When you ponder of allergies, you might picture lots of sneezing and runny noses.

But unlike an allergy to spring flowers, a nut or peanut allergy can cause difficulty breathing and other extremely serious health problems. That’s why it’s very important for someone with a nut or peanut allergy to avoid eating nuts and peanuts, which can be tough because they’re in lots of foods.

What Are the Signs & Symptoms of a Nut Allergy?

When someone with a peanut or tree nut allergy has something with nuts in it, the body releases chemicals love histamine (pronounced: HISS-tuh-meen).

This can cause symptoms such as:

  1. trouble breathing
  2. dizziness or fainting
  3. vomiting
  4. a drop in blood pressure
  5. sneezing
  6. diarrhea
  7. hives
  8. hoarseness
  9. itchy, watery, or swollen eyes
  10. coughing
  11. throat tightness
  12. wheezing
  13. swelling
  14. stomachache
  15. anxiety or a feeling something bad is happening

Reactions to foods, love peanuts and tree nuts, can be diverse.

What causes cashew nut allergy

It every depends on the person — and sometimes the same person can react differently at diverse times.

In the most serious cases, a nut or peanut allergy can cause anaphylaxis (say: an-uh-fuh-LAK-sis). Anaphylaxis is a sudden, life-threatening allergic reaction. A person’s blood pressure can drop, breathing tubes can narrow, and the tongue can swell.

People at risk for this helpful of a reaction own to be extremely careful and need a plan for handling emergencies, when they might need to use special medicine to stop these symptoms from getting worse.

Tree Nut Substitutions

How Is an Allergic Reaction Treated?

Nut and peanut allergies can cause a severe reaction called anaphylaxis. Anaphylaxis may start with some of the same symptoms as a less severe reaction, but then quickly get worse, leading someone to own trouble breathing, feel lightheaded, or to pass out.

If it is not treated correct away, anaphylaxis can be life-threatening.

If you own a peanut or tree nut allergy (or any helpful of serious food allergy), the doctor will desire you to carry an epinephrine auto-injector in case of an emergency.

An epinephrine (pronounced: eh-puh-NEH-frin) auto-injector is a prescription medicine that comes in a little, easy-to-carry container. It’s simple to use. Your doctor will show you how. Hold the epinephrine with you, not in a locker or in the nurse’s office.

Every second counts in an allergic reaction. If you start having serious allergic symptoms, love swelling of the mouth or throat or trouble breathing, use the epinephrine auto-injector correct away.

Also use it correct away if your symptoms involve two diverse parts of the body, love hives with vomiting. Then call and own someone take you to the emergency room. You need to be under medical supervision because even if the worst seems to own passed, a second wave of serious symptoms can happen.

The doctor can also give you an allergy action plan, which helps you prepare for, recognize, and treat an allergic reaction.

Share the plan with anyone else who needs to know, such as relatives, school officials, and coaches. Also consider wearing a medical alert bracelet.

Keeping epinephrine on hand at every times should be just part of your action plan. It’s also a excellent thought to carry an over-the-counter (OTC) antihistamine as this can assist treat mild allergy symptoms. But never use as a replacement for epinephrine shot in life-threatening reactions.

Always use the epinephrine shot as the first treatment.

Cross Reactivity: Do You Need to Avoid Other Foods?

Cross-reactivity occurs when the proteins in one food are similar to the proteins in another. When that happens, the body’s immune system sees them as the same.

Tree nuts are in a diverse plant family than peanuts. Peanuts are legumes and are not related to tree nuts (almonds, walnuts, cashews, etc.). However, about 35% of peanut-allergic toddlers in the U.S. own or will develop a tree nut allergy. Doctors often recommend that young children avoid tree nuts if they are allergic to peanuts.

This is because it is fairly common to be «co-allergic» to tree nuts if a kid is allergic to peanuts.

There is a high degree of cross-reactivity between cashew and pistachio and between walnut and pecan. Most people who are allergic to one tree nut are not allergic to every tree nuts. But some doctors will advise their patients to avoid every tree nuts if allergic to one or more tree nuts. Check with your doctor to discover out if you need to avoid every tree nuts.

Have an Emergency Plan

If you own a nut or peanut allergy, you and a parent should create a plan for how to handle a reaction, just in case.

That way your teachers, the school nurse, your basketball coach, your friends — everyone will know what a reaction looks love and how to respond.

To immediately treat anaphylaxis, doctors recommend that people with a nut or peanut allergy hold a shot of epinephrine (say: eh-puh-NEH-frin) with them. This helpful of epinephrine injection comes in an easy-to-carry container. You and your parent can work out whether you carry this or someone at school keeps it on hand for you. You’ll also need to identify a person who will give you the shot.

You might desire to own antihistamine medicine on hand too for mild reactions. If anaphylaxis is happening, this medicine is never a substitute for epinephrine.

After getting an epinephrine shot, you need to go to the hospital or other medical facility, where they will hold an eye on you for at least 4 hours and make certain the reaction is under control and does not come back.

Living With Peanut or Tree Nut Allergy

If allergy skin testing shows that you own a peanut or tree nut allergy, an will provide guidelines on what to do.

The best way to prevent a reaction is to avoid peanuts and tree nuts. Avoiding nuts means more than just not eating them. It also means not eating any foods that might contain tree nuts or peanuts as ingredients.

The best way to be certain a food is nut free is to read the label.

Manufacturers of foods sold in the United States must state on their labels whether foods contain peanuts or tree nuts. Check the ingredients list first.

After checking the ingredients list, glance on the label for phrases love these:

  1. "may contain tree nuts"
  2. "produced on shared equipment with tree nuts or peanuts"

People who are allergic to nuts should avoid foods with these statements on the label. Although these foods might not use nut ingredients, the warnings are there to let people know the food may contain little traces of nuts. That can happen through something called "cross-contamination." This is when nuts get into a food product because it is made or served in a put that uses nuts in other foods.

Manufacturers are not required to list peanuts or tree nuts on the label when there might be accidental cross-contamination, but numerous do.

Some of the highest-risk foods for people with peanut or tree nut allergy include:

  1. Cookies and baked goods. Even if baked goods don’t contain nut ingredients, it is possible that they came into contact with peanut or tree nuts through cross-contamination. Unless you know exactly what went into a food and where it was made, it’s safest to avoid store-bought or bakery cookies and other baked goods.
  2. Asian, African, and other cuisine. African and Asian (especially Thai, Chinese, and Indian) foods often contain peanuts or tree nuts.

    Mexican and Mediterranean foods may also use nuts, so the risk of cross-contamination is high with these foods.

  3. Ice cream. Unfortunately, cross-contamination is common in ice cream parlors because of shared scoops. It’s also a possibility in soft-serve ice cream, custard, water ice, and yogurt shops because the same dispensing machine and utensils are often used for lots of diverse flavors. Instead, do as you would for candy: Purchase tubs of ice cream at the supermarket and be certain they’re made by a large manufacturer and the labels indicate they’re safe.
  4. Candy. Candies made by little bakeries or manufacturers (or homemade candies) may contain nuts as a hidden ingredient.

    The safest plan is to eat only candies made by major manufacturers whose labels show they are safe.

  5. Sauces. Numerous cooks use peanuts or peanut butter to thicken chili and other sauces.

Always be cautious. Even if you’ve eaten a food in the past, manufacturers sometimes change their processes — for example, switching suppliers to a company that uses shared equipment with nuts. Because ingredients can change, it’s significant to read the label every time, even if the food was safe in the past. And two foods that seem the same might also own differences in how they’re made.

*Coconut

The FDA lists coconut as a tree nut.

In fact, coconut is a seed of a drupaceous fruit. Most people allergic to tree nuts can safely eat coconut. Coconut allergy is reasonably rare. If you are allergic to tree nuts, talk to your allergist before adding coconut to or eliminating coconut from your diet.

What Else Should I Know?

If you discover out you own a nut or peanut allergy, don’t be bashful about it. It’s significant to tell your friends, family, coaches, and teachers at school. The more people who know, the better off you are because they can assist you stay away from the nut that causes you problems.

Telling the server in a restaurant is also really significant because he or she can steer you away from dishes that contain nuts.

Likewise, a coach or teacher would be capable to select snacks for the group that don’t contain nuts.

It’s grand to own people love your parents, who can assist you avoid nuts, but you’ll also desire to start learning how to avoid them on your own.

What Else Should I Know?

Here are other things to remember:

  1. Watch for cross-contamination that can happen on kitchen surfaces and utensils — everything from knives and cutting boards to the toaster.

    Make certain the knife another family member used to make peanut butter sandwiches is not used to butter your bread and that nut breads are not toasted in the same toaster you use.

  2. Be certain your school knows about your allergy and has an action plan in put for you.
  3. Tell everyone who handles the food you eat, from relatives to restaurant waitstaff, that you own a nut allergy. If the manager, chef, or owner of a restaurant is uncomfortable about your request for peanut- or nut-free food preparation, don’t eat there.
  4. Make school lunches and snacks at home where you can control the preparation.
  5. Avoid cooked foods you didn’t make yourself — anything with an unknown list of ingredients.
  6. Keep save medicine (including epinephrine) on handat every times — not in your locker, but in a pocket, purse, or bookbag that’s always with you.

Living with a food allergy can seem hard at times.

What causes cashew nut allergy

But as more and more people are diagnosed with food allergies, businesses and restaurants are increasingly aware of the risks they face.

If friends you’re visiting or eating lunch with don’t know about your food allergy, tell them in plenty of time to make some simple preparations (such as not sharing your drink after eating that peanut butter sandwich!). Chances are, they’ll understand. As your friends, they probably hope you’ll be as considerate when it comes to taking care of them!

Tree Nut Allergy

Tree nut allergy is the second most common allergy in infants and young children.

What causes cashew nut allergy

Approximately % of American children own a tree nut allergy. Tree nuts are a common allergen reported to cause fatal and near-fatal allergic reactions.

Tree nut allergy is generally life-long once acquired. Approximately 9% of children allergic to tree nuts may outgrow their allergy.

Children with a tree nut allergy must avoid that tree nut and every products containing that type of tree nut. Children with a tree nut allergy also must avoid anything containing traces of ingredients containing that tree nut.

There is a potential of tree nut products having cross-contact other tree nuts and with peanuts. For this reason, your child’s doctor may advise you to avoid every tree nuts and peanuts.

What Will the Doctor Do?

If your doctor thinks you might own a nut or peanut allergy, he or she will probably send you to see a doctor who specializes in allergies. The (allergy specialist) will enquire you about past reactions and how endless it takes between eating the nut or peanut and getting the symptoms, such as hives.

The allergist may also enquire whether anyone else in your family has allergies or other allergy conditions, such as eczema or asthma.

Researchers aren’t certain why some people own food allergies and others don’t, but they sometimes run in families.

The allergist may also desire to do a skin test. This is a way of seeing how your body reacts to a extremely little quantity of the nut that is giving you trouble. The allergist will use a liquid extract of the nut that seems to be causing you symptoms.

During skin testing, a little scratch on your skin is made (it will be a quick pinch, but there are no needles!). That’s how just a little of the liquid nut gets into your skin. If you get a reddish, itchy, raised spot, it shows that you may be allergic to that food or substance.

Skin tests are the best test for food allergies, but if more information is needed, the doctor may also order a blood test.

At the lab, the blood will be mixed with some of the food or substance you may be allergic to and checked for antibodies.

It’s significant to remember that even though the doctor tests for food allergies by carefully exposing you to a extremely little quantity of the food, you should not attempt this at home! The only put for an allergy test is at the allergist’s office, where they are specially trained and could give you medicine correct away if you had a reaction.

What Are Peanut and Tree Nut Allergies?

Peanuts are among the most common allergy-causing foods, and they often discover their way into things you wouldn’t expect.

Take chili, for example: It may be thickened with ground peanuts.

Peanuts aren’t actually a true nut; they’re a legume (in the same family as peas and lentils). But the proteins in peanuts are similar in structure to those in tree nuts. For this reason, people who are allergic to peanuts can also be allergic to tree nuts, such as almonds, Brazil nuts, walnuts, hazelnuts, macadamia nuts, pistachios, pecans, and cashews.

Sometimes people outgrow some food allergies over time (like milk, egg, soy, and wheat allergies), but peanut and tree nut allergies are lifelong in numerous people.

What Happens With a Tree Nut or Peanut Allergy?

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 extremely hard to fight off the invader. This causes an allergic reaction.

How to Read a Label for Tree Nuts

Always read the entire ingredient label to glance for the names of the tree nut(s) you need to avoid. Tree nut ingredients may be within the list of the ingredients. Or tree nuts could be listed in a “Contains” statement beneath the list of ingredients. Examples are «Contains Walnut» or «Contains Almond».

This is required by the federal Food Allergen Labeling and Consumer Protection Act (FALCPA). Study more about the U.S. food allergen labeling law.

FALCPA requires that every packaged foods regulated by the FDA must list the common names of tree nuts clearly on the ingredient label if it contains tree nuts. Advisory statements such as “may contain hazelnuts” or “made in a facility with tree nuts” are voluntary. Advisory statements are not required by any federal labeling law.

Discuss with your doctor if you may eat products with these labels or if you should avoid them.

Did you know that marzipan, mortadella and  mandelonas every contain tree nuts? The FDA food allergen label law requires foods to state if they contain a top 8 allergen such as tree nuts. But, there are numerous foods and products that are not covered by the law, so it is still significant to know how to read a label for tree nut ingredients. Products exempt from plain English labeling rules: (1) Foods that are not regulated by the FDA.

(2) Cosmetics and personal care items. (3) Prescription and over-the-counter medications. (4) Toys, crafts and pet food.

How Is a Tree Nut or Peanut Allergy Treated?

There is no special medicine for nut or peanut allergies and numerous 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. (Sometimes these foods don’t even taste nutty! Would you believe chili sometimes contains nuts to assist make it thicker?)

Staying safe means reading food labels and paying attention to what they tell 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 home if someone spreads peanut butter on a sandwich and dips that same knife into the jar of jelly.

After checking the ingredients list, glance on the label for phrases love these:

  1. "may contain tree nuts"
  2. "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:

  1. cookies and baked goods
  2. Asian and African foods
  3. ice cream
  4. candy
  5. sauces (nuts may be used to thicken dishes)

Talk to your allergist about how to stay safe in the school cafeteria.

Also enquire about how you should handle other peanut encounters, love at restaurants or stadiums where people are opening peanut shells. People with nut allergies generally won’t own a reaction if they breathe in little particles. That’s because the food generally has to be eaten to cause a reaction.

What Are the Signs & Symptoms of a Nut Allergy?

When someone with a peanut or tree nut allergy has something with nuts in it, the body releases chemicals love .

This can cause symptoms such as:

It every depends on the person — and sometimes the same person can react differently at diverse times.

What Happens With a Tree Nut or Peanut Allergy?

When someone has a nut allergy, the body’s immune system, which normally fights infections, 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 extremely hard to fight off the invader. This causes an allergic reaction.

Even a little quantity of peanut or tree nut protein can set off a reaction. But allergic reactions from breathing in little particles of nuts or peanuts are rare.

That’s because the food generally needs to be eaten to cause a reaction. Most foods with peanuts in them don’t permit enough of the protein to escape into the air to cause a reaction. And just the smell of foods containing peanuts won’t cause one because the scent doesn’t contain the protein.

Some Unexpected Sources of Tree Nuts

Allergens are not always present in these food and products, but you can’t be too careful.

Remember to read food labels and enquire questions about ingredients before eating a food that you own not prepared yourself.

Tree nut proteins can be found in some surprising places, such as cereals, crackers, cookies, candy, chocolates, energy bars, flavored coffee, frozen desserts, marinades, barbeque sauces and some freezing cuts, such as mortadella.

Ice cream parlors, bakeries and certain restaurants (e.g., Chinese, African, Indian, Thai and Vietnamese) are considered high risk for people with tree nut allergy. Even if you order a tree nut-free dish, there is high risk of cross-contact.

Tree nut oils, such as walnut and almond, are sometimes used in lotions, hair care products and soaps.

Some alcoholic beverages may contain nut flavoring, so consider avoiding these as well.

Because these beverages are not federally regulated, you may need to call the manufacturer to determine the safety of ingredients such as natural flavoring.

Argan oil is derived from the nut of the argan tree and has rarely been reported to cause allergic reactions. While it is not a common food in the U.S., you will often discover it in Morocco.

People with cashew allergy may be at higher risk for allergy to pink peppercorn (known as Brazilian Pepper, Rose Pepper, Christmasberry and others).

This dried berry (Schinus, related to cashew) is used as a spice but is diverse from standard black pepper and fruits with “pepper” in their name (e.g., bell peppers, red peppers or chili peppers).

There is no evidence that coconut oil or shea nut oil and butter are allergenic. Coconut, the seed of a drupaceous fruit, has typically not been restricted in the diets of people with a tree nut allergy.

What causes cashew nut allergy

However, in October , the FDA began identifying coconut as a tree nut. Medical literature documents a little number of allergic reactions to coconut; most occurred in people who were not allergic to tree nuts.

What is tree nut allergy?

A nut allergy means the immune system mistakenly thinks the protein in nuts is harmful and commences an allergic reaction in a misguided attempt to protect the body from the ‘invader’. Nut allergy requires specialist medical diagnosis and treatment because allergic reactions can be serious and life-threatening.

Consultation with an Immunologist and an Accredited/Registered Dietitian who specialises in food allergy is recommended. It is not unusual to be allergic to several types of nuts, but it is also possible to be allergic to only one type of nut and be capable to eat other nuts without any problem.

The only treatment for food allergy is avoidance

If a person is allergic to a nut — or any other food — they must avoid eating it. Even tiny amounts can trigger a reaction that can be life-threatening. In the case of tree nuts, once the specific nut allergen(s) has been sure, it is possible to eat other types of nuts, but it’s recommended to consume them in their shell to avoid possible cross contamination.

How common is tree nut allergy?

Tree nuts include almonds, Brazil nuts, cashews, chestnuts, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts.

Australia has one of the highest rates of food allergy in the world59 and tree nut allergy is one of the most common food allergies, estimated to affect % of babies and young children60. Thankfully, allergy to macadamias is rare, estimated to cause less than 5% of every tree nut allergies26,61. While other food allergies — love allergies to eggs or milk – generally vanish by the time a kid starts school, nut allergies are more likely to persist into adulthood27, with only up to 20% of children outgrowing them.

A review of tree nut allergy conducted in 62 found prevalence rates varied around the world. On average they affect less than 2% of the population but can be up to 5%. Interestingly, individual tree nut allergy also varied by region.

What causes cashew nut allergy

For example, walnut allergy is most common in the UK, and hazelnut allergy is most common in Europe.

Nut allergy symptoms

The symptoms of food allergy generally happen immediately after the food is eaten and can include itching, swelling, hives, wheezing, shortness of breath, sweating, light headedness, nausea and bowel upset. In severe cases the allergic reaction can cause anaphylaxis (swelling of the throat that restricts the ability to breathe) and a sudden drop in blood pressure that can lead to organ failure.

If untreated this can be fatal.

People with anaphylactic reactions to nuts are advised to carry an injector pen with a dose of adrenalin (also called epinephrine) to assist them survive accidental nut ingestion, however immediate medical attention must be sought as well. They also need to be vigilant in reading food labels and enquire questions at restaurants and cafes to avoid nuts in food.

Peanuts are not tree nuts

Peanuts are ground nuts not tree nuts and are classified as legumes. However, peanuts are often bundled together with tree nuts in information about nut allergy as they cause similar reactions.

Peanut allergy is more common than tree nut allergy although both — including macadamia allergy — can cause severe reactions or anaphylaxis. Allergy to peanuts and tree nuts is increasing and no one is certain why. However, a large health nut study in Melbourne is looking for possible causes63.

Avoiding nuts

Common allergens such as nuts must be declared on food labels so people with nut allergy can avoid them. If the label is unclear, people with a nut allergy may need to check with the manufacturer. Families with a nut-allergic kid are advised to avoid nuts at home to minimise accidental exposure. Beware of nut allergies when preparing and serving nuts, or food containing nuts, to children you don’t know (such as when your children’s friends come to visit or if you host a party).

Nuts in schools and childcare

Individual schools and childcare centres with nut-allergic children can request every children avoid bringing nuts in their lunchbox to avoid the allergic kid accidentally eating nuts.

However, school nut bans are not recommended by state governments as they own not shown to be effective71. They can create a untrue sense of security causing children to be less vigilant. Schools need Allergy Aware policies with guidance for every students. Children allergic to nuts need to study the dangers of swapping food with friends, and their friends need to be taught not to do this in order to protect their allergic mate. The Allergy and Anaphylaxis Australia Be a Mate program is a excellent example of this.

Nuts during pregnancy

There is no evidence that women need to avoid eating nuts during pregnancy in an effort to reduce nut allergy unless they themselves own a nut allergy64.

Babies can eat nut pastes as first foods

A recent consensus of Australian allergy specialists has developed new guidelines for introducing nuts to infants. Nuts in the form of pastes or butters should be introduced around months of age when the baby is ready just love any other protein foods65.
