Can You Cure Food Allergies

Preventing Food Allergy In Children

Allergy prevention in children is an active area of research. Findings to date indicate that:

• prenatal there is no conclusive evidence that avoiding allergens in pregnancy will help prevent allergies in your child
• postnatal exclusive breastfeeding during the first four to six months appears to protect against the development of allergies in early childhood.
• introducing solid foods around six months is recommended, preferably while continuing to breastfeed
• breastfeeding avoidance of a food by a woman while breastfeeding is not recommended
• soymilk formula studies have shown that using soymilk formula does not prevent the development of allergies in children
• partially hydrolysed cows milk-based formula is not recommended to prevent the development of food allergy.

How Can Parents Keep Kids Safe

If your child has a food allergy, carefully read food labels so you can avoid the allergen. Ingredients and manufacturing processes can change, so it’s important to read labels every time, even for foods your child has had safely in the past. The most common allergens should be clearly labeled. But less common allergens can be hidden in ingredients like natural flavors or spices.

One thing that might not show up on a label is cross-contamination risk. Cross-contamination happens when a food you are not allergic to comes in contact with a food you are allergic to. This can happen if a manufacturer uses the same equipment to grind lots of different foods, for example. Some companies state this on their labels to alert customers to the risk of cross-contamination with messages like: “May contain peanuts,” “Processed in a facility that also processes milk,” or “Manufactured on equipment also used for eggs.” You’ll want to avoid products that have these kinds of alerts.

But companies are not required to put cross-contamination alerts on a food label. So it’s best to contact them to see if a product might been in contact with your childâs allergens. You may be able to get this information from a company website. If not, contact the company and ask.

When your child eats away from home, make sure anyone preparing food knows about the allergy and which foods to avoid. You may want to provide food that you know is safe for your child.

Referral To An Allergy Clinic

If your GP suspects a food allergy, you may be referred to an allergy clinic or centre for testing.

The tests needed can vary, depending on the type of allergy:

• if the symptoms developed quickly you’ll probably be given a skin-prick test or a blood test
• if the symptoms developed more slowly you’ll probably be put on a food elimination diet

There is more information on these tests below.

Food Allergy Rash Vs Food Intolerance

A food allergy occurs when your immune system adversely reacts to proteins in a certain food youre allergic to. This is not the same thing as a food intolerance.

Food intolerance is primarily a digestive issue that can cause symptoms similar to food allergies, except that its not life-threatening.

Non-itchy rashes from a food intolerance can also develop over time, such as chicken skin on arms. This is unlike a food allergy rash, which tends to occur within minutes or hours of eating the suspected food. Food intolerance can also cause bloating, stomach pain, and mild digestive upset.

Another key difference is that you can sometimes have small amounts of a food without a problem if you have an intolerance. With an allergy, even a small amount of the food can cause issues.

According to the AAAAI, most suspected cases of food allergies are actually intolerances. However, you dont want to take a chance with self-diagnosis. An allergist can help you determine the difference.

Is It Really A Food Allergy

A differential diagnosis is the process of telling the difference between a food allergy, a food intolerance, and other illnesses. When you go to the doctor’s office and say, “I think I have a food allergy,” they have to consider a list of other things that could cause similar symptoms and be confused with a food allergy. These include:

• Psychological triggers

Foods can get contaminated with bacteria and toxins. Tainted meat sometimes mimics a food allergy when it’s really a type of food poisoning.

Histamine can reach high levels in cheese, some wines, and in certain kinds of fish, especially tuna and mackerel, if it hasn’t been refrigerated properly. When you eat foods with a lot of histamine, you could have a reaction that looks like an allergic reaction. It’s called histamine toxicity.

Sulfites are made naturally during the fermentation of wine, and they’re added to other foods to enhance crispness or prevent mold growth. High concentrations of sulfites can pose problems for people with severe asthma. They give off a gas called sulfur dioxide, which the person breathes in while they’re eating the food. This irritates their lungs and can trigger an asthma attack. That’s why the FDA banned sulfites as spray-on preservatives for fresh fruits and vegetables. But sulfites are still used in some foods.

Yellow dye number 5 can cause hives, although that’s rare.

What Are The Benefits Of Oit

OIT offers many benefits. It may improve quality of life for both parents and their children with food allergies. It can offer greater freedom for families managing certain food allergies, lower stress, and can reduce the risk of anaphylaxis if the treatment is successful.

After reaching OIT maintenance phase, you and your child may be able to enjoy restaurants, birthday parties, holiday gatherings, and travel, and with less worry of a reaction from accidental exposure. It can help your child feel more included overall in many activities, such as school, sports, afterschool programs, and playdates.

What Are The Symptoms Of Food Allergies

Allergic symptoms may begin within minutes to an hour after eating the food. The following are the most common symptoms of a food allergy. But symptoms may occur a bit differently for each person. Symptoms may include:

• Swelling and itching of lips and mouth

• Tightness in the throat or hoarse voice

• Nausea and vomiting

• Low blood pressure

• Loss of consciousness

Anaphylaxis is a medical emergency. to get help right away. Severe allergic reactions are treated with epinephrine. If you know you have severe allergies, you should carry an emergency kit with self-injecting epinephrine or Epi-pens.

Home Remedies And Lifestyle

There is no cure for food allergies. The only sure-fire way to avoid an allergic response is to omit known allergens from your diet.

This is not always as straightforward as it may seem, as it can be difficult to identify your exact trigger out of all the foods you eat. Moreover, people with “true” food allergies are often cross-reactive to a wide range of foods.

There are tests and procedures that can help pinpoint the culpritslike skin-prick tests and elimination diets administered by an allergistbut arguably the easiest way to do so is to keep a food diary. By keeping a record of everything you eat and every time you have a reaction, you can gradually narrow down the suspects.

Once you’ve identified your food allergens, you can start building strategies to not only avoid them but reduce the risk of cross-contamination as well.

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

Food Allergies Vs Food Intolerance: What Is The Difference

It is estimated that about a quarter of the population will have an adverse reaction to food during their lifetime, especially during infancy and early childhood.

Food allergies consist of an immune system response to a disagreeable food. The body senses that a protein in a particular food may be harmful and triggers an immune system response, producing histamine to protect itself. Histamine causes allergy symptoms such as hives, coughing and wheezing. The body then remembers this immunologic reaction and when the allergen food enters the body again, the histamine response is more easily triggered. The best characterized form of food allergy is mediated by food-specific IgE antibodies.

The diagnosis of food allergies may be problematic because nonallergic food reactions, such as food intolerances, are frequently confused with food allergy symptoms. Food allergies and intolerances are often linked, but theres a clear difference between the two conditions.

A food intolerance is the bodys digestive systems response to a disagreeable food. Unlike a food allergy, which produces an immunological mechanism after consuming an allergen, a food intolerance produces a non-immunological reaction. For example, a person may have digestive issues after drinking cows milk because she is unable to digest the sugar lactose this would be called a food intolerance. If she had an immunologic response to the cows milk, that would be characterized as a food allergy.

Peanut Allergy On The Rise

Anxious parents may welcome the news. According to a FARE study, allergy to peanuts is on the rise among U.S. children, with rates more than tripling between 1997 and 2008. Overall food allergy rates, including but not exclusive to peanuts, rose 50% between 1997 and 2011, the CDC says.

While the most common food allergies among kids ages 2 and younger are to milk and eggs, “80% outgrow these two food aversions,” says Garcia-Lloret. Only 20% of children outgrow peanut allergy, making it a lifelong condition, which also has a disproportionately high rate of inducing severe, even life-threatening reactions, according to multiple studies.

Garcia-Lloret and other prominent researchers are still searching for the reasons why. “It’s likely multifactorial, involving changes to the microbiome,” she says of the body’s complex immunological ecosystem and what may be triggering it to overreact to seemingly harmless proteins in foods. Overly sanitized modern life may be at root — our love for antibacterial soaps and the overuse of antibiotics mean the body never confronts, and thus never fights off, all sorts of germs, which is what it’s designed to do. It may be itching for a fight — just the wrong one.

Food Allergies In Infants And Children

Milk and soy allergies are particularly common in infants and young children, probably because their immune and digestive systems are still developing. These allergies can appear within days to months of birth. They may not show up as hives and asthma, but rather lead to colic and perhaps blood in poop or poor growth.

Typically, the doctor sees a very unhappy colicky child who may not sleep well at night and diagnoses a food allergy partly by changing their diet, like switching from cow’s milk to soy formula. This type of allergy tends to disappear within a few years.

Doctors recommend only breastfeeding infants for the first 4-6 months, if possible, for many reasons, but there’s no proof that it prevents food allergies later in life. While some pregnant women may hope limiting their diets while they’re pregnant or breastfeeding may help their children avoid allergies, the experts disagree and don’t suggest it. Soy formula isn’t a good way to prevent allergies either.

Cross Reactivity And Oral Allergy Syndrome

When you have a life-threatening allergic reaction to a certain food, your doctor will probably recommend that you avoid similar foods, too. For example, if you react to shrimp, you’re probably allergic to other shellfish like crab, lobster, and crayfish. This is called cross-reactivity.

Another example of cross-reactivity is oral allergy syndrome. It happens in people who are highly sensitive to ragweed. During ragweed season, when they try to eat melons, especially cantaloupe, their mouths may itch. Similarly, people who have severe birch pollen allergy may also react to apple peels.

Food Allergy Rash And Anaphylaxis

The most severe type of allergic reaction is anaphylaxis, which is a life-threatening condition. This is not a complication of a food rash itself, but rather a complication of the overall allergic reaction. Hives and anaphylactic reactions often occur together, but you can have hives without having anaphylaxis.

On top of the food allergy symptoms listed above, anaphylaxis may cause:

• breathing difficulties
• severe swelling in the mouth, face, neck, and throat
• tightness in the throat
• tingling lips, hands, and feet

If your doctor recommends epinephrine shots for severe food allergies, its important to keep them on hand at all times. Even breathing in a food allergen can cause severe issues. Also, the severity of a reaction may vary just because one reaction was mild, doesnt mean the next will also be mild.

Anaphylaxis is a medical emergency. Call 911 or your local emergency services and take your epinephrine shot as soon as you experience symptoms. Antihistamines cant treat anaphylaxis because the symptoms are too severe at this stage.

Which Foods Most Often Cause Food Allergies

About 9 in 10 food allergies are caused by these foods:

Some facts about food allergies:

• Eggs, milk, and peanuts are the most common causes of food allergies in children.

• Peanuts, tree nuts, fish, and shellfish commonly cause the most severe reactions.

• Nearly 1 in 20 children under the age of 5 years have food allergies.

• From 1997 to 2007, food allergies increased by 18% among children under age 18 years.

• Most children “outgrow” their allergies. But allergies to peanuts, tree nuts, and shellfish may be lifelong.

• According to the National Institute of Allergy and Infectious Diseases, it doesn’t take much food to cause a severe allergic reaction1/44,000 of a peanut can cause a severe reaction in a highly allergic person.

What Questions Should I Ask My Doctor

You may want to ask your healthcare provider:

• What type of food intolerance do I have?
• What foods or ingredients should I avoid?
• Am I at risk for other problems?
• Should I look out for signs of complications?

A note from Cleveland Clinic

A food intolerance can cause stomach upset and other digestive problems after you consume certain foods or drinks. Having a food intolerance isnt the same as having a food allergy. Food allergies cause an immune system response that can be life-threatening. Most people with food intolerances can have small amounts of those foods without distressing symptoms. A food diary and elimination diet can help determine if you have a food intolerance.

When Should I Go To The Er

Without medical treatment, allergic reactions can be life-threatening. Go to the ER or call 911 if you experience:

• Difficulty breathing.
• Hives all over your body.
• Tingling hands, feet or lips.
• Throat swelling that constricts your airway.

A note from Cleveland Clinic

Food allergies occur when your body mistakenly triggers an immune response to certain foods. This immune response, or allergic reaction, can cause a variety of symptoms such as hives, swelling or difficulty breathing. In severe cases, you may experience a life-threatening reaction called anaphylaxis. Once you know what foods you are allergic to, the best way to manage your allergy is to avoid those specific foods. Healthcare providers can prescribe medications that reverse anaphylaxis and other allergy symptoms.

A Helpful Inflammation Analogy

Think of a glass of water. The glass is the body, and the water is the inflammation in the body. Our bodies have a baseline level of inflammation, depending upon the five contributing factors to inflammation: food, environmental allergies, environmental toxins, infectious diseases, and stress.

A childlets call him Solomoneats the Standard American diet and has several of the common chronic and recurrent common childhood illnesses including eczema, asthma, environmental allergies to tree pollen and grasses, chronic runny nose, recurrent ear infections, and constipation. He also has a significant amount of systemic inflammation.

Solomons glass of water is overflowing with inflammation, preventing his immune system from working optimally.

Since we cant cut down all the trees and dig up all the grasses, we look at the aspect of Solomons environment that we have the most control over: food. We minimize his processed and packaged foods add in more vegetables, healthy fats, and proteins replace high-sugar drinks with water and potentially, gradually remove dairy from his diet.

The higher the amount of baseline inflammation, the longer it may take to get the inflammation under control. Sometimes this means adding more medications or supplements at first, to treat the childs illness and to strengthen his or her immune system.

Sounds simple, right?
