Dining Out With Food Allergies

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

The American Dietetics Association offers these tips for dealing with foodallergies 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.

Alternately, there are several types of allergy cards available on theinternet that can be customized with your child’s personal information. Oneexample is the Food Allergy Buddy Dining Card, promoted by the NationalRestaurant Association.

Common Foods That Cause Allergies

Any food could potentially cause an allergy. The following foods, though, are those that most commonly cause allergies.

The challenge is discovering which foods your baby is allergic to. Allergy testing in young infants is often not reliable. One way to determine which foods are a problem for your baby is to keep a food diary of the foods you eat along with a record of your babys symptoms. You may see a pattern develop of worsening symptoms whenever you eat certain foods.

Treatment For Food Allergies

EpiPen

Antihistamines such as ceftirizine can be helpful for minor allergic reactions, but if your child is in any danger of having a severe reaction, you’ll want to have an EpiPen on hand at all times.

An EpiPen is a device that automatically administers an emergency shot of epinephrine to stop an allergic reaction. Your child’s doctor will prescribe the right EpiPen for your child and show you how to use it.

Anyone who takes care of your child should also have access to an EpiPen in case your child needs it.

In some cases if they’re very responsible an older child can carry the epinephrine injector themselves. Talk with your child’s doctor about whether this is recommended for your child.

Allergy shots

Allergy shots allergen immunotherapy can be beneficial for some children with certain allergies. The child is given injections containing small amounts of the allergen, usually starting on a weekly schedule and then every two weeks, three weeks, and finally four weeks. The regimen of monthly shots is usually maintained for three to five years, after which allergic symptoms don’t return. These shots are given under the supervision of a doctor.

Oral Immunotherapy

Food supplementation

There’s now an FDA-approved treatment for peanut allergies called Palforzia. It’s not a remedy to be used when a child is having an allergic reaction, but a treatment regimen to help reduce the severity of allergic reactions, including anaphylaxis.

Swelling Of The Face Lips And Eyes

Your baby may take on a puffy look in their face, especially in the lips and around the eyes, if they are having an allergic reaction to a food. This is called angioedema.

Treating the allergy with antihistamines should help the angioedema go away. Without treatment, the swelling will likely go away within a few days.

This symptom is considered mild unless your baby also has swelling in the tongue and throat.

How Fast Can Allergic Reactions Happen

Fact Checked

An allergic reaction can be as mild as a sense of slight itching or as severe as massive swelling that makes it impossible for the person to breathe. Allergies became more common in children in the United States between 1997 and 2011, according to the Centers for Disease Control and Prevention 1. Treatment for allergies can range from observation to medications, and in cases of the most serious reaction — anaphylaxis — extensive emergency treatment. Treatment is dictated by the speed and severity of the allergic reaction.

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

How Do You Prevent Food Allergies In Babies

If you are not allergic to any food then you need to avoid possible allergens as it is not proven that this may prevent allergies in your baby. Breastfeeding has been found to reduce the risk of an allergic reaction in your baby. However, if your baby seems to be allergic to breast milk, it means they are allergic to the proteins from the foods you have eaten as they are passed on to your milk.

It has been proven that breastfeeding between the 4 to 6 months will reduce your babys risk of developing eczema, an allergy to cows milk, and wheezing. At this age introduce your baby to solid foods with single ingredients like squash baby food, rice cereal, or apple. Try new foods with a gap of a few days in between because then you can find out what kind of foods they are allergic to. Some people avoid giving their baby higher risk foods like peanuts and eggs but experts say it will only increase their risk of developing good allergies.

Seek Medical Attention For Serious Symptoms

If your baby is acting normally but has a mild rash or some hives, you could give your baby an antihistamine. Diphenhydramine can provide comfort, but second-generation antihistamines like cetirizine and loratadine last longer and are less likely to make your baby sleepy, Dr. Tam says.

If your baby is vomiting, coughing, having difficulty swallowing , or acting very sleepy, seek immediate medical attention. Try to get a doctor on the phone or go to the emergency department, Dr. Tam says.

What Is A Food Intolerance

People often confuse food allergies with food intolerance. The symptoms of food intolerance can include burping, indigestion, gas, loose stools, headaches, nervousness, or a feeling of being “flushed.” But food intolerance:

• doesn’t involve the immune system
• can happen because a person can’t digest a substance, such as lactose
• can be unpleasant but is rarely dangerous
