The Same Plate That Supports Blood Pressure Also Matters for Stroke

Deep-research Food-as-Medicine article on stroke, asking whether the same DASH-style plate that supports blood pressure — fruit, vegetables, whole grains, legumes and nuts, low-fat dairy, less sodium, fewer sweetened beverages, and less red and processed meat — is associated with stroke itself. CDC Stroke Facts (Oct 24, 2024) reports more than 795,000 strokes a year in the United States, about 87% of them ischemic, and a risk of a first stroke nearly twice as high for non-Hispanic Black adults as for White adults. The one randomized trial with stroke as its primary outcome tested a kitchen salt swap: in 20,995 high-risk adults in 600 villages in rural China followed a mean of 4.74 years, a salt substitute of 75% sodium chloride and 25% potassium chloride was followed by stroke rates of 29.14 vs. 33.65 events per 1,000 person-years against regular salt (rate ratio 0.86, 95% CI 0.77-0.96; Neal 2021, PMID 34459569), with serious hyperkalemia events not significantly different (3.35 vs. 3.30 per 1,000 person-years). The pattern evidence is observational: higher DASH adherence was associated with relative risk 0.88 for stroke across 12 prospective cohorts with 548,632 participants, 0.90 after publication-bias adjustment (Feng 2018, PMID 30235731); the highest vs. lowest fruit and vegetable intake was associated with relative risk 0.79 across 20 cohorts with 760,629 participants (Hu 2014, PMID 24811336); and higher potassium intake was associated with stroke risk ratio 0.76 in cohort pooling alongside a trial-measured systolic blood-pressure lowering of 3.49 mm Hg (Aburto 2013, PMID 23558164). No supplement is recommended; the potassium and kidney cautions are stated in full. Evidence grade: MODERATE. Educational article from the Buddha Ayurvedic School of Medicine: https://buddha.hospital
