A lower-than-recommended potassium intake is a well-established risk factor for increased blood pressure. Although the Japanese diet is associated with higher sodium intake and lower potassium intake, few studies have examined the source foods quantitatively. Studies on dietary patterns in association with potassium intake will be useful to provide dietary advice to increase potassium intake. Twenty-four-hour (hr) dietary recall data and 24-hr urinary potassium excretion data from Japanese participants (574 men and 571 women) in the International Study of Macro/Micronutrients and Blood Pressure (INTERMAP) were used to calculate food sources of potassium and compare food consumption patterns among quartiles of participants categorized according to 24-hr urinary potassium excretion per unit of body weight (UK/BW). The average potassium intake was 2791 mg/day per participant, and the major sources were vegetables and fruits (1262 mg/day), fish (333 mg/day), coffee and tea (206 mg/day), and milk and dairy products (200 mg/day). Participants in the higher UK/BW quartile consumed significantly more vegetables and fruits, fish, and milk and dairy products, and ate less rice and noodles. Conclusion: Advice to increase the intake of vegetables and fruits, fish, and milk may be useful to increase potassium intake in Japan.

Abstract Background High blood pressure or hypertension is well recognized as an important modifiable risk factor for cardiovascular diseases. Several studies had indicated potassium intake has a blood pressure lowering effect. This study aimed to estimate potassium intake via 24-h urinary potassium excretion and to determine the association between potassium intake and blood pressure among adults in Malaysia. Methods Data for 424 respondents in this study were drawn from MyCoSS, a nationwide cross- sectional study conducted among Malaysians who were 18 years and above. Respondents were recruited using stratified cluster sampling, covering urban and rural areas in each state in Malaysia. Data collection was undertaken from October 2017 until March 2018. A single urine sample was collected over 24 h for quantification of potassium excreted. Information on socio-demography and medical history of the respondents were collected by interviewer-administered questionnaires. Anthropometric measurements were measured using validated equipment. BMI was estimated using measured body weight and height. Digital blood pressure monitor (Omron HBP-1300) was used to measure blood pressure. Descriptive statistics, analysis of variance (ANOVA), and multivariable linear regression were used to analyze the data in SPSS Version 21. Results Mean 24-h urinary potassium excretion for the 424 respondents was 37 mmol (95% CI 36, 38). Gender and ethnicity showed statistically significant associations with 24-h urinary potassium excretion. However, potassium excretion was not significantly associated with blood pressure in this study. Conclusion Potassium intake is very low among the adults in Malaysia. Therefore, further education and promotional campaigns regarding daily consumption of potassium-rich diet and its benefits to health need to be tailored for the Malaysian adult population.

Abstract Background: Excessive sodium (Na) intake and low potassium (K) intake are associated with adverse cardiovascular health outcomes. Morocco lacks data on actual Na and K intake in adults. The aim of this study was to estimate the mean intake of Na and K in a Moroccan population of adults using the 24-h urinary excretion and to examine their association with blood pressure (BP). Methods: A total of 371 adults, who participated in the urinary validation sub-study of the STEP-wise Survey-Morocco-2017-2018, have complete data on demographic, anthropometric and blood pressure and have provided a valid 24-h urine collection according to the standard protocol of the World Health Organization (WHO). Results: The mean 24-h urinary sodium excretion was 2794 mg (SD, 1394) and the median was 2550 mg (IQR, 1780-3726). The mean 24-h urinary potassium excretion was 1898 mg (SD, 1044) and the median was 1640 mg (IQR, 1170-2410). Sodium excretion was between 3000 and 5000 mg/day in 31% of participants, < 3000 mg/day in 64%, and > 5000 mg/day in only 5%. No significant association of urinary sodium or potassium with blood pressure was found. Conclusion: Sodium intake in the studied population of Moroccan adults was higher than WHO recommendation and was comparable to levels reported in countries from Eastern Mediterranean Region. The vast majority of participants had a sodium intake < 5000 mg/day, with only 5% were above this level. Potassium intake was in the range of 1000 to 3000 mg/day. Within these ranges, there was no association between sodium or potassium intake and blood pressure. This information is crucial to help implement the national strategy to reduce sodium intake as a cost-effective intervention to prevent chronic disease in Morocco.

Diet in the first years of life is an important factor in growth and development. Dietary protein is a critical macronutrient that provides both essential and nonessential amino acids required for sustaining all body functions and procedures, providing the structural basis to maintain life and healthy development and growth in children. In this study, our aim was to describe the total protein intake, type and food sources of protein, the adequacy to the Population Reference Intake (PRI) for protein by the European Food Safety Authority (EFSA), and the Recommended Dietary Allowance (RDA) by the Institute of Medicine (IoM). Furthermore, we analyzed whether the consumption of dairy products (including regular milk, dairy products, or adapted milk formulas) is associated with nutrient adequacy and the contribution of protein to diet and whole dietary profile in the two cohorts of the EsNuPI (in English, Nutritional Study in the Spanish Pediatric Population) study; one cohort was representative of the Spanish population from one to < 10 years old (n = 707) (Spanish reference cohort, SRS) who reported consuming all kinds of milk and one was a cohort of the same age who reported consuming adapted milk over the last year (including follow-on formula, growing up milk, toddler’s milk, and enriched and fortified milks) (n = 741) (adapted milk consumers cohort, AMS). The children of both cohorts had a high contribution from protein to total energy intake (16.79% SRS and 15.63% AMS) and a high total protein intake (60.89 g/day SRS and 53.43 g/day AMS). We observed that protein intake in Spanish children aged one to < 10 years old was above the European and international recommendations, as well as the recommended percentages for energy intakes. The main protein sources were milk and dairy products (28% SRS and 29% AMS) and meat and meat products (27% SRS and 26% AMS), followed by cereals (16% SRS and 15% AMS), fish and shellfish (8% in both cohorts), eggs (5% SRS and 6% AMS), and legumes (4% in both cohorts). In our study population, protein intake was mainly from an animal origin (meat and meat products, milk and dairy products, fish and shellfish, and eggs) rather than from a plant origin (cereals and legumes). Future studies should investigate the long-term effect of dietary protein in early childhood on growth and body composition, and whether high protein intake affects health later in life.

AbstractThe direction and magnitude of the association between sodium and potassium excretion and blood pressure (BP) may differ depending on the characteristics of the study participant or the intake assessment method. Our objective was to assess the relationship between BP, hypertension and 24-h urinary sodium and potassium excretion among Chinese adults. A total of 1424 provincially representative Chinese residents aged 18 to 69 years participated in a cross-sectional survey in 2017 that included demographic data, physical measurements and 24-h urine collection. In this study, the average 24-h urinary sodium and potassium excretion and sodium-to-potassium ratio were 3811.4 mg/day, 1449.3 mg/day, and 4.9, respectively. After multivariable adjustment, each 1000 mg difference in 24-h urinary sodium excretion was significantly associated with systolic BP (0.64 mm Hg; 95% confidence interval [CI] 0.05–1.24) and diastolic BP (0.45 mm Hg; 95% CI 0.08–0.81), and each 1000 mg difference in 24-h urinary potassium excretion was inversely associated with systolic BP (− 3.07 mm Hg; 95% CI − 4.57 to − 1.57) and diastolic BP (− 0.94 mm Hg; 95% CI − 1.87 to − 0.02). The sodium-to-potassium ratio was significantly associated with systolic BP (0.78 mm Hg; 95% CI 0.42–1.13) and diastolic BP (0.31 mm Hg; 95% CI 0.10–0.53) per 1-unit increase. These associations were mainly driven by the hypertensive group. Those with a sodium intake above about 4900 mg/24 h or with a potassium intake below about 1000 mg/24 h had a higher risk of hypertension. At higher but not lower levels of 24-h urinary sodium excretion, potassium can better blunt the sodium-BP relationship. The adjusted odds ratios (ORs) of hypertension in the highest quartile compared with the lowest quartile of excretion were 0.54 (95% CI 0.35–0.84) for potassium and 1.71 (95% CI 1.16–2.51) for the sodium-to-potassium ratio, while the corresponding OR for sodium was not significant (OR, 1.28; 95% CI 0.83–1.98). Our results showed that the sodium intake was significantly associated with BP among hypertensive patients and the inverse association between potassium intake and BP was stronger and involved a larger fraction of the population, especially those with a potassium intake below 1000 mg/24 h should probably increase their potassium intake.

Introduction: We performed a 12-week randomized placebo-controlled crossover study to examine the effects of sodium and potassium supplementation on blood pressure (BP) and arterial stiffness in untreated (pre)hypertensive individuals on a low-sodium, low-potassium diet. Methods: During the study, subjects were on a fully controlled diet that provided on average 2.4 g/d of sodium (equals 6 g/d of salt) and 2.2 g/d of potassium. After a 1-week run-in period, 37 subjects received capsules with supplemental sodium (3 g/d, equals 7.5 g/d of salt), supplemental potassium (3 g/d), or placebo, for four weeks each (not separated by wash-out), in random order. Fasting office BP, 24-h ambulatory BP, and measures of arterial stiffness (SphygmoCor®) were assessed at baseline and after each treatment. Results: Subjects had a mean pre-treatment BP of 145/81 mmHg and 68% (25 of 37) had systolic BP (SBP) ≥140 mmHg. In 36 subjects who completed the study, sodium supplementation increased urinary sodium by 97.6 mmol/24h (2.2 g/d) and potassium supplementation increased urinary potassium by 62.9 mmol/24h (2.5 g/d), compared to placebo (Table). Sodium supplementation significantly increased office BP by 7.5/3.3 mmHg, 24-h BP by 7.0/2.1 mmHg and central BP by 8.5/3.6 mmHg. Potassium supplementation significantly reduced 24-h BP by 4.0/1.7 mmHg. Measures of arterial stiffness did not change. Conclusion: Increasing the intake of sodium has a strong adverse effect on BP in untreated (pre)hypertensive individuals. Increased potassium intake, however, lowers BP even when people are on a reduced sodium diet. Short-term changes in sodium and potassium intake have little effect on arterial stiffness.

Bone problems in the population begin to be establish in childhood. The present study aims to assess the usual calcium, phosphorus, magnesium, and vitamin D intakes, along with the food sources of these nutrients, in Spanish children participating in the EsNuPI (Estudio Nutricional en Población Infantil Española) study. Two 24 h dietary recalls were applied to 1448 children (1 to <10 years) divided into two sub-samples: one reference sample (RS) of the general population [n = 707] and another sample which exclusively included children consuming enriched or fortified milks, here called “adapted milks” (AMS) [n = 741]. Estimation of the usual intake shows that nutrient intake increased with age for all nutrients except vitamin D. Using as reference the Dietary Reference Values from the European Food Safety Authority (EFSA), calcium and magnesium intakes were found to be below the average requirement (AR) and adequate intake (AI), respectively, in a considerable percentage of children. Furthermore, phosphorus exceeded the AI in 100% of individuals and vitamin D was lower than the AI in almost all children studied. The results were very similar when considering only plausible reporters. When analyzing the food sources of the nutrients studied, milk and dairy products contributed the most to calcium, phosphorus, magnesium, and vitamin D. Other sources of calcium were cereals and vegetables; for phosphorus: meat, meat products, and cereals; for magnesium: cereals and fruits; and, for vitamin D: fish and eggs. These results highlight the desirability of improving the intake concerning these nutrients, which are involved in bone and metabolic health in children. The AMS group appeared to contribute better to the adequacy of those nutrients than the RS group, but both still need further improvement. Of special interest are the results of vitamin D intakes, which were significantly higher in the AMS group (although still below the AI), independent of age.

Background: The nutrition societies of Germany, Austria and Switzerland have revised the reference values for potassium intake in January 2017. Methods: For adults, the estimated value was based on the 24-h urinary potassium excretion and on preventive considerations regarding hypertension and stroke. The estimated values for children and adolescents were extrapolated from the adult estimated value considering differences in body mass. For infants aged 0 to under 4 months, the estimated value was set based on the potassium intake via breast milk. From this reference value, the estimated value for infants aged 4 to under 12 months was also derived by extrapolation. The estimated value for lactating women takes into account the potassium loss via breast milk. Results: The estimated values for potassium intake are set at 400 mg/day for breastfed infants aged 0 to under 4 months, 600 mg/day for infants aged 4 to under 12 months, 1,100-4,000 mg/day for children and adolescents, 4,000 mg/day for adults and pregnant women and 4,400 mg/day for lactating women. Conclusions: The consumption of potassium-rich foods should be generally increased. Supplemental intake beyond the estimated values has no health benefit and is therefore not recommended.

Renal Potassium Excretion

The interacting effects of aldosterone and plasma potassium concentration on steady-state renal potassium excretion were studied in two groups of chronically adrenalectomized dogs. In group I (six dogs, 22.9 kg) aldosterone was infused intravenously at 20 micrograms/day while potassium intake was changed in steps of 7-10 days duration from 10 to 30 to 100 meq/day. At the completion of each step, plasma potassium concentration, urinary potassium excretion, and other variables that potentially may affect renal function were measured. In group II (six dogs, 22.2 kg) a similar protocol was followed except that aldosterone was infused at 250 micrograms/day and the potassium intake levels were 30, 100, and 200 meq/day. Plasma potassium concentration and excretion data for the 20 micrograms/day group were: 3.22 +/- 0.26 meq/liter and 5 +/- 1 meq/day, 4.35 +/- 0.08 meq/liter and 21 +/- 2 meq/day, and 5.88 meq/liter and 82 +/- 3 meq/day at the 10, 30, and 100 meq/day intake levels, respectively. For the 250 micrograms/day group the values were: 2.72 +/- 0.18 meq/liter and 28 +/- 7 meq/day, 4.16 +/- 0.14 meq/liter and 71 +/- 8 meq/day, and 4.40 +/- 0.14 meq/liter and 172 +/- 26 meq/day at the 30, 100, and 200 meq/day intake levels. Therefore, the increase in aldosterone infusion rate shifted the relationship between plasma potassium concentration and potassium excretion to the left so that at a given level of plasma potassium a greater amount of potassium was excreted. In the normal range of plasma potassium concentration (4.00-4.40 meq/liter) the increase in aldosterone levels resulted in a four- to eightfold increase in daily potassium excretion.

A hygienic assessment of the eating habits of younger schoolchildren of Smolensk was carried out. A survey of 307 schoolchildren of 3–4 grades with various parameters of physical development in the field of nutrition and lifestyle was carried out. The respondents’ diet showed: insufficient and irregular consumption of food – sources of animal protein (meat, milk and dairy products, fish), lack of vegetables, popularity of fast-food products, sweets and sweet carbonated drinks. The violations in the diet and the level of motor activity are most pronounced in the group of children with overweight and obesity. The results confirm the need to develop preventive measures aimed at developing a healthy eating culture among schoolchildren.
