Postprandial responses to fish intake

Previous studies have linked the consumption of fish products to the reduction of plasma triglycerides, cholesterol, low-density lipoprotein, insulin secretion, and increased plasma concentration of high-density lipoprotein. Despite this scenario, there are still few studies investigating acute metabolic responses, such as postprandial physiological phenomena after consumption of the main ichthyic species ingested in Brazil. Considering that protein composition and digestibility of fish are different to other dietary protein sources, such as beef, it is expected that postprandial responses to fish consumption will also be different. The investigation of the acute effects of fish intake on postprandial metabolism may reveal new beneficial effects associated with this food group, which could be added to the chronic nutritional benefits already reported. The present proposal compares the acute effects of the ingestion of fish and beef on postprandial metabolism. We are expecting to generate new data on postprandial physiology and unravel new effects of fish intake that could contribute to public health management.
