Introduction: Preventing chronic diseases among children and adolescents requires a comprehensive approach. The Nutri-Score, a front-of-pack nutrition labeling system, may play an important role in public health by enhancing overall nutritional quality of dietary intake, a key modifiable risk factor. The aim of this study was to investigate the ability of the 2015 and 2023 NS-NPM to discriminate food consumption and nutrient intake in a population of French children and adolescents.

Background: Mindful eating (ME) is a promising approach for promoting healthy eating. Although an association between ME and healthier eating habits has been indicated in the literature, data remain limited. The aim of this cross-sectional study was to investigate the association between ME and several nutritional indicators, including overall diet quality, consumption of ultra-processed foods (UPF), organic foods, food groups, and intake of energy and nutrients in a large population sample.

Article Synopsis
  • * A study of 159 farms across six European countries showed that the diversity and traits of ground beetles affect their role in pest control and crop yields, with smaller, mobile beetles being more effective in aphid removal.
  • * Results highlighted that while maintaining functional diversity of ground beetles helps with pest management, it doesn't necessarily lead to higher crop yields, emphasizing that reduced land management intensity supports beneficial beetle populations.

The potential of the EAT-Lancet reference diet, which promotes a healthy diet within planetary limits, to reduce greenhouse gas emissions (GHGe) remains understudied. This study examines the role of nutritional and acceptability constraints in reducing GHGe through diet optimization, and tests the alignment between GHGe reduction and the EAT-Lancet score. The study used data from 29,413 NutriNet-Santé participants to model French diets and evaluate their environmental, nutritional, economic, and health impact.

Diets, but also overall food environments, comprise a variety of significant factors with direct and indirect impacts on human health. Eco-Regions are geographical areas with a territorial approach to rural development, utilizing organic food and farming practices, and principles and promoting sustainable communities and food systems. However, so far, little attention has been given to quantifying aspects of the health of citizens living in these sustainable transition territories.

Background: Higher education students are an important target group for public health nutrition interventions. When designing tailored and contextually relevant interventions, participatory and co-creation approaches are increasingly recognized as promising but their use and effectiveness has not been assessed in this type of population. We systematically reviewed interventions aiming to improve dietary quality and/or food security in higher education settings with the aims 1) to identify and describe their participatory and co-creation approaches and 2) to compare the effectiveness of interventions using or not using participatory and co-creation approaches.

Article Synopsis
  • The study aimed to investigate how insomnia and anxiety together (comorbidity) relate to the risk of developing type 2 diabetes (T2D) among a large group of adults without diabetes at the start.
  • Researchers analyzed data from 35,014 participants in the French NutriNet-Santé cohort and found that while anxiety and insomnia alone didn't significantly increase T2D risk, those with both conditions had a 40% higher risk of developing T2D over a 5.9-year follow-up.
  • The results suggest that having both anxiety and insomnia could be a key factor in the onset of T2D, highlighting the need for more research to explore these findings further and inform diabetes prevention strategies.

Background: Some research shows that advertising for high-fat, sugar, or salt (HFSS) products is contributing to a shift in consumer preferences toward products of poor nutritional quality, leading to unhealthy nutritional intakes that increase the risk of obesity and chronic diseases. A strategy of displaying simple and understandable nutritional information (like the front-of-pack nutrition label Nutri-Score) in food messages could be an aid to help guide consumers' choice towards healthier products.

Methods: A randomized controlled experiment was conducted on 27,085 participants randomly assigned to two experimental conditions or a control condition.

Background: Emulsifiers are widely used food additives in industrially processed foods to improve texture and enhance shelf-life. Experimental research suggests deleterious effects of emulsifiers on the intestinal microbiota and the metabolome, leading to chronic inflammation and increasing susceptibility to carcinogenesis. However, human epidemiological evidence investigating their association with cancer is nonexistent.
