Milk allergy is one of the most common food allergies, especially in children. While most outgrow their milk allergy by late childhood, 20% remain allergic into their teenage years.
For people with food allergies, avoidance of the culprit food is the only reliable treatment option. Unfortunately, accidental consumption of these culprit foods is common, so people with food allergies always need to be prepared to treat an allergic reaction.
Since milk and dairy foods are commonly foods, especially in children’s diets, accidental exposure to milk-containing foods is common, even when a person is actively trying to avoid eating milk.
A study published in 2009 showed that 40% of milk-allergic children experienced an allergic reaction from the accidental ingestion of milk during a one-year period of time. This is despite actively trying to follow a milk-free diet. While the majority of these allergic reactions were mild, 15% were severe, especially in children with asthma.
The bottom-line from this study, as well as what I’ve learned from my experience as a practicing allergist, is that avoidance of a culprit food in a person with food allergies is not always possible, and therefore being prepared to treat a food allergy reaction is very important.
