We hypothesised that antioxidant supplementation during 60 days of 6° head-down tilt bed rest (HDBR), an analogue of spaceflight, would have a protective effect on bone mineral density (BMD), content (BMC) and bone structure parameters. An exploratory, randomised, controlled, single-blind intervention trial was conducted in a parallel design with 20 healthy male volunteers (age 34 ± 8 y, weight 74 ± 6 kg). The study included 14 days of baseline data collection (BDC) before bed rest, followed by 60 days of HDBR and a 14-day recovery period. Ten subjects in the antioxidant group received a supplement (741 mg/d polyphenols, 2.1 g/d omega-3 fatty acids, 168 mg/d vitamin E and 80 μg/d selenium) daily. Ten subjects in the control group received no supplement. The diet was consistent with dietary reference intakes, individually tailored based on the subject's bodyweight and strictly controlled. We measured whole-body, lumbar spine and femur BMD and BMC, as well as BMD of the cortical and trabecular compartments of the distal radius and tibia, and cortical and trabecular thickness during BDC, HDBR and recovery. Data were analysed using linear mixed models. The supplementation of an antioxidant cocktail did not mitigate the deteriorating effects of HDBR on BMD, BMC and bone structure parameters.

However, assessing the impact of such a dietary shift on the dietary and nutritional intake of traditionally omnivorous populations is needed. The objective of this study was to assess the impact of substituting a traditional omnivorous-based lunch for a vegetarian, legume-based meal on the daily dietary and nutritional intake in a group of omnivorous adults in the city of Porto, Portugal. Nineteen, non-vegetarian, healthy young adults consumed a vegetarian, legume-based meal from Monday to Friday, for 8 consecutive weeks. Socio-demographic data, health status, lifestyle-related information and anthropometric parameters were recorded. Three-day food records were used to collect food intake at baseline and week 8. European Food Safety Authority and World Health Organization reference values were used to assess nutritional inadequacies. Variables were described as medians (P₂₅ and P₇₅ ). Wilcoxon signed-rank and Mann-Whitney tests were used for statistical comparisons. A p-value of <0.05 was considered statistically significant. Participants consumed 38.0 (P₂₅  = 35.0; P₇₅  = 40.0) meals, resulting in an intake of 84.5 g (P₂₅  = 74.9; P₇₅  = 98.4) of cooked legumes per meal, meaning 11 subjects (57.9%) met the Portuguese guidelines for legume consumption (≥80 g/day of legumes). The current dietary intervention did not seem to aggravate the prevalence of nutritional inadequacies for the macro- and micronutrients tested, except for the case of vitamin B₁₂ (52.6% [95% CI: 28.9-75.6] vs. 78.9% [95% CI: 54.4-94.0]). This could be linked to the reduction of dietary sources of this vitamin which is an expected consequence of vegetarian meals. Dietary changes towards grain legume-based diets are desirable yet need to be carefully implemented to prevent exacerbating potential nutrient inadequacies, especially of vitamin B₁₂ .</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":"48 2","pages":"190-202"},"PeriodicalIF":3.3,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9559866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The covariate-adjusted prevalence of anaemia in 2012 and 2018-2019 and the changes over that period were estimated from a multiple log-binomial regression model and the factors associated with anaemia were assessed in each survey year and in both years combined.

This pilot study, therefore, aimed to explore nutrient status, diet quality and cardiovascular and inflammatory responses in aerobically trained adult males following vegan and omnivorous dietary patterns during aerobic exercise. An incremental ramp running test was used to assess peak oxygen consumption (VO_2peak ) in males aged 18-55 years, engaging in >4 h training/week. Exercise testing was performed during walking and steady-state running conditions (60% and 90% of VO_2peak ). Participants were grouped by dietary pattern type and were equivalent for age, training volume and VO_2peak . When compared to the omnivorous group (n = 8, age 35.6 years, VO_2peak 55.7 mL/kg/min), the vegan group (n = 12, age 33.4 years, VO_2peak 56.4 m/kg/min) consumed more energy from carbohydrates (p = 0.007), and less energy from protein (p = 0.001) while exhibiting a higher overall diet quality score (p = 0.008). No differences in inflammatory biomarkers were observed before or after running. Total red blood cell count, haemoglobin and haematocrit levels were lower in the vegan dietary group. In summary, aerobically trained males, following a long-term vegan diet, can tolerate a short bout of running broadly comparatively to their omnivore counterparts. More arduous endurance exercise conditions should be explored to further uncover potential outcomes of consuming a vegan dietary pattern and exercise-related physiology.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":"48 2","pages":"227-242"},"PeriodicalIF":3.3,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9551365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this has been controversial amongst dietitians and nutritionists who work in commercial settings. Given the lack of empirical data, a survey was conducted amongst UK-based nutrition professionals to assess their knowledge of, and attitudes to, Article 12(c). The findings revealed confusion about the scope of the regulation and how it applies to working practices, with a considerable proportion of respondents being unable to recognise examples of commercial communications or health claims, indicating a need for additional training. There was also a broad interpretation of what nutrition professionals could, and could not, say about a hypothetical food product. This paper explores current guidance in Great Britain and debates the proportionality and fairness of Article 12(c), which, at present, does not regulate authorised health claims made by influencers or celebrities in commercial communications to consumers. It could be argued that consumers are better protected by the articulation of health claims by nutrition professionals who are guided by codes of practice rather than by unqualified, unregulated individuals. Hence, it is essential to level the regulatory playing field either by revising the NHCR to amend Article 12(c) or by updating the guidance to apply an interpretation of the Article's intention which enables a broader role for nutrition professionals in commercial communications. Such action would also be consistent with the UK's better regulation agenda to ensure evidence-based, proportionate regulation for industry.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":"48 2","pages":"216-226"},"PeriodicalIF":3.3,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9562908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A retrospective study was carried out in a medium-sized hospital in Brazil, with patients ≥20 years old admitted between July 2017 and December 2019. Patients who were overweight and had records of Nutritional Risk Screening-2002 (NRS-2002) and Mini-Nutritional Assessment-Short Form (MNA-SF) in their medical files were included in the study. Clinical outcomes data (longer length of stay, readmission during the study period and mortality before the end of study or during hospitalisation) were obtained.

This systematic review was guided by the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) and Synthesis Without Meta-Analysis (SWiM) and conducted vote counting of studies based on the direction of effect.
