Adapting a US dietary analysis software and nutrient database for use in Brazil.

In many countries, assessing food and nutrient intake for research and surveillance purposes is difficult due to the lack of comprehensive, country-specific food and nutrient databases and/or a dietary analysis software program. In this case study, we describe the approach used to adapt a United States (US) dietary analysis software and nutrient database (Nutrition Data System for Research [NDSR]) for use in analyzing 24-hour dietary recalls collected for the Brazil Kids Nutrition and Health Study (KNHS). A team of experts that included individuals knowledgeable about Brazil and US eating traditions was assembled to devise solutions for between-country differences in eating habits, food supply, food nomenclature, and language.

Impact of Nighttime Food Consumption and Feasibility of Fasting during Night Work: A Narrative Review.

Shift work has been associated with an increased risk of developing chronic non-communicable diseases, such as obesity. The reduction in overnight fasting and its physiological consequences seem to affect the metabolic health of shift workers, but little has been discussed regarding the feasibility and implications of maintaining a night-long fast during work. This narrative review aims to discuss the impact of eating behavior on the reduction of overnight fasting in shift workers, as well as possible nutritional strategies involving fasting that have been tested for shift workers, to contribute to the establishment of nutritional guidelines for them.

Meal timing variability of rotating shift workers throughout a complete shift cycle and its effect on daily energy and macronutrient intake: a field study.

Purpose: To evaluate the meal timing variability of rotating shift workers throughout a complete shift schedule and its effect on daily energy and macronutrient intake.

Methods: Thirty male shift-workers from a mining company were evaluated in a complete rotation shift cycle over 240 consecutive hours (10 days; two days of morning shifts, two days of evening shifts, 24 h free, two days of night shifts and three days off). Food intake related variables [meal timing, energy (kcal) and macronutrient intake (%)] were assessed by 24 h recall by a trained nutritionist.

Nutrient Intakes among Brazilian Children Need Improvement and Show Differences by Region and Socioeconomic Level.

Brazil is the most populous country in South America. Using 24 h dietary data, we compared the nutrient intakes of 4-13-year-olds to reference values and tested for regional and socioeconomic (SES) differences. A considerable proportion reported intakes below the Estimated Average Requirements (EAR) for vitamins E (78.

Eating Duration throughout a Rotating Shift Schedule: A Case Study.

Objective: The impact of the rotation between different shifts and free days within a short period of time on the food consumption is poorly addressed in the literature. Our objective was to characterize the eating duration (ED) over 10 d of clockwise rotating and to associate it with the intake of energy and macronutrients.

Methods: Thirty male shift-workers from a mining company were evaluated over a complete rotation shift schedule of 10 consecutive days (2 d of morning shifts, 2 d of afternoon shifts, 24 h free-day, 2 d of night shifts, and three free days).

Eating Late Negatively Affects Sleep Pattern and Apnea Severity in Individuals With Sleep Apnea.

Study Objectives: This study aimed to analyze the association between habitual meal timing and sleep parameters, as well as habitual meal timing and apnea severity in individuals with obstructive sleep apnea (OSA).

Methods: Patients in whom mild to severe OSA was diagnosed were included in the study (n = 296). Sleep parameters were analyzed by polysomnography.

The association between anxiety, hunger, the enjoyment of eating foods and the satiety after food intake in individuals working a night shift compared with after taking a nocturnal sleep: A prospective and observational study.

Subjective responses to meals are altered by shortened sleep time and anxiety state, but this effect has been poorly studied in shift workers - who act as a typical model concerning sleep restriction and present high levels of anxiety. The objective of this study was to compare subjective perceptions of meals and the levels of anxiety in the same subjects after working night shifts and after taking a nocturnal sleep, and to investigate associations between the responses to meals and the levels of anxiety under these two conditions. The study evaluated 34 male permanent night-shift workers who worked a 12-h shift followed by a 36-h rest period.

[Brazilian Food Composition Database (TBCA-USP): Data compilation to serve the public good].

The article shows the evolution of the Brazilian Food Composition Database (TBCA-USP), since its creation until its next update. The article characterizes the TBCA-USP database like a public good and highlights the importance of the food composition data compilation as a high cost-effective activity. It reports the social relevance of the information about food composition and the importance of this database in the national context.

Impact of dietary fiber energy on the calculation of food total energy value in the Brazilian Food Composition Database.

Dietary fiber (DF) contributes to the energy value of foods and including it in the calculation of total food energy has been recommended for food composition databases. The present study aimed to investigate the impact of including energy provided by the DF fermentation in the calculation of food energy. Total energy values of 1753 foods from the Brazilian Food Composition Database were calculated with or without the inclusion of DF energy.

Application of Choices criteria in Brazil: impact on nutrient intake and adequacy of food products in relation to compounds associated to the risk of non-transmissible chronic diseases.

One of the aims of this work was to evaluate the impact of introducing products that are in agreement with the Choices criteria in the usual diet of the Brazilian population. However, due to the insufficient information on key compounds related to non-transmissible chronic diseases (NTCD) in the national food composition database, the nutritional information of food labels was collected. A food composition database of industrialized products was created (1720 products) and their data were evaluated according to the Choices criteria.
