Brand new ionic theory of blood pressure and other metabolic issues by Resnick 66 is described as the second: 1) increased intracellular totally free calcium and you will smaller intracellular totally free magnesium dictate new level of vasoconstriction or vasodilatation 66 ; 2) increased glucose and you can low-density lipoprotein cholesterol levels values increase intracellular calcium and you may/otherwise down intracellular magnesium in the vascular smooth muscle muscle 68 ; 3) hypertension, insulin resistance, and kind II diabetic issues mellitus are on the increased intracellular calcium supplements and you can reduced intracellular magnesium, and that all respond to fat loss 69 ; 4) diet as well as reduces intracellular calcium membership 70 ; 5) dieting calcium supplements-suppressible hormone such as for instance parathyroid hormone (PTH) and you can step 1,twenty-five vitamin D is vasoactive and you will offer calcium consumption in vascular simple muscle tissue and cardiac muscle tissue 71 ; 6) the higher the newest PTH concentration, the more the decrease in BP, additionally the greater the brand new reduction in PTH and 1,twenty-five vitamin D, more brand new BP cures 72 ; 7) individuals with salt-sensitive and you will calcium-delicate blood circulation pressure possess elevated intracellular calcium supplements PTH and you can 1,twenty-five supplement D, but lower intracellular magnesium 73 ; 8) fat reduction calcium supplements reverses irregular calcium supplements indices and reduces BP 74 ; 9) weight-loss potassium reduces urinary calcium supplements excretion and you can step one,25 vitamin D plasma membership 75 ; and you may ten) magnesium consumption decrease tissues calcium accumulation. 76
To put it briefly, the overall aftereffect of eating plan with the BP relies on the newest net contribution of numerous diet to your cytosolic totally free minerals like potassium, calcium supplements, and you will magnesium. Steady-condition nutrient concentrations decided by the the lead ionic effects toward sugar or calcium therefore the ionic outcomes with the hormonal (PTH, 1,twenty five supplement D). 72 A discussion of some a lot more health-related aftereffects of some nutrients for the BP is has just advertised about Journal of Systematic Blood pressure levels. 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).

Several meta-analyses twenty five-twenty eight statement a significant lack of BP with potassium supplementation (Dining table We). A young meta-data of the Cappuccio and you may MacGregor twenty five out of 19 clinical products investigating the end result regarding potassium supplementation to the BP found that dental potassium capsules significantly lowered each sitio de citas para personas travesti other systolic BP and you will diastolic BP (5.nine mm Hg and you may step 3.4 mm Hg, respectively). Some other meta-data off 33 randomized managed trials (RCTs)twenty six also recorded one to potassium supplementation rather paid down BP. This new BP-reducing effect is actually far more obvious in the blacks compared with whites and you may those people drinking a nutrition stuffed with sodium chloride. As with the previous meta-analyses, brand new BP effect is greater into the hypertensive than just normotensive people (step three.5/dos.5 mm Hg vs 0.97/0.34 mm Hg, respectively), that has been out-of borderline statistical value. An effective meta-studies off regarding forty sodium samples and twenty seven potasisum samples from the Geleijnse ainsi que al. twenty-seven as well as revealed that a reduced intake out-of sodium and increased consumption away from potassium are essential contributors into the protection out of blood circulation pressure. However, a more recent meta-research of 5 RCTs, used because of the Dickinson and you will associates, 28 reported that potassium supplements resulted in statistically nonsignificant decrease from inside the one another systolic BP (3.9 mm Hg) and you will diastolic BP (step one.5 mm Hg). It needs to be remembered one some knowledge with potassium supplements was away from quick duration and integrated small amounts of people.
