## In brief

- In the UK, dairy is one of the main sources of iodine, a mineral the body uses to make thyroid hormones.
- Most plant-based dairy alternatives contain very little iodine.
- The available excerpt of the Earth.com report does not give details of the new study it mentions.

## Why it matters

Readers who replace dairy with plant-based milk, yogurt or cheese may lose a key source of iodine, which the thyroid needs to make its hormones.
