Why might soy formula be chosen over breast milk or cow milk formula for certain infants?

Choosing soy formula for certain infants is often based on their sensitivity to lactose, which is a sugar found in breast milk and cow's milk. Infants who are lactose intolerant or have a milk protein allergy may experience gastrointestinal distress when consuming products containing lactose or cow's milk protein. Soy formula provides a suitable alternative, as it is lactose-free and made from soy protein, allowing these infants to receive adequate nutrition without the adverse effects associated with lactose consumption.

This option highlights the importance of selecting a formula that meets the specific dietary needs of infants, particularly those with sensitivities or allergies. The other alternatives may not address the particular health requirements of these infants, as soy formula is not specifically distinguished by being higher in protein, lower in calories, or sweeter in taste compared to other options like breast milk or cow milk formula.
