About

This study evaluates the effect of different dietary conducts in the nocturnal period on the postprandial metabolism and food perceptions of night workers of the Hospital of Clinics of Uberlândia, Federal University of Uberlândia.

Full description

Due to imbalances in the circadian rhythm, shift workers may present inadequate eating habits, which provoke metabolic and nutritional disorders. In this crossover study the participants consumed, at different times and separated by 6 days interval, two meals pre-established at the time of night work: a control and a higher-protein. On the day of each intervention, the participants were evaluated for response of blood and subjective markers after meal (glucose, insulin, triglycerides and subjective perceptions related to ingestion after each meal). It is expected that the standardization of a glycemic reduction diet will improve the metabolic response of the workers, demonstrated in the results of the biochemical parameters. If this scenario is confirmed, it is still expected that the data and results obtained in this study may serve as subsidies for the elaboration of nutritional interventions consistent with the work routine at night.
