Special Issue Information

Dear Colleagues,

The determinants of healthy eating and nutrition are multifaceted and range from individual determinants, the social environment, the physical environment, and the economic environment. All these determinants are included in the interdisciplinary area of public health nutrition, which covers research, interventions, programs, practices, and policies to improve nutrition, nutritional status, or nutrition-related disease of populations. The individual factors include behavioral factors and characteristics that affect the choice of food, e.g., preferences, perceptions, nutritional knowledge, or psychological factors. The social and physical environment in which one lives includes the culture, family, or friends but also social media and all infrastructures that affect food availability, e.g., food outlets in the vicinity of work sites, schools, or home. Within the broader perspective is the economic environment, which includes prices of food, food security, or food marketing.

For this Special Issue on “Second Edition of Nutrition, Diets, and Public Health”, we are interested in original research, narrative reviews, systematic reviews, and meta-analyses concerning new evidence on the relationships between nutrition, diet, and health within a broad public health context. The topics we are interested in are broad, and we would be delighted to have highly up-to-date topics such as plant-based diets, food marketing, and ultra-processed foods included.

As the global trend of diabetes intensifies, the burden of vision-threatening retinopathy, particularly diabetic retinopathy (DR), is increasing. There is an urgent need to seek strategies for early prevention and control of DR. This study attempted to comprehensively evaluate the relationship between dietary nutrient intake and the risk of DR to provide assistance for doctors in guiding the diet of diabetic patients. Data from eligible participants with diabetes from the US National Health and Nutrition Examination Survey (NHANES) from 2003–2018 were analyzed. Univariate logistic regression was used to assess the association between 58 dietary nutrient intakes and self-reported eye disease risk. Multivariate logistic regression model was used to further evaluate the relationship between the two groups after adjusting relevant confounding factors. A total of 4595 diabetic patients were included. People with self-reported eye affliction/retinopathy had lower dietary fiber, butanoic, octanoic, vitamin A, alpha-carotene, folate, magnesium, copper and caffeine intake compared to those without self-reported eye affliction/retinopathy. The pooled ORs (95% CIs) were 0.78 (0.62–0.98), 0.79 (0.63–0.99), 0.72 (0.58–0.91), 0.74 (0.59–0.93), 0.70 (0.55–0.88), 075 (0.60–0.95), 0.79 (0.64–0.99), 0.67 (0.54–0.84) and 0.80 (0.64–0.99). Dietary cholesterol and hexadecenoic intake were higher, with the pooled ORs (95% CIs) of 1.26 (1.01–1.58) and 1.27 (1.02–1.59), respectively. Our research found that among dietary nutrients, dietary fiber, butanoic, octanoic, vitamin A, alpha-carotene, folate, magnesium, copper and caffeine intake reduced the occurrence of DR. Cholesterol and hexadecenoic intake promoted the occurrence of DR. This suggests that certain dietary nutrients should be paid more attention in the prevention of DR. Full article

Overweight and obesity are a cause of many non-communicable diseases leading to an increased risk of death. There are many programs aimed at weight reduction, but few publications have evaluated their effectiveness according to the gender and age of the subjects. The purpose of this study is to evaluate the effects of age and gender on weight loss outcomes in subjects participating in a 12-month online weight loss program. 400 subjects, 190 men and 210 women, were included in the study. The online intervention consisted of a 15% energy deficit diet and training (RESPO method). Changes in body weight over 12 months were similar (p = 0.14) across age groups. Weight reductions by month were statistically significant (p = 0.0001) in both groups. We noted no differences in weight loss between men and women expressed in kilograms. However, women reduced their body weight to a greater extent, i.e., by 2.7 percentage points, than men. Gender is a factor that may influence the effectiveness of weight loss programs, while age demonstrates no such influence. Our study shows that significant weight reduction during weight loss therapy is achieved by both men and women, but women can expect better results. Full article

An unhealthy diet is a major risk factor for chronic diseases. Although nutrition education and cooking demonstrations have resulted in favourable dietary changes, it is unclear whether this is sustainable for longer periods. This study aims to evaluate the long-term impact of a nutrition-led cooking intervention using the culinary education approach on dietary patterns based on My Healthy Plate (MHP). This was a quasi-experimental study involving patients who sought public primary care services in two polyclinics (mean age 59.3 years old). A self-administered survey was done at baseline, 6 months, and 1 year for both the intervention and the comparison groups. Participants in the intervention group were exposed to the health corner, which provided nutrition education and cooking demonstrations using the culinary education approach. A total of 216 participants completed the study at 1 year with a follow-up rate of 86%. Adjusted risk ratios (aRR) were obtained from negative binomial regression. Compared with the comparison group, participants in the intervention group were more likely to report adhering to the requirements of MHP at 6 months (aRR 1.83, 95% CI 1.12–2.99) and 1 year (aRR 1.54, 95% CI 1.10–2.16). Participants in the intervention group were less likely to add salt or sauces to food at 6 months (aRR 0.29, 95% CI 0.12–0.75) and 1 year (aRR 0.21, 95% CI 0.07–0.61) and more likely to remove fat when eating meat at 1 year (aRR 0.30, 95% CI 0.13–0.67) than the comparison group. The interventions at the health corner had a positive impact in helping patients achieve MHP recommendations, not adding salt and sauces to their food, and removing animal fat before eating. There is potential for expanding this initiative to improve healthy eating practices in other polyclinics. Full article

The promotion of nutritionally poor food and beverages (F&B) has a proven effect on children’s eating preferences and, therefore, plays a significant role in today’s childhood obesity epidemic. This study’s objective was to assess the prevalence (exposure) and context (power) of the F&B cues in influencer content across three platforms: TikTok, YouTube, and Instagram. The selected influencers were popular with adolescents, with a combined total of more than 34 million followers/subscribers. We employed the YouTube Influencer Marketing Protocol from the World Health Organization (WHO) as our basis for coding. We analysed a total of 360 videos/posts and, of these, 24% contained F&B cues, which is equivalent to 18.1 F&B cues/hour. In total, 77% of the cues were not permitted for children’s advertising, according to WHO criteria, and this was stable across all platforms, with chocolate and sugary confectionery (23%) as the most frequently featured products. Not-permitted F&B had a four-times higher chance of being branded, a five-times higher chance of being described positively, and received significantly more ‘likes’. In 62% of the analysed presentations, the branded product was mentioned, yet only 6% of the content was labelled as advertising. The present analysis delivers further grounds for discussion for policies and regulations of influencer marketing. Full article

Portion sizes of many energy-dense and nutrient-poor foods and drinks have increased in the past decade, whereas our understanding of the pattern of changes in package sizes remains limited. This study aimed to determine changing trends in sales and package sizes of savoury snacks in Australia, the USA, Japan and Hong Kong, and to investigate industry perspectives for these changes. Sales data (units per capita) between 2006–2020 on savoury snacks were extracted from the Euromonitor International database. Industry perspectives on package size changes were extracted systematically from selected databases, company reports and related websites following the PRISMA-ScR guidelines. The findings showed that sales per capita of savoury snacks of all package sizes increased across all four countries/regions between 2006–2020. Although changes in the proportion of smaller (<100 g) versus larger (>100 g) package size sales in each country/region over time were modest, Japan and Hong Kong exhibited a consistently higher proportion of smaller package sales compared with Australia and the USA (83.3%, 64.4%, 44.3%, 20.2%, respectively). Industry perspectives showed that increasing consumer health consciousness, demands for convenience and portion control were the main contributors to decreasing package sizes of savoury snacks. Industry reports from 2020 showed an increase in larger package size sales due to consumer purchasing behaviour amidst the COVID-19 pandemic. Full article
