From the Guidelines

There is no direct relationship established between peas and allergic reactions in babies in the provided evidence, but as a legume, peas can potentially trigger allergic responses in sensitive individuals. The provided studies primarily focus on peanut allergies, with the most recent and highest quality study being from 2020 1. This study discusses the implementation of addendum guidelines for peanut allergy prevention and highlights the importance of early introduction of peanut-containing foods in infants' diets to decrease the development of peanut allergy.

Key Points to Consider:

  • Peas are legumes and can cause allergic reactions in some babies, although they are not among the most common food allergens for infants.
  • Symptoms of a pea allergy may include hives, swelling, vomiting, diarrhea, breathing difficulties, or in severe cases, anaphylaxis.
  • Parents should introduce peas gradually when starting solid foods, typically around 6 months of age, and watch for any adverse reactions.
  • If an allergic reaction occurs, stop feeding peas immediately and consult a healthcare provider.
  • For severe reactions with breathing difficulties or significant swelling, seek emergency medical attention.
  • The allergic response happens because the immune system mistakenly identifies proteins in peas as harmful and releases chemicals like histamine that cause inflammation and allergy symptoms.
  • Most children outgrow pea allergies, but some may have lifelong sensitivities, as noted in general knowledge about food allergies, although specific studies on peas are not provided in the evidence 1.

Introduction to Solid Foods:

When introducing solid foods to babies, it's essential to do so gradually and monitor for any signs of allergic reactions. The American Academy of Pediatrics recommends introducing solid foods at around 6 months of age, and the provided evidence suggests that early introduction of peanut-containing foods can help prevent peanut allergies 1.

Allergic Reactions and Prevention:

While the evidence does not directly address pea allergies, it highlights the importance of being aware of potential allergic reactions when introducing new foods to infants. By introducing foods gradually and monitoring for signs of allergy, parents and healthcare providers can help prevent and manage food allergies, including those to legumes like peas.

From the Research

Relationship Between Peas and Allergic Reactions in Babies

  • There is limited direct evidence on the relationship between peas and allergic reactions in babies, as most studies focus on common allergenic foods such as peanuts, eggs, and milk.
  • However, some studies suggest that introducing potentially allergenic foods, including peas, at an early age may help prevent food allergies in infants 2.
  • A systematic review found that delayed introduction of solid foods, including allergenic foods, was not associated with decreased risk for allergic diseases among high and low-risk infants, and later introduction was associated with increased risk for allergy development 2.
  • The American College of Allergy, Asthma and Immunology recommends introducing solids into an infant's diet at 6 months, with caution for foods that are more allergenic, but does not specifically mention peas 3.
  • Other studies focus on the management of anaphylaxis, a life-threatening systemic allergic reaction, and do not provide direct evidence on the relationship between peas and allergic reactions in babies 4, 5.
