Growing evidence suggests that diets high in ultra-processed foods (UPFs) are harming human and planetary health. UPFs therefore pose a complex regulatory challenge, yet, to date, little research has systematically assessed how governments have responded to UPFs in national food policies. Here we analyse data from the NOURISHING database to assess the scope and strength of UPF-related regulatory interventions worldwide, using three frameworks-namely, NOURISHING, the Nuffield Ladder and the Modalities of Control framework. Of the 417 UPF-related measures identified, most imply food processing or mention UPF examples rather than refer to processing or UPFs specifically. The scope of action is narrow; 85.9% of interventions change the food environment, largely represented by nutrition labelling. The strength of action is limited; interventions are skewed towards informational measures to influence consumer choice, and 47.1% of measures use consensus to shape food business conduct. These findings highlight an opportunity to broaden the scope and strength of UPF-related regulation.

Exploring Dietary- and Disease-Related Influences on Flatulence and Fecal Odor Perception in Inflammatory Bowel Disease.
J Clin Med
December 2024
Department of Gastroenterology, Hepatology, Infectious Diseases and Endocrinology, Hannover Medical School, 30625 Hannover, Germany.
: Inflammatory bowel disease (IBD) affects gastrointestinal function and may alter fecal and flatulence odor (intestinal odor) due to changes in inflammation, the gut microbiome, and metabolism. Investigating the relationship between dietary habits and intestinal odor in IBD is critical given the relationship between diet, gut health, and microbiome diversity. : We performed a cohort analysis of a monocentric, cross-sectional study at a tertiary referral center and compared the perception of fecal and flatulence odor in 233 IBD patients (n = 117 women) with that of 96 healthy controls (HCs) (n = 67 women).

Methods: Using a stratified cluster random sampling method, 3-7-year-old children from 18 kindergartens across Wuxi were selected as the survey subjects. An online survey was conducted to collect demographic information about children and their parents, dietary information, lifestyle data, and family backgrounds.
Reducing Agricultural Land Use Through Plant-Based Diets: A Case Study of Romania.
Nutrients
January 2025
University of Life Sciences "King Mihai I", 300645 Timisoara, Romania.
Background/objectives: Agricultural systems face increasing global pressure to address sustainability challenges, particularly regarding land use and environmental protection. In Romania, where traditional diets are heavily dependent on animal-based products, optimizing land use is critical. This study investigates the potential of plant-based diets to reduce agricultural land use, examining scenarios of partial and complete replacement of animal protein with plant protein sources (soy, peas, and potatoes).

Nutrients
January 2025
Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs, Beijing 100081, China.
Background: It is common for consumers to purchase ultra-processed foods that are perceived to have health risks, and this phenomenon is rarely explained in the existing literature from the perspective of consumers' responses to the intuitive marketing of flavor labels and the packaging.
Methods: This study aimed to fill this knowledge gap and investigated the attention of 920 participants aged 18~59 across China toward fat and sodium content information for six ultra-processed foods (pastry foods, quick-frozen foods, dessert foods, puffed foods, beverages, and sauces) presented in nutrition facts tables based on the theoretical analysis framework for purchasing decisions on ultra-processed foods by using the binary logit model.
Results: It was found that the respondent' s attention to fat and sodium content information was positively influenced by health risk perception levels and levels of knowledge about fat and sodium but negatively influenced by the interaction term between flavor labels (or the packaging) that stimulated the purchase desire and health risk perception levels (or levels of knowledge about fat and sodium).
Comparative Nutritional Profile of Publicly Procured Foods for School Meals in Federal Schools in Northeastern Brazil Pre- and Post-COVID-19 Pandemic.
Nutrients
December 2024
Post-Graduation Program in Nutrition, Federal University of Rio Grande do Norte, Natal 59078-900, RN, Brazil.
Unlabelled: School meals play a critical role in supporting students' biopsychosocial growth, development, learning, academic performance, and the establishment of healthy eating habits. In public institutions, food procurement is conducted through formal public procurement processes. However, emphasizing cost-effectiveness in bidding criteria, such as prioritizing the lowest product price, may inadvertently encourage the acquisition of foods high in critical nutrients.
