People with soy allergies may also be sensitive to other legumes, though cross-reactivity is generally low. However, they should be cautious with:

• Peanuts (also a legume)
• Other beans and legumes like lentils, chickpeas, and peas
• Some individuals may react to other allergens due to shared protein structures.

• If experiencing allergic reactions after consuming soy-based products.
• In infants or children who react to soy formula or foods containing soy.
• If there’s a history of other food allergies, especially legume allergies.
• Prior to introducing soy into a child’s diet, particularly if there’s a family history of allergies.

• Avoid foods and products containing soy ingredients.
• Read food labels carefully, as soy is a common ingredient in processed foods.
• Be aware of alternative names for soy, including soy lecithin, soy protein, and tofu.
• In restaurants, inform staff about the soy allergy to avoid cross-contamination.
• For mild reactions, over-the-counter antihistamines might be effective.
• Carry an epinephrine auto-injector if there’s a risk of severe reactions.
• Consult with an allergist for specific advice, especially regarding the introduction of soy in diets and potential allergy testing.
