Peanut & Peanut Butter Allergy: Symptoms, Triggers & Awareness

Peanut allergy is one of the more common food allergies and often appears in childhood. Some individuals outgrow it over time, while others continue to react into adulthood. Reactions can vary from mild symptoms to severe allergic responses.

Relevance in Canada, Food Safety & Daily Life

Food allergies are relevant in schools, workplaces, restaurants, sports, and travel. Canadian families often encounter peanuts in packaged foods, shared snacks, and baking. Food allergy awareness helps peers and adults support safe environments.

Scenario (Mild & Realistic)

At lunch, a student noticed a snack label listed peanuts and chose a different food. Their friend mentioned having a peanut allergy and appreciated that ingredients were checked first.

What Causes Peanut Allergy?

Food allergies involve the immune system reacting to a protein in food as if it were harmful. In peanut allergy, immune responses may involve antibodies that trigger symptoms in areas such as the skin, breathing passages, or digestive tract.

Symptoms of Peanut Allergy

Skin & Eyes

• Itchy skin

• Hives or welts

• Redness or warmth

• Itchy or watery eyes

Breathing & Nose

Some symptoms resemble those of asthma or seasonal allergies, including:

• Coughing

• Wheezing

• Sneezing

• Runny or itchy nose

• Sensation of tightness in the throat

Digestive System

Food allergies can also affect digestion, including:

• Nausea

• Vomiting

• Cramping

• Diarrhea

• Itchiness or redness around the mouth

Severe Allergic Reactions (Anaphylaxis)

A small number of individuals with peanut allergy may experience anaphylaxis, a severe allergic reaction involving multiple body systems. Symptoms can include:

• Difficulty breathing

• Dizziness or faintness

• Rapid changes in pulse

• Sudden drop in blood pressure

• Widespread hives or swelling

Anaphylaxis is considered a medical emergency and requires rapid intervention from trained responders.

Food Exposure & Label Awareness

Peanut ingredients can be found in:

• Peanut butter

• Baked goods (cookies, pastries, bars)

• Ice cream and desserts

• Chocolates and candies

• Sauces and international cuisine

• Asking about ingredients when eating out

• Avoiding foods with unclear contents

• Planning for school and social events

Families, schools, activity groups, and workplaces often collaborate on food allergy awareness to support inclusive environments.
