What this chart is built on

The thyroid needs iodine, selenium, zinc, and tyrosine to make hormones. Hashimoto's autoimmune thyroid is the most common cause โ€” gluten and dairy often trigger it. Address gut health and reduce inflammatory foods.

Why this works

The evidence behind each food choice.

  1. 1Iodine is required to make thyroid hormone โ€” deficiency causes goiter.
  2. 2Selenium converts T4 to active T3 โ€” Brazil nuts cover daily needs in 2 nuts.
  3. 3Hashimoto's autoimmunity often improves on gluten-free diet.
  4. 4Zinc deficiency reduces thyroid hormone production.
  5. 5Cooking deactivates most goitrogens in cruciferous veg โ€” eat cooked freely.

Beyond the food

Habits that multiply your results.

1
Eat 2 Brazil nuts daily โ€” covers selenium
2
Try gluten-free for 90 days if Hashimoto's โ€” measure antibodies
3
Take thyroid medication on empty stomach (1 hour before food)
4
Avoid coffee within 1 hour of medication
5
Test full thyroid panel: TSH, T3, T4, antibodies
6
Get sun for Vitamin D โ€” supports immune balance
