Why might soy formula be preferred over breast milk or cow milk formula?

Soy formula may be preferred over breast milk or cow's milk formula primarily because it addresses the specific dietary needs of infants who are lactose intolerant or unable to digest lactose. Lactose is the sugar found in breast milk and cow's milk; infants who are lactose intolerant have difficulty processing this sugar, which can lead to gastrointestinal discomfort and issues such as gas, bloating, and diarrhea. Soy formula provides an alternative that does not contain lactose, allowing these infants to receive adequate nutrition without experiencing adverse side effects.

While soy formula does have different nutritional profiles compared to breast milk and cow's milk formula, the key reason for its preference among certain populations lies in its suitability for those with lactose intolerance. This option is especially significant for caregivers seeking the best feeding option for their infants who react negatively to lactose-containing products.
