Food Allergies

Food allergies are one of the most challenging aspects of feeding kids. Many parents feel a lot of stress when introducing allergens or feel completely alone when they get a diagnosis like FPIES. There is so much parents want to know about food allergies and so much conflicting information available.

Wheat Allergy

Wheat allergy ma affect up to 1% of children in the US. Up to two thirds of children with a wheat allergy may outgrow it by the time they are 12 years old.
It is different from celiac disease which is an autoimmune system that often affects the gastrointestinal tract.

Milk Allergy

Milk allergy is the most common allergy in infants and young children, affecting around 2.5% of children under the age of 3. There are actually 2 categories of milk allergies: IgE mediated and non-IgE mediated. We often see non-IgE mediated milk allergy in young infants and many will outgrow it by their first birthday. This article, however, will be focusing on IgE mediated milk allergy.

When a person with milk allergy is exposed to the proteins in milk, the proteins bind to IgE antibodies that trigger the immune system, causing a reaction. Up to 70% of children with this allergy can tolerate milk baked into foods. Once the milk has been heated, it changes the structure of the protein enough so that the body doesn’t respond to it. Tolerating baked milk while young is a good sign that a child may outgrow their milk allergy. Up to 75% of children will outgrow their milk allergy.

Best Formula for Milk Protein Allergy

Figuring out which formula to choose can be extremely stressful (ignoring the shortage at hand), but choosing a formula for a baby with a milk protein allergy is even more complicated. Balancing out which formula will be best for your baby while also keeping in mind the rising costs of formula as they get more specialized is challenging, to say the least.

Shellfish Allergy


Shellfish allergies are the most common food allergies in adults and a common allergy in children as well (1). It is incredibly rare for someone to outgrow a shellfish allergy. The most common shellfish allergy is an allergy to shrimp. Similar to fish, many people (about 60%) will not experience their first reaction until they are adults.

9 Food Allergy Back to School Tips

As summer ends and school heads back into session, you may be concerned about what to do if your child has a food allergy. While all schools handle food allergies slightly differently, there are some common themes. It’s important to have a plan in place and make sure that everyone is on board, including your child.

Fish Allergy in Babies

Unlike some of the other top allergens, many people (up to 40%) with a fish allergy won’t develop a reaction until they are an adult. This doesn’t mean that fish allergy can’t happen in babies, but it’s important to keep it in the diet and watch for a reaction all throughout life.
Finned fish are different from shellfish. Being allergic to one doesn’t mean that you’ll be allergic to the other. In one study, salmon, tuna, catfish, and cod were the fish that seemed to cause the most reactions. Most people are told to avoid all types of finned fish if they are allergic to one type.

Sesame Allergies

Tree nut allergies are one of the 9 most common food allergies. The most common tree nut allergies are walnut, almond, hazelnut, pecan, cashew, and pistachio (1). It’s possible to be allergic to only 1 kind of nut, but about half of kids who are allergic to 1 nut are also allergic to another.
Tree nut allergies are usually lifelong with only about 9% of children outgrowing their allergy.

Soy Allergy in Baby

Soybean allergy tends to be more common in babies and young children, with many outgrowing it as they age. It is estimated that about 0.4% of infants in the US are allergic to soy.
Soybeans are legumes, just like beans, peas, lentils and peanuts. Up to 88% of people with soy allergies are also allergic or significantly sensitized to peanuts, although the reverse isn’t true. People with soy allergies are more likely to be allergic to major allergens like peanuts, tree nuts, egg, milk, and sesame, than to other legumes.
