How to know if my child is lactose intolerant?

The child lactose intolerant is one whose body does not produce the enzyme lactase . This enzyme allows us to correctly process and assimilate the lactose contained in the food we eat. Lactose, also known as “milk sugar”, is present in milk produced by female mammals.

Lactose helps the correct absorption of calcium and promotes mineralization of bones. Foods derived from dairy products contain lactose , among which are milk, yogurt, ice cream, butter and cheeses.
