Allergic reactions to foods are very common and often very dangerous too. Other allergies are triggered by microscopic protein particles that are inhaled or come into contact with the skin. But food allergies usually involve proteins that have been ingested. Accordingly, exposure to the allergy-provoking substance is often greater. If you find you aren’t sure what is causing an allergy, look to the nine foods listed here.
Allergy to cow’s milk is the most common food allergy among infants and young children, affecting about 2.5 percent of kids under the age of three. Milk allergy is not the same as being lactose intolerant. The two conditions aren’t even related. Lactose intolerance means that a person has a hard time digesting the sugar that’s in milk. A milk allergy is an overreaction of the immune system in response to protein and it can be deadly. Most children eventually outgrow their milk allergy but blood tests that measure the presence of milk antibodies can be used to check.
