What is a milk allergy?

A milk allergy is the immune system's over-reaction to the protein in cow's milk, causing symptoms that range from an upset stomach or hives to life-threatening anaphylaxis. Milk is the most common allergen amongst infants and young children with around 2.5% of children in the U.S. suffering from a milk allergy. Milk allergies are very different from lactose intolerance, though their symptoms can be very similar. Lactose intolerance is not caused by the immune system but is a result of the small intestine not producing enough lactase, the enzyme that digests lactose. People with lactose intolerance experience symptoms of digestive discomfort like bloating and nausea, but it is not life-threatening.  

What is a tree nut allergy?

A tree nut allergy occurs when the immune system overreacts to the proteins in certain tree nuts and attacks them as if they were a threat to the body. This causes symptoms like rashes, stomach pain and trouble breathing. In extreme cases, consuming or coming into contact with tree nuts can cause anaphylaxis — a severe and life-threatening reaction that impairs breathing to the extent that it requires immediate treatment with an epinephrine auto-injector. Tree nuts are any nuts that grow on trees, such as almonds, cashews, pecans and walnuts. They do not include peanuts, which are legumes that grow underground, and differ from seeds such as sesame and sunflower seeds.  

What is a peanut allergy?

A peanut allergy occurs when the immune system mistakes the protein in peanuts as a threat to the body and reacts to attack it. This causes many of the classic symptoms like rashes, stomach pain and trouble breathing. In extreme cases, peanuts can cause anaphylaxis — a severe and life-threatening reaction that impairs breathing to the extent that it requires immediate treatment with an epinephrine auto-injector. A peanut allergy is different from other nut allergies. Peanuts are legumes that grow underground, similar to soybeans, peas and lentils, while tree nuts such as almonds, cashews, and walnuts grow on trees. Having a peanut allergy does not necessarily mean you will be allergic to other legumes, such as peas, beans and soybeans. However, studies show that around 35% of toddlers allergic to peanuts will also develop tree nut allergies.
