Level 5 - mechanism / opinion, no new human data
Narrative review of human literature without systematic review or meta-analysis methodology

What was done
The authors searched PubMed (MEDLINE) and Google Scholar using terms related to hypothyroidism, Hashimoto's thyroiditis, and gluten. They reviewed human studies evaluating the effects of gluten intake or a gluten-free diet on thyroid autoimmunity in patients with Hashimoto's thyroiditis with or without coexisting celiac disease.
What was found
The abstract reports no quantitative metrics or numerical findings. It notes that only a few studies suggest potential benefits of a gluten-free diet in Hashimoto's thyroiditis without celiac disease, while gluten exclusion may risk nutritional deficiencies from low-quality gluten-free substitute products. The authors concluded the available literature does not support gluten elimination for Hashimoto's thyroiditis.
Why it matters
Despite widespread clinical and popular interest in dietary gluten elimination for autoimmune conditions, this review highlights the lack of robust evidence supporting a gluten-free diet for Hashimoto's thyroiditis in the absence of celiac disease.
Limits
The paper is a narrative review that does not report study selection metrics, sample sizes, or quantitative meta-analytic pooling. The underlying primary evidence base cited is small, ambiguous, and subject to substantial methodological limitations.
