Mediterranean diet linked to reduced stroke risk in massive study.
A two-decade-long investigation has found a significant association between following a Mediterranean diet and lower risk of all types of stroke. The study, published in the journal Neurology Open Access, suggests that adhering to this dietary pattern could potentially reduce stroke risk by up to 25%, with the greatest benefits seen for hemorrhagic strokes.
Researchers from the US and Greece analyzed data from over 105,000 women aged 53 on average, who were followed for an average of 21 years. The women's diet was assessed using a score system, which awarded points for consuming high amounts of olive oil, nuts, seafood, whole grains, and vegetables, as well as moderate amounts of alcohol.
The findings show that those with higher scores, indicating closer adherence to the Mediterranean diet, were 18% less likely to experience a stroke compared to those with lower scores. This association was seen across all types of strokes, including ischemic and hemorrhagic strokes.
While the study does not prove a causal link between the Mediterranean diet and reduced stroke risk, experts welcomed the findings, highlighting the "huge potential" for reducing stroke incidence by improving dietary habits.
The study's lead author, Sophia Wang, noted that the results support the growing body of evidence linking healthy diets to cardiovascular disease prevention. The researchers also highlighted the importance of further studies to confirm these findings and better understand the underlying mechanisms.
Haemorrhagic strokes, which account for a smaller proportion of stroke cases but are often more severe, showed the greatest benefit from Mediterranean diet adherence. This is significant, as fewer large studies have investigated this subtype of stroke.
The Stroke Association chief executive, Juliet Bouverie, praised the study's findings, stating that "nine out of 10 strokes were preventable" and that the results provide valuable insight into reducing stroke risk through dietary changes.
