Healthcare organisations in the United Kingdom must comply with national standards for food and drink, including sustainable sourcing and minimisation, mitigation, and management of food waste. Despite this, an estimated one in six plates of food served in hospitals are wasted daily, producing 12% of the UK’s food waste, equating to 6% of carbon dioxide emissions (CO2e) nationally, and a waste-management cost of GBP 230 m per annum. Within healthcare, there is a move towards the implementation of “plant-based diets by default” to reduce the environmental impact, improve nutritional outcomes, and reduce costs. However, plant-based diets are often perceived as being difficult to prepare by caterers, less enjoyable, and potentially resulting in more food waste. We conducted a scoping review to examine the influence of the social, medical, and physical environment on food intake during inpatient admission to a mental health hospital. Fourteen studies were included. We identified five critical knowledge areas: (i) food and socio-cultural environment, (ii) evidence-based measures and strategies to reduce food waste, (iii) economic food environment, (iv) inevitability of weight gain, and (v) applications of theoretical models for behaviour change. Future research should explore the development of a behaviour-change framework inclusive of training, education, and goal-setting components for staff, patients, and visitors. Full article

The national food consumption surveys are crucial for monitoring the nutritional status of population but are also time and resource consuming. The growing use of technology and web-based platforms can help to reduce the logistical burden and cost of conventional methods. This study aims to compare self-administered 24 h recall to those obtained from interviewer-led 24 h recall by examining food items, food group and nutrient intakes using the online software FOODCONS 1.0 in both cases. The volunteers (39 adults) were randomized in A and B groups. On study days, they completed a self-administered 24 h recall and 3 h later, an interviewer-led 24 h recall. After 15 days, the same process was repeated in the opposite way. The difference in the two-day mean of energy and macro- and micronutrients intakes between the two methods was not statistically significant. The Bland–Altman analysis found a good agreement for energy, carbohydrates and fiber. At the level of food groups, the correlation coefficients indicated good concordance between the two methods. The self-administered 24 h recall through FOODCONS 1.0 software could be a suitable alternative to an interviewer-led interview, allowing a higher participation rate and less time-consuming food consumption studies.

This study aimed to provide an overview of published studies that assess the relationship between nutrition knowledge and dietary intake among university students. A scoping review was undertaken and articles assessing the relationship between nutrition knowledge and dietary intake among university students were identified. EMBASE, PsycINFO and Scopus were searched for peer-reviewed articles reporting primary research. The initial search generated 805 potentially relevant articles. After reviewing titles and abstracts and applying the exclusion criteria, 22 articles were deemed eligible for inclusion. Nutrition knowledge was measured in all studies and information was predominantly collected using adapted General Nutrition Knowledge Questionnaires (GNKQs). Dietary intake measurement methods varied across the studies, with the Food Frequency Questionnaire (FFQ) being commonly used. Findings identified that in most studies a positive relationship was found between nutrition knowledge and dietary intake. The ability to draw strong conclusions about the relationship between nutrition knowledge and dietary intake in university students is limited by the heterogeneity of the study design, the subpopulations considered, and the tools used. Notwithstanding this, findings indicate that the majority of studies reported a positive relationship between nutrition knowledge and dietary intake. Future studies should consider the use of validated assessment tools for both nutrition knowledge and dietary intake and the inclusion of more male student participants. Full article

Introduction: This is a secondary cross-sectional analysis of participants’ baseline data from the Baby-Act Trial to compare energy and macronutrients intake by feeding type. This was a cluster-randomized clinical trial among pregnant women and their infants participating in the Puerto Rico WIC program to test the clinical effectiveness of an intervention that addressed various infant obesity risk factors during the first year of life. Methods: Participants completed at baseline a sociodemographic questionnaire and a validated infant food frequency questionnaire (FFQ). The FFQ was analyzed for type of feeding (exclusively fed breastmilk, fed breastmilk and formula, or exclusively fed infant formula) and for energy and macronutrient intake (protein, carbohydrate, and fat). Analysis of covariance was used to compare intake type of feeding, adjusting for maternal age. race, education, number of previous children, gestational length, and pre-pregnancy BMI. Results: The present analysis included 368 mother–infant pairs. Mean age of mothers was 26.7 years and of infants 0.7 months. Ten infants fed complementary foods were removed from the analyses. A total of 39.9% of infants were exclusively breastmilk-fed, 47.2% were fed breastmilk and infant formula, and 12.8% were exclusively formula-fed (n = 358). Intake of energy, protein, fat, and carbohydrates was significantly lower in infants fed only breastmilk compared to infants fed a combination of breastmilk and infant formula, and intake of protein and carbohydrates were lower in infants fed a combination of breastmilk and infant formula compared to infants fed only infant formula, after adjusting for important confounders. Conclusions: Very early infant feeding practices are associated with differences in dietary intake. The long-term health implications of this findings need to be further studied. Full article

Essential amino acids and essential fatty acids are vital nutrients that must be obtained from the diet. However, traditional sources face limitations amid increasing global food security and sustainability challenges. This study aims to evaluate the nutritional potential of novel foods, including microalgae (e.g., spirulina and chlorella), fungi (e.g., oyster and shiitake mushrooms), edible insects (e.g., mealworms and migratory locusts), and unconventional plants (e.g., water lentils and canihua). The study will compare their amino acid and fatty acid profiles with those of conventional animal and plant sources. The comparative analysis conducted in this study reveals that these innovative foods offer balanced and high-quality protein and lipid profiles, and contribute essential nutrients needed to prevent deficiencies and support metabolic health. Significantly, the integration of these novel foods into established dietary patterns, such as the Mediterranean diet, has the potential to enhance nutritional quality while promoting environmental sustainability. In conclusion, the adoption of these innovative food sources provides a viable strategy to meet nutritional demands and address global health and ecological challenges, paving the way toward a more resilient and sustainable food system.

Athletic individuals may intentionally aim to gain weight, primarily as lean body mass, to improve athletic performance or to better match opponents’ size. This study aimed to investigate the self-reported nutrition- and exercise-related behaviors of athletic individuals aiming to gain weight. Cross-sectional data were drawn from an online survey of athletic adults recruited locally, nationally, and internationally. In total, 168 athletic participants (24 ± 5 years; 29% female, 71% male) completed the survey and were actively attempting or had attempted weight gain in the last 12 months to gain muscle mass (87.5%), for aesthetic reasons (66.1%), or to improve athletic performance (63.7%). The most prevalent dietary strategies reported to increase weight gain were consuming more energy than usual (88.0%) from mainly protein foods (83.9%) and using protein powders (67.3%). In total, 9.6% of participants reported using anabolic hormones. The main exercise change was increased resistance training (81.5%). Our results confirm that both male and female athletic individuals intentionally attempt to gain weight. Nutrition and exercise professionals may use the findings to be aware of these common dietary and exercise strategies and to better educate their athletic clients on appropriate methods that are evidence-based and not detrimental to health.

Climate change is a global priority requiring immediate action. A thorough understanding of the source of greenhouse gas emissions is essential to inform reduction strategies. This study aimed to quantify the climate footprint of two therapeutic diets—one diet for an adult with coeliac disease and one diet for an adult with type 2 diabetes—and then compare the climate footprint of these diets with the standard Australian diet and the Australian adapted EAT Lancet Planetary Health Diet. In addition, potential areas for reductions in greenhouse gas emissions were explored. All diets were developed for a 71-year-old male reference person. The amount of carbon dioxide produced by each diet was determined using the GWP* calculator for the reference person. Both the gluten-free and diabetic diet had a measurable climate footprint and were not considered climate-neutral. The diabetic diet produced 1.35 kg of carbon dioxide equivalents [CO2e] per day, and the gluten-free diet produced 2.51 kg of CO2e per day. Meat, dairy, and discretionary foods were the major contributors to the climate footprint of the two therapeutic diets. Substituting lamb for beef and soy milk for cow milk in the Australian context resulted in a 25% reduction in the climate footprint for the diabetic diet and 29% reduction for the gluten-free diet. Dietetic advice to reduce the climate footprint of therapeutic diets for coeliac disease and type 2 diabetes should focus on adapting diets to reduce animal-based products. Full article
