Association of anthropometric variables with therapy-induced cardiotoxicity in women with breast cancer: a pilot study for a randomized clinical trial.

BACKGROUND: Doxorubicin (DOX) has been widely used in the treatment of breast cancer, but it is directly associated with late-onset cardiovascular disease (CVD). Whether anthropometric, food intake or other risk factors together with DOX-based chemotherapy can increase the risk of developing cardiotoxicity remains uncertain. We examined the association between anthropometric variables with doxorubicin-induced cardiotoxicity in women with breast cancer. METHODS: Twenty-six women (53.7 ± 9.6 y) undergoing DOX-based chemotherapy (408.3 ± 66.7 mg/m2) participated in the study. We collected data on body composition (bioimpedance), dietary intake (24 h) and cardiac function (echocardiographic assessment of left ventricular ejection fraction, LVEF). All measurements were taken at baseline, one month of treatment completion and one-year follow-up after start of treatment. DOX-induced cardiotoxicity was defined as ≥ 10% absolute decrease in LVEF. Thus, the participants were then grouped as DOX-induced (DIC) or non-DOX-induced (non-DIC) cardiotoxicity. Data are shown as mean ± SD (standard deviation). We performed comparisons between the two groups using Student's t-test for independent samples or Generalized Estimating Equations (groups + 3 evaluation time points) with Bonferroni post-hoc test. Lastly, the correlations were analyzed using Pearson correlation; p < 0.05 for all tests. RESULTS: At baseline the participants' body mass index (BMI) was 29.9 ± 7.9 kg/m2 and LVEF was 67.4 ± 6.2%. Seven of them (26.9%) developed therapy-induced cardiotoxicity (ΔLVEF - 3.2 ± 2.6%; p < 0.001). Postmenopausal status and family history of CVD were more prevalent in the DIC group than non-DIC group. We found no consistent BMI changes in the groups over time. Interestingly, the non-DIC group showed a small increase in visceral fat at treatment completion and increased waist circumference at one-year follow-up compared to baseline. These same changes were not seen in the DIC group. We also observed a pattern of correlation of some anthropometric variables with LVEF: the more unfavorable the body composition the more pronounced the LVEF decrease at one-year follow-up, though not associated with cardiotoxicity. CONCLUSIONS: Our study did not provide sufficient evidence to support that anthropometric variables, food intake or other risk factors increase the risk of developing cardiotoxicity. However, there are apparent trends that need to be further investigated in larger samples.

Determinants of underweight among lactating mothers in public health facilities, Siraro District, Southern Ethiopia: unmatched case-control study.

BACKGROUND: Ethiopia is reported to have one of the highest prevalence of underweight among lactating mothers in Africa. In our study setting, the nutritional report from the district health office showed a high number of underweight lactating mothers and recurrent malnutrition problems. However, the determinants of underweight among lactating mothers were not well understood in our study setting. The study aimed to assess the determinants of underweight among lactating mothers in public health facilities of Siraro District, Southern Ethiopia. METHODS: Unmatched case control study was conducted among 390 (130 cases and 260 controls) lactating mothers in public health facilities of Siraro District from April 30 to May 30/2022. Cases were lactating mothers with BMI < 18.5 kg/m2 and controls were mothers whose BMI was ≥ 18.5 kg/m2. To identify the determinants of underweight, bivariate and multivariable binary logistic regression analysis were carried out. The final model was interpreted using adjusted odds ratio (AOR), along with a 95% confidence interval (CI). Significance was declared at p-value < 0.05. RESULT: Multivariable logistic regression analysis revealed that having; antenatal care visits [AOR = 0.43, 95% CI (0.26,0.72)], latrine availability [AOR = 0.50,95% CI (0.27,0.93)], poor food consumption score [AOR = 5.40, 95% CI (3.15,9.27)], inadequate dietary diversity score [AOR = 1.66, 95% CI (1.20,2.78)], medium [AOR = 3.34, 95% CI (1.52,7.33)] and poor wealth index [AOR = 6.32, 95%CI(3.12,12.81)] were significantly associated with being underweight among lactating mothers. CONCLUSION: Antenatal care visits, latrine availability, poor food consumption scores, inadequate dietary diversity score, medium and poor wealth index were the determinants of underweight. A multi-sectoral approach focusing on latrine construction, economic empowerment and food diversification, as well as ongoing awareness creation, is essential to increase the nutritional status of lactating mothers and break the vicious cycle of malnutrition.

Shaping sustainable consumption: Quebec consumers' knowledge and beliefs about the environmental impacts of food.

There is growing evidence that shifts in food consumption have the potential to mitigate the environmental impacts of food systems. Yet, although Canadians are increasingly concerned about climate change, changes towards more sustainable food consumption patterns are not widely observed. Understanding consumers' perspective on these issues is crucial for bridging this gap between individual behaviors and collective concerns. This study explores the knowledge, understanding and beliefs of Quebec consumers regarding the environmental impacts of food and their potential for shaping sustainable food consumption. A representative sample of consumers (N=978) answered an online questionnaire assessing their factual knowledge and investigating their views of food systems impacts. Results indicate low levels of knowledge and highlight widely shared beliefs regarding food systems. Consumers tended to overestimate the role of transport in food's environmental footprint and believe that reducing transport or eating local foods are the most effective ways to improve environmental sustainability. Likewise, consumers tend to underestimate the impact of production, as well as solutions that could effectively reduce this impact. The findings reveal a need for improved literacy and awareness of the environmental impacts of food, thereby highlighting the importance of effective information and education strategies to shape sustainable food consumption habits.

Changes in food consumption and nutrition intake of rural residents in central China.

Food security and diet diversity is essential to sustainable food system all over the world. As the income of rural residents achieves great increase, the structure of food consumption and food diversification face significant change. Rural residents' food consumption and nutrients intake worth more attention. Chinese government has been striving to achieve sustainable development in rural areas. We conducted this study to explore area-level practices aiming at achieving food and nutrition security in rural China. In order to search for the change principle and main influencing factors of residents' food consumption, three rural areas in Henan Province were selected. According to the data obtained from the Henan Province Bureau of Statistics, changes in food consumption from 2012 to 2021 in three rural areas were analyzed in this study. This study led to the following remarkable results: (1) The per capita consumption of poultry, meat, sugar, and eggs of the three rural residents has increased much more than that of other food items. (2) In the three rural areas, the proportions of grains, vegetables, liquor, and edible oils have decreased overall. The proportions of other categories, such as poultry, meat, and fruits, have increased. (3) The rural residents' per capita nutrition intake has increased remarkably. The results provide some empirical foundation for local government who need suggest that rural residents should control their intake of high-energy food, such as poultry, meat, and sugar. This study has significant policy implication for achieving sustainable goals in rural areas of China.

Association of food group with the changes in sarcopenia parameters over 1 year in older outpatients in a frailty clinic.

PURPOSE: This study investigated the relationship between food group and the changes in sarcopenia parameters in 1 year among older outpatients. METHODS: A prospective cohort study conducted between July 2017 and April 2021 included patients aged ≥ 65 years attending a frailty clinic. Food group consumption adjusted for energy and body weight was conducted using a self-administered dietary history questionnaire. Ordinal logistic regression analysis was used to examine the association between tertiles of adjusted food group consumption and outcomes, including a handgrip strength decline, prolonged five-time chair stand test (5CST), decreased skeletal muscle mass index (SMI), and decreased gait speed in 1 year. Covariates included age, sex, height, energy intake, number of comorbidities, and the Baecke activity score. RESULTS: In the analysis of 165 participants (mean age 77.6 ± 6.1 years, 107 women), individuals with higher consumption of sugar and sweeteners had a significantly increased risk for handgrip strength decline (OR 2.46, 95% CI 1.15-5.23, P = 0.020) and prolonged 5CST (OR 3.14, 95% CI 1.38-7.13, P = 0.006). Higher consumption of beverages increased the risk of handgrip strength decline (OR 2.30, 95% CI 1.11-4.76, P = 0.025). Conversely, higher legume consumption decreased the risk of SMI reduction (OR 0.35, 95%CI 0.16-0.76, P = 0.008), higher fruit consumption reduced the risk of prolonged 5CST time (OR 0.29, 95% CI 0.13-0.67, P = 0.004), and higher green yellow vegetables consumption decreased the risk of reduced gait speed (OR 0.38, 95% CI 0.17-0.84, P = 0.017). CONCLUSION: Sugar, sweeteners, and beverages are associated with worsened sarcopenia parameters, whereas consumption of legumes, vegetables, and fruits is associated with a lower risk.

Micronutrient Consumption Among Postpartum Women and Food Insecurity.

This study aimed to assess the prevalence of inadequate micronutrient intake and its risk factors among women one year after giving birth. 240 women of reproductive age were assessed. Micronutrient intake was assessed from two 24-hour records at three stages (3-6-12 months after childbirth). A generalized linear mixed-effect model was used to assess the factors associated with food intake. A prevalence of inadequate micronutrient intake was observed, with the exception of iron. Intake was lower among food-insecure women (zinc: ß -0.13; iron: ß -0.09; vitamin C: ß -0.44). The postpartum period and food insecurity remained statistically associated with lower food consumption in the explanatory models tested.

Are vegetarians' diets inherently healthy? Ultra-processed food consumption is associated with overweight among vegetarians: the brazilian survey on the health, food, and nutrition of vegetarians.

This cross-sectional study investigated ultra-processed food (UPF) consumption and its association with overweight among Brazilian vegetarian adults (n = 925). Data were collected using a self-administered structured online questionnaire. The prevalence of overweight was 26.2% (95% confidence interval [CI] 23.3-29.1). The median UPF consumption was 1.8 times/day (1.0-3.1 interquartile range [IQR]). The multivariable generalised linear model identified an increase in overweight probability as the UPF intake - categorised into quintiles - increases (prevalence ratio [PR] 1.08 [95%CI 1.01-1.17]). Additionally, age (PR 1.03 [95%CI 1.02-1.04]), eating more than three meals/day away from home (PR 1.56 [95%CI 1.08-2.23]), duration of vegetarianism (PR 0.98 [95%CI 0.97-0.99]) and living in the wealthiest regions in the country (PR 1.35 [95%CI 1.06-1.71]) were associated with overweight. Although vegetarians have a lower average UPF intake and overweight prevalence than the general population, UPF exposure can still lead to excessive weight gain or maintenance. This study endorses generalising the Brazilian Dietary Guidelines for the vegetarian population.

Existem diferenças entre homens e mulheres quanto aos fatores associados à ingestão de cálcio? / Are there differences between men and women with respect to the factors associated with calcium intake?

Resumo O objetivo do artigo é verificar se existem diferenças entre os sexos quanto aos fatores que se associam à ingestão de cálcio. Estudo realizado com dados de inquérito de saúde, em amostra de 1.640 indivíduos de 20 anos ou mais residentes no município de Campinas-SP. A ingestão de cálcio foi obtida por meio de um recordatório de 24 horas (R24h) e analisada segundo variáveis sociodemográficas, de comportamentos de saúde, frequência de refeições e índice de massa corporal (IMC); a presença de associações foi verificada por meio de testes de regressão linear múltipla. O perfil de fatores associados à ingestão de cálcio diferiu entre os sexos. A prática de atividade física no contexto de lazer só se associou ao consumo de cálcio no sexo masculino, enquanto cor da pele, tabagismo, renda, excesso de peso e frequência do café da manhã mostraram associação apenas no sexo feminino. Escolaridade e realização de lanches intermediários mostraram-se associadas à ingestão de cálcio em ambos os sexos. A análise aponta segmentos da população feminina e masculina em que a importância da ingestão de cálcio precisa ser mais enfatizada; além disso, alerta para a importância do desenvolvimento de análises de saúde estratificadas por sexo em decorrência de diferentes padrões comportamentais que prevalecem entre os sexos.

Abstract The scope of this article is to verify if there are differences in factors associated with calcium intake between men and women. It is based on a study conducted with data from a health survey in a sample of 1641 individuals aged 20 years or more living in the urban area of the city of Campinas, in the State of São Paulo. Calcium intake was obtained from a 24-hour recall (24hr recall method) and analyzed according to sociodemographic variables, health behavior, frequency of meals and body mass index (BMI). The existence of associations was verified by multiple linear regression tests, and it was detected that the profile of associated factors differed between genders. Physical exercise in the leisure context was only associated with calcium intake in males, while skin color, smoking, income, overweight/obesity, and frequency of having breakfast only revealed an association in females. Schooling and having snacks were associated with calcium intake in both sexes. The analysis of the associated factors indicates segments of the female and male population in which the importance of calcium intake needs to be more closely examined. Furthermore, it highlights the importance of conducting health analyses stratified by sex due to the different behavioral patterns that prevail between the sexes.

The association between food preferences, eating behavior, and body weight among female university students in the United Arab Emirates.

Introduction: This cross-sectional study investigated the associations between lifestyle, eating habits, food preferences, consumption patterns, and obesity among female university students in the United Arab Emirates (UAE). Methods: Approximately 4,728 participants, including both Emirati and Non-Emirati students (International Students). Data collection involved face-to-face interviews and anthropometric measurements, showing an interrelated relationship between food preferences and obesity among female university students. Results: While sociodemographic factors and lifestyle habits contribute to obesity, this study uniquely focuses on the role of food preferences and food consumption patterns in body weight status. The findings reveal a significant correlation between the intake of high-sugar beverages-such as milk, juices, soft drinks, and energy drinks-and an increased risk of overweight and obesity among both Emirati and Non-Emirati populations. Notably, milk consumption was particularly associated with obesity in non-Emirati populations (F = 88.1, p < 0.001) and with overweight status in Non-Emiratis (F = 7.73, p < 0.05). The consumption of juices and soft drinks was linked to obesity. Additionally, a significant preference for fruits and vegetables among overweight and obese students was observed, indicating a trend toward healthier food choices. However, there was also a clear preference for high-calorie, low-nutrient foods such as processed meats, sweets, and salty snacks. Fast food items like burgers, fried chicken, fries, pizza, shawarma, chips, and noodles were significantly correlated with increased body weight status, especially shawarma, which showed a notably high correlation with both obesity and overweight statuses (F-values of 38.3 and 91.11, respectively). Conclusion: The study indicated that food choices shape weight-related outcomes is important for designing effective strategies to promote healthier dietary patterns.

Starvation and re-feeding of Gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) co-cultured with glasswort (Salicornia europaea) in a polyculture aquaponic system.

The aim of this study was to evaluate the effect of starvation and refeeding on the growth and food intake of gilthead seabream (Sparus aurata) and seabass (Dicentrarchus labrax) and on the growth and nitrogen uptake of glasswort (Salicornia europaea) in a polyculture aquaponic system under 12 ppt salinity for 75 days. Nine small-scale autonomous aquaponic systems were used, each containing 10 gilthead seabreams (average weight of 6.33 ± 0.73 g and average length of 5.73 ± 0.72 cm) and 10 seabasses (5.82 ± 0.77 g and 6.35 ± 0.45 cm), as well as five glasswort plants. Three fish feeding treatments were performed, a control (A), in which fish were fed daily until satiation, and two fasting treatments for 4 (B) and 7 days (C). Fish growth performance was significantly lower (p < 0.05) in the C treatment for both species compared to treatments A and B. Food consumption (FC) and feed conversion ratio (FCR) were significantly higher (p < 0.05) in treatment C. Glasswort growth performance was significantly higher in treatment C (p < 0.05). The results showed that the 4-day food-deprived fish were similar to the control fish by achieving partial compensatory growth. The more extended fasting period (7 days) resulted in significantly lower growth performance. The lipid and nitrogen retention levels in both species were significantly lower in food-deprived fish than in the control fish both before and during compensatory growth. The results suggest that a feeding schedule involving starvation-refeeding cycles is a promising feed management option for these species in polyculture aquaponic systems. The effect of food deprivation was also significantly beneficial (p < 0.05) for the growth performance of glasswort compared to the control treatment.

Taste or Health: The Impact of Packaging Cues on Consumer Decision-Making in Healthy Foods.

According to the theory of dietary regulation, consumers frequently encounter conflicts between healthiness and tastiness when selecting healthy foods. This study explores how packaging cue that highlight "tasty" versus "healthy" affect consumers' intentions to purchase healthy food. After an Implicit Association Test (IAT) confirmed a perceived lack of tastiness in health foods in the preliminary test, Study 1 analyzed pricing and packaging details of the top 200 most-popular items in each of the ten healthy food categories on a major online shopping platform. Results showed that products with taste-focused cues commanded higher prices, indicating stronger consumer acceptance of healthy foods marketed as delicious. To address the causality limitations of observational studies, Study 2 used an experimental design to directly measure the impact of these cues on purchase intentions and perceptions of energy, healthiness, and tastiness. Findings revealed that taste-focused cues significantly boosted purchase intentions compared to health-focused cues, although they also diminished the perceived healthiness of the products. Moreover, in the control group exposed to unhealthy food options, health-emphasized packaging also increased purchase intentions, indicating that consumers seek a balance between healthiness and tastiness, rather than prioritizing health alone. Study 3 further explored the impact of cognitive load over these cue influences, revealing a heightened inclination among consumers to purchase healthy products with taste-focused cue under high cognitive load state. These insights have direct implications for food packaging design, suggesting that emphasizing a balance of taste and health benefits can effectively enhance consumer engagement. The study, which conducted in China, also opens avenues for future research to explore similar effects, maybe in different cultural contexts, different consumer groups, and under varied cognitive conditions.

Turkish version of a short nutrition literacy scale for young adults: cultural adaptation and validation.

Background: Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent. Purpose: The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023). Methods: This research involved 115 young adults from Istanbul Gelisim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups. Results: As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ2/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults. Conclusion: The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.

The influence of environmental cleanliness on food perceptions.

Background: Getting consumers to adopt healthier eating habits continues to be a puzzle for marketers and policymakers all over the globe. Nevertheless, research continues to identify factors that can influence consumers' food consumption. Aim: The purpose of this research is to explore how one relatively unexplored factor, namely the cleanliness of the surrounding environment, can affect perceptions and consumption. Methods: An online survey experiment presenting participants with either a clean or dirty environment scenario and asking subsequent questions about their dining experience was utilized. Results: Participants in a clean (vs. dirty) environment perceived their food to be healthier, fresher, and of higher quality, relative to a dirty environment. This effect, in turn, mediated the relationship between condition and perceptions of meal quality. Conclusion: Clean environmental conditions, though not directly related to the food products provided at food venues, can nevertheless have a strong influence on consumers' dining experience.

Assessment of Biochemical, Inflammatory Biomarkers and Ultra-Processed Food Consumption in Children with Small Intestinal Bacterial Overgrowth: A Cross-Sectional Study.

OBJECTIVE: This study evaluated anthropometric, biochemical, and inflammatory biomarkers, as well as dietary intake in Brazilian children diagnosed with small intestinal bacterial overgrowth (SIBO) and compared them with their counterparts without SIBO. METHODS: This was a cross-sectional study with 106 children aged 7 to 10 years. A glucose-hydrogen breath test was performed to diagnose small intestinal bacterial overgrowth (SIBO). Anthropometric and dietary characteristics were assessed. Blood samples were collected and serum biochemical parameters and cytokines were measured. RESULTS: The occurrence of SIBO was 13.2%. Age, BMI, BMI/age WC, BFP, sex and biochemical markers were similar between SIBO-positive and SIBO-negative children (p > 0.05). High consumption of ultra-processed foods tended to be higher in SIBO-positive compared to SIBO-negative children (47.8 ± 8.2 vs. 42.6 ± 9.5, p = 0.06). Serum levels of IL-17 were higher in SIBO-positive than in SIBO-negative children [69.5 (5.4-125.7) vs. 53.4 (2.3-157.7), p = 0.03], while serum levels of IL-10 were lower in SIBO-positive than in SIBO-negative children [2.3 (0.6-7.2) vs. 5.7 (0.5-30.8), p = 0.04]. Finally, in a logistic regression adjusted for sex, BMI and age, consumption of ultra-processed foods (p = 0.03) and IL-6 levels (p = 0.003) were found to contribute to the occurrence of SIBO. CONCLUSION: this study identified for the first time an occurrence of 13% of SIBO in children living in the northeastern region of Brazil and showed that consumption of ultra-processed foods and serum levels of IL-6 may influence the occurrence of the SIBO in the pediatrics population.

The U.S. Food and Drug Administration (FDA) Food Disaggregation Database (FDA-FDD): a new tool for U.S. dietary exposure assessment.

Dietary exposure to a food chemical (e.g. contaminant, nutrient, or other natural constituent) is a function of the concentration of the chemical in foods and the quantity of each food consumed. Exposures to food chemicals can be estimated using intake data from What We Eat in America (WWEIA), the food consumption survey portion of the National Health and Nutrition Examination Survey (NHANES). To estimate exposures to chemicals in foods consumed by NHANES/WWEIA respondents, the consumption data must be mapped to chemical concentration data on the same or similar foods. However, food chemical data are generally not available on all the foods and food mixtures that are reported in NHANES/WWEIA. To address this, we developed the FDA Food Disaggregation Database (FDA-FDD), a 'recipe' database with estimates of ingredient percentages. FDA-FDD allows mapping to food chemical data based on ingredients in NHANES/WWEIA foods rather than on food mixtures, resulting in more accurate exposure estimates. Using FDA-FDD, FDA mapped over 11,000 NHANES/WWEIA foods to FDA's Total Diet Study (TDS) foods. FDA-FDD is available as part of a publicly available interactive application that also allows access to the TDS mapping.

Regional food consumption in Italy, a life cycle analysis.

Urbanization and globalization have led to an increasing concern and focus on the sustainability of the food sector, particularly in discussing the composition of consumers' diets. This study examines Italian consumption habits, categorizing them into four macro-geographical areas (North-West, North-East, Center, South, and Islands), utilizing public data obtained from surveys including 3323 individuals, and assesses their environmental impacts through the application of the Life Cycle Assessment methodology. The findings unveil distinct dietary patterns across Italian macro-regions, indicative of cultural disparities, and present avenues for promoting environmentally sustainable dietary choices. The study identifies meat consumption as the primary environmental concern across all macro-regions, with fish emerging as a secondary contributor to particulate matter formation. Pork and poultry exhibit notable impacts within toxicity-related categories. Additionally, the research underscores challenges in data collection, notably the absence of a site-specific Italian database, and underscores the necessity for more recent consumption data to accurately capture contemporary Italian dietary habits. Finally, the study demonstrates that addressing the issue from a macro-regional perspective allows for more targeted and dedicated cultural interventions.

Oxidative stability and nutritional quality of stored Linum usitatissmium L. and Argania spinosa L., oil blends: Chemical compositions, properties and nutritional value.

Identification of the chemical compositions of fatty acids and tocopherols shows the high content of linum usitatissimum oil (LO) by linolenic acid 55.3735% and γ-tocopherol 570.927 mg/kg, while argania spinosa oil (AO) is known by the dominance of oleic acid 47.77% followed by linoleic acid 31.08% as well as tocopherols by γ-tocopherols 687.485 mg/kg and δ-tocopherols 51.035 mg/kg. This difference in compositions enables us to enrich the low-stability oil and monitor its behavior during storage at a specific time and under specific conditions. In this study, pure linum usitatissimum and argania spinosa oils extracted by cold pressing as well as their formulations at proportions of (LO: AO) respectively: (80:20; 60:40, 50:50; 40:60; 20: 80) were oxidized at 60 °C for 28 days of storage, during which time the pure oils and blends were assessed for oxidative stability by studying their different fatty acid and tocopherol profiles and physicochemical characteristics such as acidity, peroxide value and chlorophyll and carotenoid pigments, as well as nutritional indexes such as the atherogenic index (AI), the thrombogenic index (TI), and the hypocholesterolemic: hypercholesterolemic ratio (HH), ω3:ω6 ratio, also the oxidative susceptibility (OS), and oxidazability value (Cox), and total phenolic compounds (TPC).

Bridging the Intention-Behavior Gap in Organic Food Consumption: Empirical Evidence from China.

The transition to a low-carbon economy emphasizes the importance of green and low-carbon consumption; yet, there is often a discrepancy between consumers' intentions and their actual behavior regarding organic foods. This study aims to identify strategies to bridge this gap. The research model of organic food consumption intention and behavior is constructed, and a structural equation model is used to test the research hypotheses based on a valid sample of 480 residents of Guangdong Province through an online questionnaire survey. Further, the intention‒behavior gap is defined and its determinants are investigated through multiclass logistic regression. Finally, we categorize and forecast the alignment between consumption intentions and behaviors using machine learning algorithms. The results reveal that attitudes, social interactions, and cognitive information play crucial roles in aligning intentions with behaviors. By enhancing social information exchange or improving cognitive understanding, consumers can reduce their intention‒behavior discrepancy. This research offers valuable policy recommendations for fostering green consumption among residents from various perspectives.

Quantitative Assessment of the Inadequate Intake of Macronutrients, Minerals, and Vitamins Associated with Ultra-Processed Food Consumption.

Studies indicate that ultra-processed food (UP) consumption correlates negatively with essential vitamin and mineral intake and positively with sodium and lipid intake. The objective of this study was to explore the relationship between UP consumption and deviations from nutritional guidelines. An observational, cross-sectional analytical study was conducted on a probability sample of manufacturing workers in the state of Rio Grande do Norte, Brazil. Food consumption was assessed with a 24 h recall survey, and nutrient intake inadequacies were calculated as the difference between individuals' intake of energy, macronutrients, minerals and vitamins, and the dietary reference intakes for individuals of the same sex and age group, and then analyzed for trends across the percentage contribution of UP to total energy intake with nonparametric multiple regression adjusted for covariates. The study included 921 workers from 33 industries, 55.9% male, with a mean age of 32 years. Overall, the study population exhibited deficits in energy, all macronutrients, and in some micronutrients. With increasing UP contribution to total energy intake, there is a trend towards a greater intake of energy (p < 0.001), total, saturated, monounsaturated, and trans fats (p < 0.001), n6-polyunsaturated fatty acids (p = 0.03), carbohydrates (p < 0.001), calcium (p = 0.008), and manganese (p < 0.001), thiamin (p < 0.001), and vitamin B6 (p = 0.01); however, this comes with a negative consequence in terms of reducing the protein consumption (p = 0.037), fiber (p = 0.035), copper (p = 0.033), and vitamin E (p = 0.002) intake. The results show that correcting energy and micronutrient deficiencies by increasing UP consumption can also lead to a decrease in diet quality.

Food Consumption Inequalities in Primary Care in a Large Metropolis.

The aim of this study was to examine the association between health vulnerability and food consumption according to the NOVA classification within primary care in a major Brazilian city. A cross-sectional study was conducted among adults over 20 years old. These participants were part of a representative sample from the Health Academy Program (PAS) in Belo Horizonte, Brazil. We evaluated socio-demographic variables, self-reported illnesses, perceived health and quality of life, and the length of participation in PAS. Health vulnerability was gauged through the Health Vulnerability Index (HVI), which is calculated for each census sector and classified as low, medium, and high/very high. On the other hand, food consumption was determined by evaluating the average consumption described in a 24 h diet recall (24HR) and categorizing it under the NOVA classification: culinary preparations, processed foods, and ultra-processed foods (UPFs). The average calorie intake was 1429.7 kcal, primarily from culinary preparations (61.6%) and UPFs (27.4%). After adjustments, individuals residing in high/very high-HVI areas consumed more culinary preparations (ß = 2.7; 95%CI: 4.7; 0.7) and fewer UPFs (ß = -2.7; 95%CI: -4.7; -0.7) compared to those from low-vulnerability areas. PAS participants residing in more vulnerable areas reported healthier dietary habits, consuming more homecooked meals and fewer UPFs. These findings underscore the importance of concentrating efforts on promoting and preserving healthy eating habits and emphasizing the value of home cooking in the most vulnerable regions.
