Many additives, some of which have no nutritional value, can be legally used in processed foods. They intensify colour, thicken, increase shelf life and enhance flavour. Regulatory authorities issue approvals as safe within acceptable quantitative limits. Ultra-processed foods (UPFs) contain combinations of all these additives and are particularly attractive to children.Many publications suggest that artificial colourants, benzoate preservatives, non-caloric sweeteners, emulsifiers and their degradation derivatives have adverse effects by increasing risks of mental health disorders, attention deficit hyperactivity disorder, cardiovascular disease, metabolic syndrome and potential carcinogenic effects.A systematic review has established that artificial azo dye food colourants (AFCs) and sodium benzoate preservative cause disturbed behaviour in children. AFCs and benzoates in animal models have neurotoxic properties through gut microbial generation of toxic metabolites. Observational studies show associations between high emulsifier intake and cardiovascular disease. Animal models and in vitro studies have highlighted neurotoxic, cytotoxic, genotoxic and carcinogenic effects. High intake of non-caloric sweeteners has been linked to cardiovascular disease and depression in adults and is linked to childhood obesity.Little research has focused on children who are the largest consumers of UPFs. Potentially, they are a ticking time bomb for adult obesity, metabolic syndrome, cardiovascular diseases, mental health disorders and cancers. Based on risk/benefit analysis, azo dye AFCs should be banned. Benzoates, emulsifiers and sweeteners require assessment of quantitative limits and cumulative effects of combinations. Consumers purchasing UPFs require information through ingredient health warnings and recommendations to use natural unprocessed foods which have well-described health-promoting properties.

Soft drinks consumption is still a controversial issue for public health and public policy. Over the years, numerous studies have been conducted into the possible links between soft drink intake and medical problems, the results of which, however, remain highly contested. Nevertheless, as a result, increasing emphasis is being placed on the health properties of soft drinks, by both the industry and the consumers, for example, in the expanding area of functional drinks. Extensive legislation has been put in place to ensure that soft drinks manufacturers conform to established national and international standards. Consumers trust that the soft drinks they buy are safe and their quality is guaranteed. They also expect to be provided with information that can help them to make informed decisions about the purchase of products and that the information on product labels is not false or misleading. This paper provides a broad overview of available scientific knowledge and cites numerous studies on various aspects of soft drinks and their implications for health safety. Particular attention is given to ingredients, including artificial flavorings, colorings, and preservatives and to the lesser known risks of microbiological and chemical contamination during processing and storage.

To analyse the Na content and labelling of processed and ultra-processed food products marketed in Brazil. Cross-sectional study. A large supermarket in Florianopolis, southern Brazil. Ingredient lists and Na information on nutrition labels of all processed and ultra-processed pre-prepared meals and prepared ingredients, used in lunch or dinner, available for sale in the supermarket. The study analysed 1416 products, distributed into seven groups and forty-one subgroups. Five products did not have Na information. Most products (58.8 %; 95 % CI 55.4, 62.2 %) had high Na content (>600 mg/100 g). In 78.0 % of the subgroups, variation in Na content was at least twofold between similar products with high and low Na levels, reaching 634-fold difference in the 'garnishes and others' subgroup. More than half of the products (52.0 %; 95 % CI 48.2, 55.6 %) had at least one Na-containing food additive. There was no relationship between the appearance of salt on the ingredients list (first to third position on the list) and a product's Na content (high, medium or low; P=0.08). Most food products had high Na content, with great variation between similar products, which presents new evidence for reformulation opportunities. There were inconsistencies in Na labelling, such as lack of nutritional information and incomplete ingredient descriptions. The position of salt on the ingredients list did not facilitate the identification of high-Na foods. We therefore recommend a reduction in Na in these products and a review of Brazilian legislation.

The dietary pattern that characterizes the Western diet is strongly associated with obesity and related metabolic diseases, but biological mechanisms supporting these associations remain largely unknown. We argue that the Western diet promotes inflammation that arises from both structural and behavioral changes in the resident microbiome. The environment created in the gut by ultra-processed foods, a hallmark of the Western diet, is an evolutionarily unique selection ground for microbes that can promote diverse forms of inflammatory disease. Recognizing the importance of the microbiome in the development of diet-related disease has implications for future research, public dietary advice as well as food production practices. Research into food patterns suggests that whole foods are a common denominator of diets associated with a low level of diet-related disease. Hence, by studying how ultra-processing changes the properties of whole foods and how these foods affect the gut microbiome, more useful dietary guidelines can be made. Innovations in food production should be focusing on enabling health in the super-organism of man and microbe, and stronger regulation of potentially hazardous components of food products is warranted.

This review focuses on the potential health risks of artificial food additives, especially their effects on lung health. Preservatives, synthetic colorants, and flavor enhancers, which are commonly used in processed foods, play roles in worsening respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD). These additives cause oxidative stress, systemic inflammation, and immune dysregulation, often through the gut-lung axis. The preservatives sodium nitrite and sulfites have the risk of causing bronchial hyper-responsiveness and allergic reactions. The synthetic colorant, Ponceau 4R, is also related to immune-mediated lung inflammation. Flavoring agents such as diacetyl contribute to occupational respiratory diseases like bronchiolitis obliterans. In animal models, prenatal exposure to additives, such as titanium dioxide (E171), might disrupt the development of respiratory neural networks, with long-term consequences. Ultra-processed foods (UPFs), which also contain a high concentration of additives, lead to systemic inflammation and impair lung function. Despite their wide usage, the use of these additives has become a warning sign due to their safety issue, particularly in sensitive people like children, pregnant women, and patients with pre-existing respiratory and chronic conditions. The review highlights the serious need for strict regulation and further research on the long-term effects of food additives on respiratory health. Policymakers should ban these food additives that are more harmful to human health. As an alternative to artificial additives, natural flavors and colors from fruits and vegetables, safe preservatives, and minimally processed ingredients can be used.

BACKGROUND: In South East Asia, concerns exist about the acceptability of peanut-based Ready-to-Use-Therapeutic-Foods (RUTF) for the treatment of severe acute malnutrition (SAM). Therefore, an alternative, culturally acceptable RUTF made from locally available ingredients and complying with local food traditions and preferences was developed. The current study evaluated its acceptability and impact on anthropometry. METHODS: The study was a randomized, two-arm, cross-over intervention trial to test the acceptability of the local product (bar) against a commercially available, peanut-based RUTF paste (Plumpy’nut®). Children (n = 67) from two kindergartens in a rural area of North Vietnam were recruited. The age of the children was between 3 and 5 years. RESULTS: The Vietnamese RUTF was well-accepted, although overall acceptability was less than of Plumpy’nut®, with the latter scoring higher on palatability (P < 0.05). In contrast, reluctance to eat Plumpy’nut® was higher than for the Vietnamese RUTF (P < 0.05). Impact on anthropmetrical indices was similar for both RUTF. The nutritional status of the children who consumed the two RUTF over a 4 week period improved significantly, with a mean weight gain of 0.64 (SD 0.27) Kg, and increases in WHZ and HAZ z-scores of 0.48 (SD 0.30) and 0.05 (SD 0.13) respectively (P < 0.01 both). Weight gain was similar between the 2 products (0.32 kg per 2 weeks for both). CONCLUSIONS: Both the commercial Plumpy’nut® and the local produced RUTF were accepted although the harder consistency of the local product might have caused the lower overall acceptance. The promising increase in nutritional status needs to be confirmed in a controlled trial in children with SAM.

Scientific evidence of the association between free sugar consumption and several adverse health effects has led many public health institutions to take measures to limit the intake of added or free sugar. Monitoring the efficiency of such policies and the amount of free sugar consumed requires precise knowledge of free sugar content in different food products. To meet this need, our cross-sectional study aimed at assessing free sugar content for 10,674 pre-packaged food items available from major Slovenian food stores during data collection in 2015. Together, 52.6% of all analyzed products contained free sugar, which accounted for an average of 57.5% of the total sugar content. Food categories with the highest median free sugar content were: honey and syrups (78.0 g/100 g), jellies (62.9 g/100 g), chocolate and sweets (44.6 g/100 g), jam and spreads (35.9 g/100 g), and cereal bars (23.8 g/100 g). Using year-round sales data provided by the retailers, the data showed that chocolate, sweets, and soft drinks alone accounted for more than 50% of all free sugar sold on the Slovenian market. The results of this study can be used to prepare more targeted interventions and efficient dietary recommendations.

Purpose: There is concern about the nutritional quality of processed gluten-free (GF) products. The aim was to investigate the nutrient composition and cost of processed GF products compared with similar regular products. Methods: Product size, price, caloric value, and macro- and micronutrient composition were compared between foods labeled “Gluten-free” and comparable regular products in 5 grocery stores in 3 Canadian cities. Data were calculated per 100 g of product. Results: A total of 131 products were studied (71 GF, 60 regular). Overall, calories were comparable between GF and regular foods. However, fat content of GF breads was higher (mean 7.7 vs. 3.6 g, P = 0.003), whereas protein was lower (mean 5.0 vs. 8.0 g, P = 0.001). Mean carbohydrate content of GF pasta was higher (78 vs. 74 g, P = 0.001), whereas protein (7.5 vs. 13.3 g, P < 0.001), fibre (3.3 vs. 5.8 g, P = 0.048), iron (9% vs. 25%DV, P < 0.001), and folate content (5% vs. 95%DV, P < 0.001) were lower. Mean price of GF products was$1.99 versus $ 1.23 for regular products (P < 0.001). Conclusions: Some commonly consumed packaged GF foods are higher in fat and carbohydrates and lower in protein, iron, and folate compared with regular products. GF products are more expensive. Dietitians should counsel patients on the GF diet regarding its nutritional and financial impact.

Foodborne non-typhoidal salmonellosis causes approximately 1 million illnesses annually in the USA. In April 2015, we investigated a multistate outbreak of 65 Salmonella Paratyphi B variant L(+) tartrate(+) infections associated with frozen raw tuna imported from Indonesia, which was consumed raw in sushi. Forty-six (92%) of 50 case-patients interviewed ate sushi during the week before illness onset, and 44 (98%) of 45 who specified ate sushi containing raw tuna. Two outbreak strains were isolated from the samples of frozen raw tuna. Traceback identified a single importer as a common source of tuna consumed by case-patients; this importer issued three voluntary recalls of tuna sourced from one Indonesian processor. Four Salmonella Weltevreden infections were also linked to this outbreak. Whole-genome sequencing was useful in establishing a link between Salmonella isolated from ill people and tuna. This outbreak highlights the continuing foodborne illness risk associated with raw seafood consumption, the importance of processing seafood in a manner that minimises contamination with pathogenic microorganisms and the continuing need to ensure imported foods are safe to eat. People at higher risk for foodborne illness should not consume undercooked animal products, such as raw seafood.

The gut microbiota plays a key role in health and disease, but it could be affected by various factors (diet, lifestyle, environment, genetics, etc.). Focusing on diet, while the role of the different styles and choices (Mediterranean vs. Western diet, vegan or vegetarian diets) has been extensively studied, there are a few comprehensive papers on the effects of additives and food processing. Therefore, the main goal of this manuscript is to propose an overview of the link between ultra-processed foods and the gut microbiota based on papers and data available in the literature. The literature search was performed on PubMed and Clinicaltrials.gov, and after the selection of the most relevant articles, the paper proposes a synopsis of the effects of some classes of additives (sweeteners, preservatives, emulsifiers, glutamate, etc.), as well as of some treatments, on the gut microbiota and some pathological conditions.
