Vegan diets may be associated with a higher risk of ischemic stroke compared to non-vegan diets, although the finding was not statistically significant.
One study suggested a potential trend toward higher ischemic stroke risk in vegans, but it was not statistically significant. Ensure you are supplementing with B12 and Omega-3s (EPA/DHA) to mitigate any potential risks associated with nutrient deficiencies.
LimitedQualifiesLOW confidence
One study suggested that vegans were at greater risk of ischemic stroke compared to individuals who consumed animal products (HR, 1.54; 95% CI, 0.95–2.48).
Why this rating
Based on a single study with wide confidence intervals; evidence quality is low.
