After 12 weeks of eating a gluten-free, Mediterranean, or combined diet, women with Hashimoto's thyroiditis showed lower levels of thyroid antibodies, but the reduction was not greater than what was seen in women who didn't change their diet.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether dietary interventions consistently reduce anti-TPO or anti-Tg antibodies in Hashimoto's thyroiditis across populations, accounting for baseline antibody levels and dietary adherence.
A systematic review and meta-analysis of at least 12 RCTs with 50+ participants each, comparing gluten-free, Mediterranean, or combined diets to control diets in Hashimoto's thyroiditis, measuring anti-TPO and anti-Tg at baseline and 3, 6, and 12 months.
Whether specific dietary patterns cause a clinically meaningful reduction in thyroid autoantibodies compared to placebo in Hashimoto's thyroiditis.
A double-blind RCT with 200 women aged 18–65 with Hashimoto's thyroiditis and elevated anti-TPO (>500 IU/mL), randomized to Mediterranean, gluten-free, combined, or placebo diet (standard Western diet), for 6 months, with antibody levels measured monthly and adjusted for selenium and iodine intake.
Whether long-term adherence to these diets predicts a sustained decline in thyroid autoantibody titers over 3–5 years in Hashimoto's thyroiditis.
A prospective cohort study following 500 women with Hashimoto's thyroiditis for 5 years, assessing dietary patterns every 6 months via FFQ and measuring anti-TPO and anti-Tg annually, adjusting for medication, BMI, and environmental exposures.
Whether women with Hashimoto's thyroiditis who have low antibody titers (<100 IU/mL) are more likely to have followed a gluten-free or Mediterranean diet for ≥6 months compared to those with high titers (>1000 IU/mL).
A case-control study comparing 100 women with Hashimoto's thyroiditis and anti-TPO <100 IU/mL to 100 with anti-TPO >1000 IU/mL, matched for age and disease duration, assessing past 12-month dietary patterns via detailed food records.
Whether current adherence to gluten-free or Mediterranean diets correlates with lower anti-TPO or anti-Tg levels in Hashimoto's thyroiditis at a single point in time.
A cross-sectional survey of 1000 women with Hashimoto's thyroiditis measuring current anti-TPO and anti-Tg levels alongside a single dietary assessment via FFQ to estimate adherence to gluten-free or Mediterranean patterns.
