A decrease in sodium intake or an increase in potassium intake reduces blood pressure (BP) in people with essential hypertension. Additional potassium prevents, in sodium-sensitive people and rats, the rise in BP caused by extra sodium chloride. In people with a diastolic BP between 90 and 100 mm Hg, dietary reduction of sodium to 80 mmol/day and dietary increase of potassium to 90 mmol/day caused a fall in BP of 5.1/4.2 and 3.6/3.1 mm Hg, respectively, greater than was observed in the control… 
Effects of high sugar diets on renal fluid, electrolyte and mineral handling in rats: relationship to blood pressure.
Salt and water retention occur early during sugar-induced hypertension due to reduced renal excretion, consistent with some part in the pathogenesis.
Blood Pressure Effects of Sodium Reduction
In this dose–response analysis of sodium reduction in clinical trials, an approximately linear relationship between sodium intake and reduction in both systolic and diastolic BP was identified across the entire range of dietary sodium exposure.
Early lead challenge and subsequent hypertension in Sprague-Dawley rats.
While a high sugar diet alone was associated with elevated SBP, high sugar consumers also challenged with Pb had the highest SBP; previous exposure to Pb can cause subsequent chronic elevations in SBP.
Hypertension and Nutrition
No other chronic medical condition in the United States equals hypertension (HTN) in terms of prevalence and long-term health consequences. HTN will affect the majority of people living in the United
Dietary intake and dietary patterns related to blood pressure
A sample of middle-aged Australians were consuming excessive amounts of salt from convenience foods and staple foods and consumed insufficient dietary potassium from fruits and vegetables, resulting in population blood pressure reduction.
Sodium Excretion and Racial Differences in Ambulatory Blood Pressure Patterns
The results of this study support research that has demonstrated a stronger relation between Na+ handling and casual blood pressure in black subjects and extend these findings to blood pressure while the subject is both awake and asleep.
