Lactose intolerance and cow's milk protein allergy are two common reasons for avoiding dairy foods.
The most common type of lactose intolerance is primary lactose intolerance, which affects more than 70% of the world’s population (1). Additionally, cow's milk protein allergy is reported in approximately 2-5% of children, making it one of the most common allergies seen in infants and children (2,3,4).
