Pragmatic Carbohydrate Quality Metrics in Relation to Glycemic Index, Glycemic Load, and Front-of-Pack Warning Labels in Grain Foods.

The challenges in the characterization of the nutritional quality of grain foods comprise obstacles to public health actions toward promotion of healthier grain-based foods. The present study investigated how carbohydrate metrics related to glycemic index (GI), glycemic load (GL), and warning labels of grain foods consumed by individuals living in São Paulo, Brazil. Information on intake of grain foods at individual level was obtained using 24 h recalls within a cross-sectional population-based survey conducted in 2015.

Exploring Diet and Nutrient Insufficiencies across Age Groups: Insights from a Population-Based Study of Brazilian Adults.

Assessing dietary inadequacies can contribute to understanding the nutritional vulnerabilities of a country. This study aimed to investigate nutrient intakes and micronutrient inadequacies in the Brazilian adult population, with an interest in different age subgroups. We conducted a cross-sectional study with 1812 individuals aged 19 to 65 years from a population-based study with a representative sample of Brazilian adults.

Body composition affects the accuracy of predictive equations to estimate resting energy expenditure in older adults: An exploratory study.

Background: To investigate the accuracy of ten different predictive equations to estimate resting energy expenditure (REE) in a sample of Brazilian older adults and develop a predictive equation for estimating REE based on body composition data.

Methods: A cross-sectional study with thirty-eight Brazilian older adults aged 60-84 years, who had their REE measured by indirect calorimetry (IC) and BC assessed by dual-energy x-ray absorptiometry (DXA). REE was compared to the estimation of ten predictive equations, and the differences between BC and anthropometric-based equations were investigated using Bland-Altman plots and Lin's concordance correlation.

Misreporting of Energy Intake Is Related to Specific Food Items in Low-Middle Income Chilean Adolescents.

Background: Misreporting of energy intake (EI) in self-reported dietary assessment is inevitable, and even less is known about which food items are misreported by low-middle income adolescents. We evaluated the prevalence of misreporting of energy intake and its relationship with nutrients and food intake.

Methods: We analyzed 24 h dietary recalls collected from 576 adolescents (52.

Integrative Strategies for Preventing Nutritional Problems in the Development of Children in Brazil.

Child healthcare has been a priority subject in several programs and public policies developed over the decades. However, initiatives implemented seem insufficient to overcome the challenges regarding the integral development and improvement of the nutritional status of children in Brazil. The initial developmental stages of a child include pregnancy, breastfeeding, and complementary feeding, which are determinants in future aspects of health and nutritional status.

Misreporting of dietary energy intake obtained by 24 h recalls in older adults: a comparison of five previous methods using doubly labeled water.

Background/objective: To test five different methods to detect misreporting in comparison to doubly labeled water in a sample of older adults.

Subjects/methods: A cross-sectional study with thirty-eight Brazilian community-dwelling older adults aged 60-84 years, who had their total energy expenditure measured by doubly labeled water (TEE). Dietary data were collected by two 24 h recalls.

Nutrition Related-Practices in Brazilian Preschoolers: Identifying Challenges and Addressing Barriers.

Over the past decades, Brazil has faced important challenges regarding the nutrition of toddlers. Changes in dietary intake and feeding habits switched the scenario from undernutrition to increased rates of overweight and obesity. Determinants related to that issue involve the disparity in income distribution, the structure of food production and access, and the role of programs and policies, mostly related to its historical context.

Estimating total daily energy requirements in community-dwelling older adults: validity of previous predictive equations and modeling of a new approach.

Background/objectives: Accurate estimation of energy requirements is crucial for health maintenance and prevention of malnutrition in older adults. This study aimed to assess the accuracy of predictive equations for estimating energy requirements in older adults and to test the validity of new predictive equations for this age group.

Subjects/methods: This is a cross-sectional study including 38 Brazilian community-dwelling older adults aged 60-84 years, who had their total energy expenditure measured by doubly labeled water (TEE).
