Cow's milk alternatives for children with cow's milk allergy and beyond.

Cow's milk allergy (CMA) is one of the most common food allergies in the first years of life, with worldwide prevalence estimated to range from 2% to 5%. While the majority of children with CMA will eventually develop tolerance to cow's milk proteins (it is estimated that >75% of children with CMA develop tolerance to cow's milk proteins by the age of 3 years, and >90% develop tolerance by the age of 6 years), the selection of an appropriate cow's milk (CM) alternative for those with CMA is vital to ensure adequate growth and development during childhood. The increasing number of CM alternative products on the commercial market with markedly different nutritional content and micronutrient fortification adds a layer of complexity that can be challenging for both families and clinicians to navigate. This article aims to provide guidance and clarity to Canadian paediatricians and primary care clinicians on recommending the most appropriate, safe, and nutritionally optimal CM alternatives for individuals with CMA, and beyond.
