BACKGROUND: Although low sodium intake (<2 g/day) and high potassium intake (>3.5 g/day) are proposed as public health interventions to reduce stroke risk, there is uncertainty about the benefit and feasibility of this combined recommendation on prevention of stroke.
METHODS: We obtained random urine samples from 9,275 cases of acute first stroke and 9,726 matched controls from 27 countries and estimated the 24-hour sodium and potassium excretion, a surrogate for intake, using the Tanaka formula. Using multivariable conditional logistic regression, we determined the associations of estimated 24-hour urinary sodium and potassium excretion with stroke and its subtypes.
RESULTS: Compared with an estimated urinary sodium excretion of 2.8-3.5 g/day (reference), higher (>4.26 g/day) (odds ratio [OR] 1.81; 95% confidence interval [CI], 1.65-2.00) and lower (<2.8 g/day) sodium excretion (OR 1.39; 95% CI, 1.26-1.53) were significantly associated with increased risk of stroke. The stroke risk associated with the highest quartile of sodium intake (sodium excretion >4.26 g/day) was significantly greater (P < 0.001) for intracerebral hemorrhage (ICH) (OR 2.38; 95% CI, 1.93-2.92) than for ischemic stroke (OR 1.67; 95% CI, 1.50-1.87). Urinary potassium was inversely and linearly associated with risk of stroke, and stronger for ischemic stroke than ICH (P = 0.026). In an analysis of combined sodium and potassium excretion, the combination of high potassium intake (>1.58 g/day) and moderate sodium intake (2.8-3.5 g/day) was associated with the lowest risk of stroke.
CONCLUSIONS: The association of sodium intake and stroke is J-shaped, with high sodium intake a stronger risk factor for ICH than ischemic stroke. Our data suggest that moderate sodium intake-rather than low sodium intake-combined with high potassium intake may be associated with the lowest risk of stroke and expected to be a more feasible combined dietary target.

Increased dietary sodium intake is a modifiable risk factor for cardiovascular disease. The monitoring of population sodium intake is a key part of any salt reduction intervention. However, the extent and methods used for as-sessment of sodium intake in Southeast Asia is currently unclear. This paper provides a narrative synthesis of the best available evidence regarding levels of sodium intake in six Southeast Asian countries: Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam, and describes salt reduction measures being undertaken in these countries. Electronic databases were screened to identify relevant articles for inclusion up to 29 February 2012. Reference lists of included studies and conference proceedings were also examined. Local experts and researchers in nutrition and public health were consulted. Quality of studies was assessed using a modified version of the Downs and Black Checklist. Twenty-five studies fulfilled the inclusion criteria and were included in this review. Full texts of 19 studies including government reports were retrieved, with most studies being of good quality. In-sufficient evidence exists regarding salt intakes in Southeast Asia. Dietary data suggest that sodium intake in most SEA countries exceeded the WHO recommendation of 2 g/day. Studies are needed that estimate sodium intake using the gold standard 24-hour urinary sodium excretion. The greatest proportion of dietary sodium came from added salt and sauces. Data on children were limited. The six countries had salt reduction initiatives that differed in specificity and extent, with greater emphasis on consumer education.

1 Increased renal vascular resistance is one renal functional abnormality that contributes to hypertension, and alpha(1)-adrenoceptors play a pivotal role in modulating this renal vascular resistance. This study investigates the functional contribution of alpha(1)-adrenoceptor subtypes in the renal cortical vasculature of Wistar-Kyoto rats on a normal sodium diet (WKYNNa) compared with those given saline to drink for 6 weeks (WKYHNa). 2 The renal cortical vascular responses to the adrenergic agonists noradrenaline (NA), methoxamine (ME) and phenylephrine (PE) were measured in WKYHNa and WKYNNa rats either in the absence (the control phase) or presence of chloroethylclonidine (CEC), an alpha(1B)-adrenoceptor antagonist, 5-methylurapidil (5-MeU), an alpha(1A) antagonist, or BMY7378, an alpha(1D) antagonist. 3 Results showed a greater renal cortical vascular sensitivity to NA, PE and ME in the WKYHNa compared with WKYNNa rats (P < 0.05). Moreover, 5-MeU and BMY7378 attenuated adrenergically induced renal cortical vasoconstriction in WKYHNa and WKYNNa rats; this response was largely blunted in CEC-treated WKYHNa rats (all P < 0.05) but not in CEC-treated WKYNNa rats. 4 The data suggest that irrespective of dietary sodium content, in Wistar-Kyoto rats alpha(1A)- and alpha(1D)-subtypes are the major alpha(1)-adrenoceptors in renal cortical vasculature; however, there appears to be a functional involvement of alpha(1B)-adrenoceptors in the WKYHNa rats.

PMID: 30254242 DOI: 10.1038/s41430-018-0300-1

BACKGROUND/OBJECTIVE: Taste is of key importance in food choice and dietary patterns, but studies on taste profiles are limited. We previously assessed dietary taste patterns by 24 h recalls (24hR), but for epidemiological studies food frequency questionnaires (FFQ) may also be suitable. This study compared dietary taste patterns based on FFQ against 24hR and biomarkers of exposure.
SUBJECTS/METHODS: A taste database including 467 foods' sweet, sour, bitter, salt, umami and fat sensation values was combined with food intake data to assess dietary taste patterns: the contribution to energy intake of 6 taste clusters. The FFQ's reliability was assessed against 3-d 24hR and urinary biomarkers for sodium (Na) and protein intake (N) in Dutch men (n = 449) and women (n = 397) from the NQplus validation study (mean age 53 ± 11 y, BMI 26 ± 4 kg/m2).
RESULTS: Correlations of dietary taste patterns ranged from 0.39-0.68 between FFQ and 24hR (p

The CORFIS (Community-Based Cardiovascular Risk Factors Intervention Strategies) program was piloted in community clinics in Malaysia to address the lack of health education in chronic disease management. The stages of change model was applied in a multicenter quasi-experimental design to evaluate adherence to advocated behaviors in CORFIS patients with hypertension. Based on submitted diet and exercise records (n = 209), adherence to sodium reduction, regular exercise, and increasing fruit and vegetable intake behaviors were quantified against weight, waist circumference (WC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) changes. Patients were categorized at 6 months into nonadherent/N-A (Precontemplation, Contemplation, and Preparation), newly adherent/NA (Action) and totally adherent/TA (Maintenance) groups. Self-reported adherence records did not meet recommended targets for healthful behaviors, but clinical benefits were achieved by adherent groups as indicated by effect size (Cohen's d) comparisons. SBP reduction was associated with adherence to sodium reduction in NA (d = 0.60, p < .001) and TA (d = 0.45, p < .001) compared to N-A (d = 0.13, p > .05). Marginally increasing fruit and vegetable consumption (Δ = 0.41 servings) resulted in sizeable reductions in weight for NA (d = 0.81, p < .001) > TA (d = 0.54, p < .001) > N-A (d = 0.21, p > .05) and in WC for NA (d = 0.68, p < .00) > TA (d = 0.53, p < .001) > N-A (d = 0.52, p > .05). Exercise behavior was least successful as pedometer counting was below 10,000 steps but sizeable weight and WC reductions were largest for NA (d = 0.71 and 0.79, respectively) > TA (d = 0.60 and 0.53, respectively) > N-A (d = 0.33 and 0.35, respectively). Patients reporting a shift to positive stages of change behaviors enjoyed clinically beneficial reductions in SBP, DBP, weight, and WC.

Impact of different dietary sodium reduction strategies on blood pressure: a systematic review

Lai JS, Aung YN, Khalid Y, Cheah SC

Hypertens Res, 2022 Nov;45(11):1701-1712.
PMID: 35986189 DOI: 10.1038/s41440-022-00990-5

High sodium intake was found to be associated with increased blood pressure. Decreasing dietary sodium intake can effectively reduce blood pressure, especially among hypertensive individuals, but the extent of reduction remains debatable. The effectiveness of different sodium reduction strategies on blood pressure reduction was identified in the current review. Randomized controlled trials and clinical trials on dietary sodium intake and blood pressure published from 23 March 2008 to 23 March 2021 were collected from the PubMed database. Twenty-six studies were included and divided into four subgroups based on the types of interventions identified. Subgroups included a low-sodium diet (1) in a group with or without added sodium, (2) through food substitutes, (3) through health education and behavior change, and (4) through salt substitutes. Reduction of dietary sodium intake resulted in a mean difference of 4.51 mmHg (95% CI: 3.35-5.67) in systolic blood pressure and 2.42 mmHg (95% CI: 1.61-3.23) in diastolic blood pressure. The effectiveness of these strategies was approximated from the difference in 24-h urinary sodium excretion between the intervention and control groups, which was 53.74 mmol/day (95% CI: 31.95-75.53). When analyzed, the low-sodium diet without added sodium showed the greatest significant differences in blood pressure (7.58/4.01 mmHg) and 24-h urinary sodium excretion (101.49 mmol/day), whereas the low-sodium diet through food substitutes yielded the lowest significant differences in blood pressure (2.26/0.81 mmHg) and 24-h urinary sodium excretion (25.78 mmol/day). Thus, reducing sodium intake can be an effective strategy for the prevention and treatment of hypertension.

The banana pseudo-stem is not currently utilised in the food industry. The aim of this research was to investigate the chemical and pasting profile of banana pseudo-stem flour (BPF). Wheat flour were substituted with BPF (0, 5, 15 and 30%) and the pasting profile were determined. Results from mineral analysis showed that the levels of sodium (Na), potassium (K), calcium (Ca), magnesium (Mg) and phosphorus (P) were higher than those of iron (Fe), zinc (Zn) and manganese (Mn). The BPF had a 0.04% total titratable acidity (TTA) and a total soluble solid (TSS) of 1.30⁰ Brix with pH 5.41. BPF contained 28.26% total starch, 12.81% resistant starch and a total digestible starch value of 15.45%. An increased substitution level of BPF into wheat flour significantly (p

Cavendish (Musa paradisiaca L, cv cavendshii) and Dream (Musa acuminata colla. AAA, cv ‘Berangan’) banana flours were prepared from ripe fruits collected from eleven markets located in Penang, Malaysia. The mineral composition (Na, K, Ca, Mg, Cu, Fe, Mn, Zn) of the flour were analyzed by atomic absorption spectrophotometer and the data obtained were analyzed using logistic regression model. Ripe banana flours were rich source of K and a fair source of other minerals, however logistic regression model identified Mg as an indicator to discriminate between the two types of banana flour affording 100 % correct assignation. Based on this result, mineral analysis may be suggested as a method to authenticate ripe banana flour. This study also presents the usefulness of logistic regression technique for analysis and interpretation of complex data.

There are several methods available for assessment of sodium intake, including dietary and urinary excretion, which are fraught with methodological difficulties. Therefore, the aim of this study was to validate dietary and urinary excretion methods against 24-hour urinary excretion method in estimating sodium intake in Malaysian adults. A cross-sectional study has been carried out between November to December 2015. About 1568 adults aged 18 to 59 years old have participated from 16 study sites located in the 13 states and two federal territories of Malaysia. The study collected basic socio-demographic data and habitual dietary intake by Food Frequency Questionnaire (FFQ). Respondents were also asked to complete a two-day food intake diary (2FD) and collect their 24-hours urine and spot urine using standard protocols. A total of 1116 adults successfully completed the survey, yielding a response rate of 71%. Sodium intake from 24-hour urine excretion was estimated at 2585.9mg/day which is above the recommendation by World Health Organization (WHO). The 2FD showed the nearest mean estimate to the reference method but the spot urine with Tanaka’s predictive equation showed the least bias. The estimation of sodium from spot urine alone or with Kawasaki’s predictive equation and FFQ method showed poor mean estimates and a large bias compared to the reference method. The 2FD and spot urine with Tanaka’s prediction equation can be good alternatives for estimating daily sodium intake at the population level but not at the individual level.

PMID: 32260382 DOI: 10.3390/ijerph17072469

Salt content in processed foods is high, and it is usually used as preservatives, stabilizers, and color enhancers in the products. Increased consumption of processed foods in the modern world has contributed to a high salt intake and thus increased the prevalence of hypertension among Malaysian populations. Therefore, this study aimed to identify and compare salt content in processed food products available in supermarkets and determine the percentage of processed food products exceeding the reference value stated in International Product Criteria (2016). The percentage of processed food products without salt and sodium labeling was determined in this study, in which 76.5% of unlabeled processed food products were made in Malaysia, while 23.5% were imported products. The food group with the highest average salt content was gravy and sauce (3.97 g/100 g), followed by soup (2.95 g/100 g), cheese (2.14 g/100 g), meat (1.37 g/100 g), fish (1.25 g/100 g), chicken (1.20 g/100 g), vegetables (1.18 g/100 g), butter and margarine (1.13 g/100 g), breakfast cereal (0.94 g/100 g), savory snacks (0.90 g/100 g), flatbread (0.86 g/100 g), sweet snacks (0.30 g/100 g), and potato (0.29 g/100 g). In addition, 79.5% of butter and margarine products had an average salt content above the reference value stated in the International Product Criteria, followed by gravy and sauce (79.3%), vegetables (72%), soup (50%), fish (49.2%), breakfast cereal (41%), cheese (36.6%), potato (36%), savory and sweet snacks (29.1), meat (12.5%) and chicken products (2.3%). Most processed food products available in local supermarkets were high in salt content.

Alkarkhi AF, Ramli SB, Easa AM

Int J Food Sci Nutr, 2009;60 Suppl 4:116-25.
PMID: 19115121 DOI: 10.1080/09637480802609368

Major (sodium, potassium, calcium, magnesium) and minor elements (iron, copper, zinc, manganese) and one heavy metal (lead) of Cavendish banana flour and Dream banana flour were determined, and data were analyzed using multivariate statistical techniques of factor analysis and discriminant analysis. Factor analysis yielded four factors explaining more than 81% of the total variance: the first factor explained 28.73%, comprising magnesium, sodium, and iron; the second factor explained 21.47%, comprising only manganese and copper; the third factor explained 15.66%, comprising zinc and lead; while the fourth factor explained 15.50%, comprising potassium. Discriminant analysis showed that magnesium and sodium exhibited a strong contribution in discriminating the two types of banana flour, affording 100% correct assignation. This study presents the usefulness of multivariate statistical techniques for analysis and interpretation of complex mineral content data from banana flour of different varieties.

In vitro calcium availability in bakery products fortified with tuna bone powder as a natural calcium source

Nemati M, Kamilah H, Huda N, Ariffin F

Int J Food Sci Nutr, 2015 Aug;67(5):535-40.
PMID: 27144766 DOI: 10.1080/09637486.2016.1179269

Avoidance of dairy products due to lactose intolerance can lead to insufficiency of calcium (Ca) in the body. In an approach to address this problem, tuna bone powder (TBP) was formulated as a calcium supplement to fortify bakery products. In a study, TBP recovered by alkaline treatment contained 38.16 g/100 g of calcium and 23.31 g/100 g of phosphorus. The ratio of Ca:P that was close to 2:1 was hence comparable to that in human bones. The availability of calcium in TBP was 53.93%, which was significantly higher than most calcium salts, tricalcium phosphate (TCP) being the exception. In vitro availability of calcium in TBP-fortified cookies or TCP-fortified cookies were comparable at 38.9% and 39.5%, respectively. These values were higher than the readings from TBP-fortified bread (36.7%) or TCP-fortified bread (37.4%). Sensory evaluation of bakery products containing TBP or TCP elicited comparable scores for the two additives from test panels. Hence, TBP could be used in the production of high calcium bakery products that would enjoy consumer acceptance.

J Pak Med Assoc, 2021 Feb;71(Suppl 2)(2):S68-S73.
PMID: 33785945

OBJECTIVE: To identify the prevalence of hypertension and its relationship with dietary sodium intake among the Malay population in Selangor, Malaysia.
Methods: Respondents were recruited from the year 2013 to 2015 from households in Klang Valley (urban area) and several settlements of the Federal Land Development Authority (FELDA) in Selangor (rural area). Data were collected using two questionnaires, a sociodemographic questionnaire and a food frequency questionnaire.
RESULTS: A total of 3,453 adults participated in this study. The mean age of the respondents was 50.9 (±10.23) years. The prevalence of hypertension was 23.3%. Mean dietary sodium consumption was 3.6 (±6.63) grams/day, 1.6 grams higher than the current WHO recommendation. The prevalence of hypertension was higher among males aged 60 years and older; among rural population with low education level; among housewives and those with high dietary sodium intake. After adjusting for age, gender and marital status in a multiple logistic regression analysis, rural location (OR = 5.81) and high sodium intake (OR = 2.33) have been shown to affect the incidence of hypertension.
CONCLUSIONS: A substantial proportion of Malay population in Selangor was hypertensive with a higher sodium intake than the WHO recommendation. Hypertension was associated with rural location and high sodium intake. Sustainable and cost-effective population-based health promotion and prevention interventions using a multi-sectoral approach are needed to ensure sufficient community sodium intake.

Meat tenderness is an important quality attribute that influences consumer acceptance. The application of mechanical treatment by mean to reduce toughness of meat cuts has gained much interest recently, with an intention to make use the lower grade meat cuts. This review deliberates the function, mechanism and numerous types of mechanical work in meat tenderization. The mechanical work employs to make meat softer by loosening the muscle structure and disrupting muscle cell. Previous studies have thoroughly examined the use of mechanical treatment (such as massaging, tumbling, and grinding) as an effective meat tenderization technique. Besides that, current research on newly emerging processing technology such as highpressure process (HPP) also shows potential to be explored. The application of mechanical work has shown impressive outcomes by reducing the shear force value that represents hardness of meat. The present paper also described the physical, biochemical and the structural changes of the meat. Finally, the improvements in the meat tenderness by using various type of mechanical work are presented in this paper.

Abnormal intraocular pressure (IOP) if left untreated it can lead to glaucoma and permanent vision loss. However, the correlation between IOP and body weight status, sodium intake, and blood pressure (BP) are unclear among adolescents. This cross-sectional study aimed to determine the relationship between body weight status, sodium intake, and BP with IOP among orang Asli adolescents. A total sample of 50 adolescents of Orang Asli aged 13 to 17 participated in this study. Three days' dietary intake was recorded through 24-hour diet recall to determine the sodium intake. The questionnaire was administered to acquire socio-demographic information, and measurements Body Mass Index (BMI) and BP were done according to standard protocols, and IOP was measured using Tonopen. Data obtained involving 40% boys and 60% girls. Two boys (4%) were underweight, 13 boys (26%) and 17 (34%) girls were normal weight, 4 (8%) boys and 11 (22%) girls were overweight, 1 (2%) boy and 2 (4%) girls were obese. Sixty percent of subjects have exceeded the Lowest-Observed-Adverse-Effect-Level (LOAEL) of 2300 mg of sodium intake. Hypertension stage 1 was found higher than hypertension stage 2 in male and female subjects, with 38% of the female have stage 1 hypertension compared to only 14% in male subjects. 98% of subjects have normal IOP and only 2% of subjects have high IOP.

Computed tomography (CT) is a widely used imaging modality. Although hyponatremia after CT imaging is rare, its effects can be devastating. Hyperosmolar radiocontrast acts as effective osmoles and causes fluid migration from intracellular into extracellular compartment. Dilutional hyponatremia will ensue if translocation of fluid is in excess of diuresis. This case report detailed an unusual case of acute symptomatic hyponatremia after CT renal protocol and the treatments given after its recognition.

Fulltext Is socio-demographic status, body mass index, and consumption of food away from home associated with high sodium intake among adults in Malaysia?: findings from the Malaysian Community Salt Survey (MyCoSS)

Salleh R, Ganapathy SS, Ibrahim Wong N, Cheong SM, Ahmad MH, Palaniveloo L, et al.

J Health Popul Nutr, 2021 05 31;40(Suppl 1):12.
PMID: 34059166 DOI: 10.1186/s41043-021-00236-z

BACKGROUND: Studies have shown that having away from home meals contributes to high sodium intake among young people and those who lived in urban areas. This study aimed to determine the association between dietary sodium intake, body mass index, and away from home meal consumption behaviour among Malaysian adults.
METHODS: MyCoSS was a cross-sectional household survey involving 1440 adults age 18 years and above. This study utilized stratified cluster sampling to obtain a nationally representative sample. Data was collected between October 2017 and March 2018. Socio-demographic information, dietary assessment using food frequency questionnaire (FFQ), and away from home meal consumption were assessed through a face-to-face interview by trained health personnel. Descriptive analysis and logistic regression were applied to identify the association of socioeconomic status and away from home meal consumption with dietary sodium intake.
RESULTS: A total of 1032 participants completed the FFQ, with a mean age of 48.8 + 15.6 years. Based on the FFQ, slightly over half of the participants (52.1%) had high sodium intake. Results showed that 43.6% of participants consumed at least one to two away from home meals per day, while 20.8% of them had their three main meals away from home. Participants aged less than 30 years old were the strongest predictor to consume more sodium (adjusted OR: 3.83; 95%CI: 2.23, 6.58) while those of Indian ethnicity had significantly lower sodium intake. Surprisingly, having three away from home meals per day was not associated with high dietary sodium intake, although a significant association (crude OR; 1.67, 95% CI: 1.19, 2.35) was found in the simple logistic regression. Obese participants were less likely to have high dietary sodium intake compared with the normal BMI participants in the final model.
CONCLUSION: Over half of the participants consumed sodium more than the recommended daily intake, especially those who consumed three away from home meals. However, there was no significant association between high sodium intake and having three away from home meals per day. The promotion of healthy cooking methods among the public must continue to be emphasized to reduce the dietary sodium intake among Malaysian adults.

BACKGROUND: Excessive intake of sodium is a major public health concern. Information on knowledge, perception, and practice (KPP) related to sodium intake in Malaysia is important for the development of an effective salt reduction strategy. This study aimed to investigate the KPP related to sodium intake among Malaysian adults and to determine associations between KPP and dietary sodium intake.
METHODS: Data were obtained from Malaysian Community Salt Survey (MyCoSS) which is a nationally representative survey with proportionate stratified cluster sampling design. A pre-tested face-to-face questionnaire was used to collect information on socio-demographic background, and questions from the World Health Organization/Pan American Health Organization were adapted to assess the KPP related to sodium intake. Dietary sodium intake was determined using single 24-h urinary sodium excretion. Respondents were categorized into two categories: normal dietary sodium intake (< 2000 mg) and excessive dietary sodium intake (≥ 2000 mg). Out of 1440 respondents that were selected to participate, 1047 respondents completed the questionnaire and 798 of them provided valid urine samples. Factors associated with excessive dietary sodium intake were analyzed using complex sample logistic regression analysis.
RESULTS: Majority of the respondents knew that excessive sodium intake could cause health problems (86.2%) and more than half of them (61.8%) perceived that they consume just the right amount of sodium. Overall, complex sample logistic regression analysis revealed that excessive dietary sodium intake was not significantly associated with KPP related to sodium intake among respondents (P > 0.05).
CONCLUSION: The absence of significant associations between KPP and excessive dietary sodium intake suggests that salt reduction strategies should focus on sodium reduction education includes measuring actual dietary sodium intake and educating the public about the source of sodium. In addition, the relationship between the authority and food industry in food reformulation needs to be strengthened for effective dietary sodium reduction in Malaysia.
