Cow's milk protein allergy today is a matter of concern for many parents. When your child is diagnosed or suspected by a doctor to have a cow's milk protein allergy, you will probably wonder how to take better care of your baby. The following article will help you answer that question.
1. What is cow's milk protein allergy?
When a child has a food allergy, the child must follow a hypoallergenic diet. This means that your child cannot eat a food to which they are allergic or any product containing that food. Things your child is allergic to are called allergens.
Cow's milk protein allergy is an abnormal reaction to the proteins found in cow's milk. Milk allergy is most common in infants and young children. As they get older, many children will develop a milk allergy. Milk and dairy products are found in many foods. Conspicuous forms of milk are cream, cheese, butter, cream, and yogurt. Milk and dairy products can also be potential sources of risk in commonly eaten foods. To stay away from foods that contain dairy products, you must read food labels.
Milk provides an important source of calcium. Your child needs calcium for healthy bones, teeth and nerves. Talk to your child's health care provider about foods with calcium that you can give your child. Some examples are green leafy vegetables, calcium-fortified orange juice, figs, tofu and dried beans.

2. Causes of cow's milk protein allergy
Milk allergy is most commonly caused by an allergy to cow's milk, although some people are allergic to the milk of other animals such as goats, sheep, and buffalo.
In all allergies, the immune system reacts to activate molecules (allergens). Your immune system produces antibodies that detect the allergen, trigger inflammatory reactions, and release a chemical called histamine, both of which cause allergy symptoms.

4. What to do when the child is allergic to cow's milk protein?
If you or your child has been diagnosed with a milk allergy, treat it by completely avoiding milk or dairy products. This can be difficult to do. Health professionals advise that children who are allergic to cow's milk are often allergic to goat's milk and as such, it may not be possible to substitute cow's milk with milk of animal origin.
To avoid milk and dairy products, read food labels and avoid foods that contain milk or dairy products.
Only remove milk and dairy products from the diet of a baby or young child under strict medical supervision. Your doctor will need advice on alternative sources of calcium and protein, which are especially important for children. Alternative infant formulas also need to be carefully monitored. For example, some children with a cow's milk allergy will not be able to tolerate soy products.
