The newest ionic theory out of blood circulation pressure or other metabolic problems from the Resnick 66 is actually characterized by the next: 1) improved intracellular totally free calcium and smaller intracellular 100 % free magnesium influence the amount of vasoconstriction or vasodilatation 66 ; 2) increased glucose and you will reasonable-density lipoprotein cholesterol levels beliefs improve intracellular calcium and you will/otherwise straight down intracellular magnesium inside the vascular smooth muscles cells 68 ; 3) blood circulation pressure, insulin opposition, and type II all forms of diabetes mellitus was of the enhanced intracellular calcium and you will diminished intracellular magnesium, and therefore every address diet 69 ; 4) diet plus decreases intracellular calcium supplements accounts 70 ; 5) dieting calcium-suppressible hormone such as for instance parathyroid hormone (PTH) and you can 1,twenty-five nutritional D is vasoactive and you will give calcium supplements uptake from inside the vascular smooth muscle tissue muscle and you may cardiac muscle tissue 71 ; 6) the higher the new PTH quantity, the greater amount of the fresh new reduction of BP, as well as the deeper this new loss in PTH and you can step one,25 nutritional D, the greater amount of brand new BP protection 72 ; 7) those with salt-sensitive and painful and you can calcium-sensitive blood pressure keeps increased intracellular calcium PTH and you may 1,twenty-five vitamin D, however, reduced intracellular magnesium 73 ; 8) fat loss calcium supplements reverses irregular calcium indicator and you will lowers BP 74 ; 9) slimming down potassium decrease urinary calcium excretion and step 1,25 nutritional D plasma levels 75 ; and ten) magnesium intake minimizes structure calcium accumulation. 76
To put it briefly salir con transexual, all round effectation of diet plan on BP is dependent on the new online contribution of numerous nourishment into the cytosolic free nutrients like potassium, calcium, and you can magnesium. Steady-county nutrient concentrations have decided of the both the direct ionic consequences into the glucose otherwise calcium supplements as well as the ionic effects toward hormones (PTH, 1,25 supplement D). 72 A discussion of some additional medical aftereffects of various nutrients toward BP try has just advertised regarding Log out of Health-related Blood pressure level. 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).

Numerous meta-analyses 25-twenty-eight declaration a life threatening reduced BP that have potassium supplements (Dining table I). A young meta-research by Cappuccio and you may MacGregor twenty-five of 19 logical products investigating the result off potassium supplementation towards the BP discovered that oral potassium medicine significantly lower one another systolic BP and diastolic BP (5.9 mm Hg and you may 3.cuatro mm Hg, respectively). Another meta-studies off 33 randomized managed samples (RCTs)26 together with noted one to potassium supplements somewhat decreased BP. The brand new BP-decreasing perception are a lot more obvious inside blacks in contrast to whites and you may those individuals sipping a nourishment packed with sodium chloride. Like with the last meta-analyses, the brand new BP impulse is deeper inside hypertensive than just normotensive patients (step 3.5/2.5 mm Hg against 0.97/0.34 mm Hg, respectively), that has been regarding borderline mathematical benefit. An effective meta-investigation out of regarding forty salt examples and 27 potasisum trials because of the Geleijnse et al. twenty-seven also revealed that a lower intake from sodium and increased consumption of potassium are important members towards the reduction regarding blood circulation pressure. Yet not, a more recent meta-analysis of 5 RCTs, conducted by Dickinson and you will associates, 28 reported that potassium supplements resulted in statistically nonsignificant decrease inside one another systolic BP (step 3.9 mm Hg) and you will diastolic BP (step 1.5 mm Hg). It needs to be appreciated one to particular degree that have potassium supplementation was in fact regarding small course and you may provided small numbers of users.
