Diet rich in soy, fermented foods may lower postpartum depression

Soy and fermented food diet may lower postpartum depression by boosting gut health.

Why it matters

  • Postpartum depression affects 10-20% of mothers globally.
  • Dietary interventions could offer non-drug support for mental health.

By the numbers

  • Study involved 344 mothers; 14% had high depression risk.

The big picture

  • Soy-fermented food diet linked to lower depression and healthier gut bacteria.
  • Supports gut-brain axis in maternal mental health.

Caveats

  • Study can't prove causation; dietary intake was self-reported.
  • Results may not apply to non-Japanese diets.

What’s next

  • Further studies planned to test dietary interventions for postpartum mental health.
