What are the odds of a baby being lactose intolerant?

Answer 1

The odds of a baby being lactose intolerant vary by ethnicity and genetic factors, with estimates suggesting that around 2-3% of infants might be affected in populations of Northern European descent. In contrast, lactose intolerance is more common in certain ethnic groups, such as those of East Asian, West African, and Mediterranean descent, where rates can exceed 50-90% in some communities. It's important to note that most infants are born with the ability to digest lactose, as they consume their mother's milk. Lactose intolerance typically develops later in life rather than in infancy.
