  • Goitrogenic compounds

    low

Your move

Decision guide

Consumer tips

  1. 1

    Slice Brussels Sprouts thinly and sauté them to cut cooking time in half compared to roasting.

  2. 2

    Add Bok Choy at the very end of soup cooking to maintain its satisfying crunch.

  3. 3

    If Brussels Sprouts cause bloating, try steaming them instead of roasting, and eat smaller portions to build tolerance.

  4. 4

    Wash Bok Choy thoroughly between the stems where dirt and pesticide residue hide.

  5. 5

    If you take blood thinners, keep your Brussels Sprouts intake consistent day-to-day rather than avoiding them entirely.
