Objectives: This study aimed to assess salt and sugar-related knowledge, attitudes and behaviours (KAB) of adults in the Central Division of Fiji. Methods: A randomised stratified sample of 700 adults were selected. Questions on salt and sugar-related KABs were developed. The survey took place from March to June 2022. For analyses, population and sample weights were applied, and differences between predefined subgroups (sex, age, ethnicity and area) were compared using weighted chi-square tests. Results: 534 adults participated (response rate 76%). Over 80% of participants (82% (95% CI 78.5 to 84.9%)) identified that consuming too much salt or salty sauce can lead to hypertension. More than 90% recognised that consuming too much sugar can lead to diabetes (92.3% (89.7 to 94.3%)). Approximately 80% of participants thought it was somewhat or very important to lower salt and sugar intake in their diet (79.8% (76.1 to 83.0) and 84.2% (80.8 to 87.1%), respectively). However, almost 40% reported adding salt or salty sauces when cooking (37.3% (32.7 to 42.2%)) and 65% (60.6 to 68.5%) adding sugar to drinks daily. Conclusions: Despite having positive knowledge and attitudes, many people reported behaviours likely to contribute to excess salt and sugar intake, highlighting the need for interventions that support behaviour change and the creation of healthier food environments.

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.

This study investigates the implicit and explicit health–taste tradeoffs that consumers make in response to sugar‐reduction claims on chocolate cereals. We collect implicit measures through an Implicit Association Test, explicit perceptions of health and taste properties, and statements regarding product liking and purchase intention through a questionnaire. Based on a path analysis, we assess the relative strength of the indirect effects of sugar‐reduction claims mediated by health and taste perceptions, as well as the direct effects on purchase intention. The results indicate that sugar‐reduction claims decrease taste perceptions, increase health perceptions, and have only minor negative effects on product liking, but increase purchase intentions. Most participants show an implicit "unhealthy = tasty" intuition, which can be offset by moderate to high health consciousness. The implications for marketing and policymakers are twofold. First, our study shows that sugar‐reduction claims are effective in addressing the original target group of health‐conscious consumers. Second, our results suggest that the health–taste tradeoff is not prohibitively detrimental to purchase intentions among less health‐conscious consumers. Potential instruments to increase the market share in this segment are discussed [EconLit Citations: I18, D12, D83]. [ABSTRACT FROM AUTHOR]

Consumer concern about intake of added sugars has increased commercial demand for sugar‐reduced chocolates. However, substitution with high‐potency sweeteners is not possible as sugar serves as an important bulking agent. Here, we investigated replacement of sucrose in chocolate compound with oat or rice flours, with starch granules smaller than 10 µm, focusing on texture, sweetness, and acceptability. In Study 1, six chocolates were made: a control with 54% sucrose, four sucrose‐reduced versions (reductions of 25% or 50%, using either oat or sweet rice flour), and one 54% sucrose chocolate with reduced refining time. These chocolates were compared in a Difference from Control (DFC) test in a within‐subject design, with and without nose clips. Particle size distribution, yield stress, and plastic viscosity were measured. Chocolates with 25% sucrose reduction by either sweet rice or oat flour (or reduced refining time) were not significantly different from the blind control (p > 0.05), regardless of nose clip use. In open‐ended comments, participants reported differences in rice‐flour‐containing chocolates were due to a chalkier texture, while oat‐flour‐containing chocolates were described as smoother, softer, and creamier. DFC scores from the chocolates were positively correlated with plastic viscosity and negatively correlated with yield stress. In Study 2, 25% reduced sugar chocolates made with rice flour were liked significantly less than control, but the oat flour sample did not differ from control. Collectively, these results suggest up to 25% of sucrose in chocolate can be replaced with oat flour without negatively affecting texture or consumer acceptance. [ABSTRACT FROM AUTHOR]

BACKGROUND: Excessive sugar consumption has been linked to type 2 diabetes, obesity and other diseases. Therefore, it is indispensable to reduce sugar of food. However, the sensory characteristics of food are affected after sugar reduction (SR). Currently, SR has been reported in drinks, jams, candies, and other fruit related or sweet foods; but salty or protein related foods have not been explored, therefore there is a big gap that needs to be filled. RESULTS: Sensory scores of initial sweetness and sweetness reduced by 0.26 and 0.12 in 10% SR dried fish mince product compared with control, and there was a small difference between 25% SR (3.33) and 40% SR (3.09) samples. It also showed that 10% SR sample had a small reduction in sweetness value and free sugar content by 3.5% (0.42/11.9) and 7.8% (2.12/27.06) compared with control; while values in 25% SR sample decreased sharply but were not much different from 40% SR sample. Electronic nose results showed that SR had a small effect on odor. Texture analysis showed that texture properties of 25% SR sample were significantly different from control. CONCLUSIONS: Dried fish mince product with below 10% SR had a small difference on the sensory characteristics and there was a big change when SR was more than 20%. Dried fish mince product with 25% SR and 40% SR had no significant difference. SR had a small effect on odor, but had a great effect on texture properties, especially over 20% SR. © 2023 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

In this study, the effect of reducing the sugar (50%, 100%) and fat (50%, 75%) content on the physical and sensory properties of cupcakes was investigated by using stevia and polydextrose as sugar and fat replacers, respectively. While reducing the fat content increased the density of the cake batter, it caused a decrease in the consistency values such as firmness, consistency, cohesiveness and viscosity index. Reducing the sugar content had the opposite effect, decreasing the batter density and significantly increasing the batter consistency. Reducing only sugar and only fat content showed better results than control, while reducing both sugar and fat content together negatively affected the textural properties of cakes. In general, reducing only sugar content decreased sensory satisfaction compared to reducing only fat content. The samples with only 50% reduced fat content were most liked in terms of all sensory parameters. It was concluded that only sugar or only fat contents can be reduced by 50% in cake production, especially considering the specific volume, textural and sensory properties. [ABSTRACT FROM AUTHOR]

The pigment extract from purple carrot with high sugar is prone to microbial contamination and anthocyanidin deterioration. Effective desugar of natural pigment extracts is essential for improving product quality. This work aimed to design a yeast fermentation process to reduce sugar in the concentrated juice from purple carrot. The effects of fermentation parameters such as temperature, initial pH, and initial sugar content on the sugarremoving rate were analyzed via single-factor and response surface analysis. Results showed that the maximum desugar rate of 91.03% was obtained under the optimal conditions of initial pH 3.2, temperature 30°C, and initial sugar content of 160 g/L, which was similar with model predictions. Subsequently, to broaden the application of purple carrots, the fermentation process of purple carrot vinegar was investigated using the resulting fermented juices with low sugar as raw material. The fermentation broth was treated and inoculated with Acetobacter pasteuriana AS1.41. The optimized conditions were found as temperature of 30°C,, pH 4.2, and inoculation amount of 8%. The corresponding acetic acid content was 35.62 g/L. The work has thus provided new insights into the development of natural food additives. [ABSTRACT FROM AUTHOR]

The current levels of added sugars in processed foods impact dental health and contribute to a range of chronic non-communicable diseases, such as overweight, obesity, metabolic syndrome, type 2 diabetes, and cardiovascular diseases. This review presents sugars and sweeteners used in food processing, the current possibility to replace added sugars, and highlights the benefits of using dates as a new natural, nutritious and healthy alternative to synthetic and non-nutritive sweeteners. In the context of environmental sustainability, palm groves afford a propitious habitat for a diverse array of animal species and assume a pivotal social role by contributing to the provisioning of sustenance and livelihoods for local communities. The available literature shows the date as an alternative to added sugars due to its composition in macro and micronutrients, especially in bioactive components (fiber, polyphenols and minerals). Therefore, dates are presented as a health promoter and a preventative for certain diseases with the consequent added value. The use of damaged or unmarketable dates, due to its limited shelf life, can reduce losses and improve the sustainability of date palm cultivation. This review shows the potential use dates, date by-products and second quality dates as sugar substitutes in the production of sweet and healthier foods, in line with broader sustainability objectives and circular economy principles.

This review highlights Leuconostoc citreum's promising possibilities as a proficient mannitol producer and its potential implications for sugar reduction, with a focus on its use in sourdough-based baked good products. Mannitol, a naturally occurring sugar alcohol, has gained popularity in food items due to its low calorie content and unique beneficial qualities. This study summarizes recent research findings and investigates the metabolic pathways and culture conditions that favor increased mannitol production by Leuconostoc citreum. Furthermore, it investigates the several applications of mannitol in baked goods, such as its function in increasing texture, flavor and shelf life while lowering the sugar content. Sourdough-based products provide an attractive niche for mannitol integration, as customer demand for healthier and reduced-sugar options increases. [ABSTRACT FROM AUTHOR]

The impact of sugary foods on public health has contributed to the development of low‐sugar and sugar‐substituted products, and sugar reduction has become a major challenge for the food industry. There is growing empirical evidence that odor can enhance the perception of sweetness without increasing the caloric load. This current review summarizes the researches on odor‐induced sweetness enhancement published in recent years and discusses the mechanisms and influencing factors of odor‐sweetness interactions. In addition, by combing existing studies, this paper also summarizes the research methods and strategies to investigate odor‐induced sweetness enhancement. Finally, the feasibility of synergistic enhancement of sweetness through the superposition of odor with other senses (texture, visual, etc.) is also discussed and analyzed. In conclusion, odor‐induced sweetness enhancement may present an alternative or complementary approach for developing foods with less sugar. [ABSTRACT FROM AUTHOR]

ABSTRACTSweet egg yolk drops are one of the traditional Thai desserts made by dropping egg yolk batter into a boiling syrup with high sugar concentration to form teardrop shapes. The objectives of this study were to optimize the ratio of sugar substitutes (sorbitol and fructooligosaccharides (FOS)) and reduce the amount of sugar in syrup for the development of sugar-reduced egg yolk desserts. Effects of three ratios of sorbitol to FOS (25:75, 50:50, and 75:25) and four percentages of sugar reduction (25, 50, 75, and 100%) on the physical, chemical and sensory properties of desserts were also investigated. Results indicated that increasing the ratio of sorbitol and decreasing the percentage of sugar in syrup led to desserts with decreased color a* and b* values, bulk density, hardness, cohesiveness, soluble fiber, and reducing-sugar content. The opposite effect was observed in desserts made with syrup, which had higher ratios of FOS and lower levels of sugar. The optimum formulation of desserts based on response surface methodology (RSM) contained a ratio of 25:75–30:70 of sorbitol to FOS and 60–65% reduction of sugar in syrup. The comparison of the predicted values from the model of the optimized dessert with experimental values showed that the model was well-fitted. Moreover, the optimized dessert had higher sensory acceptability when compared to the full-sugar sweet egg yolk drops. Therefore, the results indicate that sorbitol and FOS could be used as sugar substitutes in syrup to produce a healthier and lower calorie egg-based dessert.

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.

Excessive sugar consumption in young people, who are the major consumers of sugary drinks, combined with limited physical activity, is an important determinant of obesity. Despite their natural appeal, fruit juices have a similar sugar content to that of sugary drinks and once metabolized, they may induce the same biological response. This study aimed to verify whether fermentation processes can make juice consumption healthier and whether reduced-sugar juices have a specific impact on intestinal function. We designed a tailored fermentation of apple-pear juices with lactic acid bacteria and yeasts, which resulted in a reduction of sugar content (27–66%) and caloric intake, and an increase in mannitol content. The impact of newly developed apple-pear juices on gut microbiome composition and functionality was evaluated in vitro using the Simulator of the Human Intestinal Microbial Ecosystem (SHIME). Promising changes were found in the gut microbiota and its metabolic responses and functionality, targeting pathways related to obesity and weight loss (lipopolysaccharide and secondary metabolite biosynthesis, polycyclic aromatic hydrocarbon degradation, and amino sugar and nucleotide sugar metabolism). Additionally, the fermented apple-pear juices positively modulated the intestinal epithelial features. While the simulation of the study simplifies the complex in vivo conditions, it suggests that low-sugar fermented apple-pear juices can elicit targeted responses in the gut ecosystem, contributing to healthier alternatives to traditional fruit juices.

The Childhood Obesity Plan aimed to reduce sugar and energy in foods through a voluntary sugar-reduction programme. Our primary objective was to determine whether this implementation strategy had been successful, focusing on the out-of-home sector. We used a repeated cross-sectional design to evaluate nutritional changes in desserts served by leading chain restaurants. We extracted nutrition information from online menus in autumn/winter 2020, for comparison with baseline (2017) and interim (2018) values extracted from third-party datasets. We assessed compliance with the 20% sugar-reduction target and category-specific energy targets by product category and for pooled desserts. Overall, sugar/portion and energy/portion decreased by 11% and 4%, respectively. Policy targets were achieved in one of five categories (ice-cream: −38% sugar, p < 0.001; −30% energy, p < 0.001). Secondary outcomes were analysed for subgroups with the necessary data. Few chains significantly reduced sugar and/or energy across their dessert range. Energy/portion was positively associated with portion weight and sugar/portion but not with sugar/100 g. More than half of adults' desserts contained excessive sugar and/or saturated fat compared with dietary guidelines. Children's desserts less frequently exceeded guidelines. These results demonstrate that voluntary measures can drive substantial change when technical, commercial, and operational barriers can be overcome. [ABSTRACT FROM AUTHOR]

Fat and sugar-reduced foods and beverages have become increasingly popular for a variety of reasons, mainly relating to health and wellbeing. Depending on the food or beverage, it may be difficult to reduce the fat and/or sugar content and still maintain optimal sensory properties for the specific product. One way of approaching the problem is to gain a better understanding of how a product is affected by a reduction in fat and/or sugar. This paper aims to investigate the sensory interactions between fat and sweetness perception in a chocolate-flavored milk beverage by using a descriptive analysis with a trained sensory panel. The reduction of fat significantly reduced the sweetness intensity of the chocolate milk, while the reduction of sucrose significantly decreased the cream flavor and the fruity and lactic flavor. The perception of acesulfame-K was affected by fat concentration, similarly to sucrose. These results highlight the importance of considering the effects of reducing either sugar and fat on product attributes that are not directly related to the sugar or fat. [ABSTRACT FROM AUTHOR]

Overconsumption of added sugars is associated with higher incidences of obesity, type II diabetes, and cardiovascular disease. Alternative sweeteners have long been relied on as a strategy to reduce consumption of added sugars; however these alternatives differ notably from sucrose in their sensory properties. Recently, consumers have also been looking to reduce consumption of ingredients deemed "artificial," seeking natural alternatives despite poor definitions of these terms on the whole. Wider knowledge of the sensory properties of natural sweeteners would greatly aid in this goal. Descriptive analysis and time–intensity scaling were used to characterize the temporal profile and off‐flavors of allulose, erythritol, rebaudioside (Reb) A, Reb D, Reb M, monk fruit, and thaumatin, as compared to sucrose. Further, each was blended to reduce sucrose by 50% and 75% in binary mixtures. Where significant off‐flavors were frequently reported with sweeteners, when delivered in binary mixtures for partial sugar reduction, these were much mitigated, while also bringing temporal profiles closer to that of sucrose. This suggests that partial sugar reduction may be an effective way of reducing caloric intake while not compromising sensory experience. Practical Application: The use of both descriptive analysis and time–intensity scaling allows for a more complete understanding of the sensory properties of natural alternative sweeteners. Understanding their sensory deficits and ways to improve these sweeteners plays a critical role in creating healthier products that will be accepted by consumers. [ABSTRACT FROM AUTHOR]

Permeates are generated in the dairy industry as byproducts from the production of high‐protein products (e.g., whey or milk protein isolates and concentrates). Traditionally, permeate was disposed of as waste or used in animal feed, but with the recent move toward a "zero waste" economy, these streams are being recognized for their potential use as ingredients, or as raw materials for the production of value‐added products. Permeates can be added directly into foods such as baked goods, meats, and soups, for use as sucrose or sodium replacers, or can be used in the production of prebiotic drinks or sports beverages. In‐direct applications generally utilize the lactose present in permeate for the production of higher value lactose derivatives, such as lactic acid, or prebiotic carbohydrates such as lactulose. However, the impurities present, short shelf life, and difficulty handling these streams can present challenges for manufacturers and hinder the efficiency of downstream processes, especially compared to pure lactose solutions. In addition, the majority of these applications are still in the research stage and the economic feasibility of each application still needs to be investigated. This review will discuss the wide variety of nondairy, food‐based applications of milk and whey permeates, with particular focus on the advantages and disadvantages associated with each application and the suitability of different permeate types (i.e., milk, acid, or sweet whey).

Gymnemic-acids (GA) block lingual sweet taste receptors, thereby reducing pleasantness and intake of sweet food. Objective: To examine whether a 14-day gymnema-based intervention can reduce sweet foods and discretionary sugar intake in free-living adults. Healthy adults (n = 58) were randomly allocated to either the intervention group (INT) or control group (CON). The intervention comprised of consuming 4 mg of Gymnema sylvestre containing 75% gymnema acids, a fibre and vitamin supplement, and an associated healthy-eating guide for 14 days; participants in the CON group followed the same protocol, replacing the GA with a placebo mint. Amount of chocolate bars eaten and sensory testing were conducted before and after the 14-day intervention (post-GA or placebo dosing on days zero and 15, respectively). Food frequency questionnaires were conducted on days zero, 15 and after a 28-day maintenance period to examine any changes in intake of sweet foods. A range of statistical procedures were used to analyse the data including Chi square, t-test and two-way analysis of variance. Post dosing, INT consumed fewer chocolates (2.65 ± 0.21 bars) at day zero than CON (3.15 ± 0.24 bars; p = 0.02); there were no differences between groups at day 15 (INT = 2.77 ± 0.22 bars; CON = 2.78 ± 0.22 bars; p = 0.81). At both visits, a small substantive effect (r < 0.3) was observed in the change in pleasantness and desire ratings, with INT showing a slight increase while CON showed a small decrease over the 14-day period. No differences were found in the intake of 9 food categories between groups at any timepoint. There were no differences in consumption of low sugar healthy foods between visits, or by group. The 14-day behavioural intervention reduced pleasantness and intake of chocolate in a laboratory setting. There was no habituation to the mint over the 14-day period. This study is the first to investigate the effect of longer-term gymnema acid consumption on sweet food consumption outside of a laboratory setting; further research is needed to assess how long the effect of the 14-day intervention persists.

Abstract The excessive consumption of sugars can cause health issues. Different strategies have been developed to reduce sugars in the diets. However, sugars in fruits and commercial products may be difficult to reduce, limiting their usage among certain populations of people. Zymomonas mobilis is a generally recognized as safe (GRAS) probiotic bacterium with the capability to produce levan-type prebiotics, and thrives in high-sugar environments with unique characteristics to be developed for lignocellulosic biofuel and biochemical production. In this study, the sugar reduction capabilities of Z. mobilis ZM4 were examined using two fruits of pear and persimmon and three high-sugar-content commercial products of two pear pastes (PPs) and one Chinese traditional wine (CTW). Our results demonstrated that Z. mobilis ZM4 can utilize sugars in fruits with about 20 g/L ethanol and less than 5 g/L sorbitol produced within 22 h using pears, and about 45 g/L ethanol and 30 g/L sorbitol produced within 34 h using persimmons. When PPs made from pears were used, Z. mobilis can utilize nearly all glucose (ca. 60 g/L) and most fructose (110 g/L) within 100 h with 40 ~ 60 g/L ethanol and more than 20 g/L sorbitol produced resulting in a final sorbitol concentration above 80 g/L. In the high-sugar-content alcoholic Chinese traditional wine, which contains mostly glucose and ethanol, Z. mobilis can reduce nearly all sugars with about 30 g/L ethanol produced, resulting in a final ethanol above 90 g/L. The ethanol yield and percentage yield of Z. mobilis in 50 ~ 60% CTW were 0.44 ~ 0.50 g/g and 86 ~ 97%, respectively, which are close to its theoretical yields—especially in 60% CTW. Although the ethanol yield and percentage yield in PPs were lower than those in CTW, they were similar to those in fruits of pears and persimmons with an ethanol yield around 0.30 ~ 0.37 g/g and ethanol percentage yield around 60 ~ 72%, which could be due to the formation of sorbitol and/or levan in the presence of both glucose and fructose. Our study also compared the fermentation performance of the classical ethanologenic yeast Saccharomyces cerevisiae BY4743 to Z. mobilis, with results suggesting that Z. mobilis ZM4 had better performance than that of yeast S. cerevisiae BY4743 given a higher sugar conversion rate and ethanol yield for sugar reduction. This work thus laid a foundation for utilizing the advantages of Z. mobilis in the food industry to reduce sugar concentrations or potentially produce alcoholic prebiotic beverages. Graphical Abstract

Fiber is a substitute for sugar in chocolates but changes its hygroscopicity and rheological characteristics if their packaging doesn't avoid its moisture gain. The objective of this study was to evaluate the water vapor permeability of different packaging materials (BOPP/metBOPP (biaxial oriented polypropylene /metallized) BOPP/BOPP white and Cellophane) and the effect of the permeability on the rheological properties (by Casson model) of three types of milk chocolate: standard, with the addition of Inulin and Fructooligosaccharides during storage at 20 °C /75% RH. Due to the high hygroscopicity of the fibers, the initial moisture content of the chocolates with fibers was higher than that of standard chocolate. No increase in viscosity were observed at standard and with Inulin chocolates during 270 days at 20 °C/75% RH, regardless of the packaging material used. However, chocolate with FOS packed in cellophane showed changes in their viscosity, with values ranging from 4.63 Pa.s to 7.5 Pa.s after 210 days of storage. In addition, the Inulin chocolate in Cellophane package showed an increase at flow limit from 3 Pa to 6 Pa after 270 days. Therefore, the results indicated that chocolates with fibers should be packed in materials with medium or high barrier to water vapor, such as BOPP/metBOPP and BOPP/BOPP, to avoid rheological changes during storage.

Background: International strategies to reduce chronic diseases have called for a reduction in the amounts of saturated fat (SAFA), trans fat (TFA), salt and sugars in the global food supply. This paper describes the development approach and potential impact of a set of standards for these nutrients to drive food (re)formulation. Methods: To set the standards, WHO nutrient guidelines for daily intake were translated into product group specific standards. The impact of reformulation towards these standards on population nutrient intakes was modelled using the food consumption data of five countries: UK, France, US, Brazil and China. The impact of the TFA standards could not be modelled due to lack of data. Results: (Re)formulation of foods and beverages towards these standards would substantially decrease mean population intakes of energy, sodium, SAFA and sugars, with reductions up to 30%. Conclusions: These science-based standards for nutrients to limit could drive impactful reductions in energy, sodium, SAFA and sugars in food and beverage products, enabling mean population intakes to move closer to WHO nutrient guidelines.

Successful sugar reduction in food products mimics the sensory and functional properties of the full sugar counterpart. The initial step of sugar reduction is to determine how the absence of sugar affects these properties. Descriptive analysis was conducted on four gel types (gelatin, ι-carrageenan, κ-carrageenan, and konjac glucomannan) and a range of sugar concentrations from 0–20% w/v to create a sensory profile of model confectionary gels for comparison to instrumental texture profile analysis data. The sensory descriptive data were analyzed using analysis of variance and principal component analysis. Correlation analysis, cluster analysis, and partial least squares regression (PLS-R) were used to compare and correlate sensory and instrumental data. Regardless of sugar concentration, sensory analysis primarily clustered samples by gelling agent type, such as in the case of konjac glucomannan consistently being characterized as chewy. Cohesion and gumminess were correlated highly with melt-in-mouth and a jiggly texture, while adhesion and fracturability were negatively correlated. In the PLS-R samples biplot, gelatin and iota carrageenan samples were located near these attributes indicating their aptness as descriptors. In conclusion, descriptive analysis provided a more discriminating method for characterizing model confectionary gels. [ABSTRACT FROM AUTHOR]

Consumers are interested in products with reduced sugar, a trend which has been attributed to consumers associating high-sugar foods with obesity, diabetes, heart disease and high blood pressure. The objective of this study was to evaluate consumer perception of sugar reduction in yogurt - both conceptually and for liking of actual products. An online survey (n = 1290) was conducted to evaluate consumer perception of sweeteners available in commercial yogurts. Participants who purchased yogurt at least once in the past 3 mo completed a series of exercises that involved demographics, agreement, Kano, and Maximum Difference (MaxDiff) scaling questions. Subsequently, vanilla 1% milkfat yogurts sweetened with sucrose were formulated to iso-sweet taste intensity with either stevia, allulose, a blend of sucrose and honey or a blend of sucrose, stevia and allulose using magnitude estimate scaling followed by paired comparison tests with consumers (n = 40). A consumer acceptance test (n = 229) was then conducted using the 5 vanilla yogurts. Half of the consumers (n = 115) were primed with the specific yogurt sweetener and the other half were not. Survey and acceptance test data were evaluated by univariate and multivariate analyses. Conceptually, consumers preferred the claim "naturally sweetened" over a reduced sugar claim in yogurt (P < 0.05). Honey was preferred over other sweeteners, followed by agave nectar and cane sugar (P < 0.05). Allulose was the least preferred sweetener option conceptually (P < 0.05). Priming with sweetener type positively impacted consumer acceptance, regardless of sweetener (P < 0.05). When yogurts were tasted, yogurts sweetened with sucrose were the most preferred regardless of priming (P < 0.05). Yogurts sweetened with allulose or a blend of allulose, stevia, and sucrose received higher liking scores than yogurts with stevia (P < 0.05), suggesting that allulose can assist with sugar reduction in yogurt. Consumers are interested in healthy yogurts that are naturally sweetened, but flavor/taste remains the driving force for liking and purchase. The use of a natural non-nutritive sweetener that delivers the sensory experience of sucrose is ultimately more important than familiarity with the actual sweetener., (© 2024, The Authors.

Excessive sugar consumption in young people, who are the major consumers of sugary drinks, combined with limited physical activity, is an important determinant of obesity. Despite their natural appeal, fruit juices have a similar sugar content to that of sugary drinks and once metabolized, they may induce the same biological response. This study aimed to verify whether fermentation processes can make juice consumption healthier and whether reduced-sugar juices have a specific impact on intestinal function. We designed a tailored fermentation of apple-pear juices with lactic acid bacteria and yeasts, which resulted in a reduction of sugar content (27-66%) and caloric intake, and an increase in mannitol content. The impact of newly developed apple-pear juices on gut microbiome composition and functionality was evaluated in vitro using the Simulator of the Human Intestinal Microbial Ecosystem (SHIME). Promising changes were found in the gut microbiota and its metabolic responses and functionality, targeting pathways related to obesity and weight loss (lipopolysaccharide and secondary metabolite biosynthesis, polycyclic aromatic hydrocarbon degradation, and amino sugar and nucleotide sugar metabolism). Additionally, the fermented apple-pear juices positively modulated the intestinal epithelial features. While the simulation of the study simplifies the complex in vivo conditions, it suggests that low-sugar fermented apple-pear juices can elicit targeted responses in the gut ecosystem, contributing to healthier alternatives to traditional fruit juices., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

Sugar is one of the key factors affecting sensory perception and consumers’ acceptance towards healthy foods and beverages. This study aimed to determine the sensory characteristics of three sugar reduced yoghurt drinks [0S0.02T0.6P, 2S0.02T0.3P, 4S0.01T0.3P where S, sugar percentage (0%, 2%, 4%); T, stevia dosage (0.01%, 0.02%); P, pectin dosage (0.3%, 0.6%)] through Check-All-That-Apply (CATA) analysis, evaluated by 151 consumer panellists. Significant differences (p

The Childhood Obesity Plan aimed to reduce sugar and energy in foods through a voluntary sugar-reduction programme. Our primary objective was to determine whether this implementation strategy had been successful, focusing on the out-of-home sector. We used a repeated cross-sectional design to evaluate nutritional changes in desserts served by leading chain restaurants. We extracted nutrition information from online menus in autumn/winter 2020, for comparison with baseline (2017) and interim (2018) values extracted from third-party datasets. We assessed compliance with the 20% sugar-reduction target and category-specific energy targets by product category and for pooled desserts. Overall, sugar/portion and energy/portion decreased by 11% and 4%, respectively. Policy targets were achieved in one of five categories (ice-cream: −38% sugar, p < 0.001; −30% energy, p < 0.001). Secondary outcomes were analysed for subgroups with the necessary data. Few chains significantly reduced sugar and/or energy across their dessert range. Energy/portion was positively associated with portion weight and sugar/portion but not with sugar/100 g. More than half of adults’ desserts contained excessive sugar and/or saturated fat compared with dietary guidelines. Children’s desserts less frequently exceeded guidelines. These results demonstrate that voluntary measures can drive substantial change when technical, commercial, and operational barriers can be overcome.

Fat and sugar-reduced foods and beverages have become increasingly popular for a variety of reasons, mainly relating to health and wellbeing. Depending on the food or beverage, it may be difficult to reduce the fat and/or sugar content and still maintain optimal sensory properties for the specific product. One way of approaching the problem is to gain a better understanding of how a product is affected by a reduction in fat and/or sugar. This paper aims to investigate the sensory interactions between fat and sweetness perception in a chocolate-flavored milk beverage by using a descriptive analysis with a trained sensory panel. The reduction of fat significantly reduced the sweetness intensity of the chocolate milk, while the reduction of sucrose significantly decreased the cream flavor and the fruity and lactic flavor. The perception of acesulfame-K was affected by fat concentration, similarly to sucrose. These results highlight the importance of considering the effects of reducing either sugar and fat on product attributes that are not directly related to the sugar or fat.

This study aimed to investigate consumer expectation of flavored water and potential consumer segments. The results showed flavored water was ranked the fourth most popular drink, after plain water, tea, and coffee, by 901 participants. Consumers highly expected functional flavored water with refreshing (87.4% selection), thirst-quenching (73.7%), and tasty (65.7%) qualities, containing vitamins, minerals, and antioxidants, and providing energy. Expected flavored water sensory qualities included temperature (62.4%), flavor (52.4%), and sweet taste (47.4%); lemon, berry, and lime flavors were most preferred, while bitterness, irritation, astringency, and sourness were least preferred. Pure sugar and honey were rated highest as the sweeteners for flavored water. Likewise, consumers were mostly concerned with taste followed by calories. Single demographic variables (age, reported health condition, drinking frequency, educational level) significantly influenced (p ≤ 0.05) flavored water function, sensory quality, and sugar reduction expectations. Females had higher expectation of flavored water's refreshing and antioxidant functions. Cluster analysis revealed two consumer segments. The younger, low-education, self-reportedly less healthy cluster (mainly college students) expected various functions and flavors such as low temperature, cooling taste, diverse flavors, and sweet taste (and disliked bitterness). The older, educated, employed, self-reportedly healthy cluster had lower expectations of flavored water functions, were less sensitive to bitterness, and preferred no sweetness or little sweetness. These findings provide informative data to establish marketing and sales strategies for promoting flavored water. [ABSTRACT FROM AUTHOR]

Sucrose contributes to the key physical and sensory characteristics of cookies. Due to the negative health effects associated with excess sucrose consumption, the replacement of sucrose in baking applications is of interest. In this study, nine variations of rolled cookies were prepared (n = 3) using a sucrose control (C), Splenda for baking (SB), Equal for baking (EB), Truvia (TR), Sweet'N Low (SNL), and 1:1 (wt%) mixtures of sweeteners and sucrose (S). The cookies were characterized by a width-to-thickness (W/T) ratio, moisture loss, color, hardness, and fracturability. The W/T ratios of TR (5.7) and TR + sucrose (6.6) were similar, the closest to C (7.7), and bigger than (p < 0.05) all other treatments. Color was not affected (p > 0.05) by the sugar type or concentration. C showed the greatest hardness (5268 N), and SNL had the greatest fracturability (8667 N). Overall, regarding physiochemical characteristics, TR + sucrose (1:1 replacement) and SB (100% replacement) were the closest to the control. [ABSTRACT FROM AUTHOR]

To exceed in sugar consumption is one of the main causes of overweight and obesity, especially for children and adolescent. However, sugar reduction, especially in baked goods, is challenging due to its effect not only on sensorial properties but also for other quality parameters.Multiple technological strategies to obtain muffins at low sugar content addressed for children were studied. Specifically, the inhomogeneous spatial distribution of sucrose (1, 3 and 5 layers of food formula at different sugar content), the taste enhancement by vanillin addition (0, 1 and 2%) and the use of different particle size of sugar (200, 400 and 600 μm) were investigated through a Box-Behnken design. Physical attributes were negatively affected by spatial distribution due to the substantial role of sucrose in the expansion of muffins. Indeed, maximum height of homogeneous muffins was of 37.8 ± 3.9 mm, while in inhomogeneous samples reached values of ≈ 30 mm. The low expansion of inhomogeneous muffins was also attested by porosity fraction which notably decreased from 68.2% in 1-layer muffin to 58.4% and 65.6% in 3-layers and 5-layers muffins, respectively. The perception of sweetness was improved for the inhomogeneous muffins and with a mass fraction of added vanillin at 1% confirming its great potential as taste enhancer, especially when using particle size of sugar less than 400 μm. Based on sensorial and physical data, stratified muffins with 3 layers, a mass fraction of added vanillin at 1% and sugar particle size in the range between 200 and 600 μm, showed excellent results. The proposed strategy could be used to design and develop innovative muffins designed for children contributing in the reduction of sugar intake in the daily diet.

There is an urgent need to reduce sugar intake in early childhood. Commercial infant cereals are among the first solid foods introduced to infants at the beginning of the complementary feeding period in most countries. The aim of this study was to examine infants’ overall acceptability of low-sugar complementary cereals. To do so, a between-subjects experimental study with 165 parents and their infants aged 6–24 months was conducted where one group tested a high-sugar refined cereal (21 g/100 g), and the other a low-sugar cereal (

[Display omitted] • Mango aroma could enhance the sweetness perception in the low-sugar model beverage. • The mango aroma could achieve as much as 32.14% sugar reduction without sacrificing overall liking. • The aroma that was congruent with the sweetness is required to induce sweetness enhancement. Excessive intake of sugar has become a public concern. However, it is challenging for food industries to decrease sugar level without sacrificing safety and sensory profile. Odor-induced sweetness enhancement (OISE) is believed to be a novel and promising strategy for sugar reduction. In order to investigate the OISE effect of mango aroma and evaluate its degree of sugar reduction in low-sugar beverages, a mathematical model was constructed through sensory evaluation in this study. The results showed that the maximum liking of low-sugar model beverages was 4.28 % sucrose and 0.57 % mango flavor. The most synergistic of OISE was at the concentration level of 2.24 % sucrose + 0.25 % mango flavor, which was equivalent to 2.96 % pure sucrose solution. With 32.14 % sugar reduction, the mango aroma was suggested to generate the OISE effect. However, the same level of garlic aroma was not able to enhance sweetness perception, suggesting that the congruency of aroma and taste is a prerequisite for the OISE effect to occur. This study demonstrated that the cross-modal interaction of mango aroma on sweetness enhancement in low-sugar model beverages could provide practical guidance for developing sugar-reduced beverages without applying sweeteners.

In the context of increasing global health risks, including obesity, diabetes, and cardiovascular diseases, odor-induced taste enhancement (OITE) has emerged as an important supplement to other sugar reduction strategies, offering a promising way to reduce sugar intake. OITE can be used in conjunction with other sugar reduction methods, and unlike some artificial sweeteners, it does not cause unpleasant aftertastes of bitterness and metallic flavors. However, compared to other approaches, the efficiency of OITE in sugar reduction appears relatively modest. This review aimed to discuss OITE with a focus on the underlying mechanisms, material selection, and innovative techniques. Current explanations of OITE, such as associative learning and natural association , indicate that it can be either acquired or inherent. We also summarized previous strategies for material selection and provided extensive databases of odorants and sweeteners for alternative selections. Finally, we reviewed some technical methodologies used in OITE studies, including experimental and data mining techniques. Broadening the range of potential odorants and sweeteners is essential for improving the sweetening potency of odorants. Caution should be exercised with the use of olfactoscan , as this technique does not actually involve tasting. Emerging technologies, such as machine learning , have significant potential to further increase the efficacy of OITE. As the sweetening efficiency of OITE increases, this strategy will substantially benefit the food industry and human health in the foreseeable future. • Odor-induced taste enhancement (OITE) is a promising strategy for sugar reduction. • Certain incongruent odors can also enhance the perception of sweetness. • Using olfactoscan to screen odorants risks missing important incongruent odors. • OITE can arise from either acquired factors or inherent ones. • Machine learning has significant potential in the perspective of OITE research.

Many American adults consume almost double the daily recommended amount of sugar. With excess consumption of sugar and consequential health problems arising, food manufacturers are investigating methods to reduce sugar while maintaining similar functional and sensory properties. The body of literature was searched for papers regarding sugar reduction, and the main methods of sugar reduction are summarized herein with a specific focus on high sugar products. Reducing sugar in confections is possible; however, the challenge is maintaining the balance between texture and sweetness perception. Texture plays a large role in the sweetness perception of confections, with firmer products often being perceived as less sweet. Depending on the method, 20–40% of sugar can be removed from confections without sacrificing sensory acceptance, often replaced with multiple ingredients. Further investigation is needed on confection models and how the emerging health trends set the foundation for sugar reduction. [ABSTRACT FROM AUTHOR]

The excessive consumption of sugars can cause health issues. Different strategies have been developed to reduce sugars in the diets. However, sugars in fruits and commercial products may be difficult to reduce, limiting their usage among certain populations of people. Zymomonas mobilis is a generally recognized as safe (GRAS) probiotic bacterium with the capability to produce levan-type prebiotics, and thrives in high-sugar environments with unique characteristics to be developed for lignocellulosic biofuel and biochemical production. In this study, the sugar reduction capabilities of Z. mobilis ZM4 were examined using two fruits of pear and persimmon and three high-sugar-content commercial products of two pear pastes (PPs) and one Chinese traditional wine (CTW). Our results demonstrated that Z. mobilis ZM4 can utilize sugars in fruits with about 20 g/L ethanol and less than 5 g/L sorbitol produced within 22 h using pears, and about 45 g/L ethanol and 30 g/L sorbitol produced within 34 h using persimmons. When PPs made from pears were used, Z. mobilis can utilize nearly all glucose (ca. 60 g/L) and most fructose (110 g/L) within 100 h with 40 ~ 60 g/L ethanol and more than 20 g/L sorbitol produced resulting in a final sorbitol concentration above 80 g/L. In the high-sugar-content alcoholic Chinese traditional wine, which contains mostly glucose and ethanol, Z. mobilis can reduce nearly all sugars with about 30 g/L ethanol produced, resulting in a final ethanol above 90 g/L. The ethanol yield and percentage yield of Z. mobilis in 50 ~ 60% CTW were 0.44 ~ 0.50 g/g and 86 ~ 97%, respectively, which are close to its theoretical yields—especially in 60% CTW. Although the ethanol yield and percentage yield in PPs were lower than those in CTW, they were similar to those in fruits of pears and persimmons with an ethanol yield around 0.30 ~ 0.37 g/g and ethanol percentage yield around 60 ~ 72%, which could be due to the formation of sorbitol and/or levan in the presence of both glucose and fructose. Our study also compared the fermentation performance of the classical ethanologenic yeast Saccharomyces cerevisiae BY4743 to Z. mobilis, with results suggesting that Z. mobilis ZM4 had better performance than that of yeast S. cerevisiae BY4743 given a higher sugar conversion rate and ethanol yield for sugar reduction. This work thus laid a foundation for utilizing the advantages of Z. mobilis in the food industry to reduce sugar concentrations or potentially produce alcoholic prebiotic beverages.

Cookies are widely consumed bakery products having high amount of sucrose. In this study, it was aimed to reduce the amount of sucrose used in cookies by using the inhomogeneous distribution of sucrose while maintaining the perceived sweetness. Five different cookie samples were evaluated namely; control, 20% reduced sucrose cookies with Homogeneous distribution (HOM20) and Inhomogeneous distribution (INHOM20), 30% reduced sucrose cookies with Homogeneous distribution (HOM30) and Inhomogeneous distribution (INHOM30). Physical properties (diameter, height, spread ratio, L*, a*, and b*) of INHOM20 cookies were determined to be similar with control sample. Hardness value of control sample (30.43 N) was lower than HOM20 (36.59 N) and INHOM20 (33.09 N), HOM30 (41.32 N) and INHOM30 (38.23 N). Although the sucrose content was reduced 20% by inhomogeneous distribution, cookies had same sweetness and general acceptance with the control sample. The perceived sweetness of INHOM30 cookies was more than HOM30 cookies. The results obtained from this study showed that enhancement of sweetness perception and sucrose reduction could be provided using inhomogeneous sucrose distribution by changing sucrose distribution in cookies without using any sucrose substitute.

Sucrose is an important contributor to the caloric value of a food, in addition to being a relevant nutrient for some diseases, such as diabetes mellitus. This study aimed to reformulate a preparation of pineapple cake, reducing and/or replacing the sugar content. A recipe for pineapple cake was chosen and recipes with modifications were made. Eight formulations were prepared: B1-Standard; B2-Standard with 50% reduction of crystal sugar; B3-Brown sugar; B4-Brown sugar with 50% reduction; B5-Light sugar; B6-Light sugar with 50% reduction; B7-Sweetener and B8-Sweetener with 50% reduction. Subsequently, physical and sensorial analyses of the preparations were made. A higher specific density of the raw mass was observed in B5 and a lower density in B8. Regarding the specific volume of the cakes, the highest averages were found in B1, B7 and B8. Formulations B1, B2 and B6 obtained greater acceptance in terms of attributes, sweetness, consistency, appearance and overall impression. With 50% reduction or replacement of sugar by the sweetener, as seen in B2 and B6, respectively, there was no statistically significant change in the physical characteristics or a rejection factor. Therefore, it is possible to develop pineapple cake formulations with sugar reduction and/or substitution without losing their sensorial and physical volume properties, in order to guarantee their acceptability.

Background: Short and animated story-based (SAS) videos can be an effective strategy for promoting health messages. However, health promotion strategies often motivate the rejection of health messages, a phenomenon known as reactance. In this study, we examine whether the child narrator of a SAS video (perceived as nonthreatening, with low social authority) minimizes reactance to a health message about the consumption of added sugars.Objective: This study aims to determine whether our SAS intervention video attenuates reactance to the sugar message when compared with a content placebo video (a health message about sunscreen) and a placebo video (a nonhealth message about earthquakes) and determine if the child narrator is more effective at reducing reactance to the sugar message when compared with the mother narrator (equivalent social authority to target audience) or family physician narrator (high social authority) of the same SAS video.Methods: This is a web-based randomized controlled trial comparing an intervention video about sugar reduction narrated by a child, the child's mother, or the family physician with a content placebo video about sunscreen use and a placebo video about earthquakes. The primary end points are differences in the antecedents to reactance (proneness to reactance, threat level of the message), its components (anger and negative cognition), and outcomes (source appraisal and attitude). We performed analysis of variance on data collected (N=4013) from participants aged 18 to 59 years who speak English and reside in the United Kingdom.Results: Between December 9 and December 11, 2020, we recruited 38.62% (1550/4013) men, 60.85% (2442/4013) women, and 0.52% (21/4013) others for our study. We found a strong causal relationship between the persuasiveness of the content promoted by the videos and the components of reactance. Compared with the placebo (mean 1.56, SD 0.63) and content placebo (mean 1.76, SD 0.69) videos, the intervention videos (mean 1.99, SD 0.83) aroused higher levels of reactance to the message content (P<.001). We found no evidence that the child narrator (mean 1.99, SD 0.87) attenuated reactance to the sugar reduction message when compared with the physician (mean 1.95, SD 0.79; P=.77) and mother (mean 2.03, SD 0.83; P=.93). In addition, the physician was perceived as more qualified, reliable, and having more expertise than the child (P<.001) and mother (P<.001) narrators.Conclusions: Although children may be perceived as nonthreatening messengers, we found no evidence that a child narrator attenuated reactance to a SAS video about sugar consumption when compared with a physician. Furthermore, our intervention videos, with well-intended goals toward audience health awareness, aroused higher levels of reactance when compared with the placebo videos. Our results highlight the challenges in developing effective interventions to promote persuasive health messages.Trial Registration: German Clinical Trials Registry DRKS00022340; https://tinyurl.com/mr8dfena.International Registered Report Identifier (irrid): RR2-10.2196/25343.

Abstract Background The consumption of free sugars in the UK is more than double the guideline intake for adults and close to triple for children, with soft drinks representing a significant proportion. The aim of this study was to assess how individual soft drink companies and consumers have responded to calls to reduce sugar consumption, including the soft drink industry levy (SDIL), between 2015 and 2018. Methods This was an annual cross-sectional study using nutrient composition data of 7377 products collected online, paired with volume sales data for 195 brands offered by 57 companies. The main outcome measures were sales volume, sugar content and volume of sugars sold by company and category, expressed in total and per capita per day terms. Results Between 2015 and 2018, the volume of sugars sold per capita per day from soft drinks declined by 30%, equivalent to a reduction of 4.6 g per capita per day. The sales-weighted mean sugar content of soft drinks fell from 4.4 g/100 ml in 2015 to 2.9 g/100 ml in 2018. The total volume sales of soft drinks that are subject to the SDIL (i.e. contain more than 5 g/100 ml of sugar) fell by 50%, while volume sales of low- and zero-sugar (

Gymnemic-acids (GA) block lingual sweet taste receptors, thereby reducing pleasantness and intake of sweet food. Objective: To examine whether a 14-day gymnema-based intervention can reduce sweet foods and discretionary sugar intake in free-living adults. Healthy adults (n = 58) were randomly allocated to either the intervention group (INT) or control group (CON). The intervention comprised of consuming 4 mg of Gymnema sylvestre containing 75% gymnema acids, a fibre and vitamin supplement, and an associated healthy-eating guide for 14 days; participants in the CON group followed the same protocol, replacing the GA with a placebo mint. Amount of chocolate bars eaten and sensory testing were conducted before and after the 14-day intervention (post-GA or placebo dosing on days zero and 15, respectively). Food frequency questionnaires were conducted on days zero, 15 and after a 28-day maintenance period to examine any changes in intake of sweet foods. A range of statistical procedures were used to analyse the data including Chi square, t-test and two-way analysis of variance. Post dosing, INT consumed fewer chocolates (2.65 ± 0.21 bars) at day zero than CON (3.15 ± 0.24 bars; p = 0.02); there were no differences between groups at day 15 (INT = 2.77 ± 0.22 bars; CON = 2.78 ± 0.22 bars; p = 0.81). At both visits, a small substantive effect (r < 0.3) was observed in the change in pleasantness and desire ratings, with INT showing a slight increase while CON showed a small decrease over the 14-day period. No differences were found in the intake of 9 food categories between groups at any timepoint. There were no differences in consumption of low sugar healthy foods between visits, or by group. The 14-day behavioural intervention reduced pleasantness and intake of chocolate in a laboratory setting. There was no habituation to the mint over the 14-day period. This study is the first to investigate the effect of longer-term gymnema acid consumption on sweet food consumption outside of a laboratory setting; further research is needed to assess how long the effect of the 14-day intervention persists.
