A scoping review of intermittent fasting, chronobiology, and metabolism.

Chronobiology plays a crucial role in modulating many physiologic systems in which there is nutritional synergism with meal timing. Given that intermittent fasting (IF) has grown as a flexible dietary method consisting of delayed or early eating windows, this scoping review addresses the effects of IF protocols on metabolism as they relate to clinical nutrition and the circadian system. Although nocturnal habits are associated with circadian misalignments and impaired cardiometabolic profile-and nutritional physiology is better orchestrated during the day-most findings are based on animal experiments or human studies with observational designs or acute meal tests.

Dietary recommendations during the COVID-19 pandemic.

Optimal nutrition can improve well-being and might mitigate the risk and morbidity associated with coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This review summarizes nutritional guidelines to support dietary counseling provided by dietitians and health-related professionals. The majority of documents encouraged the consumption of fruits, vegetables, and whole grain foods.

Development of a Food Frequency Questionnaire for Brazilian athletes.

Aim: Until recently most dietary survey methods have been developed for non-athletic populations. In this study, we aimed to develop a Food Frequency Questionnaire (FFQ) to assess the regular dietary intake of Brazilian athletes.

Methods: We interviewed 141 athletes (23.

Pre-season dietary intake of professional soccer players.

Background: Despite the well-documented importance of nutrition in optimizing performance and health, the dietary intake of soccer players has attracted little attention.

Aim: We aimed to assess the pre-season dietary intake of professional soccer players and its adequacy in macro and micronutrients.

Methods: The pre-season dietary intake of 19 male athletes was assessed using a semi-structured 3-day food record.

[Adolescent health risk behaviors and Family Health Strategy educational activities in Cuiabá, Mato Grosso State, Brazil, 2011].

Objective: to analyze health risk behaviors in adolescents and Family Health Strategy (FHS) educational activities in Cuiabá, Mato Grosso State, Brazil.

Methods: a cross-sectional study was conducted using data from a survey with adolescents registered with FHS in 2011/2012; Poisson regression was used to estimate prevalence ratios (PR) and 95% confidence interval (CI95%).

Results: there was low participation in educational activities on alcohol (23%), food (10%) and physical activity (9%); insufficient physical activity was higher in girls (PR=0.

Background: Many factors can influence an athlete to consume dietary supplements, such as age, sex and sports, among others. Few studies regarding the prevalence and associated factors are available for athletes, especially in developing countries.

Objective: The aim of the study was to determine the factors associated with the consumption of dietary supplements among Brazilian athletes.
