According to results of a recent study, the prevalence of food protein-induced enterocolitis syndrome (FPIES) due to avocado consumption appears to be higher than previously believed.
FPIES is a gastrointestinal food-associated hypersensitivity that often affects infants and toddlers. Its symptoms are: vomiting, diarrhea, fatigue and pallor. The data regarding its incidence is limited. However, it is estimated to be 1.5 to 30 per 10,000. Although avocado is considered to be a low-risk food according to international consensus guidelines, recent data may prove otherwise.
“We report a perceived higher prevalence of FPIES to avocado, with 3 out of 14 FPIES patients presenting to a single provider in NYC over a 12-month period reporting FPIES reactions with avocado,” write the authors.
In these three cases, 6- to 8-month old patients developed repetitive vomiting 1-4 hours after ingestion of avocado and two experienced symptom recurrence following repeat exposures.
Based on the cases presented in this paper, the authors concluded that FPIES reactions with avocado appear to be more common than originally believed. “Knowledge of avocado as a potentially emerging trigger will aid timely diagnosis and guide complementary food introductions.”
