Background: The rise of digital platforms as sources of nutrition information has highlighted the need for digital healthy eating literacy to ensure informed dietary choices. Understanding the role of digital healthy eating literacy in shaping sustainable dietary behaviours is crucial for promoting both individual and planetary health. This study aimed to examine the associations between digital healthy eating literacy, environmentally responsible food choices, and adherence to the Mediterranean diet (MedDiet), a sustainable dietary model, among adults in Türkiye. Methods: A total of 1,516 adults (mean age: 28.9 ± 9.8 years) residing in Türkiye were recruited through an online survey distributed via social platforms. Participants completed an online questionnaire comprising the e-Healthy Diet Literacy (e-HDL) Questionnaire, the Environmentally Responsible Food Choice Scale, and the 14-item Mediterranean Diet Adherence Screener (MEDAS). This cross-sectional study employed multivariable regression analyses to examine the associations between digital healthy eating literacy, environmentally responsible food choices, and adherence to the MedDiet. Results: Higher e-HDL scores were significantly associated with increased environmentally responsible food choices (β = 0.283, 95% CI: 0.233–0.333, p < 0.001) and a 1.039-fold increase in the odds of adherence to the MedDiet (95% CI: 1.021–1.058, p < 0.001). The strength of the association between e-HDL and the outcomes varied by subgroup, with stronger associations observed for environmentally responsible food choices among non-smokers, non-drinkers, daily exercisers, and higher-income individuals, and for adherence to the MedDiet among women, non-smokers, non-drinkers, and those with lower or equal income levels. Among the MedDiet adherents, e-HDL explained 10.5% of the variance in environmentally responsible food choices (p < 0.001). Conclusions: This study highlights the potential importance of digital healthy eating literacy in relation to sustainable dietary behaviours and environmental health. Targeted digital nutrition education programmes may help support improvements in digital healthy eating literacy and encourage sustainable diets, supporting planetary health. Future policies should focus on increasing awareness and accessibility of reliable nutrition information on digital platforms to improve dietary practices and environmental sustainability.

Parents can help children adopt good eating habits early in childhood by encouraging them to eat healthy. While parents’ levels of nutritional literacy is known to play a role in children’s healthy nutrition, healthy food is also essential in improving oral-health-related quality of life (OHRQoL). Since the effect of parents’ nutritional literacy on children’s OHRQoL is not yet known, this study aimed to examine the impact of parental nutritional literacy on children’s OHRQoL. This study was conducted with 459 parents of children aged 3–6 living in the Central Anatolia Region of Türkiye. Data collection tools included a sociodemographic form, the Early Childhood Oral Health Impact Scale (ECOHIS) and the Evaluation Instrument of Nutrition Literacy on Adults (EINLA). Data were analyzed in SPSS, using Student’s t-test, Chi-square test, and binary logistic regression models. Parents with higher nutritional literacy tend to have higher levels of education. An increase in total nutritional literacy score, especially in the general nutrition knowledge (GNK) and food label and numerical literacy (FLNL) subscales, was associated with higher child OHRQoL. Increasing parents’ nutritional literacy levels can contribute to OHRQoL by enabling them to be good role models for their children. Therefore, increasing parents’ nutritional literacy can improve OHRQoL by improving children’s nutrition and can be considered a protective factor for oral health.

Background: The oral microbiota is the largest and most diverse microbial community in the human body, shaped by numerous factors such as body composition, dietary habits, and oral health status. However, relationships between these parameters and the salivary microbiota in adolescents are not yet well understood. Objectives: This study aimed to characterize the salivary microbiota of healthy Turkish adolescents and to examine its associations with body mass index (BMI), diet quality, decayed-missing filled teeth (DMFT) index, and community periodontal index of treatment needs (CPITN). Methods: A descriptive, cross-sectional study was conducted among 40 adolescents aged 14–18 years, classified into four BMI z-score categories (underweight, normal weight, overweight, and obese). Anthropometric measurements, nutritional information, and oral health parameters (DMFT, CPITN) were assessed. Unstimulated saliva samples were collected, and the V3–V4 region of the 16S rRNA gene was sequenced using Illumina MiSeq. Alpha and beta diversity, differential abundance (LEfSe), and correlations with HEI components were analyzed. Results: Underweight adolescents exhibited significantly higher alpha diversity than obese participants (p = 0.024), while beta diversity did not differ across BMI, HEI, DMFT, or CPITN categories. LEfSe analysis revealed BMI-specific taxa: Leptotrichia sp., Haemophilus sp., and Treponema socranskii were enriched in the underweight group; Prevotella denticola in the obese group; and Selenomonas sputigena in the normal-weight group. HEI components, including whole fruits, whole grains, and plant-based proteins, showed positive correlations with Desulfobacterota and Proteobacteria. Poor oral hygiene was associated with higher species richness but not with large shifts in community structure. Conclusions: Salivary microbiota diversity and composition in adolescents vary with BMI, diet quality, and oral hygiene. These patterns are consistent with the idea that targeted nutritional and oral health interventions could influence the salivary microbiome during adolescence.

Pediatride Tip 1 diyabet ve çölyak hastalığı birlikteliğine sıklıkla rastlanmaktadır. Bu birlikteliğin tıbbi beslenme tedavisinde, karbonhidrat sayımı ve glutensiz diyet önerilmektedir. Ayrıca, bu hastalıklara besin alerjisinin de eklenmesi tıbbi beslenme tedavisini daha da zorlaştırmaktadır. Büyüme ve gelişmesinin devam etmesi ve iyi bir metabolik kontrolün sağlanması için gluten içeren ve alerjen besinlerin elimine edildiği, karbonhidrat sayımı modelinin uygulandığı bir beslenme programının diyetisyenler tarafından planlanması gerekmektedir. Bu makalede Tip 1 diyabet, çölyak hastalığı ve besin alerjisi birlikteliği olan bir pediatrik olgu sunulmuştur.

Pregestasyonel diyabetli gebelerde maternal, fetal ve neonatal komplikasyonların ortaya çıkma riski artmaktadır. İntrauterin çevre; gen ekspresyonundaki değişiklikler, oksidatif stres ve epigenetik modifikasyon gibi yolaklar üzerinden fetal programlanmaya katkıda bulunur. Özellikle fetüsün maternal dönemde hiperglisemi ile karşılaşmış olması intrauterin çevresi için endişe verici bir konudur. Bu nedenle hiperglisemi riski olan bireylerde, gebelik öncesi dönemde glisemik kontrol sağlanana kadar aile planlaması yapılmalıdır. Gestasyonel dönemde ise fetal riskleri ve gebelik komplikasyonlarını en aza indirgeyebilmek için ortalama kan glukoz düzeyi 100 mg/dL (5.6 mmol/L) ve HbA1c değeri <%6 seviyelerinde tutulmalıdır. Fetal programlamanın etkisi anne karnındaki olumsuz çevresel koşullara maruziyet süresi ile yakından ilişkilidir. Diyabetik ortam, anne ve fetüs arasında kanal görevi gören plasentada değişikliklere neden olarak erken dönemde gebelik kaybı, büyümenin kısıtlanması, preeklampsi riskinin artışı ve plasentomegaliye yol açabilir. Bu derlemenin amacı, pregestasyonel diyabetli gebelerde fetal programlamanın sonuçları hakkında genel bir bakış açısı sağlamaktır.
