The Study
Whether a Gluten-Free Diet Should Be Recommended in Chronic Autoimmune Thyroiditis or Not?—A 12-Month Follow-Up
This study tried to see if going gluten-free helps people with Hashimoto’s thyroiditis. It found a tiny change in one hormone (TSH) in some women, but nothing big or consistent. It doesn’t prove gluten causes the problem — it just shows a possible link that might be a coincidence.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Some women with an overactive immune system attacking their thyroid took away gluten from their food for a year. Their thyroid hormone levels improved, but their immune markers didn’t change.

Key takeaways
Summary
Based on the study abstract and findings.
- 1The improvement in TSH and fT4 may mean thyroid hormone is absorbed better with a gluten-free diet — not because the immune system calmed down.
- 2But the effect wasn’t strong or consistent across all patients.
- 3TSH dropped significantly (better thyroid function), fT4 went up a little, but anti-TPO and anti-TG antibodies stayed the same in both gluten-free and control groups.
