Tea is rich in polyphenols, which have activities consistent with blood pressure-lowering potential. The effects of long-term regular ingestion of tea on blood pressure remain uncertain. We investigated the relationships of tea intake and a biomarker of exposure to tea-derived polyphenols (4-O-methylgallic acid) with blood pressure in a cross-sectional study of 218 women > 70 y old. Clinic blood pressures were measured and tea intake was assessed using a 24-h dietary recall; 4-O-methylgallic acid was measured for the same period in a 24-h urine sample. Mean (95% CI) daily tea intake was 525 (475, 600) mL. Mean systolic and diastolic blood pressures were 138.1 (135.6, 140.6) and 73.5 (72.1, 74.9) mm Hg. Higher tea intake and higher 4-O-methylgallic acid excretion were associated with significantly lower systolic (P = 0.002 and P = 0.040, respectively) and diastolic (P = 0.027 and P < 0.001, respectively) blood pressures. A 250 mL/d (1 cup) increase in tea intake was associated with a 2.2 (0.8, 3.6) mm Hg lower systolic blood pressure and a 0.9 (0.1, 1.7) mm Hg lower diastolic blood pressure. The observed associations for both tea intake and 4-O-methylgallic acid are consistent with the hypothesis that long-term regular ingestion of tea may have a favorable effect on blood pressure in older women.
