In April 2018, South Africa became the first African country to implement a Health Promotion Levy (HPL) on sugar-sweetened beverages (SSBs). This study assessed sugar tax awareness among rural-based university students and involved 342 participants, with an additional 10% to account for attrition. However, only 257 students, randomly selected from six university residences at the University of Venda, reported consuming SSBs. Systematic sampling determined the room selection, and the data was collected through an interviewer-administered questionnaire (8–28 October 2022). A knowledge questionnaire assessed the students’ understanding of the sugar tax. The results showed that 65.8% purchased SSBs five to six times a week, while 41.2% spent over R200 monthly on these beverages. The results showed that students had limited awareness and little perception of the sugar tax, reflecting a broader knowledge gap. Their negative behaviors toward sugar-sweetened beverages indicated that changing their consumption patterns would be challenging. Raising public awareness through taxation is widely recognized as an effective obesity prevention strategy, but misinformation, negative perceptions, and pessimistic attitudes may contribute to continued high consumption.

Consumption of sugar-sweetened beverages (SSBs) contributes to the risk of developing overweight and obesity in children and adults. Thus, reducing free sugar is a globally recognized public health priority. The implementation of a sugar tax is one way of achieving this goal. This study aimed to investigate the relationship between familiarity with the sugar tax and its importance in reducing obesity, the perceived health consequences of SSBs, situations and reasons for consumption, and the frequency of SSB consumption. A cross-sectional study was conducted in May 2022 among 216 Polish adults (age 18–45). Hierarchical cluster analysis was used to identify three homogeneous clusters with regard to the perceived health consequences of consuming SSBs. A logistic regression model was used to verify the relationship between the frequency of SSB consumption (dependent variable) and other variables. Respondents with higher familiarity with the sugar tax (OR: 0.594; 95% CI: 0.42–0.85) and those in the “Unaware of disease” (OR: 0.437; 95% CI: 0.18–0.94) and “Disease-conscious” (OR: 0.484; 95% CI: 0.24–0.97) clusters were less likely to consume SSBs at least once per week than those in the “Moderately disease-conscious” cluster. Both the place of SSB consumption (i.e., restaurant—OR: 1.847; 95% CI: 1.14–3.64, work or university—OR: 3.217; 95% CI: 1.51–6.88, family home—OR: 2.877; 95% CI: 1.50–5.53) as well as a preference for their taste (OR: 4.54; 95% CI: 1.66–12.45) increased the chance of consuming SSBs at least once a week. In conclusion, it is necessary to continue educating the public about the health consequences of SSB consumption. The use of legislative measures (i.e., sugar tax) also contributes to reducing SSB consumption and can thus counteract the increasing obesity rate. Full article

In 2021, the tax on sweetened beverages was introduced in Poland. It is worth knowing how consumers, especially young people, perceive the tax and whether there are any changes in the consumption of such drinks. This cross-sectional study was conducted in 2022 and analyzed a convenience sample of young people’s attitudes towards the effectiveness of the tax as well as beverage consumption in the second year of the tax’s implementation. This study was conducted using a questionnaire method among 334 young people (167 school students and 167 university students). The vast majority of the study participants (84%) had heard about the introduction of the tax (there was no statistically significant difference between the school students’ and the university students’ knowledge). Of these, 90% knew that beverages with added sugar are taxed, but only 43% were conscious that beverages with sweeteners are also subject to the tax. Forty percent of those surveyed believed that the introduction of the tax could reduce beverage consumption, while 35% denied this possibility. The view that the tax would have a beneficial effect on reducing drink consumption was statistically significantly more frequently expressed by school students compared to university students (55% vs. 25%; p < 0.05). Of those who were aware of the tax, 31% declared they drank fewer beverages following its introduction, while 58% reported that they had not changed the amount they drank. About 33% of the respondents said they drank sweetened beverages several times a week. According to the study, as a result of the tax, almost one-third of surveyed young Poles reported drinking less beverages than before the tax. Full article

Bioenergy with carbon capture and storage (BECCS) or utilization (BECCU) allows net zero or negative carbon emissions and can be a breakthrough technology for climate change mitigation. This work consists of an energetic, exergetic, and economic analysis of an integrated process based on chemical looping combustion of solar-torrefied agro-industrial residues, followed by methanation of the concentrated CO₂ stream with green H₂. Four agro-industrial residues and four Italian site locations are considered. Depending on the considered biomass, the integrated plant processes about 18–93 kg h⁻¹ of raw biomass and produces 55–70 t y⁻¹ of synthetic methane. Global exergetic efficiencies ranged within 45–60% and 67–77% when neglecting and considering, respectively, the valorization of torgas. Sugar beet pulp and grape marc required a non-negligible input exergy flow for the torrefaction, due to the high moisture content of the raw biomasses. However, for these biomasses, the water released during drying/torrefaction and CO₂ methanation could be recycled to the electrolyzer to eliminate external water consumption, thus allowing for a more sustainable use of water resources. For olive stones and hemp hurd, this water recycling brings, instead, a reduction of approximately 65% in water needs. A round-trip electric efficiency of 28% was estimated assuming an electric conversion efficiency of 40%. According to the economic analysis, the total plant costs ranged within 3–5 M€ depending on the biomass and site location considered. The levelized cost of methane (LCOM) ranged within 4.3–8.9 € kg_CH4⁻¹ but, if implementing strategies to avoid the use of a large temporary H₂ storage vessel, can be decreased to 2.6–5.3 € kg_CH4⁻¹. Lower values are obtained when considering hemp hurd and grape marc as raw biomasses, and when locating the PV field in the south of Italy. Even in the best scenario, values of LCOM are out of the market if compared to current natural gas prices, but they might become competitive with the introduction of a carbon tax or through government incentives for the purchase of the PV field and/or electrolyzer.

This study investigates the implementation of national policies and strategies to control unhealthy diets, which are pivotal in the global surge of non-communicable diseases. Leveraging data from the World Health Organization’s Non-Communicable Diseases Progress Monitors and Country Capacity Surveys, we calculated aggregate implementation scores for 13 diet-related policies across 194 countries from 2017 to 2021. We used descriptive statistics and linear regression to investigate the implementation trends and associations between key national-level factors and implementation scores. The mean score in 2021 was 52% (SD = 24), with no statistical differences in the 5-year period. Stark disparities in implementation efficacy were noted, ranging from comprehensive adoption in some nations to minimal application in others. Our analysis also highlights a shifting focus in policy adoption: notably, an increased commitment to taxing sugar-sweetened beverages juxtaposed with a decline in dietary awareness initiatives. Significant predictors of policy implementation include the Human Development Index, the cost of a healthy diet, and health service coverage. These findings suggest a complex interdependence of socioeconomic factors influencing policy implementation. Our research underscores the need for multifaceted, globally collaborative strategies to effectively combat diet-related diseases, emphasizing the importance of comprehensive policy frameworks in public health interventions.

The negative consequences of commercial determinants of health (CDoH) have become a major challenge for public health systems, especially in terms of non-communicable diseases (NCDs). CDoH are defined as profit-driven factors that influence health. In this study, we assessed the awareness of CDoH and the attitudes toward potential restrictions on advertising, as well as fiscal interventions targeting food products with harmful effects on health in Polish society. Our analysis is based on data from a computer-based web interviewing (CAWI) survey performed in May 2022 among 2008 adult internet users from Poland. Multivariable logistic regression models were developed for variables derived from three items exploring the respondents’ understanding of the relationship between CDoH and NCDs, as well as three items asking about their acceptance of a prohibition of advertising unhealthy products during sports events, a general ban on unhealthy food advertising, and their attitudes toward sugar-sweetened beverages (SSBs). Food (FL) and e-health literacy (eHL) levels were consistently positive predictors of both awareness of CDoH and acceptance of the proposed actions. Both higher FL and eHL were significantly associated with the opinion that advertising unhealthy food is associated with the prevalence of NCDs (OR, 95% CI: 1.03, 1.02–1.05, and 1.04, 1.02–1.06, respectively). Health literacy was less frequently a significant predictor of the dependent variables. Among sociodemographic factors, a respondent’s level of education and age showed a significant relationship with their awareness and acceptance of countermeasures against CDoH. Respondents with a university master’s level of education were more likely to agree with the statement on the relationship between big industry profits and harm to society’s health (OR, 95% CI: 1.96, 1.42–2.69) and to support a ban on advertising unhealthy food similar to that for tobacco products (OR, 95% CI: 1.66, 1.21–2.27). Respondents suffering from chronic diseases were also consistently more likely to show a greater understanding of the harmful impact of CDoH and support proposed restrictions. For example, they were more likely to agree with restrictions on advertising harmful products during sports events (OR, 95% CI: 1.23, 1.02–1.50) and the introduction of a sugar tax (OR, 95% CI: 1.26, 1.03–1.54). Our study revealed that more than 50% of the Polish population is conscious of the problem of the harmful effects of big industries producing and selling processed food, sugar-sweetened beverages, and alcoholic beverages. Interestingly, slightly more than half of the respondents supported the introduction of restrictions on advertising such products. Still, only approximately 30% of them accepted a sugar tax to counter the obesity epidemic. The results of our study indicate that Polish society is open to the introduction of regulations aimed at limiting the impact of commercial determinants of health. To our knowledge, this is one of the first studies to assess the awareness of CDoH and the acceptance of restrictions to limit their impact. Full article

University students should be informed about sugar-sweetened beverages (SSBs). Given the high consumption level of SSBs in Saudi Arabia, this study aims to examine the knowledge, attitudes, and practices related to SSBs and taxes. This cross-sectional study was conducted on 380 students at King Abdulaziz University in Jeddah between September 2022 and March 2023. The data were collected using an online self-administered questionnaire. The results reveal that 93% of the students had high knowledge scores, 99% have positive attitudes, and 37% present good practices toward SSBs. Moreover, 73% of students have high knowledge scores, 83% have positive attitudes, and 32% present good practices regarding SSB taxes. Each of these variables, college education, smoking, family income, body mass index, activities, and sports, showed statistically significant differences between gender with regard to the scores for knowledge, attitudes, and practice towards SSBs and their taxes. Thus, a high percentage of university students present sufficient knowledge of and good attitudes towards SSBs and taxation, unlike the practical results. Policymakers should develop strategic approaches and education campaigns to improve practices towards SSBs. Full article

An epidemic of obesity emerged in the USA in 1976–1980. The epidemic then spread to many other Westernized nations. Many interventions have been carried out with the goal of lowering the prevalence of obesity. These have mostly taken the form of various types of health promotion (i.e., providing people with education, advice, and encouragement). These actions have achieved, at most, only limited success. A strategy with a better chance of success starts with the recognition that the fundamental cause of obesity is that we live in an obesogenic environment. It is therefore necessary to change the environment so that it fosters a generally healthy lifestyle, thereby leading to enhanced health for the population, including improved weight control. A major goal is to increase the intake of healthy foods (especially fruit, vegetables, and whole grains), while decreasing intake of unhealthy foods (especially ultra-processed foods such as sugar). This will require major changes of many government policies. Some of the required policies are as follows. Schools should implement policies that create a healthy environment for children. For example, they should adopt a policy that only foods of high nutritional quality are sold in vending machines or given to students within school meals. Policies need to go well beyond the school setting; a broad strategy is needed that creates a healthy environment for children. Another important policy is the manipulation of food prices in order to shift the diet toward healthy foods. This requires using subsidies to lower the price of healthy foods, while adding a tax to less healthy foods to increase the price. This policy has been implemented in many cities and countries in the form of a tax on sugar-sweetened beverages (SSBs). The advertising of unhealthy foods (including fast-food restaurants) should be banned, especially where children and adolescents are the major target. Such a ban could be extended to a complete ban on all advertising for unhealthy foods, including that directed at adults. The proposed policy measures are likely to be strongly opposed by food corporations. Full article

Intestinal microbiota has been involved in several processes that benefit the host, such as digestion, nutrient metabolism, resistance to pathogens colonization and immune function. In this study, we investigated the diversity, composition and functional prediction of microbiota of reared Seriolella violacea (palm ruff) in the same cohort sampled at different times (7-, 8- and 9-month-old). Microbial community structure analyses, using 16S rRNA amplicon sequencing, revealed that the intestinal microbiota was dominated by the phyla Firmicutes, Proteobacteria, Fusobacteria and Tenericutes. At the genus level, Candidatus Arthromitus was the most abundant in all sampled timepoints, representing in average 78% of the bacterial community (ranging from 18 to 98%), corresponding to segmented filamentous bacteria, which are interesting because they have been associated with the maturation of immune responses in the gut and protecting the host from bacterial infections. The comparisons of the intestinal microbiota among the three groups showed differences in abundance of bacterial taxa and also in alpha diversity indexes (Shannon and Simpson), as well as beta diversity metrics (weighted and unweighted UniFrac). Potential functions of the intestinal microbiota of palm ruff were retrieved using Philipin and Tax4fun and these analyses revealed high levels of genes for sugar metabolism. To our knowledge, this study represents the first description of the intestinal microbiota of S. violacea. Full article

The adoption of fiscal policies based on the specific taxation of sugar-sweetened beverages (SSBs) has been recommended by international health agencies, as they are measures that potentially reduce consumption. This study is an ex ante risk comparison that estimates the impact of three tax scenarios (20, 25, and 30%) with a 100% pass-on rate to SSBs on the prevalence of high weight and obesity in the Brazilian population. Data on the consumption habits, weight, and height of 46,164 adults aged 20 years or over from Brazilian recent national surveys were used. The shift in consumption after taxation was estimated based on the price elasticity of the demand. The percentage changes in overweight for 20, 25, and 30% taxation were 1.84% (95%CI: 1.82; 1.86), 1.89% (95%CI: 1.87; 1.90), and 2.25% (95%CI: 2.24; 2.27), respectively. The change in the prevalence of obesity was 1.93% (95%CI: 1.87; 2.00), 2.90% (95%CI: 2.80; 3.02), and 4.16% (95%CI: 4.01; 4.32), respectively. Taxes on SSBs may have a more favorable result among the heaviest consumers, who are young adults (20–29 years), especially men, thereby promoting a greater reduction in the prevalence of high weight and obesity.

The aim of this study was to estimate changes in the composition of carbonated and non-carbonated sugar-sweetened beverages before and after the introduction of the beverage tax in Poland. Based on the labels of 198 drinks, the composition and nutritional values of the drinks were compared. The nonparametric Mann–Whitney test was applied to compare the differences in the sugar and juice content as well as energy value. After the introduction of the tax, the median sugar content in the carbonated beverages decreased from 8.6 g to 6.9 g/100 mL (p = 0.004), while in the non-carbonated beverages, it decreased from 5.5 g to 4.8 g/100 mL (p < 0.001). In the entire beverage group, there was a significant drop in the proportion of beverages that contained >5 g of sugars/100 mL (44.4% in 2021 vs. 70.2% in 2020). The median juice content in the carbonated beverages increased from 1.0% to 3.3% (p = 0.121), but totalled 20.0% for both periods in the non-carbonated beverages. The percentage of beverages with a tax-exempt composition (juice content ≥ 20% and sugar content ≤ 5 g/100 mL) almost tripled. After the introduction of the tax, beneficial changes in the compositions of 62% of the analysed beverages were observed in terms of their sugar and/or juice content. Full article

Reducing high-calorie food and beverages consumption is a multi-dimensional challenge spanning agriculture to food marketing. Adverse health effects resulting from sugar-sweetened beverages such as obesity, diabetes, cardiovascular disease or dental carries have been described on numerous occasions. Poland is one of the countries that have introduced the sugar tax. The study aims to understand the degree of consumers’ awareness of the upcoming changes and their opinions and assessments of the efficiency of various activities. The study was based on Computer-Assisted Web Interview (CAWI). The sample comprised 500 adult consumers. Most of the respondents (69.6%) are aware that a new charge for sweetened beverages is going to be introduced, and for 78.9% of the respondents, it is important to take action aimed at reducing the consumption of sweetened beverages by consumers. Well-educated respondents as well as women perceive a greater degree of need to take specific action within the area of health policy (p-value 0.010 and 0.000 respectively). The sugar tax is considered an effective tool for limiting the purchase of sweetened products. Other types of activities within the framework of preventative healthcare that aim to reduce the consumption of sugar by society should also be developed. Full article

High sugar intake contributes to diet-related excess weight and obesity and is a key determinant for noncommunicable diseases (NCDs) in low- and middle-income countries (LMICs). The World Health Organization (WHO) gives specific advice on limiting sugar intake in adults and children. Yet, to what extent have policy ideas on sugar intake reduction originating at the global level found expression at lower levels of policymaking? A systematic policy document analysis identified policies issued at the African regional, South African national and Western Cape provincial levels between 2000 and 2020 using search terms related to sugar, sugar-sweetened beverages (SSBs), and NCDs. Forty-eight policy documents were included in the review, most were global and national policies and thus the focus of analysis. A policy transfer conceptual framework was applied. Global recommendations for effectively tackling unhealthy diets and NCDs advise implementing a mix of cost-effective policy options that employ a multisectoral approach. South African country-level policy action has followed the explicit global guidance, and ideas on reducing sugar intake have found expression in sectors outside of health, to a limited extent. As proposed in this paper, with the adoption of the SSB health tax and other policy measures, South Africa’s experience offers several learnings for other LMICs. Full article

In-depth analysis of the decoupling state between cultivated land carbon emissions and cultivated land use factors can provide a basis for coordinating the relationship between food security and ecological environment. On the base of systematically calculating the carbon source of cultivated land, this paper calculated the carbon emission of cultivated land in China’s main agricultural production areas from 2000 to 2020, and explored its temporal and spatial pattern and evolution process. Then, using the LMDI decomposition method and the improved kaya identity, the factors affecting the carbon emissions of cultivated land are divided into five effects: structure, economy, technology, society and population, and then the Tapio decoupling theory is used to analyze the relationship between carbon emissions and these five effects. At the same time, to explore the further relationship between carbon emissions and cultivated land structure, we also studied the decoupling state between carbon emissions and the cultivated land area of 6 main crops. The results showed: during the study period, carbon emissions experienced three stages: fluctuating growth, accelerated growth and slow decline. In the most recent stage, structural, economic and population effects still have some impact on the carbon emissions of cultivated land, changes in cultivated land area where cotton, sugar and tobacco are planted will still affect its carbon emissions. To intervene, policy measures such as promoting the use of clean energy, increasing agricultural imports, and increasing carbon taxes for some industries can be considered. Full article

(1) Background: Taxes on sugar-sweetened beverages are an effective public health intervention, but can be difficult to implement in the absence of public support. This is the first study to analyze the Spanish population’s support for a tax on sugar-sweetened beverages. (2) Methods: We conducted a cross-sectional study of a representative sample of the Spanish adult population (n = 1002), using a computer-aided telephone interview with a questionnaire on nutritional policies. The support for the tax was calculated by the percentage of those who agreed plus those who strongly agreed with the measure. The sociodemographic determinants of support for the tax were analyzed using chi-squared test (χ²) and Poisson multiple regression models with robust variance. (3) Results: Of the participants, 66.9% supported a tax on sugar-sweetened beverages. Support for the tax was 9.2% higher (70% vs. 64.1%) when responders were first asked about support for tax relief and subsidies for healthy foods (p = 0.049). Support for the tax was 16% and 35% lower among persons reporting center and right-wing political sympathies (p < 0.01), and 16% lower among regular consumers of sugar-sweetened beverages (p = 0.01). (4) Conclusions: A clear majority of the Spanish population is in favor of imposing a tax on sugar-sweetened beverages. Awareness-raising campaigns and a policy of combining the measure with subsidies or tax cuts on healthy foods could increase the level of support among those currently against the intervention.
