Purpose: As healthy eating recommendations shift to incorporate environmentally sustainable eating principles, it becomes crucial to understand whether children's dietary intakes align with global recommendations such as the EAT-Lancet Commission Planetary Health Diet (PHD), in addition to national health-promoting guidelines, including the Australian Dietary Guidelines (ADG). This cross-sectional study aimed to assess the alignment of young Australian children's food intakes with these recommendations.
Methods: Dietary data from the 2011-2012 National Nutrition and Physical Activity Survey for children aged 2-8 years were used and compared with, energy-adjusted target amounts of the PHD and ADG Foundation Diet.
Article Synopsis
- The study investigates how different types of senescent cells in the skin contribute to the development of cancer in patients with Familial Melanoma Syndrome (FMS), who have defects in the CDKN2A gene.
- Melanocytes from FMS patients show lower p16 levels and higher DNA damage markers compared to fibroblasts, while patient fibroblasts also exhibit unusual behaviors, such as increased replicative capacity and defective senescence.
- The findings suggest that the combination of DNA damage in melanocytes and impaired senescence in fibroblasts may weaken the immune response and enhance the risk of melanoma in these patients.
Article Synopsis
- 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.
Child eating behaviour traits are associated with several aspects of dietary intake of pre-school children, however the associations between child eating behaviour traits and overall dietary quality in pre-school children has not been examined. Additionally, it is unknown how these relationships vary by age. This study examines the associations between child eating behaviour traits and pre-school children's dietary quality and whether children's age moderates these associations.
