Renal potassium physiology: integration of the renal response to dietary potassium depletion

Kidney International, 2018
We summarize the current understanding of the physiology of the renal handling of potassium (K+), and present an integrative view of the renal response to K+ depletion caused by dietary K+ restriction. This renal response involves contributions from different nephron segments, and aims to diminish the rate of excretion of K+ as a result of: decreasing ...

Role of Aldosterone and Dietary Potassium in Potassium Adaptation in the Distal Colon of the Rat

Gastroenterology, 1985
The present experiments were designed to differentiate the effects of aldosterone and chronic potassium loading in the mechanism of colonic potassium adaptation, using a recently described animal model that permits systematic manipulation of aldosterone and dietary potassium.

Serum potassium level and dietary potassium intake as risk factors for stroke

Neurology, 2002
Numerous studies have found that low potassium intake and low serum potassium are associated with increased stroke mortality, but data regarding stroke incidence have been limited. Serum potassium levels, dietary potassium intake, and diuretic use in relation to risk for stroke in a prospectively studied cohort were investigated.The study comprised 5 ...

Dietary Potassium and Hypertension: Epidemiologic Data

Annals of Internal Medicine, 1983
The strong geographic and social class differences in blood pressure may be related to differences in potassium intake or in the ratio of sodium to potassium intake. "Low salt" populations also have high potassium intake. In Japanese villages, populations with similar salt intake but different blood pressures had different potassium intake.

Alterations to potassium fluxes in the heart during chronic dietary potassium depletion

Journal of Molecular and Cellular Cardiology, 1985
Dietary K+ depletion in rabbits causes a loss of cellular K+ from skeletal muscle but not from cardiac muscle, and it has been suggested that this is due to a specific protective mechanism in the heart. Net uptake and efflux of 42K was investigated in the interventricular septum of the rabbit.

Potassium Requirement of Kittens as Affected by Dietary Protein

The Journal of Nutrition, 1982
The dietary potassium requirements of weaning kittens given basal diets containing either a "normal" (33%) or "high" (68%) level of protein were determined. Potassium as KHCO3 was added to give concentrations of 0.1, 0.2, 0.3, and 0.4% for the 33% protein diet and 0.3, 0.4, 0.5, and 0.6% for the 68% protein diet. Excluding the highest concentrations of

DIETARY SODIUM, CALCIUM, AND POTASSIUM, AND BLOOD PRESSURE

American Journal of Epidemiology, 1986
The cross-sectional association of systolic blood pressure with dietary sodium, calcium, and potassium, as estimated from dietary histories, was investigated by multiple regression analysis of data gathered in the Netherlands in the early 1950s in a general health examination of 2,291 middle-aged civil servants and spouses of civil servants.

DIETARY POTASSIUM DEFICIENCY IN THE ELDERLY: A CONTROLLED TRIAL

Age and Ageing, 1975
A controlled cross-over trial of supplementary potassium was conducted in 46 elderly people whose dietary intake of potassium appeared to be no more than 45 mEq per day. Their grip strength and mental function were no better after two weeks' treatment with 48 mEq than when they received placebo tablets.

Dietary Potassium and Blood Pressure

Nephron
Background: With the rising prevalence of hypertension and the limitations of current treatment and prevention strategies, modifying potassium (K+) intake has emerged as a potential new approach to help control blood pressure (BP). While the renal mechanisms behind the detrimental effects of high salt intake on BP are relatively well described, how and

Dietary subacute zinc deficiency and potassium metabolism

Biological Trace Element Research, 1994
In a controlled animal experiment the effects of dietary subacute Zn deficiency on growth, Zn concentration, and tissue 42-K distribution were studied. Growth retardation caused lower body weight because both skeletal and heart muscle showed a reduction in cell mass.
