In SR people we observed zero relationships anywhere between urinary Na + excretion and SBP

In the current study, using data from the DASH–Sodium trial, during screening when participants are consuming their normal dietary intake, we report a slope increment of an elevation in SBP of approximately 3 mmHg across the urinary Na + excretion range of 2–5 g/day in SS, but not SR participants. However, when assessed across the full range of observed urinary Na + excretion values we did not observe a positive correlation between SBP and urinary Na + excretion in either SS or SR participants. Significantly, despite urinary K + excretion of <1 g K + /day associating with higher SBP in SS and SR participants further increments in urinary K + excretion did not correlate with a reduction in SBP in either participant group. Furthermore, at baseline screening we did not observe a correlation between the urinary Na + :K + excretion ratio irrespective of the salt sensitivity of blood pressure. Following the DASH dietary intervention we observed no correlation between a urinary Na + :K + ratio and SBP in either SS or SR participants. As such our data, from the DASH–Sodium Trial, in US participants at both baseline screening and following a highly controlled dietary intervention does not support the hypothesis that a reduced urinary Na + :K + ratio will be beneficial in population level blood pressure reduction or support the proposal for a urinary Na + :K + molar ratio of <1 to lower blood pressure.

In a randomized controlled demo used from inside the free living non-fat reduction managed players that have a suggest SBP regarding 132 mmHg and maybe not bringing blood pressure decreasing treatment, K + consumption is increased by the fat loss consumption (via fresh fruit and you will veggie intake) otherwise head K + medicine

In contrast to the brand new Sheer , INTERSALT , and you may INTERMAP education, you to dependent a society height self-confident connection between urinary Na + removal and blood pressure, brand new Dash–Salt Demonstration permits the fresh new business of your salt susceptibility out-of bloodstream tension when you look at the demo participants. However, for the SS participants i seen a hill increment off a growth from inside the SBP of just one.3 mmHg for every single step one g escalation in urinary Na + removal over the excretion set of 3–5 g Na + /day which is within typical mediocre directory of every single day Na + intake in the usa . On the other hand, whenever assessed across the whole list of noticed urinary Na + excretion, we observed zero association ranging from urinary Na + removal and you may SBP either in SS otherwise SR players. I speculate that it difference between an optimistic relationship ranging from SBP and urinary Na + excretion for the requested range of dietary Na + removal away from 3–5 grams/big date without association over the complete list of philosophy reflects the perception away from numerous members on the Dashboard–Salt study exhibiting large levels of urinary Na + excretion, more than 5 g/go out, and you can comparatively reasonable blood circulation pressure. Rather, the importance gotten within investigation getting a boost in SBP contained in this 3–5 grams/big date Na + removal is comparable to you to acquired regarding Absolute research which stated a positive hill increment off a-1.eight mmHg boost in SBP per step one grams escalation in urinary Na + removal along the same range of Na + excretion opinions . The essential difference between brand new seen upsurge in SBP in response to raised urinary Na + removal ranging from Dash-Sodium and you can Absolute ple dimensions and racial backgrounds of people and you may (2) the possibility differences in ways to determine urine articles off twenty-four-h pee collection versus an evaluation from a single morning room pee shot from the Dashboard-Salt in the place of Sheer Studies https://datingranking.net/pl/milfaholic-recenzja/ respectively. Our analysis help advice to help you maximum losing weight Na + intake [5, 24] and you may advise that smaller losing weight salt intake might only lower SBP during the SS people.

The influence of K + intake on blood pressure remains controversial, with conflicting data emerging from multiple clinical studies . In this study increased K + intake up to 40 mmol/day had no impact on blood pressure [22, 26]. A separate randomized placebo-controlled crossover trial was conducted in participants who have never received antihypertensive medication with mildly elevated blood pressure . Participants were maintained on their normal diet and received K + at 64 mmol/day for a 4-week period as either potassium chloride or bicarbonate-in this study there was no effect of K + supplementation on office blood pressure . In contrast in a randomized placebo-controlled, crossover study, in which untreated patients with a mean SBP of 145 mmHg blood pressure received 4 weeks of supplemental K + at 3 g/day and a diet relatively low in Na + reported a reduction in SBP of 3.9 mmHg. Beyond the highly controlled trials discussed above the PURE study reports that for each increment of 1 g/day of urinary K + excretion there is a reduction of 0.75 mmHg in SBP across the excretion range of <1.25 to 3 g K + /day . In the DASH–Sodium data, we observed an elevation in SBP in both SS and SR participants when urinary K + excretion was below 1 g/day. However, we did not observe any correlation between urinary K + excretion and SBP or an impact of urinary K + excretion on SBP over the range of <1 to >3 g K + excretion per day. We speculate that discrepancy between the PURE study data and our own analysis of the DASH-Sodium data may reflect the difference in SBP response to urinary K + excretion reported in PURE between Chinese and non-Chinese participants. Chinese participants exhibited a large reduction in SBP with increased urinary K + excretion versus a smaller SBP effect in participants from the rest of the world. As the DASH-Sodium trial did not contain Chinese participants this may have influenced the outcome.
