What are cashew allergies
Most food allergies affect younger children under the age of 3.
Most children who own food allergies to milk, eggs, soya and wheat in early life will grow out of it by the time they start school.
Peanut and tree nut allergies are generally more endless lasting.
Food allergies that develop during adulthood, or persist into adulthood, are likely to be lifelong allergies.
For reasons that are unclear, rates of food allergies own risen sharply in the final 20 years.
However, deaths from anaphylaxis-related food reactions are now rare.
What causes food allergies?
Food allergies happen when the immune system – the body’s defence against infection – mistakenly treats proteins found in food as a threat.
As a result, a number of chemicals are released.
It’s these chemicals that cause the symptoms of an allergic reaction.
Almost any food can cause an allergic reaction, but there are certain foods that are responsible for most food allergies.
Foods that most commonly cause an allergic reaction are:
- tree nuts
- some fruit and vegetables
Most children that own a food allergy will own experienced eczema during infancy.
The worse the child’s eczema and the earlier it started, the more likely they are to own a food allergy.
It’s still unknown why people develop allergies to food, although they often own other allergic conditions, such as asthma, hay fever and eczema.
Read more information about the causes and risk factors for food allergies.
In the most serious cases, a person has a severe allergic reaction (anaphylaxis), which can be life threatening.
Call if you ponder someone has the symptoms of anaphylaxis, such as:
- trouble swallowing or speaking
- breathing difficulties
- feeling dizzy or faint
Ask for an ambulance and tell the operator you ponder the person is having a severe allergic reaction.
Types of food allergies
Food allergies are divided into 3 types, depending on symptoms and when they occur.
- non-IgE-mediated food allergy – these allergic reactions aren’t caused by immunoglobulin E, but by other cells in the immune system. This type of allergy is often hard to diagnose as symptoms take much longer to develop (up to several hours).
- IgE-mediated food allergy – the most common type, triggered by the immune system producing an antibody called immunoglobulin E (IgE). Symptoms occur a few seconds or minutes after eating. There’s a greater risk of anaphylaxis with this type of allergy.
- mixed IgE and non-IgE-mediated food allergies – some people may experience symptoms from both types.
Read more information about the symptoms of a food allergy.
Oral allergy syndrome (pollen-food syndrome)
Some people experience itchiness in their mouth and throat, sometimes with mild swelling, immediately after eating unused fruit or vegetables.
This is known as oral allergy syndrome.
Oral allergy syndrome is caused by allergy antibodies mistaking certain proteins in unused fruits, nuts or vegetables for pollen.
Oral allergy syndrome generally doesn’t cause severe symptoms, and it’s possible to deactivate the allergens by thoroughly cooking any fruit and vegetables.
The Allergy UK website has more information.
When to seek medical advice
If you ponder you or your kid may own a food allergy, it’s extremely significant to enquire for a professional diagnosis from your GP. They can then refer you to an allergy clinic if appropriate.
Many parents mistakenly assume their child has a food allergy when their symptoms are actually caused by a completely different condition.
Commercial allergy testing kits are available, but using them isn’t recommended.
Numerous kits are based on unsound scientific principles. Even if they are dependable, you should own the results looked at by a health professional.
Read more about diagnosing food allergies.
The best way to prevent an allergic reaction is to identify the food that causes the allergy and avoid it.
Research is currently looking at ways to desensitise some food allergens, such as peanuts and milk, but this is not an established treatment in the NHS.
Read more about identifying foods that cause allergies (allergens).
Avoid making any radical changes, such as cutting out dairy products, to your or your child’s diet without first talking to your GP. For some foods, such as milk, you may need to speak to a dietitian before making any changes.
Antihistamines can assist relieve the symptoms of a mild or moderate allergic reaction. A higher dose of antihistamine is often needed to control acute allergic symptoms.
Adrenaline is an effective treatment for more severe allergic symptoms, such as anaphylaxis.
People with a food allergy are often given a device known as an auto-injector pen, which contains doses of adrenaline that can be used in emergencies.

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

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:
- "may contain tree nuts"
- "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:
- Asian and African foods
- cookies and baked goods
- ice cream
- 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.
Tree Nut Substitutions
It is extremely simple to replace nuts in a recipe. There are numerous seeds and seed products available including sunflower butter and pumpkin seed butter. Roasted chickpeas can replace nut snacks. Pretzels can substitute for pecans in pecan pie.
Learn more about NUT SUBSTITUTES.
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.
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.
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:
- throat tightness
- itchy, watery, or swollen eyes
- trouble breathing
- dizziness or fainting
- a drop in blood pressure
- anxiety or a feeling something bad is happening
Reactions to foods, love peanuts and tree nuts, can be diverse.
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 nuts and peanuts
There’s often confusion between peanuts and tree nuts.
Peanuts are legumes, not nuts; still, between 25 and 40 percent of individuals who are allergic to peanuts also react to at least one tree nut, according to studies.
Allergists generally advise people who are allergic to tree nuts also to avoid peanuts because of the risk of cross-contact and cross-contamination between tree nuts and peanuts in food processing facilities. If you or your kid is allergic to either peanuts or tree nuts, enquire your allergist whether you should avoid both products.
The prevalence of these allergies in children appears to be growing, according to a study that compared data from telephone surveys of 5, U.S.
households in , and In the survey, percent of respondents reported having a kid with an allergy to peanuts, tree nuts or both. In the survey, percent of subjects said they had a kid with one or both of these allergies; five years earlier, in , only percent of respondents reported having a kid with one or both of these allergies.
Allergies to tree nuts and peanuts are among the most common causes of anaphylaxis in the United States. An allergist will advise patients with these allergies to carry an auto-injector containing epinephrine (adrenaline), which is the only treatment for anaphylactic shock, and will teach the patient how to use it.
If a kid has the allergy, teachers and caregivers should be made aware of his or her condition as well.
People with tree nut allergies often wonder if they must also avoid coconut and nutmeg.
Coconut is not a botanical nut; it is classified as a fruit, even though the Food and Drug istration recognizes coconut as a tree nut. While allergic reactions to coconut own been documented, most people who are allergic to tree nuts can safely eat coconut. If you are allergic to tree nuts, talk to your allergist before adding coconut to your diet.
Nutmeg is a spice that is derived from seeds, not nuts.
It may be safely consumed by people with a tree nut allergy.

Oh, nuts! They certain can cause you trouble if you’re allergic to them — and a growing number of kids are these days.
So what helpful of nuts are we talking about? Peanuts, for one, though they aren’t truly a nut.

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.

As with most food allergies, the best way to avoid triggering an allergic reaction is to avoid eating the offending item.
People who are diagnosed with an allergy to a specific tree nut may be capable to tolerate other tree nuts, but allergists generally advise these patients to avoid every nuts. Tree nuts are often used as garnishes in salads, as an ingredient in Asian dishes, and as an ice cream topping. They may also be found in baking mixes, breading, sauces, desserts and baked goods.
Tree nuts are among the eight most common food allergens affecting adults and children, and are specifically mentioned in the Food Allergen Labeling and Consumer Protection Act (FALCPA) of This means that the presence of these items must be highlighted, in clear language, on ingredient lists.
Some companies may voluntarily include information that their food products that don’t contain nuts were manufactured in a facility that also processes nuts, though such a statement is not required by law. It is significant for people with tree nut allergies to read labels carefully.
Some alcoholic beverages may contain nuts or nut flavoring added in the distillation process. Most alcoholic beverages aren’t covered by the FALCPA requirements; if “natural flavors” or “botanicals” are cited as an ingredient, you may need to call the manufacturer to determine whether that indicates the presence of nuts or nut flavoring.
Tree nut oils, which may contain nut protein, can be found in lotions, hair care products and soaps; those allergic to tree nuts should avoid using these products.
Fortunately, allergists are specially trained to assist identify these hidden sources of tree nut allergens.

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.

Anaphylaxis is the most serious type of allergic reaction.
Symptoms of anaphylaxis generally include two or more of the following body systems:
- Cardiovascular (heart): paler than normal skin colour/blue colour, feeble pulse, passing out, dizziness or lightheadedness, shock
- Respiratory (breathing):coughing, wheezing, shortness of breath, chest pain/tightness, throat tightness, hoarse voice, nasal congestion or hay fever-like symptoms (runny itchy nose and watery eyes, sneezing), trouble swallowing
- Skin: hives, swelling (face, lips, tongue), itching, warmth, redness

A food allergy is when the body’s immune system reacts unusually to specific foods. Although allergic reactions are often mild, they can be extremely serious.
Symptoms of a food allergy can affect diverse areas of the body at the same time. Some common symptoms include:
- swelling of the face, around the eyes, lips, tongue and roof of the mouth (angioedema)
- an itchy sensation inside the mouth, throat or ears
- a raised itchy red rash (urticaria, or «hives»)
