Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, and inflamed skin. While the exact causes of eczema are still not fully understood, research suggests that certain foods may play a role in triggering or exacerbating the condition. In this article, we will delve into the relationship between food and eczema, exploring the potential culprits and the science behind their effects.
Understanding Eczema and Its Triggers
Eczema is a complex condition, and its development is influenced by a combination of genetic, environmental, and lifestyle factors. While the exact causes of eczema are still not fully understood, research has identified several triggers that can exacerbate the condition. These triggers include:
- Allergens, such as pollen, dust mites, and pet dander
- Irritants, such as soaps, detergents, and fragrances
- Stress
- Hormonal changes
- Certain foods
The Role of Food in Eczema
Food can play a significant role in eczema, particularly in individuals with food allergies or intolerances. When an individual with eczema consumes a trigger food, their immune system responds by releasing inflammatory chemicals, which can exacerbate the condition. The most common food triggers for eczema include:
- Dairy products
- Gluten
- Nuts and seeds
- Soy
- Fish and shellfish
- Eggs
Dairy Products and Eczema
Dairy products are a common trigger for eczema, particularly in individuals with a lactose intolerance or milk protein allergy. The proteins in milk, such as casein and whey, can stimulate an immune response, leading to inflammation and exacerbating eczema symptoms.
A study published in the Journal of Investigative Allergology and Clinical Immunology found that a significant proportion of individuals with eczema had a milk protein allergy, and that avoiding dairy products led to an improvement in symptoms.
Gluten and Eczema
Gluten, a protein found in wheat, barley, and rye, is another common trigger for eczema. Individuals with celiac disease or non-celiac gluten sensitivity may experience an immune response to gluten, leading to inflammation and exacerbating eczema symptoms.
A study published in the Journal of Clinical Gastroenterology found that individuals with celiac disease were more likely to have eczema, and that a gluten-free diet led to an improvement in symptoms.
Other Potential Food Triggers for Eczema
In addition to dairy products and gluten, other foods may also trigger or exacerbate eczema. These include:
- Nuts and seeds: Tree nuts, such as almonds and walnuts, and seeds, such as sesame and sunflower, are common allergens that can trigger eczema.
- Soy: Soy is a common ingredient in many foods, and some individuals may experience an immune response to it, leading to inflammation and exacerbating eczema symptoms.
- Fish and shellfish: Fish and shellfish are common allergens that can trigger eczema, particularly in individuals with a history of allergies.
- Eggs: Eggs are another common allergen that can trigger eczema, particularly in individuals with a history of allergies.
The Science Behind Food Triggers for Eczema
The exact mechanisms by which food triggers eczema are not fully understood, but research suggests that several factors are involved. These include:
- Immune system activation: When an individual with eczema consumes a trigger food, their immune system responds by releasing inflammatory chemicals, which can exacerbate the condition.
- Gut-skin axis: The gut and skin are connected through the gut-skin axis, a bidirectional communication network that allows the gut and skin to communicate with each other. When the gut is exposed to a trigger food, it can send signals to the skin, leading to inflammation and exacerbating eczema symptoms.
- Leaky gut syndrome: Leaky gut syndrome is a condition in which the gut lining becomes permeable, allowing toxins and undigested food particles to pass through the gut wall and into the bloodstream. This can lead to inflammation and exacerbate eczema symptoms.
How to Identify Food Triggers for Eczema
Identifying food triggers for eczema can be challenging, but there are several steps you can take to determine which foods may be exacerbating your symptoms. These include:
- Keeping a food diary: Keeping a food diary can help you track which foods you are eating and when your symptoms occur.
- Elimination diet: An elimination diet involves removing common trigger foods from your diet for a period of time and monitoring your symptoms.
- Food challenge: A food challenge involves reintroducing a trigger food into your diet and monitoring your symptoms.
Managing Eczema Through Diet
While there is no cure for eczema, managing the condition through diet can help alleviate symptoms and improve quality of life. Here are some tips for managing eczema through diet:
- Eat an anti-inflammatory diet: An anti-inflammatory diet rich in fruits, vegetables, whole grains, and omega-3 fatty acids can help reduce inflammation and alleviate eczema symptoms.
- Avoid trigger foods: Avoiding trigger foods, such as dairy products and gluten, can help reduce inflammation and alleviate eczema symptoms.
- Consider a probiotic: Probiotics are beneficial bacteria that can help maintain a healthy gut microbiome and reduce inflammation.

What is eczema and how is it related to food?
Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition characterized by dry, itchy, and scaly skin. While the exact cause of eczema is still unknown, research suggests that certain foods may trigger or exacerbate the condition in some individuals. This is because some foods can cause an allergic reaction or intolerance, leading to inflammation and skin symptoms.
In people with eczema, the skin’s natural barrier is compromised, making it more susceptible to irritation and inflammation. Certain foods can further disrupt this barrier, leading to increased symptoms. Common food culprits include dairy products, gluten, soy, and nuts, although the specific triggers can vary from person to person.
How do I know if a food is causing my eczema symptoms?
Identifying food triggers for eczema can be challenging, as symptoms may not appear immediately after consumption. Keeping a food diary can help track any potential correlations between food intake and eczema symptoms. Write down everything you eat and drink, as well as any symptoms that occur, to look for patterns.
If you suspect a particular food is causing your eczema symptoms, try eliminating it from your diet for 2-4 weeks to see if symptoms improve. If they do, reintroduce the food to confirm whether it is indeed a trigger. Consult with a healthcare professional or registered dietitian for personalized guidance on identifying and managing food triggers.
What are some common food culprits that can cause eczema symptoms?
Some common foods that may trigger or exacerbate eczema symptoms include dairy products, gluten, soy, nuts, shellfish, and citrus fruits. These foods can cause an allergic reaction or intolerance, leading to inflammation and skin symptoms. However, it’s essential to note that everyone’s triggers are different, and what causes symptoms in one person may not affect another.
In addition to these common culprits, some people may also react to food additives, such as artificial preservatives, flavorings, or colorings. Processed and packaged foods often contain these additives, which can be problematic for individuals with eczema.
Can food intolerances, such as lactose intolerance, contribute to eczema symptoms?
Yes, food intolerances, such as lactose intolerance, can contribute to eczema symptoms. Lactose intolerance occurs when the body is unable to digest lactose, a sugar found in milk and other dairy products. This can lead to inflammation and skin symptoms, including eczema.
