Dietary amino acids and the risk of hypertension in a Dutch older population: The Rotterdam Study

Background: Inverse associations between dietary protein and hypertension have been reported, which may be attributed to specific amino acids. Objective: We examined whether the intake of glutamic acid, arginine, cysteine, lysine, or tyrosine was associated with blood pressure (BP) levels (n = 3086) and incident hypertension (n = 1810) in the Rotterdam Study. Design: We calculated BP levels in quartiles of amino acid intake as a percentage of total protein intake (% of protein) with adjust
