Coal price, economic growth and electricity consumption in China under the background of energy transition

With the increasing share of renewable energy generation in China's electricity consumption and the dramatic fluctuation of coal prices in recent years, the discussion of the relationship between coal prices, economic growth and electricity consumption in China becomes more relevant. This paper collects monthly data from 2016 to 2023, uses industrial value added to represent economic growth, and explore the relationship between the three through a time-varying parameter vector autoregressive (TVP-VAR) model, which shows that: (1) The mutual impact effects among coal prices, economic growth, and electricity consumption vary across short-, medium- and long-term. This finding underscores the importance of considering different time horizons when evaluating the interactive effects of these variables. (2) Compared to 2017 and 2022, the lagged impact effects among the three have undergone certain changes, indicating that the understanding of their relationships should be contextualized within specific developmental phases. (3) The relationship between coal prices, economic growth, and different categories of electricity consumption exhibits heterogeneous characteristics, suggesting that recognition of these relationships should be based on specific types of power generation. This research enhances the understanding of the dynamic relationship between coal prices and the macroeconomy in China at the current stage.

Protective Effect of Extra Virgin Olive Oil on Cancers, Gastrointestinal Cancers, and All-Cause Mortality: A Competing Risk Analysis in a Southern Italian Cohort

Background/Objectives: This study investigates the association between extra virgin olive oil (EVOO) consumption and mortality risk in a cohort of Italian adults adhering to the Mediterranean diet. Methods: In a 17-year follow-up study involving participants from Castellana Grotte, Italy (2005–2023), we analyzed dietary intake and mortality data. Participants were categorized into three EVOO consumption groups: <30 g/day, 30–50 g/day, and >50 g/day. Mortality Hazard Ratios (HR) and Subdistribution Hazard Ratios (SHR) were calculated to assess the relationship between EVOO intake and all-cause and cancer mortality. Results: Higher EVOO consumption was associated with significantly reduced cancer and all-cause mortality. Specifically, the daily intake of 30–50 g of EVOO was linked to a 24% lower risk of all-cause mortality (HR 0.77; 95% CI 0.63–0.93), while the consumption of more than 50 g/day was associated with a 20% reduction (HR 0.80; 95% CI 0.65–0.98). The most pronounced benefit was observed for gastrointestinal cancers, with a 60% lower mortality risk for those consuming over 50 g/day (SHR 0.39; 95% CI 0.21–0.73). A 50% reduction in mortality risk from other cancers was also noted for the highest consumption category (SHR 0.50; 95% CI 0.31–0.81). Conclusions: The findings support the beneficial role of EVOO in reducing cancer mortality, particularly with higher consumption levels. The results underscore EVOO’s potential as a dietary intervention for cancer prevention, aligning with the Mediterranean diet’s overall health benefits. Further research is needed to confirm these findings and explore the underlying mechanisms.

Association between bubble tea consumption and mental health among adults in mainland China: A national cross-sectional analysis of cohort study

BackgroundBubble tea has emerged as an essential beverage in the daily lives of many individuals, which is particularly pronounced among nurses. However, few studies have investigated the potential effects of bubble tea consumption on mental health among nurses. In this study, we aimed to investigate the association between bubble tea consumption and mental health among nurses. MethodsA cross-sectional analysis using baseline data from the Nurses' Mental Health Study (NMHS), a national cohort study. Odds ratios (ORs) were employed to evaluate the relationship between bubble tea consumption and mental health. ResultsA total of 132,910 participants were enumerated nationwide in our survey. 8666 (6.52 %) were male and 124,244 (93.48 %) were female. The median age of participants was 34 years. After adjusting for potential confounders, the odds ratios (ORs) for depressive symptoms, anxiety symptoms, psychiatric diagnosis, fatigue, burnout, loneliness, and well-being trend changed across categories of bubble tea consumption. Low frequency of bubble tea consumption was associated with a lower risk of suicidal ideation, while high frequency of consumption was related to an increased suicidal risk. The relation between bubble tea and mental health varies with gender and age. ConclusionsThis large-sample cross-sectional study found that consumption of bubble tea was significantly associated with increased anxiety, depression, psychiatric diagnosis, fatigue, job burnout and loneliness, and decreased well-being among nurses. Moreover, research indicates that limited consumption of bubble tea may be correlated with a reduction in suicidal ideation, whereas excessive consumption may be linked to an increase in such ideation.

Life Cycle Assessment of Consumption Patterns – Understanding the links between changing social practices and environmental impacts

As we are still not on track to achieve environmental sustainability through technological change, we need to further stress the importance of understanding routinized types of behaviour by private households and the environmental assessment of corresponding consumption of resources. Social practice theories allow us to understand the constitution of human activity and its embeddedness in society. In transformation research, the relevance of social practice theories has been recognized. However, there is still a lack of understanding regarding the conditions under which practices change substantially and what kinds of tools and governance approaches are suitable to foster change in social practices. We therefore propose a novel way to address the transformation of consumption patterns of private households by a) connecting social practice theories to life cycle assessment for a quantitative environmental evaluation of transformation processes and b) using narrative approaches to understand the links between several social practices and conditions for change. An illustrative study of a bottom-up neighbourhood initiative shows how specific meanings and values (expressed, for example, through meanings of “enough”) affect several social practices from different consumption categories (nutrition, daily mobility, travelling). Environmental assessments further show that changing social practices across consumption categories can substantially decrease environmental pressures from private household consumption, especially in the field of nutrition. The understanding of how various social practices are connected in a nexus through narratives embodying deeper meanings point to novel ways of fostering change and the relevance of social practices related to urban or neighbourhood initiatives as an entry point to a more sustainable way of living.

Association between nut consumption and mortality risk: a 20-year cohort study in Korea with a stratified analysis by health-related variables.

Although nuts are a well-known healthy food group, the relationship between nut consumption and mortality remains unclear, particularly among Asians. This prospective cohort study examined the association between nut consumption and the risk of all-cause, cardiovascular disease (CVD), and cancer mortality in Korean adults. Data from two cohorts (the Ansan-Ansung and Health-Examinees) from the Korean Genome and Epidemiology Study were used. A total of 114,140 individuals aged 40-79 years were included in the data analyses. Nut consumption was assessed using a validated semi-quantitative food frequency questionnaire and categorized into four groups: non-consumers, less than 1 serving/week, 1-2 servings/week, and 2 or more servings/week (one serving was 15g of nuts). Mortality outcomes were determined based on the 2001-2021 death records from Statistics Korea. Cox proportional hazard regression analysis was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality across nut consumption categories. A stratified subgroup analysis by health-related variables was also performed. During a mean follow-up of 12.3 years, 4,559 deaths were recorded. After adjusting for covariates, the HR for all-cause mortality was 0.877 (95% CI = 0.772-0.996, p for trend = 0.006) in individuals with a nut consumption of 2 or more servings/week compared with that in non-consumers. Multivariable HRs for CVD mortality were 0.800 (95% CI = 0.681-0.939) in individuals consuming less than 1 serving/week, 0.656 (95% CI = 0.469-0.918) in those consuming 1-2 servings/week, and 1.009 (95% CI = 0.756-1.347) in those consuming 2 or more servings/week compared with that in non-consumers (p for trend = 0.080). No association was observed between nut consumption and cancer mortality. Stratified analysis identified significant interactions in the association between nut consumption and all-cause mortality by age, body mass index, and physical activity. Nut consumption was linearly associated with the reduced risk of all-cause mortality and showed a non-linear dose-response relationship with CVD mortality in Koreans, but had no association with cancer mortality. The effects of nut consumption, which have been inadequately investigated in this population, varied across different subgroups. These findings suggest that incorporating nuts into the diet should be encouraged for long-term health of Korean adults.

ALTERNATIVE NATURAL SWEETENERS AS SUGAR SUBSTITUTES USED IN MAKING ICE CREAM

Ice cream is a frozen dessert highly appreciated by all categories of consumers. Lately, consumers' attention is focused on healthy products, with as few ingredients as possible or with natural ingredients. By definition, ice cream is a sweet product. As a rule, sugar is used to obtain ice cream for its characteristics (sweet taste, creaminess, texture, melting time), but the new requirements require the addition or substitution of sugar with other sweeteners. Consumers still prefer the sweet taste of artificial sweeteners, but they are cultivating their taste and increasingly choosing natural nutritious or non-nutritive sweeteners as consumer awareness of healthy foods has increased. This manuscript was based on the study of the literature regarding the use of natural sweeteners in ice cream formulations.

Toward sustainable energy transition: understanding electricity-use behavior among low-income urban households in Kumasi

ABSTRACT The residential sector is a critical contributor to global energy consumption. In Ghana, it accounts for 47% of the total electricity consumed. However, inadequate knowledge of categories of residential consumers, their profiles, and the implications on their consumption patterns could impede the development of targeted and sustainable interventions. This study examined the behavioral patterns among low-income urban households in Kumasi, using their socio-demographic and housing characteristics, and self-reported values. This is coherent to the current discourse on Ghana’s transition to zero carbon by 2070 given that Kumasi is the fastest-growing city in the country. Using quantitative methods within a transdisciplinary research design, a survey of 285 households was conducted. The findings yielded varied outcomes. Households reported good electricity use behavior (e.g. covering liquids in the refrigerator) and poor behaviors (e.g. not adjusting the power setting of refrigerators to weather conditions). Logistic regression operations showed associations between energy use behavior, the type of housing units and the type of electricity meters. A significant proportion of respondents exhibited pro-environmental behaviors across all nine value domains. The study concludes that low-income households engage in energy-saving practices. We suggest that policy mediation could enhance the effectiveness of behavioral interventions toward electricity use efficiency.

Research on carbon emission reduction based on responsibility of four participants with consideration of circular economy factors in China

Abstract The complex relationship between carbon emissions and economic development has become a global issue. In China, the pressure to reduce carbon emissions is very great because the responsibility of four participants for economic activities has not been able to break away from the linear economic model of ‘produce-consume-discard’. In this paper, four categories of participants, namely extractors/producers, manufacturers, consumers and recyclers, are classified according to the life cycle framework, and the impact of their activities on carbon emission reduction is analysed taking into account circular economy factors. The results of the study show that during the rapid development of China’s economy from 2005 to 2021, there is a significant correlation between carbon emission reduction and the activity behaviour of the four participants with consideration of circular economy factors. In particular, the activity behaviours of the extractors/producers, manufacturers and consumers have a very strong correlation with the carbon emission reduction. Our findings indicate that China should continue to exert efforts in the existing circular economy model to achieve the double carbon goals.

Milking the label: The impact of category labels on consumer liking and category fit of non-dairy milks

The influence of labels on expectation is well documented, but the effect of category labels on consumer perception is not well understood. The fast pace of emerging product categories highlights the importance of ensuring that category labels meet consumer expectations. To examine the impact of category expectations on liking, 384 consumers were assigned one of four conditions where they were told they were drinking either milk (broad condition), plant-based milk (intermediate condition), almond milk (specific condition), or given no information (control group). All groups were given six almond milks and asked to rate their liking on a 9-point hedonic scale. Consumers in the broad, intermediate, and specific conditions were also asked to rate category fit on a 9-point Likert scale. Category label had a significant impact on overall liking, with the specific condition having significantly higher liking than the control, as well as a significantly higher liking than the intermediate and control conditions. External preference mapping showed that the sensory drivers of liking were constant across the four conditions, but the sensory drivers of category fit changed depending on which category condition participants were part of. In the broad condition, sweetness and vanilla flavour contributed to category fit. Creaminess was more important for the intermediate condition, while nutty and roasted flavours determined category fit for the specific condition. Our results suggest that increased specificity in category labels can increase product liking, underscoring the importance of sensory evaluation for understanding the link between category labels and consumer perception.

How do renters survive unaffordability? Household-level impacts of rent burden in Los Angeles

ABSTRACT Prior research shows that households reduce consumption of basic necessities in response to an increasing rent burden. However, questions remain regarding the interrelated, cumulative tactics renters use to survive amidst declining affordability. We address these critical questions by leveraging data from a door to door household survey in South and Central Los Angeles. First, we find that rent-burdened households (those paying over 30% of their income on rent) were more likely to reduce consumption and that adjustments in many consumption categories had persisted for years. Second, rent-burdened households undertook impactful functional adjustments, including working more hours and altering their homes to accommodate more residents. Severely rent-burdened households were 10.4 percentage points more likely to accommodate additional residents than those paying between 30 and 50% of income toward rent. Finally, we find that many households made both functional adjustments and consumption cutbacks simultaneously, which demonstrates the cumulative hardships caused by housing unaffordability.

Product Characteristics and Emotions to Bridge the Intention-Behavior Gap in Green Food Purchasing

Promoting environmentally friendly behaviors is a pivotal strategy in addressing the climate crisis. The food industry’s impact on pollution and resource consumption underscores the importance of fostering eco-sustainable food consumption, which can significantly benefit the environment. However, despite the global surge in green purchase intentions, a noticeable discrepancy persists between these intentions and actual purchasing behavior. This study aimed to investigate the influence of various factors on the likelihood of purchasing green food. An online survey was administered to Italian adult consumers (n = 832, 66% female, aged 18–84 years), collecting sociodemographic data and assessing emotions related to green purchases, perceptions of green food characteristics, intention to buy green food, and frequency of green food purchases. Through cluster analysis, three distinct consumer categories emerged: Coherent Buyers (individuals willing to buy green food and actively doing so), Coherent Non-Buyers (individuals who have no intention to buy green food and do not buy it), and Non-Buyers with Favorable Intentions (individuals expressing willingness to buy green food but not following through with purchases). Results from multinomial logistic regression analysis revealed that several factors influenced the likelihood of being categorized in the other two categories, as opposed to the Coherent Buyers one. These factors included younger age, a lower sense of pride associated with purchasing green products, and considering healthiness, natural content, and eco-sustainability of food less important and familiarity of green food more important. These findings provide valuable insights for marketers and policymakers, facilitating efforts to bridge the gap between green food intentions and behaviors and promote a shift toward a more eco-sustainable dietary pattern.

Dietary Live Microbes Intake Associated With Biological Aging and Mortality.

This observational study aimed to investigate associations between dietary live microbe intake and mortality, as well as biological aging. Adults from the 1999-2018 National Health and Nutrition Examination Survey were categorized into low, medium, and high dietary live microbe groups. Foods with medium and high live microbe content were aggregated into a medium-high consumption category. The outcomes included all-cause, cardiovascular, and cancer mortality, along with biological age (BA) acceleration assessed by the Klemera-Doubal method (KDM) and PhenoAge. Multiple regression analyses and mediation analyses were conducted to assess associations, adjusting for potential confounders. A total of 34 133 adults were included in our analyses. Over an average follow-up period of 9.92 years, 5462 deaths occurred. In multivariate adjusted models, every 100g of medium-high group foods consumed was associated with reduced all-cause mortality (hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.91 to 0.97, p < .001) and cardiovascular mortality (HR 0.91, 95% CI 0.86 to 0.96, p < .001), but not with cancer mortality (HR 1.01, 95% CI 0.95 to 1.07, p = .768). Every 100g medium-high group foods consumption was associated with decreased KDM-BA acceleration (fully adjusted regression coefficient -0.09, 95% CI -0.15 to -0.04, p = .001) and PhenoAge acceleration (fully adjusted regression coefficient -0.07, 95% CI -0.11 to -0.03, p < .001). Mediation analysis showed that BA acceleration partially mediated live microbes-mortality associations. Our results suggest that higher dietary live microbe intake is associated with lower mortality risk and slower biological aging. However, further research is needed to verify these findings.

The ‘meathybrid’ concept: bridging the gap between texture, taste, sustainability and nutrition

SummaryPositioned midway between traditional meat and plant‐based options, hybrid alternatives cater to a broader consumer category due to the intersection of flavours, textures and ethical considerations. This review aims to provide a current landscape and forthcoming challenges of hybrid options, exploring their formulation, processing, distinctive features, consumer acceptance and sustainability aspects. Even though there is no standard definition of the ‘meathybrid concept’, scientists and industrials explored different ingredients including purified proteins or whole vegetables/grains/seeds to formulate palatable hybrid products maintaining comparable sensory features to meat. Consumers' attraction to hybrid meat products is mostly related to taste, sustainability and nutritional aspects. Future challenges for hybrid options may include optimising production scalability, ensuring consistent quality and taste and effectively communicating the benefits of hybrid products to diverse consumer segments. Additionally, ongoing research and development efforts will be crucial in enhancing hybrid alternatives' sensory attributes, nutritional profiles and environmental sustainability.

The Influence of Vision Impairment on the Measurement of Cognition in Older Adults in India: Findings From LASI-DAD.

Prior investigations have not considered whether poor vision biases cognitive testing. However, such research is vital given increasing evidence that vision impairment (VI) may be an important modifiable risk factor for dementia, particularly in low- and middle-income settings where the prevalence of VI is high. This study employed data from 3784 participants in Wave 1 of the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (LASI-DAD) who underwent both visual acuity and cognitive function testing. We used multiple indicators and multiple causes models to assess differential item functioning (DIF; eg, bias) in cognitive testing by objectively measured distance and near VI. Multivariable linear regression was used to model the association between VI and cognitive factor scores before and after DIF adjustment. Analyses were performed for general cognition and separate cognitive domains, corresponding to memory, language/fluency, executive functioning, and visuospatial performance. Models were adjusted for demographic, health, and socioeconomic covariates. Participants in our sample were 60 and older. Most participants with VI were 60-69 years old (59.6%) and 50.8% were female. Individuals experiencing both distance and near VI tended to be older, have lower educational attainment, be married, reside in rural settings, and belong to lower consumption and BMI categories. Both distance and near VI were associated with poorer cognition before and after DIF-adjustment. Differences between DIF-unadjusted and -adjusted scores were small compared to the standard error of measurement, indicating no evidence of meaningful measurement differences by VI. In well-conducted large-scale surveys, bias in cognitive testing due to VI is likely minimal. Findings strengthen previous evidence on the association between VI and dementia by showing that such associations are unlikely to be attributable to vision-related measurement error in the assessment of cognitive functioning.

Associations between cooking method of food and type 2 diabetes risk: A prospective analysis focusing on cooking method transitioning

Cooking process for food significantly impacts household air and increases exposure to endocrine disruptors such as acrylamide, consequently affecting human health. In the past 30 years, the transformation of cooking methods to high-temperature thermal processing has occurred widely in China. Yet the transition of cooking methods on the onset of type 2 diabetes (T2D) remains unclear, which may hinder health-based Sustainable Development Goals. We aimed to estimate the associations between dietary intake with different cooking methods and T2D risk. We included 14,745 participants (>20 y) from the China Health and Nutrition Survey (1991–2015). Food consumption was calculated using three consecutive 24-h dietary recalls combined with both individual participant level and household food inventory. Cooking methods, including boiling, steaming, baking, griddling, stir-frying, deep-frying, and raw eating, were also recorded. The consumption of baked/griddled and deep-fried foods was positively associated with 39% and 35% higher of T2D risk by comparing the highest with the lowest category of food consumption, respectively. The use of unhealthy cooking methods for processing foods including baked/griddled and deep-fried foods was attributable for 15 million T2D cases of the total T2D burden in 2011, resulting in a medical cost of $2.7 billion and was expected to be attributable for 39 million T2D cases in 2030, producing a medical cost of $223.8 billion. Replacing one serving of deep-fried foods and baked/griddle foods with boiled/steamed foods was related to 50% and 20% lower risk of T2D, respectively. Our findings recommend healthy driven cooking methods for daily diet for nourishing sustainable T2D prevention in China.

Impact of Alcohol-Induced Facial Flushing Phenotype on Alcohol Consumption Among Korean Adults: 2-Year Cross-Sectional Study.

The alcohol-induced facial flushing phenotype (flushing) is common among East Asians. Despite a small intake of alcohol, they experience heightened levels of acetaldehyde, a group-1 carcinogen, which, in turn, causes unpleasant symptoms such as redness, acting as a robust protective mechanism against consuming alcohol. However, some individuals with this genetic trait exhibit weakened alcohol restraint, which increases the risk of developing alcohol-related cancers, such as esophageal and head or neck cancer, by several times. Although this flushing phenomenon is crucial for public health, there is a paucity of studies that have comprehensively investigated the effect of flushing or its genotype on alcohol consumption in a large group of East Asians while controlling for various sociodemographic and health-related variables at a country level. This 2-year cross-sectional study aims to explore the effect of flushing on drinking behavior in Koreans and to examine whether the effect varies across sociodemographic and health-related factors. We used data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2019 and 2020 conducted by the Korea Disease Control and Prevention Agency. Our sample comprised 10,660 Korean adults. The study investigated the association of 26 variables, including flushing, with drinking frequency and amount. The effect of flushing was examined with and without adjusting for the other 25 variables using multinomial logistic regression analysis. In addition, we tested the interaction effect with flushing and conducted a simple effect analysis. We used complex sample design elements, including strata, clusters, and weights, to obtain unbiased results for the Rao-Scott χ2 test, 2-tailed t test, and multinomial logistic regression analysis. The suppressive effect of flushing was significant (P<.001) across all pronounced categories of alcohol consumption in 2019. The ranges of standardized regression slopes and odds ratios (ORs) were -6.70≥β≥-11.25 and 0.78≥OR≥0.50 for frequency and -5.37≥β≥-17.64 and 0.73≥OR≥0.36 for amount, respectively. The effect became somewhat stronger when adjusted for confounders. The effect also exhibited an overall stronger trend as the severity of alcohol consumption increased. The β values and ORs were consistently smaller in 2020 compared to the previous year. A simple effect analysis revealed a diminished alcohol-suppressive effect of flushing on alcohol consumption for specific groups (eg, those with low levels of education, limited family support, physical labor, or health-related issues). Our findings suggest that flushing suppresses drinking in Koreans overall but has little or no effect in certain susceptible populations. Therefore, health authorities should conduct targeted epidemiological studies to assess drinking patterns and disease profiles, particularly regarding alcohol-related cancers, and establish effective preventive measures tailored to this population.

Artificially sweetened beverage consumption and all-cause and cause-specific mortality: an updated systematic review and dose-response meta-analysis of prospective cohort studies

BackgroundArtificially sweetened beverages (ASB) are consumed globally, but their impact on overall health remains uncertain. We summarized published associations between ASB intake with all-cause and cause-specific mortality.MethodsWe searched Medline, Embase, Web of Science, and Cochrane CENTRAL databases until August 2023. Random effect meta-analysis was conducted to calculate pooled risk ratios (RRs) and 95% confidence intervals (95%CIs) for highest versus lowest categories of ASB consumption in relation to all-cause and cause-specific mortality. Linear and non-linear dose-response analyses were also performed.ResultsOur systematic review and meta-analysis included 11 prospective cohort studies. During a median/mean follow-up period of 7.0 to 28.9 years, 235,609 deaths occurred among 2,196,503 participants. Intake of ASB was associated with higher risk of all-cause and CVD mortality with pooled RRs (95%CIs) of highest vs. lowest intake categories of 1.13 (1.06, 1.21) (I2 = 66.3%) for all-cause mortality and 1.26 (1.10, 1.44) (I2 = 52.0%) for CVD mortality. Dose-response analysis revealed a non-linear association of ASB with all-cause mortality (pnon−linearity = 0.01), but a linear positive association with CVD mortality (pnon−linearity = 0.54). No significant association was observed for ASB intake and cancer mortality. Moreover, a secondary meta-analysis demonstrated that replacing 1 serving/day of sugary sweetened beverages (SSB) with ASB was associated with 4–6% lower risk of all-cause and CVD mortality. Per NutriGrade, the evidence quality for associations between ASB intake with all-cause and CVD mortality was moderate.ConclusionsHigher intake of ASB was associated with higher risk of all-cause and CVD mortality, albeit a lower risk than for SSB.Systematic review registrationPROSPERO registration no.

Impact of Different Extraction Processes on the Quality of Shea Butter (Vitellaria paradoxa) Produced by Women in the Northern Regions of Côte d’Ivoire

Aims: The objective of this study is to evaluate the influence of different extraction processes on the quality of butter produced in each region. Study Design: The production of shea butter (Vitellaria paradoxa) is an activity widely practiced in the North of Côte d’Ivoire using different processes, specific to each region. This leads to the great variability of butters on the market, calling into question the control of the quality of butter and limiting its valorization in the food and even technological fields. Place and Duration of Study: Laboratory of Food Biochemistry and Tropical Products Technology, between June 2021 and July 2022. Methodology: To do this, the physical and chemical properties of butter from four (4) regions of northern Côte d'Ivoire (Poro, Bagoué, Tchologo and Hambol) were studied to judge their qualities. These different butters were then subjected to an organoleptic test in order to evaluate their levels of acceptability by a panel trained for this purpose. Results: The results obtained reflect a significant influence of all the processes on the physical and chemical properties of the butter, particularly on the quality criteria. We observe a high level of oxidation between 10.347±0.01 meq/kg (Poro) and 10.430±0.011 meq/kg (Bagoué), an accentuated acidity where the acid number varied from 10.763±0.01 mg/g (Tchologo) to 11.373±0.01 mg/g (Bagoué), leading to high free fatty acid contents of 5.986±0.02% (Bagoué), 5.891±0.01% (Poro), 5.771±0.010% (Hambol) and 5.665±0.010 (Tchologo) and an impurity phase to monitor ranging from 0.168±0.002 to 0.192±0.001. These impurity indices mostly show non-compliance for direct consumption (category I butter). However, some conformities are recorded when butters are downgraded to category II intended for the food industry with vigilance on these said conformities. Finally, the organoleptic analysis revealed a strong correlation of the general appreciation of butters with the taste but also texture and color which were influenced by the processes. Conclusion: This study highlighted the impact of all the extraction processes on the shea butter produced in Côte d’Ivoire, particularly on the peroxide indices and free fatty acids; confirmed by sensory testing.

Associations of sugary beverage consumption with chronic obstructive pulmonary disease, asthma, and asthma–chronic obstructive pulmonary disease overlap syndrome: a prospective cohort study

BackgroundThe associations between specific types of sugary beverages and major chronic respiratory diseases remain relatively unexplored. ObjectivesThis study aimed to investigate the associations of sugar-sweetened beverages (SSBs), artificially sweetened beverages (ASBs), and natural juices (NJs) with chronic obstructive pulmonary disease (COPD), asthma, and asthma–chronic obstructive pulmonary disease overlap syndrome (ACOS). MethodsThis prospective cohort study included 210,339 participants from the UK Biobank. Sugary beverage intake was measured in units (glasses/cans/cartons/250 mL) through 24-h dietary questionnaires. Logistic regression and Cox proportional hazards models were used to analyze the prevalence and incidence, respectively. Quantile G-computation was used to estimate the joint associations and relative contributions of the 3 types of sugary beverages. ResultsOver a median follow-up of 11.6 y, 3491 participants developed COPD, 4645 asthma, and 523 ACOS. In prevalence analysis, certain categories of SSB and NJ consumption were associated with increased asthma prevalence, while high ASB consumption (>2 units/d) was linked to higher risks of all 3 outcomes. In incidence analysis, high SSB consumption (>2 units/d) was associated with incident COPD (hazard ratio [HR]: 1.53; 95% confidence interval [CI]: 1.19, 1.98) and asthma (HR: 1.22; 95% CI: 0.98, 1.52). Dose‒response relationships were observed for ASB consumption with all 3 outcomes (continuous HR: 1.98; 95% CI: 1.36, 2.87, for COPD; continuous HR: 1.65; 95% CI: 1.24, 2.20, for asthma; and continuous HR: 2.84; 95% CI: 1.20, 6.72, for ACOS). Moderate NJ consumption (>0–1 unit/d) was inversely associated with COPD (HR: 0.89; 95% CI: 0.82, 0.97), particularly grapefruit and orange juice. Joint exposure to these beverages (per unit increase) was associated with COPD (HR: 1.15; 95% CI: 1.02, 1.29) and asthma (HR: 1.16; 95% CI: 1.06, 1.27), with ASBs having greater positive weights than SSBs. ConclusionsConsumption of SSBs and ASBs was associated with increased risks of COPD, asthma, and potentially ACOS, whereas moderate NJ consumption was associated with reduced risk of COPD, depending on the juice type.
