RESUMO

Introduction: The increase in ultra-processed foods (UPFs) intake has raised concerns about its impact on public health. Prospective observational studies have reported significant associations between higher intake of UPFs and adverse health outcomes. The aim of this study is to determine whether these associations could be confirmed in randomized controlled trials (RCTs). Methods: We conducted a systematic review to analyze the evidence on the effects of UPFs intake on health. A systematic search was conducted in Medline, Embase, Web of Science, Scopus, LILACS, and CENTRAL up to April 22, 2024. RCTs in English, Spanish, and Portuguese evaluating the health effects of interventions to modify UPFs intake were included. The certainty of evidence was determined using the GRADE methodology. Results: Three educational intervention studies and one controlled feeding trial were included, evaluating the effect of reducing the consumption of UPFs (455 participants, median follow-up, 12 weeks). No significant effects were observed in 30 out of the 42 outcomes evaluated. The controlled feeding trial in adults with stable weight showed a reduction in energy intake, carbohydrates, and fat (low certainty of evidence), as well as in body weight, total cholesterol, and HDL cholesterol (moderate certainty of evidence). In the educational intervention studies, a reduction in body weight and waist circumference was observed (low certainty of evidence) in women with obesity, as well as improvement in some dimensions of quality of life (very low certainty of evidence). No significant changes were observed in children and adolescents with obesity, while in overweight pregnant women, the consumption of UPFs was not reduced, so the observed benefits could be attributed to other components of the intervention. Conclusion: Interventions aimed at reducing the consumption of UPFs showed benefits on some anthropometric and dietary intake outcomes, although significant effects were not observed for most of the evaluated outcomes. The limited number and significant methodological limitations of the studies prevent definitive conclusions. Further well-designed and conducted RCTs are needed to understand the effects of UPF consumption on health.Systematic review registration: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023469984.

RESUMO

BACKGROUND: Anxiety symptoms are factors that directly affect eating habits, but this interference can be heterogeneous depending on the nutritional status of the individuals. OBJECTIVES: To analyze whether the presence of anxiety symptoms at the beginning of the pandemic influenced the change in food consumption according to its purpose and extent of processing during a one-year follow-up and whether this association occurs equally with excess weight and without excess weight university students. METHODS: This longitudinal study was carried out with 583 university students from a public Higher Education Institution (HEI) in Brazil. The Generalized Estimating Equation (GEE) was used to verify whether anxiety symptoms were associated with changes in food consumption over time. RESULTS: The results showed that previous moderate/severe anxiety symptoms were associated with an increased frequency of consumption of both fresh or minimally processed foods (ß: 0.2 95%CI: 0.1; 0.7 p = 0.013) and ultra-processed foods (ß: 5.6 95%CI: 1.8; 17.7 p = 0.003), but with different magnitudes. In university students who were not excess weight, previous moderate/severe anxiety symptoms were associated with a reduction in the frequency of consumption of fresh or minimally processed foods (ß: -2.0 95%CI: -3.5; -0.5 p = 0.008), while in those who were excess weight, there was an increase in consumption of ultra-processed foods (ß: 4.5 95%CI: 2.2; 6.8 p < 0.001). CONCLUSION: This study confirms the influence of anxiety symptoms on food consumption according to the extent and purpose of processing. In addition, these results emphasize the role of psychological distress in the university population, and that this factor can affect excess weight and without excess weight individuals differently.

RESUMO

PURPOSE: We quantified levels of ultra-processed food (UPF) consumption and investigated consumption patterns in a representative sample of UK adolescents. METHODS: We used data from 4-day food diaries from adolescents in the UK National Diet and Nutrition Survey (NDNS) (2008/09-2018/19). UPF were identified using the NOVA classification. We estimated the percentage of Total Energy Intake (%TEI) and the absolute weight (grams). Linear regression models quantified differences in UPF consumption across survey years and its association with participant's individual characteristics. This was an analysis of the repeated cross-sectional data from the UK NDNS Rolling Programme waves 1-11 (2008/09-2018/19). A total of 2991 adolescents (11-18y) with complete information on dietary intake were included. RESULTS: Mean UPF consumption was 861 (SD 442) g/d and this accounted for 65.9% (SD 13.4%) of TEI. Between 2008 and 2019, mean UPF consumption decreased from 996 to 776 g/d [ - 211 (95%CI - 302; - 120)] and from 67.7% to 62.8% of TEI [ - 4.8% (95%CI - 8.1; - 1.5)]. Higher %TEI was consumed by adolescents with lower socioeconomic status; white ethnicity and living in England North. A higher weight of UPF consumption (g/d) was associated with being male, white, age 18y, having parents with routine or manual occupation, living in England North, and living with obesity. CONCLUSION: Average energy intake from UPF has decreased over a decade in UK adolescents. We observed a social and regional patterning of UPF consumption, with higher consumption among adolescents from lower socioeconomic backgrounds, from a white ethnicity and living in England North. Our findings suggest inequalities associated with UPF intake and factors that might lie beyond individual choice.

RESUMO

Ethical food consumption has gained significant attention in the past years, reflecting a societal shift towards ethical behavior. Our study examines the evolution of ethical food consumption research over the past three decades, aiming to map its transformation. We identified key trends, influential contributors, and major thematic clusters through a bibliometric analysis, employing VOSviewer (v.1.6.18) for bibliometric visualization, focusing on citation networks and keyword o-occurrences to reveal the field's structure and dynamics. We made extensive use of the Web of Science database, where we selected 1096 relevant articles and review papers. Our analysis shows a notable rise in publications starting in 2005, with a peak in 2022, indicating increased scholarly interest in the topic. The findings underscore the importance of integrating empathy and human values into ethical food consumption, highlighting the critical roles of animal welfare, sustainability, and social justice. Despite a strong pro-ethical attitude among consumers, a significant "attitude-behavior gap" persists, emphasizing the need for strategies that bridge this divide. Our results emphasize the importance of interdisciplinary efforts to align ethical practices with broader societal goals, offering valuable insights for future research and policy-making to promote sustainable and ethical food consumption worldwide.

RESUMO

BACKGROUND: Morocco is currently undergoing rapid changes in diets and lifestyles, influenced by globalization and urbanization, leading to a shift away from the Mediterranean diet (MedDiet) toward Western diets. OBJECTIVE: Describe and explore the food consumption patterns of the population of Kenitra province and their adherence to the MedDiet using a validated survey. METHOD: The current cross-sectional study involved 442 respondents from Kenitra province, comprising individuals aged 18 and above. The survey included a combination of closed and open-ended questions regarding food consumption patterns and socio-demographic characteristics. Adherence to the MedDiet was assessed using the Panagiotakos method to calculate the MedDiet score (MDS). Additionally, each participant's adherence to the MedDiet was evaluated using a method based on Martínez-González's approach. RESULTS: The results indicate that 31% of the participants eat vegetables, 28% eat fruits, and 19% eat wholegrain bread daily. Furthermore, 58% regularly use olive oil in their cooking. Eating out of home (OOH) was high, with popular places being restaurants and cafes (70%), fast food outlets (20%), and workplace canteens (7%). Overall, participants showed moderate adherence to the MedDiet, with a mean MDS of 36.3 ± 19.7. CONCLUSIONS: Promoting healthy eating habits is crucial in Kenitra. With moderate consumption of nutrient-dense foods and the popularity of the MedDiet, targeted interventions and educational initiatives can promote healthy dietary behaviors, improving overall public health.

RESUMO

The long-term impacts of radiocontaminants (and the associated risks) for ecosystems are still subject to vast societal and scientific debate while wildlife is chronically exposed to various sources and levels of either environmental or anthropogenic ionizing radiation from the use of nuclear energy. The present study aimed to assess induced phenotypical responses in both male and female gammarids after short-term continuous γ-irradiation, acting as a typical well-characterized genotoxic stressor that can interact directly with living matter. In particular, we started characterizing the effects using standardized measurements for biological effects on few biological functions for this species, especially feeding inhibition tests, molting, and reproductive ability, which have already been proven for chemical substances and are likely to be disturbed by ionizing radiation. The results show no significant differences in terms of the survival of organisms (males and females), of their short-term food consumption which is linked to the general health status (males and females), and of the molting cycle (females). In contrast, exposure significantly affected fecundity (number of embryos produced) at the highest dose rates for irradiated females (51 mGy h-1) and males (5 and 51 mGy h-1). These results showed that, in gammarids, reproduction, which is a critical endpoint for population dynamics, is the most radiosensitive phenotypic endpoint, with significant effects recorded on male reproductive capacity, which is more sensitive than in females.

RESUMO

Introduction: Evidence points toward the early life being crucial for preventing nutrition-related diseases. As promotion of healthier food preferences in toddlerhood and preschool age might still modulate the trajectories of disease risk, understanding diet in these age groups is necessary. The objective was to analyze food consumption and diet quality of 1-5-year-old children living in Germany in relation to age and sex. Methods: Data from 890 children, a subsample of the representative, cross-sectional Children's Nutrition Survey to Record Food Consumption (KiESEL) conducted by the German Federal Institute for Risk Assessment in 2014-2017, were analyzed. Dietary data were collected using food records (3 consecutive plus 1 independent day). Diet quality was evaluated against the German food-based dietary guidelines (FBDG). Results: Consumption of unfavorable foods (e.g., sweets, soft drinks) exceeded the recommended maximum of 10% of energy intake (E%) by a multiple in all age and sex groups (medians: 24.8-35.8 E%). Preschoolers consumed more unfavorable foods than toddlers and boys more than girls. More than half of the children exceeded the recommendation for meat intake (medians: 2.3-3.2% of the total food consumption (%TFC) vs. 2 %TFC), especially preschoolers. In nearly all children, vegetable consumption was too low (medians: 4.2-4.5 %TFC vs. 12 %TFC). Also, milk/milk product consumption was below recommendations, more so in preschoolers (median: 12.0 %TFC ♂, 11.9 %TFC ♀ vs. 18 %TFC) than in toddlers (median: 16.1 %TFC ♂, 19.6 %TFC ♀). In toddlers and preschoolers with overweight or obesity, adherence to dietary recommendations of these food groups was largely similar to that of the total sample. Overall, 5-year-olds showed an unhealthier dietary pattern than 1-year-olds, which already emerged at age 2 years and became more evident at age 3 years. Discussion: An adverse dietary pattern arises and even deteriorates at a very young age, showing sex-specific aspects. High attention from public health and research needs to be given to toddlerhood and even earlier life phases, e.g., to develop more age-specific FBDGs, aiming at reducing unhealthy food consumption.

RESUMO

BACKGROUND: The rates of obesity, undernutrition, and other non-communicable diseases are on the rise among Lebanese adults. Therefore, it is crucial to evaluate the food consumption habits of this population to understand diet quality, analyze consumption trends, and compare them to healthy diets known to reduce risks of non-communicable diseases. AIM: To evaluate the food consumption patterns, energy intake, as well as macro- and micro-nutrient intake among a nationally representative sample of Lebanese adults aged 18-64 years old. METHODS: A cross-sectional study was carried out from May to September 2022 involving 444 participants from all eight Lebanese governorates. Sociodemographic and medical information was gathered through a questionnaire, food consumption was evaluated using a validated FFQ and 24 h recall, and anthropometric measurements were recorded. RESULTS: There was a notable lack of adherence to three healthy diets (Mediterranean, EAT-Lancet, USDA) among Lebanese adults. Their dietary pattern is characterized by high energy, added sugars, sodium, and saturated fat intake while being low in healthy fats, vitamin A, D, and E. Adult women are falling short of meeting their daily calcium, vitamin D, iron, and vitamin B12 requirements, putting them at increased risk of anemia, osteoporosis, and other health issues. Grains and cereals were the most consumed food groups, and most participants were found to be overweight or obese. CONCLUSIONS: In conclusion, the results highlight the need for public health policies and interventions aimed at encouraging Lebanese adults to make healthier food choices and transition towards diets like the Mediterranean, EAT-Lancet, or USDA diet. These diets have been shown to promote overall health and wellbeing.

RESUMO

CONTEXT: Assessing the overall sustainability of a diet is a challenging undertaking requiring a holistic approach capable of addressing the multicriteria nature of this concept. OBJECTIVE: The aim was to identify and summarize the multicriteria measures used to assess the sustainability characteristics of diets reported at the individual level by healthy adults. DATA SOURCES: Articles were identified via PubMed, Scopus, and Web of Science. The search strategy consisted of key words and MeSH terms, and was concluded in September 2022, covering references in English, Spanish, and Portuguese. DATA EXTRACTION: This systematic review followed the PRISMA guidelines. The search identified 5663 references, from which 1794 were duplicates. Two reviewers independently screened the titles and abstracts of each of the 3869 records and the full-text of the 144 references selected. Of these, 7 studies met the inclusion criteria. DATA ANALYSIS: A total of 6 multicriteria measures were identified: 3 different Sustainable Diet Indices, the Quality Environmental Costs of Diet, the Quality Financial Costs of Diet, and the Environmental Impact of Diet. All of these incorporated a health/nutrition dimension, while the environmental and economic dimensions were the second and the third most integrated, respectively. A sociocultural sustainability dimension was included in only 1 of the measures. CONCLUSION: Despite some methodological concerns in the development and validation process of the identified measures, their inclusion is considered indispensable in assessing the transition towards sustainable diets in future studies.

RESUMO

OBJECTIVES: The aim of this study was to investigate the impact of a mindfulness intervention (IG) compared to an inactive control group (CG) on explicit and implicit attitudes toward vegetarian and meat-based foods, nutrition behavior measures, trait mindfulness and wellbeing. METHODS: In the IG (N = 66), we implemented a mindfulness-based intervention consisting of eight weekly group sessions online, along with an additional half-day session held on campus. The CG (N = 71) received no intervention or training. We employed a pre-/post-intervention design involving questionnaires (trait mindfulness, wellbeing, sustainable nutrition behavior scale), an online supermarket scenario, as well as an explicit rating task and an implicit association task using pictures of vegetarian and meat-based foods. Additionally, a voluntary follow-up testing was conducted two months after the final group session. RESULTS: No intervention effects were observed on explicit and implicit attitudes, wellbeing, or nutrition behavior measures. However, there was an increase in trait mindfulness within the IG. Exploratory cross-sectional findings indicated that trait mindfulness facets such as "Acting with Awareness" and "Outer Awareness", along with explicit attitudes, were significant predictors of self-reported sustainable consumption behavior. Additionally, sex and explicit attitudes were identified as significant predictors of vegetarian consumption behavior in the online supermarket task. CONCLUSION: Our findings could not substantiate previous claims regarding the potential causal effects of mindfulness practice on sustainable consumption behavior, specifically in the realm of sustainable and vegetarian nutrition, as well as subjective wellbeing. Future studies may benefit from implementing longer-term mindfulness-based interventions and considering other potential decisive factors, such as connectedness to nature and others. Integrating training elements focusing on these specific variables into the intervention could be valuable.

RESUMO

The round goby Neogobius melanostomus is a notoriously invasive fish originating from the Ponto-Caspian region that in recent decades has successfully spread across the globe. One of its primary impacts is direct predation; in addition, when entering new ecosystems, the round goby is likely to become a food resource for many higher native predators. However, little is known either about the indirect effects of predators on the round goby as prey or its feeding behaviour and activity. The non-consumptive effect of the presence of higher native predators presumably plays an important role in mitigating the impact of non-native round gobies as mesopredators on benthic invertebrate communities, especially when both higher- and mesopredators occupy the same habitat. We tested the food consumption probability and gut evacuation rates in round gobies in response to chemical signals from a higher predator, the European eel Anguilla anguilla. Gobies were placed individually in experimental arenas equipped with shelters and exposed to water from a tank in which (a) the higher predator had actively preyed on a heterospecific prey, earthworms Lumbricus sp. (the heterospecific treatment; HS); (b) the higher predator had fed on round gobies (the conspecific treatment; CS); or (c) the water was provided as a control treatment (C). To ensure exposure to the chemical stimuli, this study incorporated the application of skin extracts containing damaged-released alarm cues from the CS treatment; distilled water was used for the remaining treatments. No significant differences were observed in either the food consumption probability or gut evacuation rate in the tested treatments. Despite the lack of reaction to the chemical stimuli, round gobies did exhibit high evacuation rates (R = 0.2323 ± 0.011 h-1; mean ± SE) in which complete gut clearance occurred within 16 h regardless of the applied treatment. This rapid food processing suggests high efficiency and great pressure on resources regardless of the presence or not of a higher predator. These findings hint at the boldness of round gobies, which did not exhibit any pronounced threat sensitivity. This would seem to suggest great efficiency in food processing and a potential competitive advantage over local native species when colonising new ecosystems, irrespective of the presence of native predators. Our study did not detect any non-consumptive effect attributable to the higher predator, given that the feeding activity of the invasive round goby was not altered.

RESUMO

BACKGROUND: There has been a significant rise in the number of individuals diagnosed with type 2 diabetes mellitus (T2DM), with the condition reaching epidemic proportions globally. This study examined the dietary pattern of a sample of Saudi Arabian adults with T2DM compared to control non-diabetics. METHODS: Data from 414 participants, 207 control and 207 T2DM was analyzed. Anthropometric measurements, foods intake such as vegetables, fruits, whole grains, fried foods, sweetened juice, sweets, and pastries consumption as well as physical activity were obtained by an interview-survey. RESULTS: The consumption of vegetables, green and leafy vegetables, starchy vegetables, fruits, proteins, and milk was significantly higher in the diabetics (p< 0.0001 for all and p<0.01 for starchy vegetables). Of the case group, 79.7% of them consumed whole-wheat bread while 54.6% of them consumed low fat milk (p<0.0001). There was a significant decrease in the percentage of cases who consumed discretionary foods and sweetened juices and soft drinks (24.1%), avoided sweets (75.8%) and pastries (37.1%), (p<0.0001). There were also significant increases in the percentages of participants who use healthy fat (as olive oil) in the case group (78.7%) (p<0.001). There was a significant increase in the percentage of diabetics who followed a diet to lose weight (15%) (p<0.05). The majority of the two study groups were physically inactive (control 95.2% & case 94.2%). CONCLUSIONS: The results of this study provide insight on that diabetics generally follow a healthy diet, yet their engagement in physical activity may not be optimal.

RESUMO

In the context of rural Bangladesh, we assess whether agriculture training alone, nutrition Behavior Communication Change (BCC) alone, combined agriculture training and nutrition BCC, or agriculture training and nutrition BCC combined with gender sensitization improve: (a) production diversity, either on household fields or through crop, livestock or aquaculture activities carried out near the family homestead and (b) diet diversity and the quality of household diets. All treatment arms were implemented by government employees. Implementation quality was high. No treatment increased production diversification of crops grown on fields. Treatment arms with agricultural training did increase the number of different crops grown in homestead gardens and the likelihood of any egg, dairy, or fish production but the magnitudes of these effect sizes were small. All agricultural treatment arms had, in percentage terms, large effects on measures of levels of homestead production. However, because baseline levels of production were low, the magnitude of these changes in absolute terms was modest. Nearly all treatment arms improved measures of food consumption and diet with the largest effects found when nutrition and agriculture training were combined. Relative to treatments combining agriculture and nutrition training, we find no significant impact of adding the gender sensitization on our measures of production diversity or diet quality. Interventions that combine agricultural training and nutrition BCC can improve both production diversity and diet quality, but they are not a panacea. They can, however, contribute towards better diets of rural households.

RESUMO

Several countries have introduced public health product taxes with the objective of reducing the absolute amount of consumption of unhealthy food and tackling obesity. This study aims to estimate the long-term impact of the Hungarian public health product tax introduced in 2011. To achieve this, a unique consumer purchase dataset was analysed to examine daily fast-moving consumer goods purchases from a representative sample of 2,000 households from 2010 to 2018. The results indicate that the tax has been fully reflected in consumer prices. A decline in consumption was observed initially, consistent with previous experiences in Hungary and other countries. However, over time, the data suggests a recovery and even an increase in line with the growth of disposable income. The proportion of taxed products in total fast-moving consumer goods purchases increased from 5.9 % (95 % CI: 5.7 % to 6.0 %) in 2010 to 7.4 % (95 % CI: 7.3 % to 7.6 %) in 2018. Furthermore, the tax has contributed to increased inequality as low-income households spend a higher proportion of their total expenditure on it. Although taxes on unhealthy foods have proven effective in the short-term, they may not be adequate for reducing overall consumption in the long-term, particularly as disposable income increases. In conclusion, implementing complex interventions is necessary to achieve sustainable positive changes in dietary habits.

RESUMO

OBJECTIVE: To analyze food carbon footprint and its socio-demographic disparities among adults in China. METHODS: A total of 12 777 adults aged 18 years and above from the China Health and Nutrition Survey in 2018 who have completed dietary and socio-demographic data were analyzed. The information of food intake were collected by 24 h recalls combined with the weighing of household seasonings. Food consumption was converted into energy intake by the China Food Composition Table. Carbon footprint of 26 food groups were calculated by the food carbon footprint database based on life-cycle assessment(LCA), multinomial logit model was used to analyze the association of socio-demographic factors and food carbon footprint. RESULTS: Average food carbon footprint were decreased with increasing age while increased with increasing income and education levels, and was higher among male than that among female, was higher among urban residents than that among rural residents, was higher in the south than that in the north. Multinomial logit analysis showed that compared with people aged 18-44, the likelihood of occurring high carbon footprint in 60y and above group were 29%(OR=0.71, 95%CI 0.61-0.83) lower than that occurring low carbon footprint. Women were 11%(OR=0.89, 95%CI 0.81-0.99) and 25%(OR=0.75, 95%CI 0.67-0.84) less likely to appear medium and high carbon footprint than low carbon footprint, compared with their male counterparts. In comparison to people living in cities, rural dwellers were 24%(OR=0.76, 95%CI 0.69-0.85) and 38%(OR=0.62, 95%CI 0.55-0.70) less likely to appear medium and high carbon footprint than low carbon footprint. People in the south were 3.89 times(95%CI 3.52-4.30) and 11.35 times(95%CI 10.01-12.88) more likely to occur medium and high carbon footprint than low carbon footprint, compared with people in the north. Participants were more likely to occur medium carbon footprint and high carbon footprint with the increasing income level(OR>1), and were more likely to occur high carbon footprint with the increasing education level(OR>1). CONCLUSION: The food carbon footprint of adults in China in 2018 show different socio-demographic disparities, gender, income and education level are significant factors.

RESUMO

BACKGROUND: Eating habits formed during adolescence greatly influence the maintenance of health in adulthood. With the recent development of social media and easy access to the Internet, adolescents watch plenty of food videos, particularly Mukbang and Cookbnag(eating show)content. This media genre's impact on food choices has been covered in several studies; however, studies on unhealthy eating habits directly related to adolescents' exposure to eating shows are insufficient. METHODS: For this study, we used data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 and finalized 50,451 participants. The extent of exposure to eating show media over the course of a week, as well as the consumption of fast food, sugar-sweetened beverages (SSBs), and high caffeinated beverages within that week were measured through self-reporting questionnaires. We classified the participants into two groups based on their frequency of watching eating shows. A multiple logistic regression analysis was performed to investigate the association between eating show and unhealthy food consumption. RESULTS: For both males and females, eating show exposure was strongly associated with the consumption of fast food (male: OR:1.37, 95% CI:1.26-1.49; female: OR:1.46, 95% CI:1.36-1.57), SSB (male: OR:1.42, 95% CI:1.26-1.60; female: OR:1.51, 95% CI:1.35-1.70), and high caffeinated beverage (male: OR:1.30, 95% CI:1.23-1.37; female: OR:1.24, 95% CI:1.18-1.31). It was observed that both sexes were more likely to frequently eat unhealthy food than students who did not watch eating shows. CONCLUSION: Among Korean adolescents, students exposed to eating shows, which primarily aim to entertain, were more likely to consume fast food, SSBs, and high caffeinated beverages. Therefore, this study's findings suggest that eating show could influence adolescents' food choices, highlighting the need for interest in emerging cultures and corresponding health policies.

RESUMO

Background: Food insecurity and hunger are global concerns further exacerbated by the unprecedented COVID-19 pandemic. There is a need to understand the depth of this impact, especially among smallholder farmers, and recognize specific coping strategies that offered resilience to inform preparedness in future. The present cross-sectional study assessed the impact of the second wave of COVID-19 pandemic on different dimensions of food security among smallholder farmers of Ho indigenous community of Jharkhand, India. It also explored potential resilient attributes of their food systems. Results: Most of the respondents (67.2%) reported reduced food consumption at the household (HH) level. Majority faced difficulty in accessing food from different food sources; however, easier access to government food security programmes was highlighted. Around 40% reported change in their ability to purchase farming inputs. Market vendors reported disruptions in food procurement owing to travel restrictions; however, no change was reported for home-produced foods in agricultural lands/kitchen gardens. Prices of indigenous foods produced locally decreased/remained same; however, for cereals, pulses, and other HH staples, prices increased during second wave. Difficulty in accessing wild food environment (OR: 1.7, CI 0.40, 7.75), change in food prices (OR: 19.9, CI 5.25, 76.02), decrease in HH income (OR: 9.2, CI 2.99, 28.60) were found to be significantly associated with reduction in HH food consumption (p < 0.01). The coping strategies adopted by the community included sale of cultivated and wild produce in local weekly markets to ensure additional income. Conclusions: The findings highlight the need to reinforce the traditional ecological knowledge of the Ho community and focus on practices around their food systems, engrained into their socio-cultural ecosystems that may offer resilience against future stresses. In addition, the need of systemic support to ensure the social and economic well-being of the community needs to be prioritized.

RESUMO

Background: Dietary changes form an important component of the sustainability transition of food systems but could be hindered by the cost of sustainable diets. Objectives: This study aimed to characterize the cost of nutritionally adequate and culturally acceptable diets with low-greenhouse gas emissions (GHGEs) in Finland. Methods: Two optimization models were built to find diets complying with nutritional and emissions requirements. The first model minimizes diet cost and the second one deviation from current diets. Both are calibrated to Finnish sociodemographic groups using dietary intake data, household budget survey data (for prices), and life cycle assessment coefficients (for GHGE). Three scenarios are simulated: "Health only" imposes only compliance with nutritional constraints, whereas "Health and GHGE-33%" and "Health and GHGE-50%" impose, in addition, minimum reductions in GHGE. Results: Minimum cost diets have a low-carbon footprint [-65% (-73%) for females (males)] and low cost [-69% (-73%) for females (males)] when compared with current diets but lack diversity and cultural acceptability. The more culturally acceptable health-only minimum deviation diets are marginally less costly and have a lower climate impact than baseline diets across all population groups. Reducing GHGE results in a substantial decrease in the cost of the minimum deviation diets. The lower cost of the minimum deviation diets with reduced GHGE results from both intercategory and intracategory substitutions. Conclusions: Affordability is not the key obstacle to the adoption of nutritionally adequate and lower GHGE diets, but cultural acceptability is. Reducing the climate footprint of diets can generate side benefits in terms of nutrition and affordability, which confirms that dietary change should be central to the sustainability transition of the Finnish food system. However, more attention should be paid to the issues of taste, convenience, social norms, and other aspects determining the cultural acceptability of sustainable diets.

RESUMO

The relationship between organic food consumption, awareness of reducing ecological footprint, and orthorexia nervosa (ON) tendencies has yet to be explored in detail. This study aimed to determine factors related to organic food consumption and ON tendencies in young adults. Also, the relationship between organic food consumption, awareness of reducing ecological footprint, and ON tendencies was investigated. This study was conducted with 887 young adults (58.4% female, 41.6% male, aged 18-25 years, mean age 20.8 ± 2.55 years). Study data were obtained with a web-based questionnaire. The questionnaire included socio-demographic characteristics, anthropometric measurements, the Organic Food Consumption Scale (OFC), ORTO-11, and the Awareness Scale for Reducing Ecological Footprint (ASREF). While 17.2% were overweight or obese, 74.9% had a normal body weight. There were no differences by sex in terms of ORTO-11, OFC, and ASREF total scores (p > .05). Significant positive correlations were found between ASREF and OFC (p < .001), while negative correlations were found for ORTO-11 and OFC (p < .001). A higher ASREF and increased ON tendencies predicted increased organic food consumption (p < .05). Furthermore, higher organic food consumption behaviors and awareness of reducing ecological footprint predicted increased ON tendencies (p < .05). Findings from this study will contribute to a deeper understanding of the factors associated with organic food consumption and ON tendencies among individuals. By shedding light on the interplay between ecological awareness, organic food consumption, and orthorexic tendencies, policymakers and health professionals can develop targeted interventions to promote sustainable and healthy food consumption.

RESUMO

BACKGROUND: The aim of this study was to evaluate evolution of ultra-processed food intake and recurrent weight gain in patients who underwent Roux-en-Y gastric bypass. MATERIALS AND METHODS: This study is an observational longitudinal study that evaluated patients who underwent metabolic and bariatric surgery at four time points: before surgery and at 3, 12, and 60 months after surgery. Anthropometric and dietary intake data were collected through two 24-h dietary recalls. All foods consumed were classified according to degree of processing. Recurrent weight gain was considered the difference between current weight and nadir weight. RESULTS: The sample consisted of 58 patients with a mean age of 38.7 ± 8.9 years and 68% female. After 60 months, mean excess weight loss and recurrent weight gain were 73.6 ± 27.2% and 22.5 ± 17.4%. Calorie and macronutrient intake decreased significantly between the pre-surgery period, and 3 and 12 months post-surgery; however, there was no significant difference after 60 months. In relation to food groups or macronutrients, no difference was observed between the pre-surgery period and 60 months post-surgery. The contribution of unprocessed or minimally processed foods to calorie intake gradually decreased after 3 months post-surgery. CONCLUSION: The profile of dietary intake after 60 months of metabolic and bariatric surgery tends to approach that of the pre-surgery period. The contribution of unprocessed and minimally processed foods to calorie intake decreased after 60 months, while ultra-processed food contribution increased.
