Which is the BEST indication for the use of a soy-based infant formula?

• A. Diarrhea
• B. Cow's milk protein allergy
• C. Galactosemia
• D. Regurgitation with feeds

Answer: (C)

Galactosemia requires a galactose-free formula, so a soy-based infant formula is indicated because it provides nutrition without galactose. Lactose-containing cow’s milk formulas release galactose, which must be avoided in this condition, and soy-based formulas are typically lactose-free, offering a galactose-free option for the infant. The other scenarios aren’t specific indications for choosing a soy formula. While some infants with cow’s milk protein allergy may temporarily use alternative formulas, soy formula can cross-react with cow’s milk proteins and isn’t universally tolerated, so it isn’t the best first-line choice for allergy. Diarrhea or regurgitation with feeds aren’t addressed specifically by switching to soy; they’re managed with hydration, appropriate feeding strategies, or different formula types as clinically indicated.
