Objectives: This review explored the relationship between knowledge among children and adolescents and their dietary behaviour. Content: Potentially eligible original research articles were identified through a systematic search in PubMed, SCOPUS, Web of Science and WHO Virtual Health Library from 2000 to 2018. From the initial search, a total of 7,258 research articles were obtained. Duplicate studies were identified and removed. Observational studies on children and adolescents (5–19 years) of any gender, ethnicity and country were included in which the outcome measured was either a scoring of/ association between nutrition knowledge and practices. After screening using the inclusion criteria, 13 studies were selected for this paper. Summary and Outlook: Four studies reported non-significant association between overall nutrition knowledge and practices. Only two studies found a significant association, out of which one showed a weak association highlighting that nutrition knowledge is not sufficient to result in healthy eating. Other factors which showed significant but weak associations with knowledge/practices included age, gender, nutritional status and lifestyle, peer influence, parents’/guardians’ knowledge, education and occupation level. The causal relationship couldn’t be examined in the present review due to the cross-sectional nature of the studies. Besides imparting knowledge through nutrition education interventions, there is a need for holistic behaviour change strategies including supporting food skills like menu planning, food shopping and cooking to encourage healthy eating habits among children. These interventions should target children from an early age, involving family/parents, teachers and peers to facilitate improvement in the food environment for sustainable change.

Objective: This study assessed diet diversity and consumption of ultra-processed foods and explored its impact on macronutrient intake and risk of micronutrient inadequacy.Design: Cross-sectional, non-probability snowball sampling.Setting: Nutrient intake was assessed using 24-h dietary recall method and diet diversity through FAO-diet diversity score (DDS). Mann–Whitney U test was used to assess differences in risk of inadequacy across gender. Spearman’s rank correlation assessed associations between energy contributed by ultra-processed food and risk of nutrient inadequacy.Participants: A total of 589 adults (20–40 years) belonging to upper-middle and high-income groups.Results: The average individual DDS was 4·4 ± 0·6. Most of the participants (>80 %) had intakes less than national recommendations of pulses/eggs/flesh foods, milk/milk products, fruits, vegetables and nuts. Ultra-processed foods contributed to 17 % of total energy intake, 12 % of protein, 17 % of carbohydrate, 29 % of added sugar, 20 % of total fat and 33 % of Na intake. The average risk of nutrient inadequacies for Zn (98 % v. 75 %), folate (67 % v. 22 %) and niacin (83 % v. 44 %) was higher among males than females (P < 0·001). The average risk of nutrient inadequacies for Fe (58 % v. 7 %), vitamin B₆ (95 % v. 90 %) and vitamin A (68 % v. 44 %) was higher among females than males (P < 0·001). There was a positive correlation between energy contributed by ultra-processed food and risk of niacin (ρ = 0·136, P = 0·001) and folate (ρ = 0·089, P = 0·049) inadequacy.Conclusion: Reformulating ultra-processed food to reduce fat, sugar and salt and increase micronutrients and behaviour change communication strategies that promote dietary diversity will improve micronutrient adequacy and diet quality.

Since the beginning of space missions, the food systems have undergone a sea change with prolonged manned missions and permanent space habitats. We have a better understanding of physiological changes which happen in humans in space and help in adaptation to the space environment. Yet, much remains underexplored and warrants further research. : Space missions today involve a considerable number of individuals operating in a microgravity environment for both short and long periods. The provision of food for such missions and managing the physio-pathological changes that affect nutritional requirements continue to be challenging. Food systems (food and beverages) used during every program to date have been shelf‐stable and were composed primarily of rehydratable or thermostabilized food items. Such foods usually have a lower hedonic value than fresh or frozen foods. Consequently, a reliable food system must provide a wide range of palatable and attractive foods as well as the tools to prepare them (through rehydration, heating, and cooling) to enhance the taste sensation of the crew. Adequate nutrition with easily accessible food is essential to this effort. To deliver nutritional recommendations to crew members for long-duration space missions, it is important to understand how nutritional status and general physiology are linked and affected by microgravity exposure. In view of this, it has been pointed out that nutritional countermeasures could rectify the physiological and behavioural anomalies during microgravity exposure. In this comprehensive narrative review, we have provided an overview of a few recent advances such as silkworm protein, good mood-vegan diet, 3-D food printing, and space garden’s produce for onboard support to food systems. It has also been found that exercise could be an addition to nutritional interventions. Areas of space exploration that require more in-depth research using ground-based bed rest models, as well as inflight microgravity conditions, are highlighted.

Nutritional inadequacies lead to various health problems among Indians. Improvements in diets can be addressed when different aspects of diet quality are known. The primary objective of the study was to assess diet quality of Indian adults belonging to the high-income group. The study also wanted to compare the suitability of two diet quality indices for use in the Indian scenario. A cross sectional study design with non-probability purposive sampling was used to collect data from 589 adults (20-40 years) in Delhi, India. Nutrient intake was assessed using the 24- hour dietary recall method. Two internationally recognized diet quality indices - Diet Quality Index- International Score (DQI-I) and the Global Diet Quality Score (GDQS) were selected to measure diet quality. 78% of the participants had poor diet quality using the DQI-I; the average score was 56.4 ± 5.6. The average DQI-I component scores for variety, adequacy, moderation and overall balance were 13.1±2.6, 27.5±2.2, 15.3±2.9, 0.43±0.9 respectively. Females were more likely (OR=2.07, 95% C.I.: 1.26 – 3.401) to have DQI-I scores in the lowest quartile (p=0.04). 88% had a moderate risk of nutritional inadequacy while 11% were at a high risk of nutritional inadequacy on the basis of their GDQS scores, the average of which was 16.9±2.1. There was a positive association between GDQS and DQI- I scores (ρ =0.316, p<0.001). The GDQS is better for assessing nutrient adequacy with healthy and unhealthy food consumption being compared. On the other hand, DQI-I gives a composite score combining the nutrient and food group intake and observes variety, adequacy, moderation and overall balance. Behaviour change communication strategies that encourage healthier food selection and promote dietary diversity may help improve nutritional quality of diets in Indian populations such as this one.

Background/Objectives: Poor dietary habits are a major contributor to non-communicable diseases (NCDs), the leading cause of mortality worldwide. To promote healthier eating, governments and stakeholders have implemented various nutrition policies, including front-of-pack nutrition labeling (FOPNL). The Choices International Foundation (Choices), through its criteria, supports these efforts through its standardized nutrient profiling system (NPS). Originally developed to underpin a positive FOPNL logo, in 2021, the criteria were expanded into a globally oriented five-level profiling system covering 23 basic and 10 discretionary food groups, addressing key nutrients such as trans-fatty acids, saturated fat, sodium, sugar, fiber, and energy. To ensure continued scientific relevance, the Choices criteria are periodically reviewed by an independent International Scientific Committee (ISC). Methods: This paper presents the 2025 revision of the Choices criteria, focusing on priority areas identified through stakeholder consultation and recent scientific developments. Results: Key updates include the introduction of nutrient-based equivalence criteria for plant-based alternatives to meat and dairy, based on protein and selected micronutrient thresholds. Non-sugar sweeteners (NSSs) were newly included as a factor that lowers a product’s health classification and makes it ineligible for a positive FOPNL. Additionally, the industrially produced trans-fatty acid (iTFA) criteria were revised and aligned with the latest World Health Organization (WHO) recommendations, improving both technical feasibility and policy coherence. While options for incorporating whole-grain and micronutrient criteria were explored, these were not included in the current revision. Conclusions: The 2025 update system enhances the scientific rigor, policy alignment, and global applicability of the Choices system. By providing a harmonized and evidence-based tool, it aims to support national policies that foster healthier food environments and, ultimately, improve public health outcomes worldwide.
