What are tree nuts allergies

The outlook for a tree nut allergy depends on two things: your age and your allergy severity. Adults diagnosed with a tree nut allergy should expect it to be lifelong.

For children, the outlook is a bit diverse. Some children will outgrow their food allergies, including an allergy to tree nuts. Unfortunately, compared with other allergies such as egg or milk, the number of children who outgrow their tree nut allergy is fairly low, around 10 percent, according to one . Children who are only mildly allergic to tree nuts (they don’t experience anaphylaxis when exposed to the allergen) own a better chance of outgrowing the allergy than children who own a extremely severe allergic reaction to tree nuts.

Thanks to increased societal awareness about food allergies, it’s now much easier for people with tree nut allergies to discover safe foods and communicate with others about their allergies.

Have you ever noticed the eye roll of a parent informed that their child’s classroom was nut-free and that they need to be mindful, sensitive, supportive and aware when bringing foods into the classroom? That parent obviously never had a kid with a food allergy. Although they are separate allergies, tree nut and peanut allergies can coexist. Both tree nut and peanut allergies are major precipitators of anaphylactic reactions. These allergies are no joke!

What Triggers An Allergic Reaction?

  • DIRECT CONTACT – The most common cause of an allergic reaction is eating or touching any food containing tree nuts or peanuts.
  • INDIRECT CONTACT (CROSS CONTAMINATION) – This can happen during food handling and processing.

    Processed foods run the risk of allergen contamination if prepared in factories that also prepare foods with tree nuts or peanuts. Eating at salad bars and ice cream parlors, purchasing unused bakery products, using store coffee grinders, and purchasing foods from bulk containers are additional potential sources of allergens. Remember that manufacturers that produce specific food products free from peanuts or any one nut may process other nuts on the same equipment.

  • INHALATION – Breathing in particles from tree nuts and peanuts can lead to allergic reactions.

    Peanut and tree nut flours as well as peanut and tree nut oils and extracts are common sources.

What Is A Tree Nut?

Tree nuts include: almonds, beechnuts, brazil nuts, butternuts, cashews, chestnuts, chinquapins, filberts (aka hazelnuts), gingkoes, hickory nuts, lichee nuts, macadamia nuts, pecans, pili nuts, pine nuts (aka pignolia, pignoli, pinoli, pinon), pistachios, shea nuts, pecans, and walnuts.

Although it is possible to be allergic to only one tree nut, most people with nut allergies are allergic to several or more nuts. Nut allergies are sometimes based on the protein pattern found.

Such pairs include almonds and hazelnuts, walnuts and pecans, cashews and pistachios. Being allergic to one of the nuts in such a pair puts one at risk for being allergic to the other nut. For example, a person allergic to pecans has a high likelihood of being allergic to walnuts. The risk of cross contact is high when multiple tree nuts are used during food production. For that reason, it may be recommended that a person who is allergic to any tree nut(s) avoid every tree nuts.

Is Coconut A Tree Nut?

Botanically, coconut is a fruit. Most people with tree nut allergies do not experience allergic reactions to coconut.

The FDA (US Food and Drug istration) classifies coconut as a nut for labelling purposes. If coconut is not part of your current diet, it is best to check with your allergist prior to eating coconut and coconut products.

Common Foods That May Contain Peanuts

peanut butter, peanut flour, peanut oil, beer nuts, nutmeats, mixed nuts, artificial nuts, goobers, beer nuts, nut pieces, artificial nuts, ground nuts, Cracker Jacks, monkey nuts, marzipan, enchilada sauce, peanut protein hydrolysate, egg rolls, salad garnishes, baking mixes, baked products, breadings, sauces, kernels, goober nuts, goober peas, arachis oil, arachide, mandelonas, valencias, cultural foods

Common Foods That May Contain Tree Nuts

nut butters, nut flour, baklava, pesto, pralines, marzipan, nut liquors, nougat, nut flours, baking mixes, macaroons, mixed nuts, nut pieces, marinades, salad dressings, Nutella, granola bars, trail mixes, cereals, fudge, baked items, ice cream, candy bars, cookies, crackers, sauces, lunchmeat, energy bars, caponata, salad garnishes, breadings, almond extract, walnut extract, wintergreen extract; nut flavorings, cultural foods

Allergic Reactions

Signs of anaphylaxis include swelling, rapid pulse, wheezing, difficulty breathing, rash, rapid pulse, lightheadedness/dizziness, and loss of consciousness.

Anaphylaxis is a medical emergency. Epinephrine injection should be given immediately and 911 called for emergency care.

In addition to potential life-threatening anaphylaxis, less severe allergic reactions to peanuts and tree nuts include itchy skin, itchy eyes, itchy ears, rashes, conjunctivitis, hives, swelling, eczema, runny nose, sneezing, tingling, dryness in the mouth and throat areas, diarrhea, stomach cramps, abdominal pain, and nausea. Medical advice and attention is indicated for anyone with any symptoms to guarantee appropriate monitoring should symptoms progress.

Are Peanuts Tree Nuts?

Peanuts are technically legumes and do not drop under the tree nut category.

Because peanuts grow underground, they are not considered in the same class as tree nuts. Although possible, having an allergy to peanuts does not necessarily mean a higher incidence of an allergy to legumes (peas, beans, lentils, soybeans). However, there is a higher likelihood of allergic reactions to lupins (aka lupines) in individuals who experience peanut allergies. Sometimes a peanut allergy is an indicator for the need to also avoid seeds such as sunflower, flax, poppy, pumpkin, and sesame.

Always check with your allergist with any allergy concerns. Peanut and tree nut allergies can coexist or can manifest as separate allergies. It is significant to hold in mind that tree nuts and peanuts are often found together in nut mixes and during food processing.

Risk Factors

Although there are numerous unknowns as to why some people develop allergies and others do not, the following risk factors are common.

Risk Factors

Although there are numerous unknowns as to why some people develop allergies and others do not, the following risk factors are common.

  • GENETICS – The risk of any food allergy increases if family members own food allergies.
  • HISTORY – A food allergy can resurface even after an allergy is believed to own been outgrown.
  • swelling of the face, around the eyes, lips, tongue and roof of the mouth (angioedema)
  • an itchy sensation inside the mouth, throat or ears
  • KNOWN ALLERGIES – Having another type of allergy (such as to mold or pollen) or being allergic to any food increases the likelihood of developing a food allergy to another food.
  • AGE – Tree nut and peanut allergies happen most commonly in infants, toddlers, and school age children.

    However, people at any age can develop allergic reactions to foods. Sometimes children outgrow food allergies as their digestive systems mature.

  • ECZEMA – A link is sometimes seen between the skin condition known as atopic dermatitis (eczema) and food allergies.
  • a raised itchy red rash (urticaria, or «hives»)
  • vomiting

Is Nutmeg A Tree Nut?

Despite its name, nutmeg is not a tree nut. Nutmeg is a spice derived from the nutmeg tree. Nutmeg is technically a seed. If you own a seed allergy, nutmeg should be avoided. Similarly, if you notice an allergic reaction associated with eating nutmeg, you numerous own an allergy to seeds.

What To Do When Choosing Foods

Always read food labels.

Manufacturing practices and ingredients can change at any time and without warning or change in taste or appearance of the food or drink item.

The best way to avoid triggering an allergic reaction is to avoid the allergen!

As common food allergens, tree nuts and peanuts are required by the FDA (US Food and Drug istration ) to be listed on food labels. The Food Allergy Labeling and Consumer Protection Act (FALCPA) requires that manufacturers clearly indicate the specific nut(s) a product contains. If a label mentions a specific nut such as “contains almonds,” it is significant to remember that another nut such as walnuts may be used in the same factory for other foods.

Mention of the presence of any tree nuts or peanuts used on the same production lines or in the same factory is not required. Numerous companies voluntarily indicate possible tree nut and peanut cross contamination as precautionary allergens on their labels. Examples of such voluntary and unregulated labeling include “ may contain peanuts,” “may contain traces of peanuts,” “manufactured in a facility that also processes nuts,” and “manufactured in a facility that also processes peanuts.” Unless produced in a dedicated nut free or peanut free facility, products that do not list possible cross contaminants should be avoided by persons who own tree nut or peanut allergies.

Sometimes prepackaged foods that include any of the eight major allergens (tree nuts, peanuts, milk, eggs, fish, crustacean shellfish, wheat, soybeans) are incorrectly labelled in the manufacturing process. The FDA recalls such products. There is no such worry for Enjoy Life Foods products as the majority of their products are manufactured in the bakery they opened in Jeffersonville, IN in 2016 – North America’s largest dedicated nut-free, allergy-friendly, and certified gluten-free bakery.

Not every products are made in Jeffersonville, but they are always manufactured in a facility with validated allergen cleaning and testing processes.

Alcoholic beverages are not covered under FALCPA. If natural flavors or botanicals are listed as ingredients, you can contact the manufacturer to enquire if those ingredients include nuts or nut flavors.

The following message that I received from a thoughtful and loving mom whose kid has multiple food allergies summarizes this blog well:

“As the parent of a kid with multiple food allergies, I am always looking for products with clear, simple ingredient lists.

I also really appreciate clear alerts on packages when they own changed their ingredient lists in any way. Nut allergies can be challenging in bakeries because nut extracts are added to so numerous vanilla and chocolate cookies and cakes. When making similar items at home, I attempt to extremely explicitly point out why our home version is okay and the bakery versions are NOT. Being capable to own Enjoy Life products in my bag in a pinch when we’re out also helps take the pressure and anxiety out of making an inadvertent error in the bakery.”

Allergic reactions to tree nuts

An allergic reaction generally happens within minutes after being exposed to an allergen, but sometimes it can take put several hours after exposure.

Anaphylaxis is the most serious type of allergic reaction.

Symptoms of anaphylaxis generally include two or more of the following body systems:

  1. 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
  2. Gastrointestinal (stomach): nausea, pain/cramps, vomiting, diarrhea
  3. Cardiovascular (heart): paler than normal skin colour/blue colour, feeble pulse, passing out, dizziness or lightheadedness, shock
  4. Skin: hives, swelling (face, lips, tongue), itching, warmth, redness
  5. Other:anxiety, sense of doom (the feeling that something bad is about to happen), headache, uterine cramps, metallic taste

If you own an allergy to tree nuts, hold an epinephrine auto-injector (e.g., EpiPen®) with you at every times.

Epinephrine is the first-line treatment for severe allergic reactions (anaphylaxis).

Note: The above lists are not finish and may change.

Emerging Allergen Reporting Tool

If your kid has had a reaction in the final 12 months to a food other than a priority allergen, participate in an significant research survey. Your participation will assist researchers, and advocacy groups love ours, better understand emerging allergens.

Study more and take the survey

Quick facts

  1. Priority food allergens are the foods that cause the majority of allergic reactions.

  2. Tree nuts considered as priority allergens include almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts (pignolias), pistachio nuts and walnuts.

    What are tree nuts allergies

  3. Some people with a tree nut allergy may be allergic to more than one type of tree nut.
  4. Peanuts are part of the legume family and are not considered a tree nut.
  5. Tree nuts are considered priority allergens by Health Canada.
  6. People who are allergic to tree nuts generally avoid every nuts and peanuts because of the risk of cross contamination.

Remember

  1. Coconut and nutmeg are not considered tree nuts for the purposes of food allergen labelling in Canada and are not usually restricted from the diet of someone allergic to tree nuts.

  2. A coconut is a seed of a fruit and nutmeg is obtained from the seeds of a tropical tree.
  3. However, some people allergic to tree nuts own also reacted to coconut and nutmeg. Consult your allergist before trying coconut- or nutmeg-containing products.

Be Allergy-Aware: How to avoid tree nuts

  • Read ingredient labels every time you purchase or eat a product. If the label indicates that a product “Contains” or “may contain” tree nut, do not eat it. If you do not recognize an ingredient, if there is no ingredient list available, or if you don’t understand the language written on the packaging, avoid the product.

  • According to Health Canada:
    1. If a tree nut is part of the ingredients, the specific tree nut(s) must be declared by their common name (almond, Brazil nut, etc.) in the list of ingredients or in a separate “contains” statement immediately following the list of ingredients.
  • Do The Triple Check and read the label:
    1. Once when you get home and put it away.
    2. Always carry your epinephrine auto-injector. It’s recommend that if you do not own your auto-injector with you, that you do not eat.
    3. Be careful when buying imported products, since labelling rules differ from country to country.
    4. Check with manufacturers directly if you are not certain if a product is safe for you.

    5. Again before you serve or eat the product.
    6. Once at the store before buying it.
    7. Watch for cross-contamination, which is when a little quantity of a food allergen (e.g., almond) gets into another food accidentally, or when it’s present in saliva, on a surface, or on an object. This little quantity of an allergen could cause an allergic reaction.

    What is a tree nut allergy?

    A tree nut allergy is one of the most common food allergies in both adults and children. Allergic reactions to tree nuts can range from mild (minor itching, watery eyes, and a scratchy throat) to life-threatening. You may be allergic to just one type of tree nut, or you could be allergic to several. Examples of tree nuts include:

    1. walnuts
    2. pecans
    3. pine nuts
    4. hazelnuts
    5. almonds
    6. lychee nuts

    Being allergic to one type increases your risk for being allergic to others.

    Until your allergies are tested by your allergist-immunologist (a doctor who specializes in treating allergies and the immune system), you may be asked to avoid every tree nuts.


    What are the symptoms of a tree nut allergy?

    If you’re allergic to tree nuts and exposed to them, you may develop symptoms of an allergic reaction. In some cases, these symptoms will appear within minutes and be severe. In other cases, it may take 30 minutes to a few hours before symptoms begin.

    Symptoms of a tree nut allergy may include:

    Anaphylaxis is rare, but it’s the most severe form of allergic response.

    In the case of anaphylaxis, a person with an allergy will typically start experiencing symptoms within 5 to 30 minutes of exposure to the tree nut. Symptoms of anaphylaxis include:

    1. wheezing
    2. passing out
    3. vomiting
    4. trouble swallowing
    5. swollen throat
    6. a red rash with hives or welts

    Peanut, shellfish, and tree nut allergies are among the most common causes of anaphylaxis. People with a severe tree nut allergy should always be prepared to reply to an allergic reaction. You should always hold an epinephrine auto-injector with you. Common brands of auto-injectors include EpiPen, Adrenaclick, and Auvi-Q.


    What foods should I avoid if I own a tree nut allergy?

    Tree nut allergies cannot be cured.

    So, the best way to avoid a tree nut allergy reaction is to avoid them. Strict avoidance of nuts and products that might contain nuts should protect you against an allergic reaction. Numerous doctors will recommend that people, especially children, with a diagnosed allergy to one tree nut avoid every tree nuts because of the potential for an allergy to those as well.

    The most widely consumed tree nuts include:

    1. cashews
    2. macadamia nuts
    3. pistachios
    4. pecans
    5. hazelnuts/filberts
    6. almonds
    7. Brazil nuts
    8. pine nuts
    9. walnuts

    Nut butters, nut oils, and natural nut extracts are also off limits for people with tree nut allergies.

    In the United States, food manufacturers are required to list if their foods may contain allergens, including tree nuts.

    You should also read ingredient lists on food labels to be certain the food is allergen-free. Sometimes foods may come in contact with tree nuts during the manufacturing process. Food packaging also often lists that potential hazard.

    However, don’t assume that a safe food will always be safe. Food manufacturers change their formulas regularly, and they may start adding tree nuts without notice. That’s why it’s brilliant to read labels every time you pick up a food.

    You can never be too careful, especially if you own a severe allergy to tree nuts.

    Hidden sources of tree nuts

    Allergens can hide in products you may not suspect despite labeling guidelines imposed by the Food and Drug istration (FDA). Tree nut proteins may be found in:

    1. desserts: candy, chocolates, ice creams, and frozen yogurts
    2. beverages: flavored coffees, alcoholic beverages, and liqueurs
    3. perishable goods: freezing cuts, cheeses, marinades, and condiments
    4. dry goods: cookies, cereals, crackers, protein or energy bars, and breakfast bars
    5. personal hygiene products: lotions, shampoos, perfumes, and soaps

    Some restaurants may also use tree nuts in their recipes without labeling the food in the dish’s description.

    Communicating with your server is imperative when you’re dining in a restaurant.


    How are tree nut allergies diagnosed?

    Tree nut allergies can be life-threatening. That’s why it’s so significant to own a definitive diagnosis from an allergist. To diagnose your allergies, your allergist may conduct a skin prick test. During this test, your skin will be exposed to a variety of allergens. If you’re allergic to one of the allergens, your skin will react and swell or turn red.

    Your doctor may also recommend blood tests depending on your age and other medical conditions you have.

    If the results of your tests are inconclusive, your doctor may request a food challenge. For this test, you will be exposed to the allergen (a specific food item) in increasing doses over several hours.

    What are tree nuts allergies

    Your doctor will supervise this test in case there is an allergic reaction. Emergency medication and services should be at hand during the test.


    What are risk factors for tree nut allergies?

    It’s significant to know the risk factors associated with tree nut allergies. Here are some common risk factors.

    Peanut allergy

    Peanuts are not tree nuts, they are legumes, but being allergic to peanuts increases your risk for a tree nut allergy. In fact, 25 to 40 percent of people who are allergic to peanuts are also allergic to tree nuts, according to the American College of Allergy, Asthma & Immunology.

    Other tree nut allergies

    If you are allergic to one type of tree nut, you may be allergic to others.

    Your immunologist may select to conduct a finish allergy screening test to figure out every your allergies.

    Family history

    If a parent or sibling has a tree nut allergy, other children and siblings are at an increased risk. A doctor can provide guidance on testing for allergies in families.
