Casein allergy is quite prevalent among young children and babies.

Casein allergy is quite prevalent among young children and babies. Infants being breast-fed face a reduced risk for developing the allergy. In most cases, the allergy is outgrown by the time the child reaches 3-5 years old. On the other hand, some do not outgrow the allergy and have it until adulthood.

Products that contain casein

It is important to note the cow’s milk is comprised of casein protein. A variety of dairy products include casein but not all include the protein. As a protein, casein is typically present in products with reasonable to large content protein such as:

  • Yogurt
  • Low-fat milk
  • Cheese
  • Kefir
  • Ice cream

Risk factors

Casein allergy generally arises once an infant grows up to 3 months of age and resolves once the time the child reaches 3-5 years of age. The precise cause for this is not fully known.

In studies conducted, some with the allergy who were exposed to trace amounts in their diet seem to outgrow the allergy more quickly than those who do not consume casein.

Children should not be presented with cow’s milk before reaching a year old since the body of infants could not tolerate the elevated amounts of protein and other nutrients present in cow’s milk.

It is suggested to stick with breastfeeding or formula milk until 6 months old when starting the introduction of solid foods. At this point, avoid feeding the child with foods that include milk and continue with breast milk or formula.
