New ionic hypothesis away from blood pressure or any other metabolic issues by the Resnick 66 is actually described as the following: 1) enhanced intracellular free calcium and you can shorter intracellular free magnesium determine brand new number of vasoconstriction or vasodilatation 66 ; 2) raised sugar and you can lower-density lipoprotein cholesterol values raise intracellular calcium supplements and/or lower intracellular magnesium inside the vascular smooth muscle mass tissue 68 ; 3) hypertension, insulin opposition, and kind II diabetic issues mellitus is actually with the increased intracellular calcium and you can decreased intracellular magnesium, which all answer dieting 69 ; 4) losing weight also reduces intracellular calcium membership 70 ; 5) losing weight calcium-suppressible hormone such parathyroid hormone (PTH) and you will step 1,twenty-five nutritional D was vasoactive and you will promote calcium use from inside the vascular smooth muscle muscle and cardiac muscle 71 ; 6) the greater new PTH amount, the more new reduced amount of BP, additionally the deeper the newest loss in PTH and you will step 1,twenty five vitamin D, the greater number of brand new BP avoidance 72 ; 7) those with salt-delicate and you can calcium-painful and sensitive blood pressure levels enjoys raised intracellular calcium supplements PTH and step 1,25 vitamin D, but low intracellular magnesium 73 ; 8) weight loss calcium reverses abnormal calcium supplements indices and you will reduces BP 74 ; 9) fat reduction potassium decreases urinary calcium supplements excretion and you will step 1,twenty-five vitamin D plasma membership 75 ; and 10) magnesium consumption reduces muscle calcium supplements accumulation. 76
In a nutshell, the overall aftereffect of diet plan toward BP hinges on new online contribution of various nutrition for the cytosolic free nutrition like potassium, calcium, and magnesium. Steady-county nutrient levels decided because of the both the head ionic effects toward sugar or calcium supplements plus the ionic effects with the hormone (PTH, step one,25 supplement D). 72 A discussion of some even more logical negative effects of certain nutrition towards BP is actually recently claimed regarding the Diary away from Health-related Blood pressure levels. 77
Conclusions
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 25-twenty-eight report a critical reduction in BP having potassium supplementation (Dining table I). An early on meta-studies because of the Cappuccio and you can MacGregor 25 from 19 clinical products examining the result regarding potassium supplements to your BP discovered that dental potassium medicine somewhat reduced both systolic BP and you will diastolic BP (5.nine mm Hg and you will step three.4 mm Hg, respectively). Some other meta-study regarding 33 randomized controlled samples (RCTs)twenty six as well as reported you to potassium supplementation rather lowered BP. The latest BP-decreasing effect are far more pronounced within the blacks in contrast to whites and the individuals drinking a diet filled with sodium chloride. As with the earlier meta-analyses, the brand new BP response are better in the hypertensive than simply normotensive patients (step 3.5/dos.5 mm Hg versus 0.97/0.34 mm Hg, respectively), that has been of borderline statistical relevance. A beneficial meta-research out-of away from 40 salt products and you will twenty seven potasisum examples because of the Geleijnse mais aussi al. twenty-seven together with showed that a lesser intake of sodium and you will improved consumption off potassium are very important contributors to the protection from hypertension. But not, a more recent meta-analysis of five RCTs, used by Dickinson and you can associates, avere uno sguardo a questo sito twenty-eight reported that potassium supplementation led to mathematically nonsignificant reductions inside the one another systolic BP (3.nine mm Hg) and you may diastolic BP (1.5 mm Hg). It should be recalled that certain studies that have potassium supplementation was out of small duration and you may incorporated short numbers of participants.
