The snack food potato chips induces food intake in ad libitum fed rats, which is associated with modulation of the brain reward system and other circuits. Here, we show that food intake in satiated rats is triggered by an optimal fat/carbohydrate ratio. Like potato chips, an isocaloric fat/carbohydrate mixture influenced whole brain activity pattern of rats, affecting circuits related e.g. to reward/addiction, but the number of modulated areas and the extent of modulation was lower compared to the snack food itself.

Background: The newly coined term Metabolic dysfunction-associated steatotic liver disease (MASLD) emphasizes the critical role of metabolic risk factors in the pathogenesis of fatty liver disease. The consumption of irregular breakfasts or late-night snacks has been identified as a factor closely associated with disruptions in the body's energy homeostasis and metabolic balance. However, the relationship between these behaviors and MASLD has not been previously examined.

Trajectories of Nutritional Quality, Diet-Related Environmental Impact, and Diet Cost in China: How Much Does Ultra-Processed Food and Drink Consumption Matter?
Nutrients
January 2025
Division of Human Nutrition and Health, Wageningen University & Research, 6700 AB Wageningen, The Netherlands.
Background: Rapid socio-economic developments confront China with a rising consumption of ultra-processed foods (UPFs) and ultra-processed drinks (UPDs). This study aims to evaluate their potential impact on diet transformation towards sustainability including nutrition, environmental sustainability, and diet-related cost.
Methods: Dietary intake was assessed by 24 h recalls in 27,311 participants (age: 40.

Department of Sports Rehabilitation, Jaeneung University, Incheon 22573, Republic of Korea.
Background/objectives: Adolescent obesity is highly likely to lead to adult obesity and is associated with dietary habits, subjective health, and body image perception. This study aimed to analyze the relationships between BMI, dietary habits, subjective health perception, and body image perception among Korean adolescents using data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 to explore strategies for reducing adolescent obesity rates.
Methods: Data from 50,427 participants were analyzed, including BMI, seven lifestyle factors (intake frequencies of water, milk, fruit, soft drinks, vegetables, breakfast, and late-night snacks), and responses to one item each for subjective health perception and body image perception.

HUM-613 Research Group, Department of Inorganic Chemistry, Faculty of Health Sciences, Melilla Campus, University of Granada, C/Santander s/n, 52005 Melilla, Spain.
(1) Background: The consumption of ultra-processed foods (UPFs) constitutes a public health problem given their high availability and easy accessibility among children and young people and their influence on the development of non-communicable diseases in the long term. In this context, culture and religion may be modulating factors for the consumption of processed food. The aim of this study is to assess the consumption of UPFs in Spanish schoolchildren living in Melilla (North Africa), together with the possible impact of religion on this.
