Stroke (vegan-specific risk)
In the UK EPIC-Oxford cohort, vegetarians (including vegans) had higher rates of total and haemorrhagic stroke than meat eaters, but a meta-analysis of prospective cohorts found no clear overall association between vegetarian diets and stroke, and Taiwanese cohorts found lower stroke risk in vegetarians. Vegan-specific estimates rest on few cases and are imprecise. Proposed explanations, such as low vitamin B12 with raised homocysteine or low LDL cholesterol, remain untested hypotheses. No claim reaches moderate certainty because all of the evidence is observational, the cohorts disagree with one another, and the vegan subgroups are small.
