Where do peanut allergies come from?

It’s crucial to understand what causes peanut allergy to combat it effectively.

It is an immune response triggered by the proteins found in peanuts. It occurs when the immune system mistakenly perceives peanut protein as harmful. (1)

Any direct or indirect contact with peanuts causes the immune system to release specific chemicals into the bloodstream that cause the symptoms I will mention below.

When someone with a peanut allergy eats peanuts or any peanut products, their immune system mistakenly identifies the proteins as harmful invaders and launches an attack.

The most common symptoms of peanut allergy can range from mild to severe. These symptoms may include: (2)

  • itching or tingling, especially in the mouth
  • hives
  • face, eyes, tongue, lips, or throat swelling
  • difficulty breathing
  • wheezing
  • nasal congestion
  • abdominal pain
  • nausea
  • vomiting
  • diarrhea
  • dizziness
  • fainting
  • in extreme cases, anaphylaxis – a potentially life-threatening reaction

It’s worth noting that even a small amount of peanuts or peanut residue can trigger an allergic reaction in susceptible individuals.

While anyone can develop a peanut allergy, certain risk factors make some individuals more vulnerable.

Allergy risk factors for people

These factors include a family history of food allergies, a medical history of other allergies or asthma, and other allergic conditions like eczema. (3)

It’s also important to note that they can develop at any age, and their severity can vary from person to person.

How to identify if you have a peanut allergy

Consult an allergist who can perform specific tests to identify if you or a loved one has a peanut allergy.

These tests may involve a skin prick test or blood test to detect any presence of specific antibodies. By identifying the allergy early on, you can take proactive measures to prevent exposure and minimize the risk of severe allergic reactions.

Understanding peanut allergy’s underlying mechanisms and risk factors sets the stage for implementing preventive measures.

Research has shown that individuals with a family history of allergies, such as asthma, eczema, or other food allergies, are more likely to develop a peanut allergy. (4)

Moreover, it is essential to recognize that peanut allergies differ from other food allergies. So they can persist throughout a person’s lifetime.

While some children will outgrow specific allergies, such as milk or egg, peanut allergies are often lifelong conditions. Recent findings have shown that approximately 20% of children may be able to outgrow a peanut allergy by adulthood. (5)

Are peanut and tree nut allergies considered the same?

Peanuts are a legume and not technically a nut. While they share some similarities to tree nuts, such as proteins, most allergists classify peanuts and tree nuts as two different types of allergies.

Just because someone is allergic to peanuts does not mean they are necessarily also allergic to tree nuts.

Many people with peanut allergies will test high on various protein tests, even for the different types of tree nuts – but that does not mean they are allergic to all sorts of tree nuts.

Tree nuts include almonds, hazelnuts, walnuts, cashews, pine nuts, and pistachios.

Each type of tree nut poses a risk of potential allergies. Consumers should consult their doctor or allergist if they believe they may be allergic to any food.

How to prevent peanut allergy

Regular consumption is crucial to allergy prevention once you’ve safely consumed foods containing peanuts.

Best guidelines recommend that infants, especially those at the highest risk, consume about two grams of peanut protein (equivalent to two teaspoons of peanut butter) thrice weekly. (6)

Individuals and their families can work with healthcare professionals to implement adequate preventive measures by being aware of the symptoms, signs, and risk factors associated with peanut allergies.

How to prevent peanut allergy in pregnancy and babies

Researchers advise mothers to breastfeed for at least the first six months of life and include peanuts in the diet from four to six months. (7)

Overall, the data found that introducing peanut products into all infant diets by six months could reduce them in the general population by up to 77%. (8)

Monitoring for even mild reactions in trace amounts of allergens like macadamia nuts is essential, as they can escalate to more severe symptoms such as shortness of breath and anaphylactic reactions.

Why are so many children allergic to these nuts?

Peanut allergies are among children’s most common food allergies, affecting many youngsters worldwide.

The exact cause of why so many kids are allergic to peanuts is still unknown, but several factors may be responsible for this trend.

Firstly, peanut sensitization can often be hereditary – parents with peanut allergy may pass it down to their children before exposure to peanuts.

In addition, early introduction of peanuts in infancy or other allergens like eggs or milk may lead to a hypersensitivity syndrome, making the individual more likely to have adverse reactions when presented with these foods later on.

Modern-day lifestyle practices such as inadequate breastfeeding or insufficient diet diversity can also increase susceptibility towards food allergies, including peanut allergies.

For instance, the prolonged use of infant formula containing nuts and eggs instead of exclusively breastfeeding an infant could increase vulnerability to nuts and eggs later on.

Furthermore, children in urban areas lack access to fresh and local products that their peers elsewhere have, leading them to eat processed food more frequently than healthy whole foods, leading to imbalances that can impair immune health and possibly lead to allergies.

How to mitigate the risk of peanut allergies in daily life

#1 Early introduction of peanuts

Recent research has shown that introducing peanuts to infants early, between 4–6 months, can help reduce the risk of developing a peanut allergy. (9)

It was previously believed that avoiding peanuts altogether in infancy was the best approach. However, studies have found that gradual exposure can promote tolerance. (10)

However, it’s crucial to consult with a pediatrician or allergist before introducing potentially allergenic foods to your baby.

#2 Breastfeeding

Breastfeeding can play a significant role in reducing this risk.

Cooking for allergies

Studies have suggested that nursing mothers who consume peanuts and other allergenic foods during pregnancy and while breastfeeding may help their babies develop tolerance to these foods. (11)

However, if you have a family history or your baby has shown signs of a food allergy, it’s crucial to consult a healthcare professional before making dietary changes.

#3 Reading labels and avoidance

A significant aspect of preventing peanut allergies is strictly avoiding peanuts and peanut-containing products if you or your child has already been diagnosed with an allergy.

Always read food labels carefully and avoid products containing peanuts or traces of peanuts.

Reading labels and avoidance

It’s crucial to carefully read the ingredient label on salad dressings, especially if you have allergies to tree nuts, as consuming them without knowing can lead to severe reactions that may affect your blood pressure and overall health.

It’s also essential to educate yourself and your family about hidden sources of peanuts, such as certain sauces, dressings, and baked goods.

#4 Creating an allergy-free environment

A critical step to prevent them is creating an allergy-free environment, especially for individuals with severe allergies.

By implementing these prevention methods, individuals with peanut allergies can significantly reduce their risk of experiencing severe allergic reactions.

This strategy includes informing schools, childcare providers, and family members about the allergy. Request their support in avoiding exposure to peanuts, ensuring everyone is on the same page.

Regular cleaning and sanitizing of surfaces can remove traces of peanuts, reducing the risk of unintentional exposure through cross-contamination.

This process is critical in shared spaces like kitchens, classrooms, and daycare facilities.

By fostering open lines of communication, it becomes easier to establish guidelines and protocols that prioritize the well-being of individuals with a peanut allergy.

What is the best treatment for an allergic reaction?

Avoiding peanuts and peanut products is the only way to prevent an allergic reaction.

However, peanuts are commonplace, and even with your best efforts, you’ll likely run into peanuts at some point.

An allergic reaction is a response from the body’s immune system to something it considers a foreign invader, like peanuts.

Peanut allergies can cause anaphylaxis, a severe reaction starting with the same symptoms as a less severe reaction before quickly worsening, leading to difficulty breathing, lightheadedness, and even loss of consciousness.

If you don’t get treatment right away, anaphylaxis can be life-threatening.

In response to this allergic reaction, doctors usually prescribe an epinephrine auto-injector for those with severe food allergies.

This prescription medication comes in a portable container you can easily carry in an emergency box. To use it, you insert the device into your thigh and press down on the top until it clicks to release the medication into your bloodstream.

Final notes about what causes peanut allergy and how to prevent it

In conclusion, understanding what causes peanut allergy and implementing preventative measures is crucial in safeguarding the health of ourselves and our loved ones.

By identifying symptoms, risk factors, and following effective prevention methods, we can significantly reduce the risk of developing peanut allergies.

Creating an allergy-free environment adds another layer of protection. Remember, acting today can make a lasting impact on our well-being tomorrow.

As the Dutch humanist scholar Desiderius Erasmus said,

“Prevention is better than cure.”

So, let’s take charge of our health and make peanut allergies a thing of the past.
