Celiac disease and depressive disorders as nutritional implications related to common factors - A comprehensive review.
Study Goal
The researchers aimed to evaluate the influence of a gluten-free diet (GFD) on major depressive disorder (MDD) symptoms in patients with celiac disease (CD) and assess common nutrient deficiencies in both conditions.
Results Summary
The study found that a GFD can reduce nutritional deficiencies and depressive symptoms in CD patients, with shared nutrient imbalances (e.g., iron, zinc, vitamins B and D) potentially linking CD and MDD. Probiotics and supplements were recommended to mitigate MDD risk.

Celiac disease (CD) is an immune-mediated disease affecting the small intestine. The only treatment strategy for CD is the gluten-free diet (GFD). One of the more common mental disorders in CD patients is major depressive disorder (MDD). The influence of GFD on the occurrence of MDD symptoms in patients with CD will be evaluated. This diet often reduces nutritional deficiencies in these patients and also helps to reduce depressive symptoms. Both disease entities are often dominated by the same deficiencies of nutrients such as iron, zinc, selenium, iodine, or B and D vitamins. Deficiencies of particular components in CD can favor MDD and vice versa. Gluten can adversely affect the mental state of patients without CD. Also, intestinal microbiota may play an important role in the described process. This work aims to comprehensively assess the common factors involved in the pathomechanisms of MDD and CD, with particular emphasis on nutrient imbalances. Given the complexity of both disease entities, and the many common links, more research related to improving mental health in these patients and the implementation of a GFD would need to be conducted, but it appears to be a viable pathway to improving the quality of life and health of people struggling with CD and MDD. Therefore, probiotics, micronutrients, macronutrients, and vitamin supplements are recommended to reduce the risk of MDD, given that they may alleviate the symptoms of both these disease entities. In turn, in patients with MDD, it is worth considering testing for CD.
