The potential modulation of thyroid inflammatory conditions via a gluten-free diet has been suggested after establishing a link between Hashimoto's thyroiditis (HT) and celiac disease. However, the majority of targeted studies in this field do not support the general recommendation of prescribing a gluten-free diet (GFD) for all HT patients. This study aims to analyze data regarding the impact of a GFD supplemented with eicosapentaenoic (EPA) and docosahexaenoic acid (DHA), along with vegetables, on the course of inflammation involving long-chain fatty acid mediators. The study cohort consisted of 39 Caucasian female patients with autoimmune HT. Metabolite separations were performed using a liquid chromatograph with a DAD detector. Absorption peaks were read at 210 nm for resolvin E1, protectin DX, and maresin 1 and at 302 nm for resolvin D1. The introduction of a gluten-free diet completed with omega-3, including EPA and DHA, may contribute to a reduction in the inflammatory state in HT patients. This effect is supported by the elevation in the levels of anti-inflammatory mediators derived from long-chain fatty acids with anti-inflammatory properties but not by eliminating gluten. Significant statistical changes in the levels of all derivatives were observed before and after the implementation of the diet. It is worth noting that this effect was not observed in anti-TPO and anti-TG levels. The induction of anti-inflammatory changes can be achieved by supplementing the diet with EPA, DHA and vegetables with increased anti-inflammatory potential.
