Top Food Triggers of Dermatitis: What to Avoid for Better Skin Health

Certain foods are thought to contribute to dermatitis flare-ups by triggering allergic reactions or inflammation in the body. Identifying these triggers is crucial in managing the condition.

 

10 Common Food Triggers Involved in Dermatitis

Here are 10 Common Food Triggers Involved in Dermatitis.

  1. Soy
  2. Peanuts
  3. Eggs
  4. Shellfish
  5. Wheat
  6. Dairy Products
  7. Citrus Fruits
  8. Cow’s Milk
  9. Gluten
  10. Tomatoes

 

How Soy Can Lead to Dermatitis

  • Soy is often linked to inflammatory responses in the body, triggering itching, inflammation, and even hormonal acne.
  • The body produces IgE antibodies, leading to hypersensitivity reactions and dermatitis symptoms.

Soy Allergy

  • A soy allergy can cause respiratory symptoms (wheezing, runny nose, difficulty breathing), skin reactions (tingling around the mouth, itching, rash, redness), and gastrointestinal symptoms (abdominal pain, diarrhea).
  • Symptoms typically appear within minutes to hours of exposure.

 

Peanuts & Dermatitis

  • Peanut allergies can lead to airway swelling, difficulty breathing, vomiting, and low blood pressure.
  • Peanuts contain proteins that the body mistakenly identifies as harmful, triggering the release of chemicals that cause allergic reactions.

 

Eggs & Dermatitis

Eggs can lead to dermatitis through two mechanisms:

  1. Immediate IgE-mediated reactions
  2. Delayed reactions to egg proteins

Egg proteins like ovotransferrin, ovomucoid, and ovoglobulin can disrupt the skin barrier, leading to inflammation and increased skin permeability.

 

Shellfish & Dermatitis

Shellfish contains proteins such as tropomyosin and arginine kinase, which can cause blisters, rashes, dry, cracked, and scaly skin when a person is allergic.

 

Wheat & Dermatitis

  • Wheat contains proteins like gliadin and gluten, which are known to trigger skin inflammation and flare-ups of dermatitis.

 

Dairy Products & Dermatitis

  • Dairy contains proteins such as casein, whey, and lactoglobulin, which can cause red welts, rashes, and itching in sensitive individuals.

 

Citrus Fruits & Dermatitis

Citrus fruits like oranges, lemons, limes, and grapefruits can trigger several types of dermatitis:

  1. Phytophotodermatitis (reaction from citrus and sunlight)
  2. Contact dermatitis (reaction from handling fruit)
  3. Hives (allergic reaction causing welts on skin)

 

Tomatoes & Dermatitis

  • Tomatoes contain proteins like lycopene, salicylates, and histamine, which can lead to itchy, red rashes on the skin.

 

Understanding Food Sensitivities

Each individual with dermatitis may have different food sensitivities. It's essential to identify personal triggers and adjust your diet accordingly for better skin health.

 

Diagnostic Tests for Food Triggers

To identify food triggers, common tests include:

  1. Skin Prick Test: Small amounts of allergens are applied to the skin, and the reaction is observed.
  2. Blood Tests: Measures IgE levels to identify allergic responses.
  3. Elimination Diet: Certain foods are eliminated from the diet for a set period to observe any changes in symptoms.

 

Preparation for Allergy Testing

  • Avoid taking over-the-counter nasal sprays, cold medications, or anti-allergic drugs before the test.
  • Do not apply any skin care products to the testing area on the day of the test.

 

Risks of Allergy Testing

Although rare, allergy testing can cause severe reactions, such as anaphylaxis, which can lead to skin, respiratory, and abdominal symptoms.

 

Symptoms after Allergy Testing

  • Itching
  • Stuffy nose
  • Red, watery eyes
  • Skin rash

 

Allergy testing can be an effective tool in managing dermatitis by pinpointing food triggers and helping to control symptoms.
