Initiatives to Reduce the Content of Sodium in Food Products and Meals and Improve the Population's Health

Table salt is the main source of sodium (Na) in the human diet. Excessive supply of Na in a diet is strongly linked to many non-communicable human diseases, such as hypertension, obesity and stomach cancer. The World Health Organization recommends that daily intake of salt in adult diets should be kept below 5 g/person/day, which corresponds to 2 g Na/person/day. However, on average, adults consume about 9-10 g/person/day, and children and young people about 7-8 g/person/day. Initiatives to reduce salt intake include modifications of food composition in collaboration with the food industry, education of consumers, salt marking on foodstuff labels and taxation of salt. A need also exists to educate society so that they choose low-sodium products. In view of the food technology and amount of salt intake, the most important and the easiest change to make is to reduce the content of salt in baked goods. This paper analyses the results of surveys regarding strategies to reduce salt content in food products and considers multifaceted initiatives to reduce salt intake as a possible efficient method of improving the population's health status.

Food consumption patterns and nutrient intakes of infants and young children amidst the nutrition transition: the case of Lebanon

BACKGROUND

This is the first study on dietary intakes of infants and young children in the Eastern Mediterranean Region, a region that is currently witnessing the nutrition transition. It aims at characterizing food consumption patterns amongst 0-4 year old children in Lebanon, evaluating their macro- and micronutrient intakes and assessing adherence to dietary recommendations.

METHODS

Based on a national cross-sectional survey in 2012 (n = 866), the study collected data on sociodemographic and anthropometric characteristics, and one 24-hour dietary recall was administered. Nutrient intakes were compared with reference values: Estimated Average Requirement (EAR), Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR).

RESULTS

Milk was the highest contributor to energy intake (EI) in infants (95.8 and 56.5% in 0-5.9 months and 6-11.9 months old infants, respectively), while its intake was lower among toddlers and preschoolers (35.4 and 15.1%, respectively). In contrast, intakes of sweets and sweetened beverages were the highest in preschoolers compared to younger children, contributing 18.5% EI in preschoolers. Compared to dietary guidelines, the lowest dietary adherence was found for vegetables (17.8-20.7%) and fruits (14.4-34.3%). Protein intake was within the recommendations for the vast majority of children. Although total fat intake was lower in toddlers and preschoolers compared to infants, more than 40% of toddlers and preschoolers exceeded the AMDR for fat and 87.3% of preschoolers exceeded the upper limit for saturated fat. Only 3.6% of toddlers and 11.5% of preschoolers exceeded the AI level for dietary fiber. Micronutrient intake assessment showed that mean intakes in infants exceeded the AI for all micronutrients, except for vitamin D and magnesium. In toddlers, vitamin D and calcium were below the EAR among 84.7, and 44.6%, respectively. In preschoolers, most of the children (91.9%) had inadequate intakes of vitamin D, and a third had inadequate intakes of folate, calcium and vitamin A.

CONCLUSIONS

This study identified priority issues for nutrition intervention in infants and young children in Lebanon. Concerted multi-stakeholder efforts are needed to instill heathier food consumption and nutrient intake patterns early in life.

Religious dietary rules and their potential nutritional and health consequences

BACKGROUND

The vast majority of the world population declares affiliation to a religion, predominantly Christianity and Islam. Many religions have special dietary rules, which may be more or less strictly adhered to.

METHODS

Religious food rules were collected from holy books and religious websites as well as their translation into dietary practices. The literature was searched for potential associations between these rules and potential nutritional consequences.

RESULTS

Jewish, Islamic and Indian religions support prolonged breastfeeding. Religious avoidance of alcohol is probably beneficial to health. When strictly applied, a few rules may lead to nutritional inadequacies, mainly in populations living in unfavourable socio-economic or environmental conditions. In Jewish and Muslim observants, animal slaughtering procedures may increase the risk of iron deficiency. Jews may be at risk of excess sodium intake related to home-prepared foods. A vegan diet, as observed by some believers, often by drifting from original precepts, or by some Hindus or Buddhists, may result in vitamin B12, calcium, iron, zinc, selenium and n-3 fatty acids deficiencies.

CONCLUSION

When implemented in accordance with the rules, most religious food precepts are not detrimental to health, as suggested by the fact that they have more or less been followed for millennia. Nevertheless, some practices may lead to nutritional inadequacies, such as iron, calcium, vitamin D and vitamin B12 deficiencies. Patients with low socio-economic status, children and women of childbearing age are of particular risk of such deficiencies. Being aware of them should help health professionals to take an individualized approach to decide whether to supplement or not.

Mineral and vitamin intake of infants and young children: the Nutri-Bébé 2013 survey

PURPOSE

Minerals and vitamins are essential for optimal growth and development, particularly during the first years of life. Therefore, regularly evaluating their intake makes sense. For this purpose, we report the data from the Nutri-Bébé 2013 survey in comparison with the European Food Safety Authority Adequate Intake (AI), or Average Requirement, (AR) according to age.

METHODS

This observational, nationally representative, cross-sectional survey was conducted in 1035 non-breastfed French children aged 0.5-35 months. Dietary intake was recorded using a food diary on three non-consecutive days, framed by two face-to-face interviews.

RESULTS

The intake of zinc, magnesium and water-soluble vitamins most of the time met the recommendations. From the first weeks of life, sodium intake exceeded the AI, with a maximum median intake of 1137 mg/day after the age of 30 months. However, it has decreased since 2005. Calcium median intake often exceeded the AI or AR, reaching a maximum of 780 mg/day between 18 and 23 months. Median vitamin A intake always exceeded the AI or AR but exceeded the recommended upper limit in only a few cases. After 2 years, median iron intake was clearly below the AR, i.e. lower than 6.0 mg/day. Dietary vitamin D intake was below the AI, thereby justifying adequate supplementation. Vitamin E intake was below the AI in 50-75% of toddlers.

CONCLUSION

This survey highlights excessive sodium intake as well as a shortfall of iron, vitamin D, and vitamin E intakes. The potential consequences of these discrepancies with respect to health outcomes remain to be assessed.

Frequency of Use of Added Sugar, Salt, and Fat in Infant Foods up to 10 Months in the Nationwide ELFE Cohort Study: Associated Infant Feeding and Caregiving Practices

The consumption of sugar, salt, and fat in infancy may influence later health. The objective of this study was to describe the frequency of use of added sugar, salt, and fat during the complementary feeding period and the associated infant caregiving practices. Data were obtained from a monthly questionnaire filled by parents for 10,907 infants from the French Etude Longitudinale Française depuis l'Enfance (ELFE) cohort. A score of frequency of use (SU) for added sugar, salt, and fat (oil, margarine, butter, and/or cream) was calculated from the age at complementary feeding introduction (CFI) to the 10th month. Associations between the SU of each added ingredient with infant feeding and caregiving practices were studied with multivariable linear regressions adjusted for familial characteristics. Only 28% of the parents followed the recommendation of adding fat and simultaneously not adding sugar or salt. Breastfeeding mothers were more prone to add sugar, salt, and fat than non-breastfeeding mothers. CFI before four months was positively associated with the SU of added sugar and salt and negatively associated with the SU of added fat. The use of commercial baby food was negatively related to the SU of added salt and fat. The use of these added ingredients was mainly related to breastfeeding, age at CFI, and use of commercial food, and it was independent of the household socioeconomic characteristics.

[Measurement of dietary sodium intake in a group of children from one to 18 months of age in a pediatric service in Cali, Colombia]

INTRODUCTION

The fatty streaks in an arterial wall can appear from the third year of age, and they show an association with atherogenic risk factors such as hypertension and sodium in the diet. Given the difficulty of data gathering, few studies report the intake of sodium in the diet.

OBJECTIVE

To determine average sodium intake in the diet of children between one and 18 months of age through a three-day dietary survey.

MATERIALS AND METHODS

This was a cross-sectional study with 48 children without renal disease or diet restrictions seen in pediatric practice between January and June, 2011. It included a dietary survey for the parents, nutritional status classification by anthropometry, and blood pressure measurements. Sodium content and other nutrients in the diet program were analyzed with the International Food Consumption Program (CERES), anthropometry with the World Health Organization Anthro program, and Epi-info for socio-demographic characteristics.

RESULTS

In total, 69% of children had high sodium consumption, 6.2% had high blood pressure, and 20.7% were overweight and obese.

CONCLUSIONS

The prevalence of hypertension exceeds that reported for Colombia (1-3%). Two of the three children with high blood pressure had high sodium intake and they were overweight and obese, with values above those reported for Colombian children (16%). We suggest to measure blood pressure early, and to restrict salt and sugar in food for infants and children under two years of age. Also, larger studies should be conducted to collect population data on sodium intake and develop appropriate and timely intervention strategies to reduce risks in adulthood.

Role of Young Child Formulae and Supplements to Ensure Nutritional Adequacy in U.K. Young Children

The European Food Safety Authority (EFSA) states that young child formulae (YCFs) "cannot be considered as a necessity to satisfy the nutritional requirements" of children aged 12-36 months. This study quantifies the dietary changes needed to ensure nutritional adequacy in U.K. young children who consume YCFs and/or supplements and in those who do not. Dietary data from 1147 young children (aged 12-18 months) were used to identify, using linear programming models, the minimum changes needed to ensure nutritional adequacy: (i) by changing the quantities of foods initially consumed by each child (repertoire-foods); and (ii) by introducing new foods (non-repertoire-foods). Most of the children consumed neither YCFs, nor supplements (61.6%). Nutritional adequacy with repertoire-foods alone was ensured for only one child in this group, against 74.4% of the children consuming YCFs and supplement. When access to all foods was allowed, smaller food changes were required when YCFs and supplements were initially consumed than when they were not. In the total sample, the main dietary shifts needed to ensure nutritional adequacy were an increase in YCF and a decrease in cow's milk (+226 g/day and -181 g/day, respectively). Increasing YCF and supplement consumption was the shortest way to cover the EFSA nutrient requirements of U.K. children.
