Sodium Content of Foods Sold in the Spanish Market. Results from the BADALI Project

High sodium/salt intake is a risk factor for Non-Communicable Diseases (NCDs). Excess sodium intake has been associated with high coronary heart disease, stroke and high blood pressure. The sodium daily intake is above the recommendations in the world as well as in Spain. Reducing salt content in processed foods and ready meals is one of the main strategies for reducing sodium intake. The aim of the present work is to characterise the presence of sodium in foods sold in the Spanish market. We also study a possible shift in sodium content in products over the last few years. For this purpose, 3897 products included in the BADALI food database were analysed, classified into 16 groups (G). We found that 93.3% of all foods displayed the sodium/salt content in the nutrition declaration. Meat—processed and derivatives (G8) had the highest mean and median values for sodium content, followed by snacks (G15) and sauces (G14). Only 12.7% of foods were sodium-free (≤ 5 mg/100 g or 100 mL), 32.4% had very low sodium (≤ 40 mg/100 g or 100 mL) and 48.2% were low in sodium (≤ 120 mg/100 g or 100 mL). On the contrary, 47.2% were high in sodium according to the Pan American Health Organisation Nutrient Profile Model (PAHO-NPM), while there were 31.9% according to the Chile-NPM. The agreement between the two NPMs was considered ‘substantial’ (κ = 0.67). When sodium content was compared over the years, no decrease was observed. This analysis was performed in the entire food population, by food group and in matched products. Therefore, more effort should be made by all parties involved in order to decrease the sodium/salt intake in the population.

Introduction. Salt intake above 5 g/person/day is a strong independent risk factor for hypertension, stroke and cardiovascular diseases. Published studies indicate that the main source of salt in human diet is processed ready-to-eat food, contributing with 65-85% to daily salt intake. Objective. The aim of this paper was to present data on salt content of ready-to-eat food retailed in Novi Sad, Serbia, and contribution of the salt contained in 100 g of food to the recommended daily intake of salt for healthy and persons with cardiovascular disease (CVD) risk. Methods. In 1,069 samples of ready-to-eat food, salt (sodium chloride) content was calculated based on chloride ion determined by titrimetric method, while in 54 samples of bottled water sodium content was determined using flame-photometry. Food items in each food group were categorized as low, medium or high salt. Average salt content of each food group was expressed as a percentage of recommended daily intake for healthy and for persons with CVD risk. Results. Average salt content (g/100 g) ranged from 0.36?0.48 (breakfast cereals) to 2.32?1.02 (grilled meat). The vast majority of the samples of sandwiches (91.7%), pizza (80.7%), salami (73.9%), sausages (72.9%), grilled meat (70.0%) and hard cheese (69.6%) had a high salt profile. Average amount of salt contained in 100 g of food participated with levels ranging from 7.2% (breakfast cereals) to 46.4% (grilled meat) and from 9.6% to 61.8% in the recommended daily intake for healthy adult and person with CVD risk, respectively. Average sodium content in 100 ml of bottled spring and mineral water was 0.33?0.30 mg and 33?44 mg, respectively. Conclusion. Ready-to-eat food retailed in Novi Sad has high hidden salt content, which could be considered as an important contributor to relatively high salt consumption of its inhabitants.

Relationship Of

Background: The skeleton is vital to sodium homeostasis, accounting for 40% of the body’s sodium. Research indicates stress and low sodium intake are independently associated with RAAS activation. In certain populations, stress can induce salt sensitivity, increasing the risk of hypertension and target organ damage, but the association of low versus high sodium intake with bone health is controversial. Purpose: This study sought out the relationship of low sodium and stress-induced RAAS activation with bone health. The tested hypothesis was those with lowest sodium intake would have lower total bone mineral density (TBMD) and content (TBMC) associated with stress-induced increases in angiotensin ii (Ang II) and aldosterone (Aldo). Methods: We compared effect of stress on Ang II, Aldo, TBMD and TMBC in healthy Caucasian and African-American adolescents. Subjects were grouped by quartiles based on sodium intake, assessed by urinary sodium excretion. Results: Due to females, overall significant inverse associations are observed between TBMD, TBMC, Ang II and Aldo in the lowest sodium intake quartile. Post-stress, women in the lowest sodium intake quartile showed that increases in both Ang II and Aldo correspond with lower TMBC and TMBD. There was no significance between Ang II, Aldo, TMBC and TMBD in the three highest quartiles of women nor in any male quartile. Conclusion: These data suggest Ang II and Aldo may reduce TMBC and TMBD in women. Stress-induced increases in Ang II and Aldo, with low sodium intake, may further reduce TBMD and TBMC in women. Ang II inhibition and/or moderated salt intake may be an efficacious prevention or treatment against the development of osteoporosis.

AbstractObjectiveTo estimate the impact of choosing food products labelled either as low or high in salt on salt intake in the Finnish adult population.Setting and subjectsThe National FINDIET 2002 survey with 48-hour recalls from 2007 subjects aged 25–64 years. Sodium intake was calculated based on the Fineli® food composition database including the sodium content of natural and processed foods as well as the salt content of recipes. The distribution of salt intake was calculated in different ways: the present situation; assuming that all breads, cheeses, processed meat and fish, breakfast cereals and fat spreads consumed would be either ‘lightly salted’ or ‘heavily salted’ based on the current labelling practice; and, in addition, assuming that all foods would be prepared with 50% less or more salt.ResultsExcluding underreporters, the mean salt intake would be reduced by 1.8 g in men and by 1.0 g in women if the entire population were to choose lightly salted products and further by 2.5 and 1.8 g, respectively, if also salt used in cooking were halved. Choosing heavily salted products would increase salt intake by 2.1 g in men and by 1.4 g in women. In the worst scenarios, salt intake would be further increased by 2.3 g in men and by 1.6 g in women.ConclusionsThese calculations show that the potential impact of labelling and giving consumers the possibility to choose products with less salt is of public health importance. In addition, strategies to reduce the salt content of all food groups are needed.

Sodium Metabolism

SummaryAdult sheep, unweaned and mature weaned calves have been examined by metabolic studies for sodium balance. The ratio of sodium input/output was near unity with only a very small amount of the ingested sodium salt being retained. A positive sodium balance was always present, with excess sodium salt being excreted. The main channel of sodium excretion was the kidney, although when sodium intake was increased the sodium content of the faeces showed a proportional increase. Unweaned calves, a few days old, were quite able to excrete excess sodium salts in concentrated urine.There was a clear difference in preference for sodium salts over water, between weaned calves allowed access to sodium salts while being fed milk, and weaned calves denied sodium salts at the milk feeding stage. Sodium-naive calves showed a marked preference for sodium salt solutions while the sodium-experienced calves showed at best an indifference and sometimes even an aversion. With continued access to sodium salts the volume ingested declined steadily in both groups but food intake remained constant.In both calves and sheep the preference for sodium salts showed considerable variation between animals. The evidence from parallel metabolic studies suggests that this variation indicates that salt intake is controlled by some mechanism, possibly in the central nervous system, which is activated by dynamic sodium metabolism. Our experimental results confirm that ruminants have a well developed salt taste but predilection for sodium salts could be a biochemical manifestation rather than a hedonic propensity.

Lowering and increasing sodium intake in pregnant rats evoke opposite changes in renin–angiotensin–aldosterone system (RAAS) activity and are associated with alterations of blood volume expansion. As augmented uterine blood flow during gestation is linked to increased circulatory volume, we wanted to determine if low- and high-sodium intakes affect the mechanical properties and angiotensin II (AngII) responses of the uterine vasculature. Non-pregnant and pregnant rats received a normal sodium (0.22% Na+) diet. On the 15th day of gestation some animals were moved to a low-sodium (0.03%) diet, whereas others were given NaCl supplementation as beverage (saline, 0.9% or 1.8%) for 7 days. All rats were killed after 7 days of treatment (eve of parturition). Uterine arcuate arteries (>100 μm) were set up in wire myographs under a tension equivalent to 50 mmHg transmural pressure. The pregnancy-associated increase in diameter of the uterine arteries was significantly attenuated on the low-sodium diet and 1.8% NaCl supplementation. The arcuate arteries of non-pregnant rats on the low-sodium diet showed markedly increased responses to AngII and phenylephrine (Phe). Pregnancy also resulted in heightened responses to AngII and Phe that were significantly reduced for the former agent in rats on the low-sodium diet. Sodium supplementation of non-pregnant rats did not affect the reactivity of the uterine arteries to AngII, but significantly reduced the effect of Phe (1 μmol/l). High salt also significantly diminished the elevated responses to AngII in the arteries of pregnant animals. It was observed that altered sodium intake affects the mechanical and reactive properties of the uterine arcuate arteries more importantly in pregnant than in non-pregnant rats. Low-salt intake similarly affected the reactivity of the uterine arcuate arteries to AngII and Phe, whereas high-salt intake more specifically affected AngII responses. These results showed that perturbations of sodium intake have major impacts on the structure and functions of the uterine arterial circulation, indicating RAAS involvement in uterine vascular remodeling and function during gestation.

AbstractThe aim of this study was the detection and quantification of the Na+ depositions in the extracellular matrix of myocardial tissue, which are suggested to be bound by negatively charged glycosaminoglycan (GAG) structures. The presented experimental results are based on high resolution X-ray fluorescence (XRF) spectromicroscopy technique used to perform a comparative analysis of sodium containment in intracellular and interstitial spaces of cardiac tissues taken from animals selected by low and high sodium intake rates. The experimental results obtained show that high sodium daily intake can result in a remarkable increase of sodium content in the myocardial interstitium.

Abstract 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.

1. During 4 weeks 37 normotensive 50-year-old men identified by screening in a random population sample were given 12 g of NaCl daily, in addition to their usual dietary sodium intake. Blood pressure, heart rate, weight, urinary excretion of sodium, potassium and catecholamines, plasma aldosterone and noradrenaline and intra-erythrocyte sodium content were determined on normal and increased salt intake. The subjects were divided into those with a positive family history of hypertension (n = 11) and those without such a history (n = 26). 2. Systolic blood pressure and weight increased significantly irrespective of a positive family history of hypertension. 3. On normal salt intake intra-erythrocyte sodium content was significantly higher in those with a positive family history of hypertension. During high salt intake intra-erythrocyte sodium content decreased significantly in that group and the difference between the hereditary subgroups was no longer significant. 4. In the whole group urinary excretion of noradrenaline, adrenaline and dopamine increased whereas plasma aldosterone decreased during the increased salt intake. 5. Thus, in contrast to some earlier studies performed in young subjects, our results indicate that moderately increased sodium intake acts as a pressor agent in normotensive middle-aged men whether there was a positive family history of hypertension or not. We confirm that men with positive family history of hypertension have an increased intra-erythrocyte sodium content, and that an increase in salt intake seems to increase overall sympathetic activity.

Background— Addition of up to 15.0 g/d salt to the diet of chimpanzees caused large rises in blood pressure, which reversed when the added salt was removed. Effects of more modest alterations to sodium intakes in chimpanzees, akin to current efforts to lower sodium intakes in the human population, are unknown. Methods and Results— Sodium intakes were altered among 17 chimpanzees in Franceville, Gabon, and 110 chimpanzees in Bastrop, Tex. In Gabon, chimpanzees had a biscuit diet of constant nutrient composition except that the sodium content was changed episodically over 3 years from 75 to 35 to 120 mmol/d. In Bastrop, animals were divided into 2 groups; 1 group continued on the standard diet of 250 mmol/d sodium for 2 years, and sodium intake was halved for the other group. Lower sodium intake was associated with lower systolic, diastolic, and mean arterial blood pressures in Gabon (2-tailed P <0.001, unadjusted and adjusted for age, sex, and baseline weight) and Bastrop ( P <0.01, unadjusted; P =0.08 to 0.10, adjusted), with no threshold down to 35 mmol/d sodium. For systolic pressure, estimates were −12.7 mm Hg (95% confidence interval, −16.9 to −8.5, adjusted) per 100 mmol/d lower sodium in Gabon and −10.9 mm Hg (95% confidence interval, −18.9 to −2.9, unadjusted) and −5.7 mm Hg (95% confidence interval, −12.2 to 0.7, adjusted) for sodium intake lower by 122 mmol/d in Bastrop. Baseline systolic pressures higher by 10 mm Hg were associated with larger falls in systolic pressure by 4.3/2.9 mm Hg in Gabon/Bastrop per 100 mmol/d lower sodium. Conclusions— These findings from an essentially single-variable experiment in the species closest to Homo sapiens with high intakes of calcium and potassium support intensified public health efforts to lower sodium intake in the human population.

1. The renal response to aldosterone (urinary sodium and potassium excretion) was determined in adrenalectomized rats previously fed either a high potassium diet or a control diet. High K+ rats showed an enhanced response to aldosterone at all doses tested. 2. This enhanced response to aldosterone required the presence of the adrenal glands during the induction period, could be suppressed by a high sodium intake, but could not be induced by a low sodium diet. 3. No difference between high K+ and control rats could be detected in renal mineralocorticoid receptors, assessed by both in vivo and in vitro binding of tritiated aldosterone. 4. The method of the induction, and the mechanism of the enhanced response, remain to be defined.
