Top 12 Allergenic Foods

 There are a lot of things that can trigger allergies, and food is one of the most common triggers. If you have food allergies, it’s important to know what foods to avoid. In this blog post, we’ll discuss the top 12 allergenic foods and why they’re so problematic for people with allergies.

Cow's milk

Cow's milk is one of the top allergenic foods. Milk allergies are most commonly found in infants and young children, but can occur at any age. Symptoms of a milk allergy can include:

- gastrointestinal distress (nausea, vomiting, diarrhea)
- skin reactions (hives, eczema, swelling)
- respiratory problems (wheezing, asthma)
- anaphylaxis (a severe allergic reaction that can be life-threatening)

If you or your child has a milk allergy, it's important to avoid all products that contain cow's milk protein. This includes milk itself, as well as cheese, butter, yogurt, ice cream, and anything else made with cow's milk. Many processed foods also contain small amounts of cow's milk protein, so it's important to read labels carefully.


Fish are a common allergenic food, with reactions ranging from mild to life-threatening. The most common fish allergens are finfish, such as salmon, tuna, and halibut, but shellfish like shrimp and lobster can also cause reactions.

Most people with fish allergies are allergic to more than one type of fish. Fish allergy symptoms usually occur within minutes to an hour after eating fish or coming into contact with fish protein. Symptoms can include hives, itching, swelling, trouble breathing, and in severe cases, anaphylaxis.

People with fish allergies need to be careful when choosing foods and should always check labels for the presence of fish or shellfish ingredients. There is no cure for fish allergies, so the best way to prevent reactions is to avoid fish altogether.
