Is Poor Nutrition Causing Your Eczema? Understanding the Link Between Diet & Eczema

By Dr. Diane Angela Fong, ND


Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by inflamed, itchy, and often painful patches of skin. While many people turn to topical treatments to manage their symptoms, there is growing evidence that what you eat may play a crucial role in the severity and frequency of eczema flare-ups. Poor nutrition can impact overall skin health, and specific dietary triggers might exacerbate eczema symptoms. In this blog, we will delve into the connection between diet and eczema, exploring how certain foods can influence your skin condition and what nutritional changes you can make to support healthier, calmer skin.


Poor nutrition can significantly impact the development and exacerbation of eczema symptoms. Research has elucidated several mechanisms through which dietary factors contribute to the pathogenesis of eczema.

Food Sensitivities & Allergies

Studies have highlighted the association between food allergies and eczema, demonstrating that certain foods can trigger both immediate and delayed eczematous reactions. Immediate reactions, mediated by IgE antibodies, can occur shortly after ingestion, while delayed reactions may manifest up to two days later, exacerbating symptoms of atopic dermatitis (AD). Food elimination diets, though beneficial for some individuals with AD, must be approached cautiously. While they may reduce symptom severity, their impact on the progression of AD remains unclear.

Nutrient Deficiencies

Nutrient deficiencies are pivotal factors in the pathogenesis of eczema, exerting multifaceted effects on immune function, skin barrier integrity, and inflammatory processes. Adequate levels of essential nutrients are crucial for the proper functioning of the immune system, which plays a pivotal role in regulating inflammatory responses and preventing allergic reactions associated with eczema. Moreover, nutrient deficiencies can compromise the structural integrity of the skin barrier, impairing its ability to retain moisture and protect against environmental irritants and allergens. This compromised barrier function not only exacerbates existing eczema symptoms but also increases susceptibility to external triggers. Additionally, inadequate intake of key nutrients can lead to dysregulated inflammatory responses, further exacerbating eczema symptoms and contributing to chronic inflammation.

Here's how specific nutrients impact the development and exacerbation of eczema (Kanda et. al., 2021):

Vitamin D

Low levels of vitamin D have been associated with an increased risk of eczema. Vitamin D deficiency compromises immune regulation and skin barrier function, leading to heightened inflammation and susceptibility to allergic reactions. Supplementation with vitamin D has been shown to improve eczema symptoms by modulating immune responses and promoting skin barrier repair. Work with our team to order labs that identify low Vitamin D levels and then make sure to get out in the sun for at least 15 minutes daily and consider taking a good Vitamin D3/K2 supplement like D-Fender:

Vitamin A

Vitamin A deficiency can disrupt skin barrier integrity and immune function, exacerbating eczema symptoms. Vitamin A plays a crucial role in maintaining epithelial cell differentiation and mucosal immunity. By promoting the expression of anti-inflammatory factors and inhibiting pro-inflammatory mediators, vitamin A supplementation can help alleviate eczema-related inflammation and improve skin barrier function.


Zinc deficiency has been implicated in the pathogenesis of eczema due to its role in immune regulation and skin barrier maintenance. Zinc promotes wound healing, regulates inflammatory responses, and enhances skin integrity. Insufficient zinc levels can compromise immune function, leading to dysregulated inflammatory responses and impaired skin barrier function, thereby exacerbating eczema symptoms.

Omega-3 Fatty Acids

Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have anti-inflammatory properties that can benefit individuals with eczema. Deficiencies in omega-3 fatty acids have been linked to increased inflammatory responses and compromised skin barrier function, contributing to eczema severity. Supplementation with omega-3 fatty acids has been shown to reduce inflammation, improve skin hydration, and alleviate eczema symptoms. Work with our team to order labs that identify low Omega-3 levels and then consider increasing Omega-3 rich foods in your diet and taking a good Omega-3 supplement like Omega Essentials:


Imbalances in gut microbiota, often exacerbated by nutrient deficiencies, have been associated with eczema development. Probiotics, such as Lactobacillus and Bifidobacteria, promote gut microbial diversity and immune regulation, reducing the risk of allergic sensitization and eczema exacerbation. By modulating gut microbiota composition and enhancing immune tolerance, probiotic supplementation can help prevent and manage eczema. Work with our team to order labs that identify low probiotic levels in your gut and then consider taking a good probiotic supplement like Gut Restore:

​Understanding the role of nutrient deficiencies in eczema underscores the importance of maintaining adequate nutrient levels through diet and supplementation to support immune function, skin barrier integrity, and inflammatory regulation, ultimately improving eczema outcomes. If your diet is low in several nutrients, consider taking a good multivitamin like Complete Liquid:

Toxins in Food

Toxins in food, including additives, food coloring, pesticides, and herbicides, can contribute to the development and exacerbation of eczema by increasing the body's toxic burden and triggering inflammatory responses. These substances are often found in conventionally grown produce, processed foods, and animal products, and their accumulation in the body can disrupt immune function and exacerbate skin inflammation. For more detailed information on toxins and their impact on eczema, refer to Root Cause #2: Toxic Burden, where we delve deeper into how environmental toxins can affect overall health and skin conditions like eczema.


Evaluating your nutritional status is an essential step in understanding your overall health and well-being. Poor nutrition can have a significant impact on various aspects of your health, including energy levels, immune function, and skin health.

Evaluate Your Plates

The CleanFOOD plate

Assessing your daily dietary habits is a crucial step in determining if you have poor nutrition. Consider the composition of your meals and snacks—are they rich in whole, nutrient-dense foods like fruits, vegetables, lean proteins, and whole grains? Take note of any deficiencies in essential nutrients and vitamins.

At Cleanbody, we emphasize a balanced approach to nutrition, focusing on incorporating healthy, organic proteins, an abundance of non-starchy vegetables, and small portions of complex carbohydrates and healthy fats. Our goal is to fill your plate with a diverse array of colorful plant-based foods that promote liver detoxification and anti-inflammatory actions in the body. As part of our commitment to reducing inflammation, we work to eliminate or reduce common dietary offenders.

When you join the Cleanbody For Life membership, you gain access to our comprehensive CleanFOOD Plan, featuring a database of 1400 recipes approved in our program. You also gain access to our Cleanbody app, which includes a food journaling system that can help track your eating patterns and identify areas for improvement.

To begin this journey, we recommend booking a consultation with Dr. Fong to undergo a thorough evaluation and kickstart your personalized nutrition plan.

Get Tested For Food Sensitivity & Allergy


Investigating food sensitivities and allergies is a crucial aspect of evaluating poor nutrition. While a food allergy test is typically something you can request from your primary care physician or pediatrician, conventional doctors may not routinely run food sensitivity tests. Recognizing this gap, we offer two comprehensive panels that you can order directly to assess food sensitivities and allergies.

The Food Sensitivity Basic panel evaluates sensitivity to 96 common foods in the Western diet. Sensitivity to certain foods can develop from various health conditions, leading to inflammation and triggering adverse reactions.

For a more comprehensive assessment, we recommend the Food Sensitivity Complete panel, which assesses sensitivity to 209 common foods in the Western diet, as well as food additives like preservatives, artificial sweeteners, emulsifiers, food dyes, and pesticides. These additives can contribute to chronic inflammation and increased intestinal permeability (leaky gut).

Both panels can be ordered directly from our website. Alternatively, you can book a consultation with Dr. Fong to determine whether these tests are suitable for your specific needs and health goals.

Get Tested For Toxic Burden


Exposure to environmental toxins like pesticides and herbicides can have detrimental effects on your health and nutritional status. Consider testing for toxic burden with the Total Tox Burden Test that measure levels of these chemicals in your body. Understanding your toxic load can help identify potential sources of exposure and guide lifestyle changes to minimize their impact on your overall health and nutritional well-being. Alternatively, you can book a consultation with Dr. Fong to determine whether this tests is suitable for your specific needs and health goals.

Identifying and avoiding foods that trigger sensitivities or allergic reactions is crucial for improving your nutritional status and overall well-being. By eliminating these trigger foods from your diet, you can alleviate inflammation, improve gut health, and enhance nutrient absorption. When addressing food sensitivities and allergies, our approach typically involves temporarily eliminating suspect foods from your diet for a duration ranging from three weeks to three months, or until noticeable improvements in symptoms are observed. Subsequently, we strategically reintroduce these foods to assess whether the sensitivities persist or if tolerance has been regained. 


It's crucial to collaborate with a nutritionist or naturopathic doctor when embarking on an elimination diet to ensure that your nutritional needs are met and to prevent potential deficiencies. Working closely with a knowledgeable expert can help you devise a balanced meal plan that compensates for any eliminated foods, ensuring that you receive adequate nutrients to support overall health and well-being throughout the process. Schedule a consultation today to take the first step towards achieving your health and nutrition goals.

Eat Whole, Organic & Non-GMO Foods
