Elimination of ultra-processed foods and refined carbohydrates reduces systemic inflammation and improves immune function in individuals with autoimmune conditions.

Study: Ultra‐Processed Foods Reduction Enhances Clinical Outcomes and Dietary Profiles in Patients With Gingivitis: Results From a Randomised Controlled Trial

Removing junk food helped people with gum inflammation get better, which suggests that cutting out processed foods might also help reduce body-wide inflammation in other diseases like autoimmune disorders.

Study: Decreased ultra-processed food consumption as a mediator for lowering cardiovascular risk after a lifestyle program in pediatric obesity: a randomized clinical trial

This study found that when kids ate fewer ultra-processed foods, their heart health got better—likely because those foods cause body-wide inflammation. Since inflammation also worsens autoimmune diseases, cutting them out probably helps there too.

Study: Ultra‐Processed Foods and Markers of Systemic Inflammation in Children

This study found that kids who ate more ultra-processed foods had higher levels of body chemicals linked to inflammation. So, cutting out those foods might help reduce inflammation, which is important for people with autoimmune diseases.

Study: Ultra-processed foods: increasing the risk of inflammation and immune dysregulation?

This study shows that ultra-processed foods can mess up your gut and immune system, making inflammation worse. So, if you stop eating them, your body might calm down and work better — especially if you have an autoimmune disease.
