No evidence supports potassium-based inter- ventions for CVD reduction26 ; no dietary interventions of increased potassium consumption alone in stroke survivors were identified. Overnutrition is addressed in Section 4.5, Obesity. Recommendation-Specific Supportive Text 1. The interventional arms of the PREDIMED trial (Prevenci n con Dieta Mediterr nea), compris- ing the Mediterranean diet with either supple- mental extravirgin olive oil or tree nuts (Table 4) compared with a low-fat diet,95 provide evidence of a reduction in stroke events in individuals with high cardiovascular risk (HR, 0.60 [95% CI, The primary end point (MI, stroke. or cardiovas- cular death) identified adjusted HRs of 0.72 (95% CI, 0.54 0.95) for the Mediterranean diet with olive oil supplementation and 0.69 (95% CI, 0.53 0.91) with nut supplementation compared with the control diet. Evidence in secondary pre- vention is drawn from the Lyon Diet Heart trial of the Mediterranean diet with supplemental canola compared with a usual post-MI prudent diet, producing low-quality evidence of reduced CVD mortality and total mortality (adjusted HR, 0.21 0.92], respectively) in a coronary heart One study in first stroke and matched control cases108 shows each unit (1 of 55) in MedDietScore is associated with a 17% lower likelihood of ischemic stroke in participants without hypercholesterolemia (95% CI, 0.72 0.96) and 10% lower likelihood in par- ticipants with hypercholesterolemia (95% CI, 0.81 0.99). 2.
