This study aimed to evaluate healthy eating practices and their relationship with the workers' quality of life and physical activity during the COVID-19 pandemic. This was a cross-sectional investigation involving workers in the city of Curitiba, southern Brazil. The study was conducted through the application of an online questionnaire. The data were evaluated using non-parametric tests and fitting a logistic regression model. A total of 123 workers participated in the study, most of them male (53.2%), aged between 31 and 40 years (42.2%), with a predominance of workers with postgraduate degrees (62.6%, n = 77), and the majority of workers (68.2%, n = 84) were performing their professional activities remotely for at least one day during the week, and 73.2% (n = 90). It was observed that 52.8% had excellent healthy eating practices, and the older their age and the greater the practice of physical activity (time and frequency), the better the workers' healthy eating practices. When assessing quality of life, the lowest average score for healthy eating practices was in the domain of social relationships. A direct relationship of older age, social relationships, and the practice of physical activity with the best individuals' healthy eating practices was detected. Considering that remote work continues to be adopted post-pandemic, evaluating the dietary practices, physical activity, and quality of life of workers is necessary to understand this new labour phenomenon.","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11428102/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142336963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study analysed the relationships among trace mineral intake, DL, and CAD in middle-aged and older adults living in Shika town, Ishikawa prefecture, Japan. This study included 895 residents following the exclusion of those with genetic risk carriers for familial hypercholesterolemia. Trace mineral intake was evaluated using the brief-type self-administered diet history questionnaire. Interactions were observed between DL and CAD with zinc (p = 0.004), copper (p = 0.010), and manganese intake (p < 0.001) in a two-way analysis of covariance adjusted for covariates such as sex, age, body mass index, and current smokers and drinkers. Multiple logistic regression analysis showed that zinc (odds ratio (OR): 0.752; 95% confidence interval (CI): 0.606, 0.934; p = 0.010), copper (OR: 0.175; 95% CI: 0.042, 0.726; p = 0.016), and manganese (OR: 0.494; 95% CI: 0.291, 0.839; p = 0.009) were significant independent variables for CAD in the dyslipidaemic group.

A cross-sectional study was conducted and dietary data was collected using a 24-h dietary recall method from a total of 2555 Lithuanian adults. Medians, 25th and 75th percentiles were calculated. The diet of Lithuanian adults was found insufficient as the energy intake from fats exceeded the recommended norms, while the energy intake from carbohydrates was below the lower range. The intakes of dietary fibre and most vitamins and minerals were insufficient. Men, compared to women, had a statistically higher total energy intake and energy intake from fats, and a higher intake of dietary fibre. Younger adults, compared to older ones, had statistically lower intakes of energy from fats, including saturated fats, and lower intakes of sodium chloride. Respondents with primary education, compared to those who had attained a higher degree of education, had a statistically lower intake of total energy and dietary fibre. Study showed that intakes of majority of nutrients in the diet of the adult Lithuanian population are not in compliance with the recommended daily intakes. Continuous nationally representative studies into food consumption and nutrient intake of the adult Lithuanian population must be carried out to assess the changes in the population's diet and the effectiveness of policies aimed at promoting healthy diets.","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11513885/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142523327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare how different ways of expressing total protein intake may influence its relationships with diet quality and obesity. Usual protein intake was estimated from the 2011-12 Australian National Nutrition and Physical Activity Survey (n = 7637 adults, ≥19 years), expressed in grams (g/d), percent energy (%EI), and grams per actual kilogram body weight (g/kgBW/d). Diet quality was assessed using the 2013 Dietary Guidelines Index, and obesity measures included Body Mass Index (BMI) and waist circumference (WC). Sex-stratified multiple linear and logistic regressions were performed and adjusted for potential confounders. Total protein (g/d) was directly associated with diet quality (males, β = 0.15 (95% CI 0.12, 0.19); females, β = 0.25 (0.22, 0.29)), and this association was consistent across units. Protein intake (g/d) was directly associated with BMI (males, β = 0.07% (0.04%, 0.11%); females, β = 0.09% (0.04%, 0.15%)), and WC (males, β = 0.04 (0.01, 0.06); females, β = 0.05 (0.00, 0.09)). While in males, protein as %EI was associated with higher WC, no association was found in females. Adults with higher protein intake (g/d) had higher odds of overweight/obesity (males, OR = 1.01 (1.00, 1.01); females, OR = 1.01 (1.00, 1.01)), and central overweight/obesity (females, OR = 1.01 (1.00, 1.01)), but no significant association with females odds of overweight/obesity when protein was expressed in %EI. In conclusion, protein intake was positively associated with diet quality and obesity, yet these associations were stronger for women. The effect sizes also varied by measurement unit due to the different scales of those units.","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11428053/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142336931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Net microbial yield was negatively correlated with total gas at 8 h (P < 0•001), but not at 24 h (P = 0•052), and negatively correlated with CH4 production (P < 0•001). Higher initial inoculum microbial mass was related to a lower net microbial yield (P < 0•001) but a higher CH4 production (P < 0•001). A significant difference between grass silage and maize silage was detected within the context of these relationships (P < 0•050). The metabolic hydrogen (2H) recovery was 102.8 ± 12.3 % for grass silages and 118.8 ± 13.3% for maize silages. Overall, grass silages favoured more substrate conversion to microbial biomass and less to fermentation end products than maize silage. Lower inoculum microbial mass facilitated more microbial growth and, because of the 2H sink by microbial synthesis, decreased CH4 production.","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11428107/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142336948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A pretested guide was used to capture information regarding types of complementary food, lists of food items, and ingredients included in their complementary formulation. A thematic analysis for emerging points of discussion was carried out. Three major themes, including infant and young child feeding practices, food items included in complementary food, and their consumption frequencies, as well as the incorporation of climate-resilient crops into complementary foods as coping mechanisms, emerged. Breastfeeding was common and regarded as essential. Gruel and porridge from grains, roots, and tubers were regular parts of complementary foods in the study area. Moringa and sorghum were dominantly identified as climate-resilient crops regularly grown and used in complementary foods. Growing these crops was regarded as a coping strategy for drought and seasonal constraints. The district is one of the most drought-prone areas in Ethiopia, compromising the quality of complementary food. Unlike the World Health Organization recommendation, the grains, roots, and tubers-based diet formed the basis of complementary food lacking flesh foods, eggs, pulses, and other fruits and vegetables. Thus, it is recommended to improve complementary food quality through value-addition using locally accessible crops.","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11428050/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142336942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to develop maximum sodium reduction targets for New Zealand (NZ) fast foods and compare them with the current sodium content of products. Sodium content and serving size data were sourced from an existing database of major NZ fast-food chains. Target development followed a step-by-step process, informed by international targets and serving sizes, and previous methods for packaged supermarket foods. Sodium reduction targets were set per 100 g and serving, using a 40% reduction in the mean sodium content or the value met by 35-45% of products. Thirty-four per cent (1797/5246) of products in the database had sodium data available for target development. Sodium reduction targets were developed for 17 fast-food categories. Per 100 g targets ranged from 158 mg for 'Other salads' to 665 mg for 'Mayonnaise and dressings'. Per serving targets ranged from 118 mg for 'Sauce' to 1270 mg for 'Burgers with cured meat'. The largest difference between the current mean sodium content and corresponding target was for 'Other salads' and 'Grilled Chicken' (both -40% per 100g) and 'Fries and potato products' (-45% per serving), and the smallest, 'Pizza with cured meat toppings' (-3% per 100 g) and 'Pies, tarts, sausage rolls and quiches' (-4% per serving). The results indicate the display of nutrition information should be mandated and there is considerable room for sodium reduction in NZ fast foods.

Overall, median (IQR) folate, cobalamin, tHcy, and MMA concentrations were 47 (35-66) nmol/L, 250 (178-368) pmol/L, 6.99 (5.69-9.27) µmol/L, and 0.35 (0.24-0.83) µmol/L, respectively. None of the infants were folate deficient, 15% were vitamin B12 deficient (< 148 pmol/L), and 23% had low vitamin B12 status (148-221 pmol/L). Elevated tHcy (> 6.5 μmol/L) and MMA (> 0.26 μmol/L) were found in 62% and 69% of the infants, respectively. Compared to weaned, exclusively or partially breastfed infants were younger and had 46% higher tHcy concentrations (P < 0.001), in addition to 47% and 39% lower cobalamin concentrations (P < 0.001), respectively. However, the observed biomarker concentrations appeared to be independent of infant age. In conclusion, low vitamin B12 status was prevalent and appeared to be more common in the younger exclusively breastfed compared to older weaned infants. The implications of low vitamin B12 status in infancy are unknown and require further investigation.","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11428113/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142336941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
