Clear, compassionate support for delayed (non‑IgE) food allergies.
Structured elimination and reintroduction—with nutrition protected at every step.
What is a non‑IgE food allergy?
Non‑IgE allergies involve the immune system, but not the IgE antibodies seen in immediate (IgE‑mediated) reactions. Symptoms are typically delayed and often affect the gut—think vomiting, diarrhoea, bloating, mucousy or bloody stools, reflux, congestion or eczema. Because the response is delayed, there is no reliable skin‑prick or blood test to diagnose non‑IgE allergy. The gold standard is a clinically guided elimination and reintroduction.
Making sense of delayed food reactions.
Allergies are common in childhood, and some children are particularly sensitive (atopic) to foods and environmental triggers. Non‑IgE food allergies don’t appear straight away—they’re delayed reactions that can surface 24–72 hours after eating, which makes them harder to spot and easy to confuse with intolerances or other gut issues. At Cubs Paediatric Dietetics, we help families understand what’s going on and guide them through a safe, structured plan to identify triggers without compromising nutrition or growth.
Common triggers
- cow’s milk and soy proteins, wheat and egg (others possible).
Types of non‑IgE presentations (examples)
- FPIAP (Food Protein‑Induced Allergic Proctocolitis): blood ± mucous in stools; baby usually well otherwise.
- Food Protein‑Induced Enteropathy: loose stools, bloating, poor weight gain; secondary lactose malabsorption may occur.
- FPIES (Food Protein‑Induced Enterocolitis Syndrome): delayed, repetitive vomiting 2–4 hours after a trigger (e.g., rice, cow’s milk, soy, oats, egg, sweet potato or chicken), followed by lethargy and loose stools.
- Eosinophilic Oesophagitis / EGID: feeding pain, slow eating, food impaction; diagnosed by a gastroenterologist.
How we help
We combine clinical expertise with family‑centred care to make non‑IgE allergy management clear, safe and achievable:
- Structured elimination & reintroduction — one change at a time, over set timeframes, to pinpoint true triggers.
- Nutrition safeguarded — like‑for‑like swaps and balanced menus to protect energy, protein, calcium, iron and micronutrients.
- Breastfeeding support — maternal exclusion plans with appropriate alternatives and supplements.
- Allergy ladders — stepwise exposure when ready, to build tolerance safely.
- Joined‑up care — collaboration with your GP/paediatrician and allergy/gastro teams where needed.
What to Expect
1. Comprehensive Assessment
History, growth, feeding pattern, symptom diary, and current diet.
2. Personalised Plan
Clear elimination targets, substitutes, recipes, and label‑reading guidance.
3. Reintroduction & Ladders
Supervised challenges to confirm triggers; tolerance‑building when appropriate.
4. On-going Support
Regular reviews to adjust the plan as your child grows and symptoms evolve.
Available in-person (Brisbane) or via secure telehealth.
FAQs
No. Because reactions are delayed, SPT/RAST are not diagnostic. We use a structured elimination and reintroduction under clinical guidance.
Yes—for diagnostic clarity we exclude the suspected allergen for about a month, then reintroduce for three days (or until symptoms reappear). No other diet changes during the challenge.
Often, yes. Our goal is long‑term resolution—first comfort, then tolerance. Ladders help build this safely over time.
We manage complex, multi‑allergy cases routinely and coordinate with your medical team to keep care safe and cohesive.
Not with our support. We provide nutrient‑dense alternatives and, when appropriate, short‑term supplements for optimum growth.
