Key result
Body mass index and sodium excretion were positively correlated with blood pressure, whereas magnesium and animal protein markers were inversely correlated with blood pressure.

Do dietary factors correlate with blood pressure in adults aged 50-54 years?
This large multinational cross-sectional study demonstrates that higher sodium intake and BMI are associated with higher blood pressure, while magnesium and animal protein intake may have beneficial effects.
Yamori et al. (1990) conducted a cross-sectional in Blood pressure and cardiovascular diseases. Dietary factors (sodium, magnesium, animal protein) and BMI was evaluated on Systolic and diastolic blood pressure. Body mass index and sodium excretion were positively correlated with blood pressure, whereas magnesium and animal protein markers were inversely correlated with blood pressure.
