RESUMO
The availability, purchase and consumption of foods high in fat, sugars and salt and low in fibre are linked to the high health and economic burden of noncommunicable diseases, including cancer, in Europe. Therefore, assessing the quality of the food offer is key as feedback to decision makers, as well as to identify good practices and areas of the food supply still requiring urgent action. We combined detailed market share and sales data with nutrition composition data to evaluate the nutritional quality of 14 packaged food and soft drinks categories sold across 22 European countries over the 2015-2018 period. Our analysis shows great variability of the nutritional composition within and among packaged food and soft drinks categories across European countries. Our estimates of the market-share weighted mean, a measure that integrates possible changes in nutrient content with the amount of a product sold to consumers, as well as daily per capita nutrient sale estimates, suggest a small but statistically significant progress in certain food categories only. Overall, the amounts of sugars, saturated fat, salt and fibre being sold to European citizens through these products is not improving to an extent to meet public health objectives.

INTRODUCTION: Modulation of the human gut microbiota is emerging as a plausible approach to promoting health and preventing and treating disease. Changes in dietary macronutrients, mainly in carbohydrates, exert specific effects on the human gut microbiota. Specifically, there is evidence that supports that dietary fiber may influence the abundance, diversity, and metabolism of the human gut microbiota. This work contributes to the understanding of the impact of intact cereal fiber consumption on the gut microbiota of healthy adults. The strongest evidence points to the role of wheat bran and wholegrain wheat fiber promoting gut microbiota diversity, since wheat fiber demonstrated the most consistent prebiotic effects, with demonstrable effects, with an increase in wheat fiber as low as 6 g/day.
INTRODUCCIÓN: La modulación de la microbiota intestinal está emergiendo como un enfoque plausible para promover la salud así como la prevención y el tratamiento de las enfermedades. Los cambios en los macronutrientes de la dieta tienen efectos específicos sobre la microbiota intestinal de los individuos. Específicamente, existe evidencia que sugiere que la fibra dietética puede modificar la abundancia, la diversidad y el metabolismo de la microbiota intestinal. Este trabajo contribuye a la comprensión del impacto del consumo de las fibras intactas de los cereales sobre la microbiota intestinal. La evidencia más sólida apunta al papel del salvado de trigo y la fibra de trigo integral como promotores de la diversidad de la microbiota intestinal, ya que la fibra de trigo demostró los efectos prebióticos más consistentes, con un aumento de tan solo 6 g al día.

Confusion has persisted for decades in the United States (U.S.) over how much plain water to drink, despite national water intake recommendations which are based on high quality scientific evidence. This editorial summarizes the definition, alignment and coordination of evidence that informs the current U.S. adequate intake (AI) recommendations for water. It highlights gaps in the evidence that perpetuate confusion and opportunity to address the gaps through strategic planning.

The recommendation to limit dietary saturated fatty acid (SFA) intake has persisted despite mounting evidence to the contrary. Most recent meta-analyses of randomized trials and observational studies found no beneficial effects of reducing SFA intake on cardiovascular disease (CVD) and total mortality, and instead found protective effects against stroke. Although SFAs increase low-density lipoprotein (LDL) cholesterol, in most individuals, this is not due to increasing levels of small, dense LDL particles, but rather larger LDL particles, which are much less strongly related to CVD risk. It is also apparent that the health effects of foods cannot be predicted by their content in any nutrient group without considering the overall macronutrient distribution. Whole-fat dairy, unprocessed meat, and dark chocolate are SFA-rich foods with a complex matrix that are not associated with increased risk of CVD. The totality of available evidence does not support further limiting the intake of such foods.

OBJECTIVE: To synthesise evidence of urban dietary behaviours (macronutrients, types of foods, dietary diversity and dietary practices) in two African countries in relation to postulated changes in the context of nutrition transition. DESIGN: Systematic review and meta-analyses, including six online databases and grey literature, 1971-2018 (Protocol CRD42017067718). SETTING: Urban Ghana and Kenya. PARTICIPANTS: Population-based studies of healthy adolescents and adults. RESULTS: The forty-seven included studies encompassed 20 726 individuals plus 6526 households. Macronutrients were within WHO-recommended ranges: mean energy intake was 1867 kcal/d (95 % CI 1764, 1969) and the proportions of macronutrients were carbohydrate 61·2 % (58·4, 64·0), fat 25·3 % (22·8, 28·0) and protein 13·7 % (12·3, 15·1). The proportion of population consuming fruit and vegetables was 51·6 %; unhealthy foods, 29·4 %; and sugar-sweetened beverages (SSBs), 39·9 %. Two-thirds (68·8 %) consumed animal-source proteins. Dietary diversity scores were within the mid-range. Meal patterns were structured (typically three meals per day), with evidence lacking on snacking or eating out. CONCLUSIONS: Population-level diets fell within WHO macronutrient recommendations, were relatively diverse with structured meal patterns, but some indications of nutrition transition were apparent. The proportion of population consuming fruit and vegetables was low compared to healthy-eating recommendations, and consumption of SSBs was widespread. A paucity of evidence from 1971 to 2010 precluded a longitudinal analysis of nutrition transition. Evidence from these two countries indicates which aspects of dietary behaviours may be contributing to increasing overweight/obesity, namely a low proportion of population consuming fruit and vegetables and widespread consumption of SSBs. These are potential targets for promoting healthier diets.

The Australia New Zealand Food Standards Code does not regulate on-pack claims describing the amount of whole grain in foods. In July 2013, The Grains & Legumes Nutrition CouncilTM (GLNC) established a voluntary Code of Practice for Whole Grain Ingredient Content Claims (the Code) providing guidance for whole grain claims, with cut-off values and suggested wording ≥8 g, ≥16 g, and ≥24 g per manufacturer serve (contains; high and very high in whole grain), based on a 48 g whole grain daily target intake. The aim of this impact assessment was to report the uptake of the Code by manufacturers, changes in numbers of whole grain products, and claims on-pack since 2013, including compliance. The impact assessment was undertaken in August 2019, comparing current registered manufacturers ("users") and their products to the total number of products in the market deemed eligible for registration through GLNC product audits since 2013. Reporting included breakfast cereals, bread products, crispbreads, crackers, rice/corn cakes, rice, pasta, noodles, couscous, other grains (e.g., quinoa, buckwheat, freekeh), and grain-based muesli bars. As of 30 June 2019, there were 33 registered users and 531 registered products in Australia and New Zealand representing 43% of the eligible manufacturers and 65% of the eligible whole grain foods. Three-quarters (78% and 74%) of the eligible breakfast cereals and bread products were registered with the Code in 2019, followed by 62% of grain-based muesli bars. Only 39% of crispbread, crackers, rice/corn cakes, and rice, pasta, noodles, couscous, and other grains were registered. From 2013 there has been a 71% increase in the number of whole grain foods making claims, demonstrating strong uptake by industry, with clearer, more consistent, and compliant on-pack communication regarding whole grain content.

Marketing unhealthy foods negatively impacts children's food preferences, dietary habits and health, prompting calls for regulations that will help to create an "enabling" food environment for children. One powerful food marketing technique is product packaging, but little is known about the nature or quality of child-targeted food products over time. This study assesses how child-targeted supermarket foods in Canada have transformed with respect to nutritional profile and types of marketing appeals (that is, the power of such marketing). Products from 2009 (n = 354) and from 2017 (n = 374) were first evaluated and compared in light of two established nutritional criteria, and then compared in terms of marketing techniques on packages. Overall, child-targeted supermarket foods did not improve nutritionally over time: 88% of child-targeted products (across both datasets) would not be permitted to be marketed to children, according to the World Health Organization (WHO) criteria, and sugar levels remained consistently high. Despite this poor nutritional quality, the use of nutrition claims increased significantly over time, as did the use of cartoon characters and appealing fonts to attract children's attention. Character licensing-using characters from entertainment companies-remained consistent. The findings reveal the critical need to consider packaging as part of the strategy for protecting children from unhealthy food marketing. Given the poor nutritional quality and appealing nature of child-oriented supermarket foods, food product packaging needs to be included in the WHO's call to improve the restrictions on unhealthy food marketing to children.

Amidst the ongoing societal and economic shifts in the Eastern Mediterranean region (EMR), this study aims at investigating temporal trends in food consumption and nutrient intakes among Lebanese adults, by age and sex. Data were derived from two national cross-sectional surveys conducted in Lebanon during two time periods (1997; 2008/2009). In both surveys, dietary assessment was based on 24-h recalls. The results, expressed as % energy intake (%EI), revealed a significant decrease (p < 0.001) in the consumption of bread, fruits, fresh fruit juices, milk and eggs, whereas the consumption of added fats and oils, poultry, cereals and cereal-based products, chips and salty crackers, sweetened milk and hot beverages increased over time (p < 0.001). A significant increase in dietary energy (kcal/day) and fat intake (%EI) was observed, coupled with decreases in carbohydrate intake (%EI) and dietary density of vitamin A and vitamin C (per 1000 kcal) (p < 0.001). These changes were noted in both genders and across age groups, albeit there were some disparities between groups. In conclusion, based on national nutrition surveys, this study is the first to characterize the nutrition transition in a middle-income country of the EMR, shedding light on priority areas for nutrition policies and interventions.

Libyan women are at high risk of vitamin D deficiency, mostly due to their lifestyle and low exposure to sun. In the last decades, Libyan residents have been forced to seek refuge in countries such as Serbia, a country with high incidence of cardio-metabolic diseases. Serbian residents tend to be deficient in vitamin D, mostly due to the lack of vitamin D fortification policy. The aim of this study was to evaluate vitamin D status in Libyan adult women migrating to Serbia, with the assessment of cardio-metabolic and nutritional biomarkers, including erythrocytes fatty acid composition, magnesium concentration, and dietary intake. The same markers were measured in Serbian women, and comparisons between the groups were made. Despite low vitamin D dietary intake in both study groups, we observed lower plasma vitamin D status in Libyan women. This was accompanied by a significantly lower concentration of magnesium in Libyan women. Libyan women had significantly higher omega-3 index and lower n-6/n-3 ratio in erythrocytes' phospholipids. We observed significant negative correlation between vitamin D and n-6 polyunsaturated fatty acids (PUFA) concentrations in both study groups. Despite lower vitamin D status in the Libyan group, erythrocyte fatty acid composition, along with blood lipids' concentrations, indicated a lower cardiovascular risk. Based on our results, the discrepancy in the vitamin D status could not be ascribed to the participants' dietary intake of the micronutrient, rather is potentially associated with ethnic-specific cardio-metabolic profile, which should be confirmed in larger cohorts.

The state of nutritional health in the United States in the early part of the twentieth century was very different from today. Nutrient deficiencies and dental caries were prevalent health concerns for many Americans. In 1940, the US National Defense Advisory Commission asked the National Academy of Sciences for help in studying problems of nutrition in the United States. The outcome was issuance of the first RDAs. The goal of the RDAs was to recommend " allowances sufficiently liberal to be suitable for maintenance of good nutritional status." In the subsequent decades, a very different nutritional health challenge began to emerge for an increasing proportion of the population, that of overweight and obesity and risk of diet-related chronic disease. In part, as a response to this challenge, the RDA process was revised and the Dietary Reference Intakes (DRIs) were developed. The DRIs are a set of reference values that, when adhered to, predict a low probability of nutrient inadequacy or excessive intake. Recently, new DRI guidelines were proposed to define reference points for nutrient and food component intakes that influence risk of chronic disease. Developing DRIs for chronic disease endpoints presents unique challenges, notably, chronic diseases are multifactorial in nature and not directly nutrient-specific; the body of evidence supporting nutrients and other food substances as modifiers of risk of chronic disease is generally limited; and there is a lack of consistency in findings across study types. In addition, the latency of dietary exposures and chronic disease outcomes makes it difficult to demonstrate causality. Adapting the DRI model to meet the needs of the general population in the current context suggests a need to redefine the boundaries that describe the health of the population and to re-examine how indicators of chronic disease can be integrated effectively into the DRI process.

The International Consortium for Quality Research on Dietary Sodium/Salt (TRUE) is a coalition of intentional and national health and scientific organizations formed because of concerns low-quality research methods were creating controversy regarding dietary salt reduction. One of the main sources of controversy is believed related to errors in estimating sodium intake with urine studies. The recommendations and positions in this manuscript were generated following a series of systematic reviews and analyses by experts in hypertension, nutrition, statistics, and dietary sodium. To assess the population's current 24-hour dietary sodium ingestion, single complete 24-hour urine samples, collected over a series of days from a representative population sample, were recommended. To accurately estimate usual dietary sodium at the individual level, at least 3 non-consecutive complete 24-hour urine collections obtained over a series of days that reflect the usual short-term variations in dietary pattern were recommended. Multiple 24-hour urine collections over several years were recommended to estimate an individual's usual long-term sodium intake. The role of single spot or short duration timed urine collections in assessing population average sodium intake requires more research. Single or multiple spot or short duration timed urine collections are not recommended for assessing an individual's sodium intake especially in relationship to health outcomes. The recommendations should be applied by scientific review committees, granting agencies, editors and journal reviewers, investigators, policymakers, and those developing and creating dietary sodium recommendations. Low-quality research on dietary sodium/salt should not be funded, conducted, or published.

Pregnancy is characterized by physiological changes. One of these changes involves calcium. During this period, an increased in calcium excretion occurs as well as an increased intestinal absorption and renal reabsorption, so that the adequate growth and development of the fetus can happen. Low calcium intake is associated with chronic diseases, such as diabetes and hypertension, which have negative impact on both mother and fetus. This study aimed to evaluate the average calcium intake of high-risk pregnant women, assisted in a clinic of high complexity service and correlated with chronic diseases. To perform this study, it was used a food frequency questionnaire. As a result, high-risk pregnant women showed daily calcium intake lower than the recommended by DRI during this period. Hypertensive or diabetic pregnant women showed lower average intake of calcium. Significant association between calcium intake and nutritional status was not observed. Calcium supplementation was present, however, at low percentage in the groups with hypertensive pregnant women. To analyze the relation between calcium intake and the comorbidities, as well as calcium intake and the nutritional status of the pregnant women, it was used one-way analysis of variance and Bonferroni multiple comparison. Further studies are required for evaluating other parameters that justify the low calcium intake among this population group, and the definition of pathways for the management of the nutritional deficit considering the possible damage to maternal and neonatal health in the short and long term.

This study aims to examine whether there were changes between 1995â»2012 in the dietary glycaemic index (dGI) and glycaemic load (dGL) in Australian children (<16 years) according to three national surveys in 1995 (1995NS), 2007 (2007NS), and 2011â»2012 (2012NS). Glycaemic index (GI) values of foods were assigned using published methodology. Plausible 24-h recall data from the 1995NS, 2007NS and 2012NS (weighted n = 2475, 4373 and 1691 respectively) were compared for differences in dGI and dGL, and the contribution to dGL from different foods using one-way ANOVA with Bonferroni post hoc comparisons and linear regression. Decreasing trends across surveys were found in dGI and dGL (p < 0.001). Between 1995 and 2012, dGI and dGL per Megajoule (MJ) dropped by 2% and 6% respectively. The per capita dGL contribution from breads and bread rolls, fruit and vegetable juices, sweetened beverages and potatoes showed strong decreasing trends (R² > 0.7). Our findings suggest that dGI and dGL of Australian youths declined between 1995 to 2012, which may be due to increased awareness of the GI concept and healthy diet, widened food choices and immigrants with diverse dietary habits. This may lower the future risks of chronic degenerative diseases in Australian youths.

Dietary nitrate is increasingly linked to a variety of beneficial health outcomes. Our purpose was to estimate dietary nitrate consumption and identify key dietary changes which have occurred over time within a representative sample of Australian women. Women from the 1946â»1951 cohort of the Australian Longitudinal Study on Women's Health with complete food frequency questionnaire data for both 2001 and 2013 were included for analysis. Dietary nitrate intakes were calculated using key published nitrate databases. Diet quality scores including the Australian Recommended Food Score, the Mediterranean Diet Score and the Nutrient Rich Foods Index were calculated along with food group serves as per the Australian Dietary Guidelines. Wilcoxon matched pairs tests were used to test for change in dietary intakes and Spearman's correlations were used to examine associations. In our sample of 8161 Australian women, dietary nitrate intakes were on average 65â»70 mg/day, and we detected a significant increase in dietary nitrate consumption over time (+6.57 mg/day). Vegetables were the primary source of dietary nitrate (81â»83%), in particular lettuce (26%), spinach (14â»20%), beetroot (10â»11%), and celery (7â»8%) contributed primarily to vegetable nitrate intakes. Further, increased dietary nitrate intakes were associated with improved diet quality scores (r = 0.3, p < 0.0001). Although there is emerging evidence indicating that higher habitual dietary nitrate intakes are associated with reduced morbidity and mortality, future work in this area should consider how dietary nitrate within the context of overall diet quality can facilitate health to ensure consistent public health messages are conveyed.

BACKGROUND AND AIM: Growing evidence suggests that some of the effects of diet on cardiovascular disease (CVD) occur through mechanisms involving subclinical inflammation. We assessed the relationship between selected dietary constituents and serum high-sensitivity C-reactive protein (hsCRP) concentration in a population-based sample of United States adults. METHODS: In this cross-sectional analysis, participants were selected from the US National Health and Nutrition Examination Survey (NHANES) and restricted to those with available data on dietary intake, biochemical and anthropometric measurements from 2001 to 2010. All statistical analyses accounted for the survey design and sample weights by using SPSS Complex Samples v22.0 (IBM Corp, Armonk, NY). RESULTS: Of the 17,689 participants analysed, 8607 (48.3%) were men. The mean age was 45.8 years in the overall sample, 44.9 in men and 46.5 in women (p = .047). The age-, race-, sex-, energy intake- and body mass index-adjusted mean dietary intakes of total dietary fibre, polyunsaturated fatty-acids, vitamin E, vitamin A, vitamin B6, total folate, vitamin B family, vitamin C, vitamin K, magnesium, iron, copper and potassium monotonically decreased across increasing hsCRP quarters (p < .001 for all), whereas sugar intake increased (p < .001). In analysis of covariance adjusted for potential confounders (age-, race-, sex-, energy intake- and body weight-) hsCRP levels increased across increasing quarters of sugar intake (p < .001). CONCLUSIONS: This study provides further evidence of an association between dietary sugar, polyunsaturated fatty-acids, fibre and antioxidant intake and hsCRP levels, a subclinical inflammation marker. hsCRP concentrations are likely modulated by dietary intake. KEY MESSAGES Serum high-sensitivity C-reactive protein (hsCRP) concentration is positively associated with sugar intake, and negatively with the consumption of minerals, vitamins and polyunsaturated fatty-acids (fruit and vegetables). hsCRP concentrations, and accordingly subclinical inflammation, are likely influenced by dietary intake.

We examined temporal changes in consumer attitudes toward broad-based actions and environment-specific policies to limit sodium in restaurants, manufactured foods, and school and workplace cafeterias from the 2012 and 2015 SummerStyle surveys. We used two online, national research panel surveys to conduct a cross-sectional analysis of 7845 U.S. adults. Measures included self-reported agreement with broad-based actions and environment-specific policies to limit sodium in restaurants, manufactured foods, school cafeterias, workplace cafeterias, and quick-serve restaurants. Wald Chi-square tests were used to examine the difference between the two survey years and multivariate logistic regression was used to obtain odds ratios. Agreement with broad-based actions to limit sodium in restaurants (45.9% agreed in 2015) and manufactured foods (56.5% agreed in 2015) did not change between 2012 and 2015. From 2012 to 2015, there was a significant increase in respondents that supported environment-specific policies to lower sodium in school cafeterias (80.0% to 84.9%; p < 0.0001), workplace cafeterias (71.2% to 76.6%; p < 0.0001), and quick-serve restaurants (70.8% to 76.7%; p < 0.0001). Results suggest substantial agreement and support for actions to limit sodium in commercially-processed and prepared foods since 2012, with most consumers ready for actions to lower sodium in foods served in schools, workplaces, and quick-serve restaurants.

RESUMO Estudo de reflexão sobre as orientações nutricionais que são realizadas a população e que, na maior parte do mundo, enfatiza o consumo de frutas, verduras e legumes em maior quantidade em relação a alimentos industrializados, que por conterem maior quantidade de açúcar, sódio, e calorias aumentam o ganho de peso. No entanto, quando se lê a respeito das formas de cultivo dos alimentos in natura e sobre a qualidade dos alimentos cárneos e pescados, que são orientados para o consumo da população, surge à dúvida se há coerência entre a orientação e o consumo, uma vez que há relatos da contaminação desses alimentos por resíduos de agrotóxicos, contaminação do solo, da água e que não tem tido o devido destaque pelos órgãos estatais. Qual deveria ser a conduta perante a realidade que se apresenta? Uma perspectiva viável é a conscientização da população, que deve exigir melhores condições dos alimentos consumidos, além de resgatar práticas mais saudáveis como o cultivo de hortas orgânicas caseiras e adquirir o mínimo possível, alimentos industrializados. Longe de polemizar, esta reflexão visa incentivar uma visão crítica aos profissionais de saúde sobre seu papel na prevenção de doenças, e exigir alimentos mais saudáveis para o consumo humano.(AU)
ABSTRACT Reflection study on the nutritional guidelines given to the population, which, in most parts of the world, emphasize on the consumption of fruits, vegetables and legumes over industrialized foods, which contain more sugar, sodium and calories, and increase body weight. However, when one reads about the ways of cultivating fresh food and about the quality of meat and fish products destined for consumption, the question arises as to whether there is coherence between said guidance and consumption, given that there are reports of contamination of these foods by pesticide residues, as well as soil and water contamination, a topic scarcely addressed by state entities. What should be done to face this reality? A viable perspective is to raise awareness in the population, which should demand better quality foods, in addition to returning to healthier practices such as the cultivation of home-grown organic gardens and acquiring as few industrialized foods as possible. Far from causing controversy, this reflection aims to encourage a critical view in health professionals on their role in disease prevention and the demand for healthier foods for human consumption.(AU)
RESUMEN Estudio de reflexión sobre las orientaciones nutricionales que se dan a la población y que, en la mayor parte del mundo, enfatizan el consumo de frutas, verduras y legumbres antes que los alimentos industrializados, que por contener mayor cantidad de azúcar, sodio y calorías, aumentan peso corporal. Sin embargo, cuando se lee acerca de las formas de cultivo de los alimentos frescos y sobre la calidad de los alimentos cárnicos y pescados, destinados al consumo de la población, surge la duda de si hay coherencia entre la orientación y el consumo, dado que hay relatos de contaminación de esos alimentos por residuos de pesticidas, contaminación del suelo, del agua, poco atendido por los órganos estatales. ¿Cuál debería ser la conducta ante la realidad que se presenta? Una perspectiva viable es la concientización de la población, que debe exigir mejores condiciones de los alimentos consumidos, además de rescatar prácticas más saludables como el cultivo de huertos orgánicos caseros y adquirir el mínimo posible, de alimentos industrializados. Lejos de polemizar, esta reflexión pretende incentivar una visión crítica a de los profesionales de la salud sobre su papel en la prevención de enfermedades, y exigir alimentos más saludables para el consumo humano.(AU)
