RESUMEN

Studies indicate that ultra-processed food (UP) consumption correlates negatively with essential vitamin and mineral intake and positively with sodium and lipid intake. The objective of this study was to explore the relationship between UP consumption and deviations from nutritional guidelines. An observational, cross-sectional analytical study was conducted on a probability sample of manufacturing workers in the state of Rio Grande do Norte, Brazil. Food consumption was assessed with a 24 h recall survey, and nutrient intake inadequacies were calculated as the difference between individuals' intake of energy, macronutrients, minerals and vitamins, and the dietary reference intakes for individuals of the same sex and age group, and then analyzed for trends across the percentage contribution of UP to total energy intake with nonparametric multiple regression adjusted for covariates. The study included 921 workers from 33 industries, 55.9% male, with a mean age of 32 years. Overall, the study population exhibited deficits in energy, all macronutrients, and in some micronutrients. With increasing UP contribution to total energy intake, there is a trend towards a greater intake of energy (p < 0.001), total, saturated, monounsaturated, and trans fats (p < 0.001), n6-polyunsaturated fatty acids (p = 0.03), carbohydrates (p < 0.001), calcium (p = 0.008), and manganese (p < 0.001), thiamin (p < 0.001), and vitamin B6 (p = 0.01); however, this comes with a negative consequence in terms of reducing the protein consumption (p = 0.037), fiber (p = 0.035), copper (p = 0.033), and vitamin E (p = 0.002) intake. The results show that correcting energy and micronutrient deficiencies by increasing UP consumption can also lead to a decrease in diet quality.

RESUMEN

OBJECTIVE: Children admitted to the intensive care unit (ICU) are at risk of not meeting their nutritional requirements. This study aimed to identify factors associated with failure to meet the dietary recommended intake (DRI) of zinc, selenium, cholecalciferol, and thiamine in critically ill children receiving enteral tube feeding during their stay in the ICU. METHODS: We analyzed prospectively 260 cases, corresponding to 206 patients who received enteral tube feeding for a minimum of 3 days up to 10 days during the first 10 d of ICU stay. Individual intake was compared to estimated average requirement (EAR) and adequate intake (AI) values during the first 10 d of ICU stay. The outcome variable was defined as not meeting the recommended intake of the micronutrients studied. Potential explanatory variables for the outcome were age <1 year, malnutrition (WHO), clinical severity scores, heart disease, severe sepsis or septic shock, use of alpha-adrenergic drugs, and renal replacement therapy (RRT). The effect of the explanatory variables on the outcome was analyzed by logistic regression analysis. RESULTS: The majority of patients did not meet the recommendations for micronutrients. After adjusting for covariates, age <1 year, malnutrition, heart disease, use of alpha-adrenergic drugs, and renal replacement therapy were associated with failure to meet the recommendations for at least one of the micronutrients studied. CONCLUSIONS: Factors associated with failure to meet the recommendations for micronutrient intake in children receiving enteral tube feeding during their ICU stay are linked to patients' low weight, restriction in fluid intake, and clinical severity of the disease.

RESUMEN

The Brazilian National School Feeding Program (PNAE) seeks to meet student's nutritional needs during the period they remain in school. This study aimed to determine the nutritional composition of meals provided in municipal day-care centres serving children of 7-11 months (group A) and 12-36 months (group B) of age and to compare observed values with the PNAE's and dietary reference intakes' (DRI) recommendations. This cross-sectional study was conducted in 4 day-care centres in the metropolitan area of Curitiba, Paraná, Brazil, between June and November 2013. Food samples of six daily meals were collected during 20 non-consecutive days, totalling 120 samples. For each meal, average served and consumed portions were submitted for laboratory analysis of moisture, ash, proteins, lipids, carbohydrates, dietary fibre, Na, Ca and Fe and compared with the PNAE's and DRI's values. No statistically significant difference was found between age groups (P=0·793) regarding portion sizes and nutritional composition. The same menu was offered to both groups in 95 % of the meals (n 114), although the groups' nutritional needs were different. For group A, served meals met PNAE's recommendations for energy, carbohydrates, proteins, Na and Ca content, and consumed portions provided 70 % of the nutritional needs for carbohydrates, proteins and Ca. For group B, served portions complied with the PNAE's values for proteins, Na and Ca. Proteins and Na reached 70 % of the nutritional needs when consumed food was evaluated. School feeding in day-care centres partially meet PNAE's guidelines and children's nutritional requirements, contradicting the primary objective established by the national programme.

RESUMEN

Fruits are rich in minerals, which are essential for a wide variety of metabolic and physiologic processes in the human body. The use of frozen fruits has greatly spread in the last years not only in the preparation of juices, but also as raw material for yogurts, candies, cookies, cakes, ice creams, and children's food. However, up to now there is no data about the mineral profile of frozen fruits. This is the first database to quantify the levels of minerals in 23 samples of frozen fruits, including the most used around the world and some native fruits from the Amazon rainforest in Brazil. Considering the Dietary Reference Intakes, 100g of frozen fruits can provide 0.2 to 2.8 percent of macro and 2.5 to 100 percent of microminerals for adults (31-50 years old). Although geographical differences should be considered, these data can help to plan diets and to develop population interventions aiming to prevent chronic diseases.


As frutas são ricas em minerais, sendo estes essenciais para uma grande variedade de processos metabólicos e fisiológicos no corpo humano. A utilização de frutas congeladas tem se ampliado nos últimos anos, não só na preparação de sucos, mas também como matéria-prima para iogurtes, doces, biscoitos, bolos, sorvetes e alimentos infantis. No entanto, até o momento não há dados sobre o perfil mineral de frutas congeladas. Este trabalho é o primeiro banco de dados para quantificar os níveis de minerais em 23 amostras de frutas congeladas, bastante consumidas em todo o mundo e de algumas frutas nativas da floresta amazônica, Brasil. Considerando-se as Referências de Ingestão Diárias, 100g de frutas congeladas podem fornecer 0,2-2,8 por cento de macro e de 2,5 a 100 por cento dos mi-crominerais para adultos (31-50 anos). Embora as diferenças geográficas devam ser consideradas, estes dados ajudam para o plano de dietas e desenvolvimento de intervenções junto à população co o objetivo de prevenir doenças crônicas.
