Healthy Clinical Trial - Omega-3 Fatty Acids on Fasting & Postprandial

Status Recruiting

Clinical Trial Summary

The aim of this project is to elucidate how repeated exposure with omega-3 fatty acid supplementation for 6 weeks affect mean and individual fasting lipids and inflammatory responses and postprandial TG after a high fat meal with butter (50 g fat) in healthy subjects.

Clinical Trial Description

The investigators aim to perform a randomized controlled crossover trial where each participant will act as his or her own control. Participants will be randomized to either start to receive fish oil (the omega-3 fatty acid supplement, dose of 2.3 g Eicosapentaenoic acid fatty acids (EPA) + Docosahexaenoic acid fatty acids (DHA) /day) for 6 weeks or a high-oleic sunflower oil (HOSO) containing no omega-3 fatty acids, as control followed by a wash-out period of minimum 12 weeks, before the treatment is changed for 6 weeks. Before and after each intervention period we will take fasting blood samples and collect spot morning urine. At home, the participant will perform a voluntary postprandial meal test with 61 g butter (containing 50 g fat), use DBS to collect fasting (0 h) 2, 4, 6, and 8 h blood samples after intake of the meal to measure TG which has been validated previously. The investigators will use first part of the trial to define fasting and postprandial TG responders and non-responders. The investigators will also monitor at home the postprandial TG response to HOSO to see the participants' postprandial response to a control oil without omega-3 fatty acids. After a 12 week wash-out period, we will then repeat the fish oil intervention period once more for all in order to see if those we defined as responders continue to be defined in the same category in the repeated fish oil intervention (adaptive design). The investigators will collect exposure data, including dietary intake, physical activity, and clinical data such as BMI, body composition (such as fat mass, visceral fat, fat free mass), blood pressure, lipids and glucose and specific single nucleotide polymorphism (SNPs) to understand the impact of these factors on the individual postprandial TG response. In addition, the investigators will collect feces samples before taken before each meal test day for gut microbiota analysis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
