Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Fish consumption has been increasing in recent decades due to consumer interest in the positive health effects of regular food intake, among other factors. Previous studies have described significant results on the acute consumption of fish products, favoring the reduction of triglycerides, total cholesterol, low-density lipoprotein, reduced insulin secretion, and increased plasma concentration of high-density lipoprotein during the postprandial period. Despite this scenario, studies investigating acute metabolic responses, such as postprandial physiological phenomena after consumption of the main fish species ingested by Brazilians, are still scarce. Thus, investigations of the acute effects of fish intake on postprandial metabolism may reveal new beneficial effects associated with this food group. The present proposal aims to compare the acute effects of the ingestion of two sources of fish and bovine protein on postprandial metabolism through the capillary blood sample collected within 5 hours after the ingestion of test meals, investigating hormones and inflammatory mediators and quantifying triglycerides, total cholesterol and non-esterified fatty acids and blood glucose, in addition to evaluating sensory aspects and satiety between different meals. It is expected to generate new data on postprandial physiology and investigate possible effects of fish ingestion that can contribute to public health management and healthy eating patterns.

Tambaqui meat

Tambaqui (Colossoma macropomum) meat intake, 7g per BMI unit

Group Type ACTIVE_COMPARATOR

Assessment of postprandial metabolism after intake of different meat

Intervention Type OTHER

30 healthy adults (15 male and 15 female) consumed sardines (Opisthonema oglinum, marine fish), tambaqui (Colossoma macropomum, freshwater culture), and beef (Bos taurus). The meal consisted only of meat, with 7g per BMI unit. The postprandial response was observed for 5 hours, after an overnight fast.
