Scientific assessment
Mostly true – Correct at its core, but with limitations or minor inaccuracies.
Certainty of evidence: moderate – Further research may still affect the assessment.
1. What was claimed?
Peanut causes most fatal food-allergy deaths.
2. What is demonstrably correct?
Correct for the cited US registry series (peanut and tree nuts >90%). UK national data support peanut/tree nut as the leading trigger group but at a much lower share: at least 46% (86 of 187) of food-anaphylaxis deaths, with the trigger unknown in more than a quarter, a declining nut share, and cow's milk now the most common single cause in school-aged children (I-LEG-12).
3. What is wrong or exaggerated?
The fatal-anaphylaxis incidence among food-allergic people is about 1.81 per million person-years (Umasunthar 2013), lower than accidental death in the general European population. Non-allergic people are not at risk. Avoidance of peanut in infancy increased peanut allergy in high-risk infants (13.7% vs 1.9%) in the LEAP trial; LEAP does not address the share of deaths caused by peanut (its introduction calls peanut allergy the leading cause of food-allergy deaths) but limits any advice to avoid peanuts. The '>90%' figure is specific to the US registry and is not replicated in UK data.
4. What remains unclear?
Country patterns vary over time.
5. Which studies support it?
Bock 2001, 2007; Baseggio Conrado 2021; Moneret-Vautrin 1999 (lupin cross-reactivity).
6. Which studies contradict it?
Umasunthar 2013 (absolute risk); Du Toit 2015 (early introduction prevents allergy).
7. What applies to Germany and Europe?
Peanut is a mandatory-labelled allergen in the EU; general avoidance is not recommended.
8. What is known about Egypt?
No Egyptian fatal-anaphylaxis data reviewed.
9. What practical conclusion is appropriate?
Diagnosed allergy requires strict avoidance and an adrenaline auto-injector; non-allergic people need not avoid peanuts; infants at risk should be introduced early under medical guidance.
Assessment details
- Rationale for certainty of evidence
US registry (32 deaths) and UK national data (≥46% of deaths due to peanut or tree nut) agree that peanut/tree nut are leading causes; in UK school-aged children cow's milk is now the most common single cause. Absolute risk is very low and limited to allergic people.
- Source quality
Archive cites registry data correctly but omits absolute risk and the allergy-only scope.
- Regional transferability
European data (UK) show a similar but not identical pattern.
- Individual exceptions
Only people with diagnosed peanut allergy must avoid peanuts; early introduction in at-risk infants reduces allergy (LEAP trial).
- Regional scope of the claim
- not specified
- Last reviewed
- 26 October 2026 provisional

What does the overall evidence say?
Editorial assessment based on the studies above – not itself a study result.
Which position is better supported?
Peanut and tree nuts are leading causes of fatal food anaphylaxis in allergic people (the >90% figure is US-registry-specific); this supports strict avoidance only for diagnosed allergy and early introduction for infants.
Why some studies weigh more
Registries establish the statement; RCT and guideline evidence determine the practical conclusion.
Is a causal relationship established? Yes, established IgE-mediated anaphylaxis is causal in allergic people.
Remaining uncertainty
Egyptian data absent.
Justified conclusion
Correct for allergic people; not a reason for anyone else, especially infants, to avoid peanuts.
Why do studies seem to disagree?
US (>90%) and UK (>=46%) shares differ because of registry design, time and unknown triggers.
Does this depend on the country?
- General biological effects
- Universal immunology.
- Eating habits
- Peanut consumption patterns differ by country.
- Origin of the food
- Not relevant.
- Contaminants
- Not applicable.
- National production conditions
- Not applicable.
- Legal rules
- EU allergen labelling.
- Actual monitoring data
- No Egyptian registry data found.
A regional difference that changes the conclusion is not supported by robust data.

In plain language
Peanuts and tree nuts are indeed among the most common causes of deaths from food allergy. But such deaths are rare even among people with a food allergy, and people without a peanut allergy are not at risk. A large trial showed that avoiding peanuts in babies at high risk made peanut allergy more likely, while early, guided introduction made it much less likely.
