Indication: Blood pressure
Source: Arch Intern Med, January 9, 2006;166(1):79-87.
Research: Researchers conducted a cross-sectional epidemiological study on 4680 people, aged 40 to 59 years, from four countries. Systolic and diastolic blood pressure was measured eight times during four visits. Dietary intake based on 24-hour dietary recalls was recorded four times. Information on dietary supplements was also noted. Two 24-hour urine samples were obtained per person.
Results: There was a significant inverse relationship between vegetable protein intake and blood pressure. After adjusting for confounders, blood pressure differences associated with higher vegetable protein intake of 2.8% kilocalories were -2.14 mm Hg systolic and -1.35 mm Hg diastolic; after further adjustment for height and weight, these differences were -1.11 mm Hg systolic and -0.71 mm Hg diastolic. For animal protein intake, significant positive blood pressure differences did not persist after adjusting for height and weight. For total protein intake (which had a significant interaction with sex), there was no significant association with blood pressure in women, nor in men after adjusting for dietary confounders. There were significant differences in the amino acid content of the diets of persons with high vegetable and low animal protein intake compared to the diets of persons with low vegetable and high animal protein intake.
