Do soy protein-based formulas have a role in preventing allergy or in managing non-specific gastrointestinal symptoms such as infantile colic and regurgitation?

• A. Yes, they prevent allergy
• B. No, they have no role
• C. They reduce regurgitation
• D. They treat infantile colic

Answer: (B)

Soy protein–based formulas do not prevent allergy and do not reliably relieve non-specific GI symptoms like infantile colic or regurgitation. There’s no consistent evidence that switching to soy reduces the risk of developing allergies, and for GI symptoms, colic and regurgitation are typically managed with feeding practices or other formula options (such as hydrolyzed or thickened formulas) rather than soy. In some cases, soy can even pose a risk of soy protein sensitivity or cross-reactivity, so it isn’t recommended for allergy prevention or for treating these GI issues.
