How can genetic markers help determine the best diet for autoimmune skin diseases?

In my role as a nutritionist and dietician, I'm often asked what the role of diet and genetics is in treating autoimmune skin disorders. It is important to understand not only how the genetics can affect our responses to foods and nutrients, but also the needs of the human body. This discussion will explore the role of genetic markers when determining an ideal diet for skin autoimmune conditions. We'll also discuss how to start, examples of relevant genetic markers and other useful tips.

How to identify genetic markers for autoimmune skin conditions

Psoriasis, eczema and other chronic skin diseases are caused by an immune system overreacting to the skin. Both environmental and genetic influences are believed to play a significant role in the development of these skin conditions. Some studies found links between susceptibility and autoimmune disorders. Genetic markers are important in guiding dietary management of these conditions.

Knowing your genetic make-up can allow you to identify triggers and food sensitivities which may worsen your condition. This will help create a personalized diet plan. It's also important to remember that, while genetic data is beneficial, it doesn't provide a cure-all. The most successful approach is a comprehensive one that includes lifestyle changes and medical treatment.

Important Points for Getting Started

It's important to speak with a health care provider who is both knowledgeable about nutrition and genetics before making dietary changes based on your genetic markers. The results of genetic testing are complex and should be considered in the context your health and lifestyle as well as personal and family history.

While there is promising research on this topic, many unknowns remain about complex interactions between diet and genetics in autoimmune diseases. As part of an overall treatment plan, it is important to consider dietary modifications based on the genetic markers.

More Tips and Suggestions

A holistic approach should also include fruits, vegetables, healthy fats, and lean protein. These foods contain essential nutrients to support skin and immune health. Drinking plenty of water and avoiding processed food, as well as maintaining a healthy body weight, can help to manage symptoms.

What works for you may not be the best for someone else. To find out what is best for you, it's important to make regular adjustments and follow ups to your diet plan.


Understanding your genetic make-up can give you valuable insight into the way your body may respond to different diets, and could help manage autoimmune skin disorders. It should, however, be part of an overall treatment plan which includes lifestyle changes and medical treatments. With professional advice and careful consideration, genetic marker-based dietary modifications can be a powerful tool in the management of these conditions.
