Food Allergies and Intolerances
Some kids can't eat certain foods safely. Learn the Top 9 food allergens and how to read labels to keep yourself and your friends safe.
Materials and setup
- 5 food labels with allergen lists (Early Elem)
- paper, markers
- ingredients for the allergen-free recipe (Upper Elem)
- research resources (books or supervised internet)
Parent note
Pre-K and Kinder skipped — too nuanced. This lesson is critical safety education, especially if the child has classmates with allergies. Emphasize empathy — kids with allergies don't want pity, they want friends who take it seriously. Never pressure a child with an allergy to 'just try' the food. Upper Elem EpiPen content is educational; actual use requires medical training.
How this changes by age
Early elementary (ages 6–8)
Some kids can't eat certain foods safely. Learn the Top 9 food allergens and how to read labels to keep yourself and your friends safe.
Steps
- Introduce the difference: ALLERGY = immune system overreacts to a specific food, can be life-threatening. INTOLERANCE = body can't digest a food well, causes stomach trouble but not emergency.
- Meet the Top 9 food allergens (legally required to be labeled in the US): (1) milk, (2) eggs, (3) peanuts, (4) tree nuts (almonds, walnuts, cashews, pecans), (5) fish, (6) shellfish (shrimp, crab, lobster), (7) wheat, (8) soy, (9) sesame (added to the list in 2023).
- Learn to read for allergens: labels must clearly state 'Contains: ___' after the ingredient list. Practice on 5 products.
- Also check for 'May contain traces of ___' warnings — these flag cross-contamination risk.
- Research anaphylaxis: in severe allergy, throat can swell, breathing can stop, blood pressure can drop. Emergency treatment is epinephrine (EpiPen) injection + call 911. An EpiPen delivers a pre-measured dose into the thigh muscle. Kids with severe allergies carry one everywhere.
- Empathy mission: imagine you have a peanut allergy. List 10 foods you'd have to avoid or check carefully: PB&J, many cookies, granola bars, some cereals, Thai food, Chinese stir-fries, baked goods, many chocolates, ice cream with peanut flavor, some salad dressings.
- Friend-safety rules: (1) never share food with a friend who has an allergy without checking the label WITH them. (2) wash hands after eating allergens before touching shared surfaces. (3) know where your friend's EpiPen is and whom to call if they react. (4) take it seriously — it's not picky, it's life-or-death.
- Make a 'Friend Safety' poster with the 4 rules and the Top 9 allergens.
- Extension: research one food intolerance in detail — lactose intolerance. Why do some adults stop making lactase (the enzyme)? Different populations have different rates (lactose tolerance is more common in people of Northern European descent — an evolutionary response to dairying).
Learning objectives
- Distinguish food allergy from food intolerance
- Identify the Top 9 food allergens on any label
- Apply friend-safety rules when around someone with an allergy
Upper elementary (ages 8–10)
Dive into the immunology of allergies, compare celiac disease to other conditions, and design a safe recipe for a friend with dietary restrictions.
Steps
- Study allergy immunology: in a true food allergy, B cells mistake a food protein as a threat and produce IgE antibodies. When the food is eaten again, IgE triggers mast cells to release histamine, causing reaction (hives, swelling, breathing problems, anaphylaxis).
- Compare 3 conditions on a table:
- (1) TRUE ALLERGY (e.g., peanut allergy) — IgE mediated, fast (minutes), can be life-threatening. Treatment: strict avoidance + EpiPen.
- (2) CELIAC DISEASE — autoimmune reaction to gluten (wheat, barley, rye). Body attacks its own small intestine, damaging villi. Not an allergy (no IgE) but also not 'just intolerance'. Can cause long-term malabsorption, other autoimmune conditions. Treatment: strict lifetime gluten-free diet.
- (3) LACTOSE INTOLERANCE — missing lactase enzyme, so lactose (milk sugar) passes undigested to colon, ferments, causes bloating + gas + diarrhea. Not immune-mediated. Treatment: reduce dairy OR take lactase pills.
- Research how an EpiPen works mechanically: pre-filled spring-loaded auto-injector delivers 0.15 or 0.30 mg epinephrine into thigh muscle. Epinephrine reverses anaphylaxis by constricting blood vessels (raising blood pressure), opening airways, and stopping mast cell activation. Works in ~5 minutes.
- Research emerging treatments: oral immunotherapy (OIT) — gradually exposing kids to tiny increasing amounts of the allergen under medical supervision to train the immune system. Works for ~60-70% of kids with peanut allergy but requires months of daily dosing. Not a cure.
- Recipe design challenge: pick a dessert or meal. Make a version that is safe for someone with 3 dietary restrictions — say, celiac + dairy-free + nut-free. Identify substitutions: gluten-free flour (rice, almond, oat), dairy-free milk (oat, coconut, soy), no nuts.
- Cook your version. Photograph. Compare taste to the original. Rate 1-5.
- Research the economic side: dietary-restricted products cost 2-4x more than regular versions. Why? Smaller production runs, separate facilities to avoid cross-contamination, specialty ingredients. This is a real financial burden for families.
- Write a 2-page paper comparing the 3 conditions, explaining EpiPen pharmacology, and including your recipe with taste data.
- Extension: research food allergy diagnosis — skin-prick test, blood IgE test, oral food challenge. Each has different accuracy and risk. Which does a doctor use when?
Learning objectives
- Explain the IgE-mediated immunology of true food allergies
- Compare allergy, celiac disease, and lactose intolerance on mechanism and treatment
- Design and cook an allergen-free recipe with taste evaluation
Safety and evidence note
Read the full activity before beginning. An adult should supervise tools, heat, food, outdoor work, movement, and experiments as appropriate. Completion records that the activity was done; the child’s explanation, work sample, photo, or demonstration is stronger evidence of learning than a completion check alone.
