Study Links Mediterranean Diet to 18% Lower Stroke Risk in Women

Women adhering closely to a Mediterranean diet had an 18% lower risk of stroke overall, including a 25% reduction in hemorrhagic stroke, in a study of over 105,000 participants.

  • Published February 4, 2026, the study in Neurology Open Access found women in the California Teachers Study with strongest Mediterranean-style diet adherence were 18% less likely to have any stroke.
  • Because stroke risk climbs after menopause, researchers investigated the Mediterranean diet as a modifiable factor.
  • Using baseline diet questionnaires, investigators followed 105,614 women from the California Teachers Study, with an average follow-up of 21 years during which 4,083 strokes occurred.
  • Study authors said adhering to a Mediterranean-style diet could lessen women's stroke risk, highlighting its importance as stroke affects 1 in 5 U.S. women ages 55–75, per CDC data.
  • Looking forward, authors called for further studies to confirm the unexpected 25% risk reduction for hemorrhagic stroke and noted study limitations of self-reported diet and no tracking over time.
