The beneficial effects of a Mediterranean diet are due to the numerous active compounds in the food and, particularly, the high concentration of compounds with synergistically acting antioxidant properties. Resveratrol, a stilbenoid nonflavonoid phenol, is an antioxidant that is naturally produced by numerous plants as a defensive agent in response to attacks from pathogens, such as bacteria and fungi. Resveratrol has several effects on human health, including on the lipid profile, where it primarily downregulates the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase, reducing the synthesis of cholesterol. Resveratrol also increases the expression of LDL receptors in the liver, contributing to the reduction in the LDL-cholesterol levels. This short narrative review, based on relevant articles written in English from a PubMed search, using the keywords “resveratrol”, “atherosclerosis”, “cardiovascular disease”, and “Mediterranean Diet“, focuses on the possible effects of this molecule on cardiovascular disease, lipid metabolism, and atherosclerosis.

Being overweight or obese is a public health problem. This work evaluated a food and nutrition education (FNE) intervention to reduce overweight status among schoolchildren in four schools in the West Panama Province. This was a quasi-experimental before-and-after study that implemented a 34-week FNE intervention through workshops with didactic material to 403 children between 8 and 13 years old. A knowledge and attitude survey was used as an evaluation tool before and after the FNE intervention. The prevalence of excess weight (40%) did not reduce after the intervention. The zBMI at the beginning was 0.57 (1.29) for girls and 0.70 (1.36) for boys, and at the final evaluation was 0.57 (1.28) for girls and 0.67 (1.33) for boys. No significant differences were observed between the point of evaluation and sex. No differences were reported in the median level of attitude, although higher levels of knowledge were reported in students of both sexes. The FNE in schoolchildren can be effective in acquiring knowledge and maintaining a positive attitude towards food, but more research is needed to address nutritional status. Although the intervention had no impact on nutritional status, the FNE facilitated the adoption of skills and competencies in schoolchildren. The success of the implementation of the study highlighted the feasibility of replicating the FNE interventions on a larger scale to contribute positively to the multi-level and sectoral public policy Study Without Hunger in Panama.

Recent evidence suggests a link between Inflammatory Bowel Disease (IBD) and eating disorders, an emerging complex bidirectional association. Indeed, the overlap of symptoms and signs can lead to delayed diagnosis and misdiagnosis of both conditions, but also the fear of food-induced symptoms, commonly observed in patients with IBD, determines dietary restrictions which in predisposed individuals may induce an overt eating disorder. ARFID (Avoidant Restrictive Food Intake Disorder) and anorexia nervosa are the eating disorders more frequently reported, while disordered eating and orthorexia nervosa are emerging conditions. Disease worsening due to refusal of therapies in patients with anorexia is also a matter of concern and an increased awareness of the possible association of these conditions by gastroenterologists and dietitians is strongly warranted in order for patients to receive the appropriate counseling.

Sleep quality (duration, efficiency, and latency) is directly associated with human health. An interventional study reported that the time of dinner influenced sleep latency, suggesting that it may also be associated with other sleep quality indices under free-living conditions. Therefore, we cross-sectionally examined the association between the time from dinner to bedtime (TDB) and sleep quality indices under free-living conditions in the young Japanese population. Based on the TDB, 264 participants were separated into three quantiles (T1, ≤3.79 h; T2, 3.80–4.94 h; T3, ≥4.95 h from dinner to bedtime). The T1 (mean ± standard error; 26.4 ± 2.2 min, p = 0.081) and T2 groups (30.8 ± 2.2 min, p = 0.001) showed longer sleep latency compared to the T3 group (19.6 ± 2.2 min), after adjusting for confounding factors. Sleep efficiency in the T1 group (77.5 ± 1.6%) tended to be greater than in the T3 group (72.1 ± 1.6%, p = 0.061), whereas sleep efficiency in the T2 group was not significantly different (77.0 ± 1.6%) from that in the T1 group. Therefore, shortened TDB was associated with prolonged sleep latency in free-living conditions. Meal timing, especially dinner, should be considered along with other sleep hygiene measures to improve human health.
睡眠质量(持续时间、效率和潜伏期)与人体健康直接相关。一项介入性研究报告说，晚餐的时间影响睡眠潜伏期，这表明它也可能与自由生活条件下的其他睡眠质量指标有关。因此，我们横断面研究了日本年轻人在自由生活条件下从晚餐到就寝时间(TDB)与睡眠质量指数之间的关系。根据TDB将264名参与者分为三个分位数(T1，≤3.79 h;T2, 3.80-4.94 h;T3，从晚餐到就寝时间≥4.95 h)。T1(平均值±标准误差;校正混杂因素后，T2组(30.8±2.2 min, p = 0.001)和T2组(26.4±2.2 min, p = 0.081)的睡眠潜伏期明显长于T3组(19.6±2.2 min)。T1组睡眠效率(77.5±1.6%)高于T3组(72.1±1.6%，p = 0.061)，而T2组睡眠效率与T1组无显著差异(77.0±1.6%)。因此，在自由生活条件下，TDB缩短与睡眠潜伏期延长有关。用餐时间，尤其是晚餐，应该与其他睡眠卫生措施一起考虑，以改善人类健康。

Cancer survivors consider nutrition to be highly important and are motivated to seek information about lifestyle changes, including nutrition, to improve their long-term health. Despite this, suboptimal dietary intake is still reported. Understanding cancer-specific barriers and facilitators to healthy eating among this population could help develop targeted interventions for this group. This study explored the barriers and facilitators to following a healthy diet among cancer survivors using the Theoretical Domains Framework (TDF) and COM-B model. Semi-structured focus groups with 20 cancer survivors were conducted between February and August 2021, which were transcribed verbatim. Seven key TDF domains accounted for 87% of all coded responses. These were (a) environmental context and resources; (b) knowledge; (c) behavioural regulation; (d) social/professional role and identity; (e) belief about consequences; (f) social influences; and (g) skills. Key barriers were lack of knowledge, non-specific or irrelevant information, environmental aspects, and family. Facilitators were awareness of the importance of nutrition, the health benefits of a plant-based diet, confidence in cooking skills, organisation, balance, family, time, and viewing themselves as someone who eats healthily and access to fresh produce. Enablement was the most prominently linked intervention function. This work can inform future interventions in this area and ensure they are end-user-centred.

Background: Climate change is a serious threat to human wellbeing and development. Global reduction of meat intake is key to addressing climate change and other modern sustainability challenges. Plant-based and mycoprotein-based meat substitutes are predicted to play a key role in the reduction of meat intake; however, their impact on human health is unclear. The main objective of this meta-analysis was to assess the short-term effects of meat substitutes on important cardiometabolic biomarkers (total cholesterol, TC; LDL-cholesterol, LDL-C; HDL-cholesterol, HDL-C; triglycerides, TG; systolic blood pressure, SBP; diastolic blood pressure, DBP; fasting blood glucose, FBG; weight) in controlled clinical trials. Methods: Embase and MEDLINE were searched to identify controlled clinical trials with meat substitute interventions and cardiometabolic biomarker outcomes. Standardised mean differences in TC, LDL-C, HDL-C, TG, FBG, SBP, DBP, and weight and 95% confidence intervals were pooled using a random effects model. Risk of bias, heterogeneity, sensitivity, and publication bias were assessed. Of the 934 records identified, 12 studies met the inclusion criteria. In the pooled analyses, the consumption of meat substitutes was associated with significantly lower TC (−0.50 mmol/L [95% CIs −0.70, −0.29]), LDL-C (−0.39 mmol/L [−0.57, −0.21]), and TG (−0.15 mmol/L [−0.29, −0.01]), non-significantly lower FBG (−0.08 [−0.23, 0.08]), SBP (−0.32 [−1.79, 1.41]), and weight (−0.12 [−1.52, 1.27]), and non-significantly higher HDL-C (0.01 [−0.02, 0.05]) and DBP (0.49 [−0.30, 1.28]). There was evidence of publication bias, and some heterogeneity was detected. The certainty of evidence was moderate for the TC and HDL-C results, low for the LDL-C, TG, SBP, DBP, and weight results, and very low for the FBG results. Conclusions: Replacement of some or all meat with plant-based or mycoprotein-based substitutes may lower TC, LDL-C, and TG.

Anxiety disorder is characterized by excessive fear or avoidance of perceived threats that can be persistent and debilitating. Diet is a modifiable risk factor that may contribute to the pathogenesis or treatment of anxiety, depending on diet quality. Although the biological mechanisms by which food, specific nutrients, and nutraceuticals impact mental health are not completely understood, implicated pathways include inflammation, oxidative stress, brain plasticity effects, mitochondrial dysfunction, and neurotransmitter metabolism. Essential dietary trace minerals such as zinc, copper, iron, and selenium are critical components for numerous biological proteins and may have a role in these proposed mechanisms related to brain health and anxiety. This narrative review examines the influence of essential trace elements zinc, copper, iron, and selenium on anxiety symptoms based on the latest peer-reviewed scientific evidence. Current research indicates that deficiencies in zinc, iron, and selenium are associated with anxiety, while copper overload may impact anxiety to a greater degree than copper deficiency. Further investigation is needed to understand the specific neurobiological mechanisms involved. Overall, the collective findings demonstrate the importance of optimizing trace mineral homeostasis for the mitigation of anxiety disorders and preservation of mental health.

Supervised practice is a prerequisite to becoming a registered dietitian. Research suggests that environmental and social factors may affect dietary choices. This focus group research aimed to gather opinions from dietetic interns to understand what factors related to supervised practice, if any, affected their dietary habits. Qualitative data were collected via seven recorded virtual focus groups in which trained moderators facilitated a discussion using a series of controlled questions. Participants, dietetic interns (n = 42) who were currently completing or had completed their supervised practice within the previous six months, attended one of seven virtual focus groups. Each focus group had five to eight participants. Transcripts were separately coded by two trained researchers using a grounded theory approach to identify themes and subthemes. Researchers discussed any disagreements in coding and established a consensus. Elements related to the dietetic internship were observed to influence participants’ dietary choices. Main themes included time, finances, food access and availability, physical and mental effects, non-supervised practice factors, and social factors. Dietetic programs and preceptors should explore ways to raise interns’ awareness and minimize the potential negative impacts of these factors on interns’ dietary habits to improve their overall internship experience.

The aim of this survey was to identify, (1) use of Dietitians Australia best practice guidelines, (2) contemporary practices/knowledge, and (3) professional development needs of Australian dietitians in relation to management of clients with overweight or obesity. A cross-sectional online survey consisting of 67 multiple choice and Likert scale questions on the three survey aims was administered. Data were collected between 2020–2021 and reported descriptively as frequency (%). Of 178 survey attempts, 80 respondents completed all questions (45%). Most respondents spent >50% of their time working with individuals with overweight/obesity, usually in private practice (47%). Two thirds of respondents had accessed best practice guidelines, but only 12% had completely read best practice guidelines. General healthy eating was the most frequent dietary approach used (77%). Seventy-five percent (n = 56) of dietitians reported that dietary interventions were selected based on client preference. Almost half of dietitians rated their knowledge and level of skill in management of obesity as good. Approximately 60% (n = 41) dietitians reported their skill gap was related to providing behavioural therapy/counselling. Results of the current survey indicate that use of best practice guidelines is low. However, dietitians surveyed reported that they had a good understanding of obesity management and choose a client centred approach to management, which is in line with current recommendations. Professional development activities, particularly regarding behavioural counselling are of particular interest to dietitians working with individuals with obesity.
