This new ionic theory away from hypertension and other metabolic issues of the Resnick 66 are described as another: 1) improved intracellular totally free calcium supplements and you can faster intracellular free magnesium dictate the fresh new amount of vasoconstriction otherwise vasodilatation 66 ; 2) elevated glucose and you may lower-density lipoprotein cholesterol levels thinking increase intracellular calcium supplements and you will/otherwise straight down intracellular magnesium inside vascular simple muscle tissue 68 ; 3) blood circulation pressure, insulin opposition, and kind II all forms of diabetes mellitus is actually from the enhanced intracellular calcium and you can diminished intracellular magnesium, which all respond to weightloss 69 ; 4) losing weight including decrease intracellular calcium levels 70 ; 5) diet calcium-suppressible hormones such as parathyroid hormones (PTH) and you can step one,twenty five supplement D try vasoactive and you will promote calcium supplements use into the vascular simple strength tissues and you may cardiac muscle mass 71 ; 6) the greater brand new PTH focus, the greater the latest reduced amount of BP, in addition to greater the reduced PTH and you can 1,twenty-five vitamin D, the greater brand new BP cures 72 ; 7) those with sodium-sensitive and painful and calcium supplements-delicate blood pressure level possess increased intracellular calcium supplements PTH and you may 1,25 supplement D, but lower intracellular magnesium 73 ; 8) weight reduction calcium supplements reverses unusual calcium supplements indicator and you may lowers BP 74 ; 9) fat loss potassium decreases urinary calcium removal and you will step one,twenty five vitamin D plasma membership 75 ; and ten) magnesium consumption reduces tissue calcium accumulation. 76
Basically, the general aftereffect of eating plan on BP is dependent upon the fresh web sum of numerous diet toward cytosolic 100 % free vitamins such potassium, calcium, and you may magnesium. Steady-state mineral concentrations have decided by both lead ionic outcomes towards glucose otherwise calcium supplements together with ionic outcomes to your hormonal (PTH, 1,twenty five vitamin D). 72 A discussion of some extra scientific effects of certain nutrition for the BP is has just stated in the Log from Health-related Blood circulation pressure. 77
The average US dietary intake of potassium is 45 mEq/d with a potassium-to-sodium ratio of <1:2. 78 This is less than the recommended intake of 4700 mg/d (121 mEq/d) of potassium, with a potassium/sodium ratio of >5:1. Low potassium intake in the United States is considered a contributor to the prevalence of hypertension. 27 Therefore, if Americans were able to increase their potassium intake alone, the number of adults with known hypertension might decrease. As data from TOHP, 35 PREMIER, 79 and the Trial of Preventing Hypertension (TROPHY) 80 indicate, lifestyle changes such as weight loss, salt restriction, increased exercise, and dietary changes may prevent the progression to hypertension. The results of the DASH studies further indicate that a diet rich in fruits and vegetables is important for the prevention of hypertension and major public health problems such as coronary heart disease and stroke. An increase in potassium with a decrease in sodium is probably the most important dietary choice (after weight loss) that should be implemented to reduce CVD. Unfortunately, the population that could most benefit from increased potassium, magnesium, and calcium in the diet may have the least access to these more expensive food types (fruits and vegetables).

Suggest systolic and diastolic blood pressure levels on standard and you can throughout for each intervention month, considering diet, to possess 379 patients which have over groups of weekly blood pressure level measurements. Reprinted having permission out of Appel et al. 10
Multiple meta-analyses twenty-five-twenty-eight report a serious loss in BP that have potassium supplementation (Table We). An early on meta-analysis because of the Cappuccio and you may MacGregor twenty five out-of 19 medical examples examining the effect off potassium supplements into BP unearthed that oral potassium medications notably lower one another systolic BP and you may diastolic BP (5.nine mm Hg and step 3.cuatro mm Hg, respectively). Various other meta-investigation out-of 33 randomized regulated trials (RCTs)twenty six in addition to documented you to potassium supplementation notably decreased BP. Brand new BP-reducing effect is a whole lot more pronounced for the blacks weighed against whites and those consuming a nutrients high in sodium chloride. Just as in the last meta-analyses, the latest BP effect is actually deeper inside the hypertensive than just normotensive customers (3.5/dos.5 mm Hg against 0.97/0.34 mm Hg, respectively), that was away from borderline statistical benefits. Good meta-study europÃ¤ische Singles away from regarding forty salt samples and you will twenty-seven potasisum examples because of the Geleijnse ainsi que al. twenty seven in addition to showed that a lower life expectancy intake away from salt and increased intake out-of potassium are essential contributors on prevention of blood pressure. However, a more recent meta-research of five RCTs, used from the Dickinson and lovers, twenty-eight reported that potassium supplementation triggered statistically nonsignificant decreases in the both systolic BP (step three.nine mm Hg) and you may diastolic BP (1.5 mm Hg). It should be appreciated you to certain knowledge that have potassium supplementation have been regarding small years and you will provided brief amounts of participants.
