Food Allergies
Food allergies are the immune system response to specific proteins found in certain foods.
When individuals with food allergies consume these allergenic proteins, their immune system identifies them as harmful and releases chemicals, such as histamine, to defend the body. This immune response can lead to various symptoms ranging from mild to severe.
Symptoms of a food allergy can include skin reactions (such as hives or eczema), digestive problems, respiratory issues (such as wheezing or difficulty breathing), and in severe cases, anaphylaxis—a life-threatening reaction that requires immediate medical attention.
It's important for individuals with food allergies to carefully read food labels, communicate their allergies to restaurants and others preparing their food, and carry an epinephrine auto-injector in case of a severe reaction. If someone suspects they have a food allergy, they should consult with a healthcare professional for proper diagnosis and management.
Common Food Allergens
Eggs
An egg allergy is an immune system reaction to proteins found in eggs. This allergy is more common in children than in adults, and many children outgrow it as they get older. The symptoms of an egg allergy can range from mild to severe and may include skin reactions (such as hives or eczema), digestive symptoms (such as abdominal pain or vomiting), respiratory symptoms (such as sneezing or wheezing), and in severe cases, anaphylaxis, which is a potentially life-threatening reaction.
If someone is suspected of having an egg allergy, it is important to consult with a healthcare professional for proper diagnosis and management. In some cases, individuals with egg allergies may need to avoid not only whole eggs but also foods that contain egg ingredients, as well as certain vaccines and medications that may contain egg proteins.

Fish
A fish allergy is an immune system reaction to proteins found in fish. When someone with a fish allergy comes into contact with fish proteins, their immune system mistakenly identifies them as harmful, leading to the release of chemicals like histamine. This can cause various symptoms ranging from mild to severe, such as hives, itching, swelling, abdominal pain, nausea, vomiting, diarrhea, difficulty breathing, and in severe cases, anaphylaxis.
It's important for individuals with fish allergies to avoid consuming fish and be cautious about cross-contamination in food preparation. In some cases, even inhaling cooking vapors or touching surfaces contaminated with fish can trigger allergic reactions. If someone suspects they have a fish allergy, they should consult with a healthcare professional for proper diagnosis and guidance on managing the allergy.

Tree Nuts
A tree nut allergy is an allergic reaction to proteins found in certain tree nuts. Tree nuts include a variety of nuts such as almonds, walnuts, cashews, pistachios, hazelnuts, and others. The allergic reaction occurs when the immune system mistakenly identifies proteins in tree nuts as harmful and releases chemicals, such as histamines, to protect the body. Symptoms of a tree nut allergy can range from mild to severe and may include hives, itching, swelling, abdominal pain, difficulty breathing, and in severe cases, anaphylaxis. It's important for individuals with a tree nut allergy to avoid consuming tree nuts and be cautious about cross-contamination in food products. If someone suspects they have a tree nut allergy, they should consult with a healthcare professional for proper diagnosis and management.
Shellfish
A shellfish allergy is an allergic reaction to proteins found in shellfish. Shellfish include crustaceans (such as shrimp, crab, and lobster) and mollusks (such as clams, mussels, oysters, and scallops). The allergic reaction can range from mild symptoms, such as hives or itching, to more severe reactions, including difficulty breathing and anaphylaxis.
It's important for individuals with a shellfish allergy to avoid consuming shellfish and to be vigilant about checking food labels, as shellfish ingredients can sometimes be hidden in processed foods. In severe cases, people with shellfish allergies may need to carry an epinephrine auto-injector (such as an EpiPen) to quickly treat an allergic reaction.

Milk
A milk allergy is an immune system reaction to proteins found in cow's milk. This allergic reaction can occur when the immune system mistakenly identifies certain proteins in milk, such as casein or whey, as harmful substances. Symptoms of a milk allergy can range from mild to severe and may include skin reactions (such as hives), digestive issues, respiratory problems, and, in rare cases, anaphylaxis, which is a severe and potentially life-threatening reaction.
It's important for individuals with a milk allergy to avoid all sources of milk and its derivatives. In some cases, milk proteins may also be present in processed or packaged foods, so careful reading of ingredient labels is crucial for those with a milk allergy. If someone suspects they have a milk allergy, it's advisable to consult with a healthcare professional for proper diagnosis and management.

Wheat
A wheat allergy is an allergic reaction to proteins found in wheat. It is different from celiac disease, which is an autoimmune disorder triggered by gluten, a protein in wheat, barley, and rye. In a wheat allergy, the immune system identifies certain proteins in wheat as harmful and releases chemicals such as histamines to defend against them.
This immune response can lead to various symptoms, including skin rash, digestive issues, difficulty breathing, and in severe cases, anaphylaxis. It's important for individuals with a wheat allergy to avoid wheat-containing products and carefully read food labels to prevent accidental exposure. If someone suspects a wheat allergy, they should consult with a healthcare professional for proper diagnosis and guidance on managing the condition.

Soy
A soy allergy is an immune system response to proteins found in soybeans. When someone with a soy allergy comes into contact with soy proteins, their immune system mistakenly identifies these proteins as harmful, leading to the release of chemicals like histamines that cause allergic symptoms. Symptoms of a soy allergy can range from mild to severe and may include hives, itching, swelling, abdominal pain, diarrhea, and in severe cases, anaphylaxis.

Peanuts
A peanut allergy is an immune system reaction to proteins found in peanuts. It is a type of food allergy and can range from mild to severe. Symptoms of a peanut allergy can include hives, stomach cramps, nausea, vomiting, shortness of breath, and in severe cases, anaphylaxis—a life-threatening reaction that requires immediate medical attention.
People with peanut allergies need to avoid peanuts and peanut-containing products to prevent allergic reactions. In some cases, individuals may carry an epinephrine auto-injector (such as an EpiPen) to quickly treat severe reactions. It's essential for those with peanut allergies to carefully read food labels and inform others about their condition to ensure they avoid exposure to peanuts.

Gluten
Gluten allergy is commonly referred to as gluten sensitivity or non-celiac gluten sensitivity (NCGS). It is not a true allergy but rather a condition where individuals experience symptoms similar to those of celiac disease when consuming gluten. Gluten is a protein found in wheat, barley, rye, and their derivatives.
Unlike celiac disease, which is an autoimmune disorder where the ingestion of gluten leads to damage in the small intestine, gluten sensitivity does not involve an autoimmune response or damage to the intestinal lining. However, people with gluten sensitivity may experience various symptoms after consuming gluten, such as gastrointestinal issues, fatigue, headaches, and joint pain.
It's important to note that gluten sensitivity is distinct from celiac disease, which is a more severe and potentially serious condition. If someone suspects they have an issue with gluten, it's advisable to consult with a healthcare professional for proper diagnosis and guidance on managing their symptoms.
