Introduction: Identifying the knowledge, attitudes, and practices (KAP) gaps of healthy eating can inform the design of effective interventions. This study aimed to test the validity and psychometric properties of a KAP of Healthy Eating Questionnaire (KAP-HEQ) tailored to the Chinese culture.
Methods: The dimensions and potential items of each KAP scale were identified from published KAP and health literacy questionnaires, which were supplemented by the findings of a previous qualitative healthy eating study. Content validity of the KAP-HEQ was evaluated by eight experts and eight Chinese parent-adolescent dyads in Hong Kong through content validity ratio (CVR), content validity index (CVI), and qualitative feedback. The feasibility, construct validity, reliability, and sensitivity of the KAP-HEQ were evaluated in this pilot study among 60 adolescent-parent dyads (120 persons) through an online survey. The first 30 dyads who completed the KAP-HEQ were invited to repeat the KAP-HEQ 2 weeks later to assess the test-retest reliability.
Results: The final 44-item KAP-HEQ was completed in 10-15 min by both adolescents and their adult parents. The CVR ranged from -0.38 to 1, and the CVI ranged from 0.56 to 1. Over 80% of the items achieved convergent validity (a significantly positive correlation with its hypothesized scale) and discriminant validity (a higher correlation with its hypothesized scale than with the other two scales). Cronbach's alpha for the internal consistency of the Overall, Attitude, and Practice scales was >0.7, while that of the Knowledge scale was 0.54. The intraclass correlation coefficient (ICC) on test-retest reliability of the Overall and individual scales were all >0.75 except that of the Knowledge scale (ICC = 0.58). The significant differences in KAP scale scores with small to large effect sizes were found between known groups as hypothesized, except the Attitude score between groups by household income, which supported the sensitivity of the KAP-HEQ.
Conclusion: The KAP-HEQ has shown good validity, reliability, and sensitivity among Chinese adolescents and adults, which can be applied to evaluate KAP status and gaps to inform the design and assess the effectiveness of healthy eating interventions.

Background: The Planetary Health Diet, proposed by the EAT-Lancet Commission, seeks to promote a sustainable and healthy diet for both humans and the environment. However, few studies have investigated relationships between the Planetary Health Diet and the genetic pathway of obesity. The aim of this study was to assess whether adherence to a Planetary Health Diet Index (PHDI) mediated or moderated the genetic susceptibility to obesity.

Background: Asian Indians are susceptible to developing type 2 diabetes at a lower age and often consume diets that are high in glycemic load and low in healthy fats.
Objectives: This study aimed to evaluate the effect of 30 g prebreakfast and 30 g predinner supplementation of pistachios for 12 wk on glycated hemoglobin (HbA1c), other glycemic markers, anthropometry, and lipid profile of Asian Indians with prediabetes.
Methods: In a 12-wk parallel arm, randomized controlled trial, we recruited 120 participants with prediabetes based on American Diabetes Association criteria.

Background: Appetite-regulating hormones are implicated in anorexia nervosa (AN) pathophysiology, however, data are limited for appetite-regulating hormones across the AN weight spectrum. We aimed to investigate fasting and post-prandial concentrations of appetite-regulating hormones - peptide YY (PYY), cholecystokinin (CCK), and ghrelin - among adolescent and young adult females across the AN weight spectrum, specifically those with AN and Atypical AN, and healthy controls (HC).
Methods: Participants (N = 95; ages 11-22 years) included 33 with AN, 25 with Atypical AN, and 37 HC.

Background: Dietary recommendations have globally shifted towards promoting the consumption of legumes as an environmentally friendly and healthy source of protein. This study investigated the replacement of red and processed meat, poultry or fish for equal amounts of legumes on the risk of non-alcoholic fatty liver disease (NAFLD).
Methods: UK Biobank participants who completed ≥ 2 dietary assessments and had complete covariate information were included in the analyses (N = 124,546).

Food serves not only as a source of individual physical sustenance but also a central element in shaping social relationships and culture within families and communities. The concept of foodscapes has emerged as a valuable framework for understanding the intricate connections between food, the environment, and society, highlighting both the physical and cultural dimensions of food. Production and consumption practices of traditional healthy foods, such as the Zambian traditional fermented milk mabisi, evolve over generations, a process influenced by the foodscape they are embedded in.
