Dietary sodium targets were 80mmol/day men, 70mmol/day women. Low sodium foods were provided Participants were then randomised into one of 4 groups: Group 1: low sodium, with 1g acid Group 2: added sodium (participants consumed 80mmol/day sodium Blood pressure (seated after at least 5 min rest) 66 (n=30 females, n= 36 Breakdown not shown for different oils 6 weeks Females: Normal sodium period: 150 + 45 mmol/24hr Low sodium period: 77 + 33 mmol/24hr Males: Normal sodium period: 162 + 49 mmol/24hr Low sodium period: 106 + 49 mmol/24hr Females: SBP: Normal sodium period (pre): 118 + 14mmHg Normal sodium period (post): 125 + 17mmHg Low sodium period (pre): 121 + 12mmHg Low sodium period (post): 118 + 9mmHg DBP: Normal sodium period (pre): 68 + 9mmHg Normal sodium period (post): 72 + Low sodium period (pre): 68 + 9mmHg
