- Commercial baby foods aimed at children up to 36 months : are they a matter of concern?Publication . Santos, Mariana; Matias, Filipa; Loureiro, Isabel; Rito, Ana Isabel; Castanheira, Isabel; Bento, Alexandra; Assunção, RicardoProper nutrition in infancy and early childhood is crucial to ensuring optimal child development, growth, and better health outcomes later in life. The nutrient profile model proposed by WHO/Europe aims to assess the nutritional quality and promotional/marketing aspects of commercial baby foods aimed at children up to 36 months. We used commercial data from 191 baby foods collected between March 2021 and July 2021, from eight supermarket chains in the Lisbon Metropolitan area. According to the model specifications and the NOVA classification system, we assessed the nutritional quality and promotion aspects and the degree of processing, respectively. The presence of at least one sugar-contributing ingredient was found in 34.0% of the products; 13.9% of products listed sugars and 15.0% listed fruit juices or concentrates as an ingredient. The claim “No added sugar” was present in 69.6% of products. Only 35.1% of products comply with all the nutritional requirements of the model. Concerning processing classification, 61.8% of products were ultra-processed, and about 57.0% were indicated for children < 12 months. These findings reinforce the importance of implementing measures to ensure that commercial foods for infants are marketed appropriately and to promote foods with a lower degree of processing.

- Studying iodine intake of Portuguese children school mealsPublication . Delgado, Inês; Ventura, Marta; Gueifão, Sandra; Assunção, Ricardo; Coelho, Inês; Bento, Alexandra; Silva, José Armando L.; Castanheira, IsabelIodine is an essential trace element, and its nutritional importance is well established. The iodine content of school meals of Portuguese children aged between 6 and 10 years (collected in the metropolitan area of Lisbon) was analyzed by ICP-MS. The samples were cooked with and without iodized salt and additionally some complementary foods were purchased as supplements to the main meals or to the other meal along the day. The results report six meals per day and they suggest that at least one main meals (lunch or dinner) prepared with iodized salt is enough to reach the recommended daily iodine intake (AI), 90 µg/day, not exceeding the tolerable upper intake (UL) level of 300 µg/day. When both main meals are cooked without iodized salt, 11 % of the hypotheses present an iodine content less than 90 µg/day. However, when lunch and dinner are prepared with iodized salt, 1 % exceeds the value of the UL. The food groups with the highest levels of iodine are daily products and fish. These results presuppose a balanced diet without any dietary restrictions. So, for ideological or medical reasons, special attention must be paid to diets with some limitations, such as vegetarian, lactose or high content of proteins free diets.
