Background: The relationship between sports participation and food preferences in adults, as well as the influence of gender, is still unclear. Objective: The objective of this study was to investigate the association between sports participation and individual food preferences and to explore potential gender differences among sports participants in a large group of Italian adults. Methods: This cross-sectional study involved 2665 adults (aged ≥ 18 years) who lead normal lives and underwent a routine lifestyle and dietary assessment at a clinical centre specialising in nutrition, metabolic health, and lifestyle counselling in Rome. Participants completed an online questionnaire on food preferences (19 foods) and sports practice. Multivariate logistic regression models, adjusted for age, sex, and smoking, were used to assess associations. Results: Sports participation was defined as engaging in structured physical activity at least once per week and was reported by 53.5% of subjects (men: 60.1%; women: 49.0%; p < 0.0001). After adjustment, active individuals were significantly more likely to prefer plant-based drinks, low-fat yoghurt, fish, cooked and raw vegetables, fruit, whole grains, tofu, and dark chocolate (all p < 0.05) and less likely to prefer cow’s milk (p = 0.018). Among sport participants, males were more likely to prefer meat (general, white, red, processed) and eggs, while females preferred plant-based drinks. No significant gender differences were observed for dairy products, legumes, or fish. Differences in food preferences were also observed according to the type of sport, with bodybuilders showing higher preference for tofu and dark chocolate. The strongest associations were found in the 25–44 age group. Conclusions: Sports participation is independently associated with specific food preferences, characterised by greater preference for plant-based and fibre-rich foods, and gender differences in food choices persist even among active adults. These findings highlight the need to consider both sports participation and gender when designing nutritional interventions. Full article

We have previously shown a difference between the gut microbiota composition of stunted and non-stunted children in East Nusa Tenggara, Indonesia. The current study aimed to perform an intervention with a probiotic, Lactiplantibacillus plantarum IS-10506, and its UHT-treated postbiotic compared to placebo in order to accomplish catch-up growth in the stunted children, possibly through modulation of the gut microbiota. Apart from the maltodextrin (placebo), probiotic, and postbiotic in chocolate milk, all groups also received a functional and nutritional biscuit and had access to newly constructed water wells as well as soap to improve hygiene. The results show that independent of treatment, the stunted children had a significantly higher increase in height and zlen (corrected for age) compared with their age- and gender-matched controls but a significantly lower increase in weight. Several potential pathogenic taxa declined in all groups, among which was Escherichia/Shigella (adjusted.p = 6.44 × 10⁻¹⁵), but so did some beneficial taxa, such as Bifidobacterium and Akkermansia. Faecalibacterium, which was already higher in the stunted children at baseline, increased independent of treatment. Changes in the relative abundance of several taxa of the microbiota correlated with the changes in anthropometric measures. In conclusion, although there was no difference between the interventions, understanding the dynamics and the role of the gut microbiota in this process might allow healthcare providers to develop targeted nutritional strategies aimed at optimizing health outcomes for children at risk of stunting, thereby addressing a critical global health issue.

Background: Cow’s milk is the most frequent cause of food allergies in children, with caseins and β-lactoglobulin being considered the main allergens. Concerningly, numerous international agencies have highlighted a growing risk of allergic reactions in milk-allergic individuals after the consumption of products labelled as “vegan”. Objectives: We describe the case of a 3.5-year-old boy with a history of a food allergy to milk who complained of anaphylactic clinical symptoms after eating a vegan Easter egg. The aim of this study was to confirm the cause of the clinical symptoms, searching for the possible presence of milk proteins in the vegan chocolate. Methods: An experimental approach based on electrophoretic (SDS-PAGE) and immunoenzymatic techniques (ELISA) was applied. Results: SDS-PAGE indicated the presence of milk proteins, which was confirmed and quantified via ELISA (3034 ± 115 mg/kg). Conclusions: The data obtained demonstrate that the severe clinical symptoms were due to the unexpected presence of milk proteins in a vegan product, underlining the critical need for rigorous allergen quality control throughout the food industry.

Chocolate is one of the most popular and widely consumed confectionery products. However, elevated cadmium (Cd) content in this commodity threatens food safety and human health. It is crucial to monitor the presence of Cd in chocolate and to evaluate its associated health risks. This study assessed the Cd levels in milk and dark chocolates from the Serbian market (n = 155). Cadmium concentrations varied between 0.010 and 0.29 mg/kg. The obtained values were used to evaluate the hazard quotient (HQ) and cancer risk (CR). The estimated weekly intakes (EWIs) were below the tolerable limits for all samples. However, in some samples, the EWI reached 60.9% and 63.5% of the tolerable limit for toddlers and other children, respectively. No health risk was found based on the HQ. On the other hand, based on CR values, all chocolate products can be classified as posing a moderate risk. The Monte Carlo simulation indicated that toddlers and other children were more exposed to non-carcinogenic risk, whereas vegetarians, adults, pregnant women, and other children were more exposed to cancer risk. Sensitivity analysis indicates that body weight, exposure frequency, and ingestion rate are the most influential factors for non-cancer and cancer health risks. Full article

This study compares the rheological, thermal, and textural characteristics of four types of chocolate—white, milk, ruby, and dark—produced by the same manufacturer. White, milk, and ruby chocolates contain 36% fat, while dark chocolate has 39%. Cocoa content varies from 28% in white, 33% in milk, 47% in ruby, to 70% in dark chocolate. Rheological properties were assessed with a rotational rheometer, while density was measured with a gas pycnometer. Particle size distribution (PSD) was evaluated using laser diffraction, and thermal properties were analyzed with differential scanning calorimetry (DSC). The DSC results indicated that enthalpy increased with cocoa content, whereby dark chocolate showed the highest value (55.04 J g⁻¹) and white chocolate the lowest (35.3 J g⁻¹). PSD followed a monomodal pattern; dark chocolate had the smallest particles, leading to the highest hardness. Density ranged from 1.2773 to 1.2067 g∙cm⁻³. The results from classical rotational rheological measurements were in accordance with oscillatory measurements. Rheological measurements confirmed that the Casson yield stress was the highest for milk chocolate (17.61 Pa). The viscosity values decreased with increasing shear rate for all chocolates. All chocolate samples showed strong shear-thinning behavior up to a 100 s⁻¹ shear rate. Oscillatory measurements showed the paste-like nature of all samples, i.e., storage modulus G’ dominates loss modulus G’’ at small shear stress values, and the complex modulus G*, which represents the stiffness, varied as follows: milk > white > dark > ruby. This study offers valuable insights into the properties of chocolates during production and storage, helping manufacturers anticipate key characteristics for new confectionery products. Full article

The war in Ukraine and the related disruptions in its supply chains shook global markets for agricultural and energy commodities, causing their prices to increase to unprecedented levels. At the same time, this situation highlighted the fact that Ukraine is an important global producer and exporter of certain agricultural products. The complete opening of the EU market to duty-free imports from Ukraine showed that Ukrainian products constitute competition for both EU and Polish food producers. This, in turn, caused further disruptions in the food supply chains within the EU. The aim of this article is to assess the competitive position of Polish and Ukrainian food producers in the EU market and the prospects for the evolution of their competitive advantages. The analysis was carried out using selected quantitative indicators of competitive position, namely Balassa’s Revealed Comparative Advantage Index (RCA) and the Trade Coverage Index (TC). The calculations were made using statistical data from the World Bank WITS-Comtrade database. The research covered the period from 2018 to 2023, inclusive. The research shows that between 2018 and 2023, the share of products in Polish exports to the EU, in which both countries compete, increased to 37.5%; that is, both countries had comparative advantages in these products on this market. The current competition includes, among others, poultry meat, bakery products, wafers and cookies, chocolate, corn, fruit juices, frozen fruit, water and other non-alcoholic drinks, and wheat. At the same time, more than half of Polish exports consisted of products that may become the subject of such competition in the future (currently, only Poland has comparative advantages in the export of these products). These may include, among others, cigarettes, animal feed, fresh or chilled beef, other food products, smoked fish, canned meat, fish fillets, pork, canned fish, and liquid milk and cream. Therefore, Polish food producers face big challenges; the process of the post-war reconstruction of Ukraine and its potential integration with the single European market will strengthen the competitive position of Ukrainian food producers in the EU market. The current competitive strategy of Polish producers, based on cost and price advantages, may turn out to be ineffective under these conditions. Therefore, they must look for new sources of competitive advantage that will distinguish Polish products from the cheaper Ukrainian ones. Therefore, a strategy of competing on quality may prove effective. Full article

Product development must be continuously done by the chocolate industry to face a high level of competitiveness in the market industry. This study investigates the effect of powdered sappan wood and butterfly pea flower incorporation in milk and white chocolate compounds. Four concentrations of each additional ingredient were used (0, 5, 10 and 15%). The results show that incorporating powdered sappan wood and butterfly pea flower significantly improved the total phenolic and flavonoid content and antioxidant activity of milk and white compounds. This study clearly shows that the selected plant could be an alternative to improve the health-promoting properties of milk and white chocolate compounds. However, supplementation also has some drawbacks, particularly in increasing the moisture content and the degree of colour difference between the milk and white compounds containing additional ingredients and the control. Also, powdered sappan wood and butterfly pea flower caused a higher viscosity of milk and white chocolate compounds. The results obtained in this study create a new strategy for using sappan wood and butterfly pea flower in various food products. Full article

During food quality control, NIR technology enables the rapid and non-destructive determination of the typical quality characteristics of food categories, their origin, and the detection of potential counterfeits. Over the past 20 years, the NIR results for a variety of food groups—including meat and meat products, milk and milk products, baked goods, pasta, honey, vegetables, fruits, and luxury items like coffee, tea, and chocolate—have been compiled. This review aims to give a broad overview of the NIRS processes that have been used thus far to assist researchers employing non-destructive techniques in comparing their findings with earlier data and determining new research directions.

The increasing demand for functional and nutritious beverages necessitates the exploration of novel ingredients and formulations. This study evaluated the impact of supplementing chocolate milk with desert truffles powder and varying concentrations of gum arabic on its chemical composition, viscosity, color characteristics, antioxidant activity, and sensory attributes. Desert truffles powder was consistently incorporated at 2% across all treatments, while gum arabic concentrations varied from 0% to 1.5%. The results revealed significant enhancements in the nutritional profile, particularly in treatments with higher gum arabic concentrations, which showed increased solids-not-fat, protein, and carbohydrate contents. Additionally, the viscosity and shear stress values of the chocolate milk improved with the addition of gum arabic, enhancing its texture and stability. Color analysis demonstrated a darker and more intense coloration in samples with higher gum arabic levels. Antioxidant activity, assessed through total phenolic content, DPPH, and ABTS scavenging activity, was highest at moderate gum arabic concentrations but declined at higher levels. A high correlation was observed between total phenolic content and both DPPH and ABTS scavenging activities. Sensory evaluation indicated no significant differences in flavor, consistency, color, and overall acceptability across treatments, suggesting that the nutritional enhancements did not compromise sensory qualities. Overall, this study highlights that incorporating desert truffles powder and gum arabic can effectively improve the functional and nutritional properties of chocolate milk, presenting it as a viable option for health-oriented consumers.

Complementary feeding (CF) may influence later eating behaviour and growth. Our previous Randomised Control Trial (RCT) reported that new CF guidelines (NCFGs) implemented in 6–12-month-old infants in Bogota, Colombia, had positive short-term effects on red meat, vegetable and fruit consumption. Here, we assessed the effects of the NCFGs on food consumption, eating behaviour and growth at 6 years of age. Weight and height were measured using 50 children (58.8%) from the cohort. Feeding behaviour was measured using the Child Eating Behaviour Questionnaire (CEBQ) and maternal and child food consumption was measured using a semi-quantitative food frequency questionnaire. The control group (CG) had a significantly higher weekly consumption of chocolate milk drinks (p = 0.05). The mean food responsiveness (FR) score was significantly higher in the CG (p < 0.001). Although HAZ (height for age Z-score) at 6 years of age was significantly higher in the CG (p < 0.02), there was no significant difference between groups in the change in HAZ from 6 months and 12 months to 6 years of age. BMIZ (body mass index Z-score) and % overweight (CG 18.5% versus NCFG 13%) or obese (3.7% versus 0%) were not significantly different between groups. BMIZ was positively predicted by FR (β 0.293; p = 0.014) and negatively predicted by weekly red meat consumption episodes per week at 12 months (β −0.169; p = 0.020). Although there was no direct effect of an intervention on BMIZ at 6 years of age, the results were consistent with an indirect effect via intervention effects on meat consumption at an age of 12 months and FR at 6 years of age. However, further longitudinal studies with a larger sample size are needed. Full article

Chocolate-flavored milk contributes to excessive intake of added sugars among children and adolescents, which why it is a good candidate product for sucrose replacement. This study investigates how replacing sucrose partially or completely with different sweetener systems affects the sensory profile and consumer liking. Five chocolate-flavored milk treatments were formulated, varying in sucrose replacement level (partial: 58%; complete: 100%) and sweetener system (synthetic: acesulfame-K; natural: rebaudioside M-erythritol blend). Relative-to-Reference Scaling by a trained panel confirmed that no significant differences in the sensory profile when partial sucrose replacement was compared to sucrose, whereas the complete replacement increased bitter taste, pungent flavor, licorice flavor and mouth-drying. A total of 104 consumers evaluated the treatments for liking and indicated their temporal perceptions with temporal check-all-that-apply. Latent variable clustering performed on liking ratings revealed two clusters, which perceived temporal sensory characteristics differently depending on the sweetener system. Cluster 1 preferred the sucrose control over treatments with complete and partial replacement using a natural sweetener system, with complete replacement being perceived as having off-flavor. Cluster 2 preferred the sucrose control over partial and complete replacement using either of the sweetener replacements investigated, which were characterized as off-flavored and bitter. Understanding these consumer segments enables the food industry to develop effective low-energy formulations using synthetic and natural non-nutritive sweeteners, leading to reduced sugar consumption.

Chocolate is a popular food for its unique flavor and taste, rich nutritional value, and the psychological values brought to people. The raw material production of chocolate, product manufacturing, sales and transportation have different degrees of environmental impact. This review explores the environmental hot spots in the life cycle of chocolate and puts forward corresponding suggestions for the improvement. By applying a systematic review method, this paper collected 25 articles on life cycle assessment (LCA) of the environmental impact of the chocolate industry. It is found that the life cycle of chocolate has the highest environmental impact in the raw material production and chocolate manufacturing stages (accounting for 77–97% of total impacts), among which milk powder, sugar and cocoa derivatives are the important contributors to significant environmental burden. Dark chocolate generates the lowest carbon emissions (1.67 kg CO₂ eq/kg product) among existing chocolate categories, while the chocolate confectionery products release the highest carbon emissions (6.76 kg CO₂ eq/kg product) among chocolate-containing products. Improvement measures are proposed for reducing environmental impacts and for selecting environmentally friendly product formulae. This study can provide benchmarking for the chocolate industry and improves the understanding of life cycle environmental impacts of chocolate products. Full article

Eating behaviour (EB) is a complex system affected by different factors, including food liking and psychology. Researchers have highlighted the importance of genetics in EB, but little is known. Therefore, this study aimed to investigate the genetic factors involved in EB in Italian cohorts, Friuli-Venezia Giulia (FVG) and Val Borbera (VB). Genome-Wide Association Studies (GWAS) on food liking were performed in FVG (n = 575). The relationships between the genetic findings and other variables of interest (i.e., psychological outcomes) were evaluated using linear regression models. A replication study was carried out in an independent cohort (VB, n = 701). GWAS revealed a significant association between the liking of milk chocolate and a region on chromosome 5. The most associated single nucleotide polymorphism (SNP) was rs73280705 (p = 1.02 × 10⁻⁹), an eQTL for the LARP1 gene in the nucleus accumbens (NAc). Subjects carrying the minor allele of the SNP show a reduced liking for milk chocolate, as well as a minor overall liking for a milk-based food group. The latter finding was replicated in VB (p = 0.026). Regarding the psychological data, these subjects also present a reduced impulsivity (p = 0.031). On the other hand, carriers of the counterpart allele show an increased liking for milk-based food and a high impulsivity (p = 0.023). These data are not influenced by the lactose deficiency allele. The results suggest that this genetic region could play a role in both impulsivity and food liking. Indeed, individuals carrying the LARP1 gene variant show a decrease in liking for milk chocolate and milk-based food, as well as in impulsivity, while the others are more impulsive, like more milk-based foods and, in general, sweet and fatty foods. LARP1 is expressed in the NAc, which is a central driver of reward response controlling the pleasantness and gratification given by food (mostly triggered by highly palatable foods). Moreover, the NAc also plays a role in integrating limbic system stimulation into the motor system, which can lead to addictive and impulsive behaviours. Additional studies are needed to increase our knowledge on this extremely interesting gene association and, overall, on the LARP1 gene’s relationship with milk and mTORC1, food liking, and EB.

The texture of a particular food product has great significance for the sensory perception of its overall quality. When it comes to chocolate, texture as hardness plays an important role not only for visual evaluation (surface appearance), but also for the sensory perception of chocolate melting in the mouth. This feature is affected by many factors, whereas the composition of chocolate (particularly fat content), the size and distribution of solid particles, as well as the storage temperature are the prime ones. The aim of this experiment was to test the texture of chocolate, depending on its type (white, milk, and dark) stored at three different temperatures (16, 20, and 25 °C), which is the most typical consumption temperature range. The texture of the chocolate samples was examined instrumentally using a texture analyzer and through sensory analysis carried out by skilled panelists. The obtained results showed that the influence of the storage temperature and the type of chocolate has a statistically significant impact on chocolate’s hardness when determined by instrument, while in sensory evaluation, the type of chocolate is a predominant influencing factor. The hardness of chocolate was the lowest in white chocolate samples, and it decreased at higher storage temperatures, as expected. The sensory perception of chocolate melting was notably affected by the chocolate hardness. The general outcomes of the study have shown that there is a positive correlation between instrumental and sensory analysis methods. Full article

Milk protein dispersions containing added cocoa powder (1.5% (w/w)) and sucrose (7% (w/w)) and varying levels of κ-carrageenan (0.01, 0.03, or 0.05% w/w) were subjected to combined heat treatment (90 °C/5 min or 121 °C/2.6 min) and shear (100 or 1000 s⁻¹) to investigate the heat stability of milk proteins. The application of shear led to a notable reduction in non-sedimentable proteins, resulting in an increase in the average particle size and apparent viscosity of the dispersions, particularly at high concentrations of k-carrageenan and elevated temperatures. This indicates that shear forces induced prominent protein aggregation, especially at higher κ-carrageenan concentrations. This aggregation was primarily attributed to the destabilisation of micelles and presence of loosely bound caseins within the κ-carrageenan network, which exhibited increased susceptibility to aggregation as collision frequencies increased due to shear.
