Objective: The present study evaluates eating habits and behaviors, and nutritional and food safety knowledge of a group of Italian adolescents.
Design: A dietary questionnaire previously constructed and tested was self-administered during school time. Each section was evaluated using a separate score.
Setting: The study was carried out as a part of a nutritional surveillance project in the Aosta Valley Region, Northern Italy.
Subjects: Five hundred and thirty-two adolescent subjects, aged 15.4 +/- 0.7 years, attending the second year of secondary schools participated in the study.
Measures: We evaluated eating habits, physical activity, meaning of healthy and unhealthy dietary habits and food, self-efficacy, barriers affecting healthy food choices, nutritional and food safety, weight, height, Body Mass Index (BMI).
Results: Only 37.0% of the sample have satisfactory eating habits; 18.5% have a very active lifestyle; only 8.6% have quite good nutritional knowledge, 2.4% have satisfactory food safety knowledge, although 43.7% have good hygiene practices.
Conclusions: The results point out unhealthy behaviors influencing adolescents' eating habits and suggest which of these must be considered in order to develop tailored nutrition interventions, improving adolescents' consciousness aimed at adopting a healthy lifestyle.

Background And Objectives: Donor human milk (DHM) from a human milk bank (HMB) is used to feed low-birthweight (LBW) and preterm infants when mothers cannot provide their own breastmilk. The misuse of DHM could interfere with mothers' breastmilk and weaken breastfeeding efforts. This study aimed to identify factors behind prolonged DHM usage during the first six years of Vietnam's first HMB.

Objectives: Flour products with iodine-fortified dried vegetables can be a good source of iodine. However, in addition to iodine stability, the sensory quality of these products is also important. Therefore, this study aimed to assess the effect of adding iodine-fortified dried vegetables to flour products (gnocchi and ciabatta) on their sensory quality and map consumers (vegan/omnivore diets) as potential consumers of fortified flour products with iodine-fortified dried vegetables.
