Food products worth paying attention to:
- Soy milk, tofu, edamame, soy protein isolate, soy sauce
Soy contains isoflavones (such as genistein), which are phytoestrogens — plant compounds that can:
- Blocks thyroid peroxidase (TPO) , an enzyme necessary for the production of thyroid hormones
- Interferes with the absorption of thyroid medications
- Increased risk of hypothyroidism , especially in people with low iodine intake
This is particularly concerning in the case of:
- People with Hashimoto's thyroiditis
- People taking levothyroxine (wait 4 hours after taking the medication before consuming soy)
🟢 Tip:
Fermented soybeans (e.g., miso, tempeh, natto ) are less problematic in moderation.
Limit your intake of unfermented soybeans if you have thyroid issues.
