Postprandial Responses to Fish Intake

Brazil30 participantsStarted 2024-03-22

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
