Background/aim: Building on the evidence for multifaceted effects of different nutrients, foods and dietary patterns is a new priority for nutrition science. This review aims to describe the causal pathways and biological mechanisms that elucidate the associations between different nutrition exposures (nutrients, foods and dietary patterns) and health outcomes.
Methods: A scoping review was conducted in two stages: 1) review of nutrition science textbooks; and 2) a review of reviews of empirical literature using a systematic approach to elucidate causal pathways and biological mechanisms for nutrition exposures and health outcomes.
Objective: This study develops successful ageing profiles across six low- and middle-income countries (LMIC) and examines associations with fruit and vegetable (F&V) intake.
Design: A cross-sectional analysis was conducted in mid-aged and older adults from the WHO Study of Global Ageing. Participants without chronic disease, cognitive impairment, depression or disability and with good physical, cardiovascular and respiratory function were considered to have successfully aged.
Understanding eating behaviours of young adults is crucial for developing strategies to improve their diet quality. Factors that influence eating behaviours are often multifaceted and highly contextual, with little research focused on young adults. This study examined contextual factors influencing food intake at eating occasions among young adults.

This study aimed to examine characteristics associated with fruit and vegetable consumption in Chinese men and women aged 50 years and over. Data from the first wave of the Chinese cohort (2008-2010) of the WHO's Study on global AGEing and adult health (SAGE) survey was used.

- Snacking is prevalent among adolescents, making up over 25% of their total energy intake, but its impact on diet quality is still not well understood.
- The study analyzed snack characteristics of 935 Australian adolescents using a 24-hour dietary recall, focusing on snack frequency, energy density (ED), and the types of snacks consumed in relation to their diet quality measured by the Dietary Guideline Index for Children and Adolescents (DGI-CA).
- Results indicated that while snack frequency remained consistent across different diet quality levels, adolescents with better diet quality had lower snack ED and a higher intake of healthy foods, while consuming fewer unhealthy discretionary snacks.
