Itchy skin is a sign that your body may be reacting to food you are eating. Certain foods can cause itchy skin, and these foods should be avoided.
Foods that can cause itchy skin
Itchy skin is a common problem that can be caused by a variety of factors. But did you know that some foods can actually cause your skin to itch?

There are two main types of skin reactions that can be caused by food: allergies and irritants. Allergies occur when your immune system reacts to a particular food protein, while irritants are substances in food that can directly irritate your skin.
Symptoms of a food allergy include hives, swelling, redness, and itching. If you have a severe allergic reaction (anaphylaxis), you may also experience trouble breathing, dizziness, and even unconsciousness.
Food irritants, on the other hand, usually cause more localized reactions, such as itching and redness in the area where you came into contact with the food.
Some common foods causing itchy skin reactions include:
- Nuts
- Shellfish
- Milk
- Eggs
- Wheat
- Soy
- Fish
The itchiness caused by these foods and subsequent scratching can then lead to flare-ups or worsening of dermatitis symptoms. In most cases, this is caused by specific proteins found in food, which the immune system identifies as harmful and produces antibodies to fight against.
Symptoms
Symptoms of an itchy skin reaction can range from mild to severe. They may include:
- Hives
- Rash
- Itching
- Swelling of the lips, face, or tongue
- Wheezing or trouble breathing
If you experience any of these symptoms after eating a particular food, it’s important to see your doctor to confirm whether you have an allergy. Allergic reactions can be serious and even life threatening.

Food groups which cause Itchy skin
There are so many food allergies nowadays. Some of the prominent ones are mentioned below:
Milk
Symptoms of a milk allergy include hives, wheezing, and digestive problems. Symptoms that may take longer to develop include loose stools, abdominal cramps. Many kids outgrow milk allergies, but not all children do. Milk allergies are different from lactose intolerance, though both can cause digestive problems.
Among those allergic to them, exposure can cause swelling of the lips, tongue, or throat, as well as itching or tingling around the mouth.
It may also lead to vomiting, diarrhea, stomach cramps, and wheezing. Treatment involves avoiding dairy products and foods that contain milk, including yogurt, cheese, butter, and ice cream.
Wheat
Wheat allergies are caused by exposure to the proteins found in wheat, including albumin, gliadin, globulin, and gluten. This can cause issues like itching, digestive distress, and respiratory problems.
Some research shows that wheat allergies are more common among those with underlying conditions like asthma, eczema, or seasonal allergies.
Wheat is a common ingredient in bread, but it’s also in food you may not expect, such as hot dogs and soy sauce. A wheat allergy is different from a gluten allergy.
Those with an allergy to wheat need to avoid all foods that contain wheat, including bread, flour, pasta, crackers, couscous, bulgur, farro, and farina.
It’s also important to read food labels carefully, as wheat is sometimes also found in products like salad dressings, sauces, soups, and processed meats.
Soy
This allergy is caused by a reaction to soy protein, which is found in many soy-based products like soybeans, edamame, miso, tofu.
Soy allergies can cause several side effects, including atopic dermatitis, which is characterized by itching and inflammation of the skin especially on the face and mouth.
It may also cause other adverse health effects, including swelling, tingling of the mouth, stomach pain, and wheezing.
Fish
Fish allergies are caused by an allergic reaction to finned fish such as tuna, salmon, catfish, and cod. An allergy to finned fish, such as tuna or salmon, is different from an allergy to shellfish, such as lobster. Symptoms include skin rash, nausea, diarrhea, headaches, and stuffy nose.
Among those with a fish allergy, exposure to specific proteins found in finned fish can cause hives, itching, stomach pain, and congestion.
Nuts
Nuts are another common cause of anaphylaxis from food. There are many tree nuts, including cashews, almonds, walnuts, and pine nuts. An allergic reaction may come from the nut itself or nut-based oils, butter, flours, or milks. Between 25% and 40% of people who have a peanut allergy also are allergic to at least one type of tree nut.
Allergic reactions are caused by the presence of specific proteins in tree nuts, including oleosins, legumin, vicilins, and 2S albumins. Some of the symptoms caused by an allergic reaction to tree nuts include itchiness, tingling, skin redness, and swelling of the mouth.
Eggs
One of the main symptoms of an egg allergy is hives, which can cause the skin to become itchy, red, and swollen. An allergy to hen’s eggs could cause hives and digestive issues.
An egg allergy occurs when the body’s immune system reacts to the proteins found in egg yolks and egg whites. If you’re allergic to chicken eggs, you may also be allergic to other types of eggs, such as goose, duck, turkey, or quail.
If you experience itching or other symptoms and suspect you may have a food allergy, speak with your healthcare provider immediately to determine the best course of treatment.
Remedies
If you have a mild reaction to a food, you may be able to treat it at home with over-the-counter antihistamines or hydrocortisone cream. If you have a more severe reaction, you may need to see a doctor for treatment with steroids or other medication.
If you have itchy skin that is not caused by an allergy, there are a number of home remedies that may help to relieve your symptoms. These include using cool compresses or taking oatmeal baths. Moisturizing your skin regularly can also help to prevent the itchiness from getting worse. If home remedies do not relieve your symptoms, see your doctor for further treatment options.
