Brief Summary:
The aim of this study is to investigate if the application of lipid in various form (i.e. liquid and solid) affects glycaemia, lipaemia and insulinaemia. In addition, this study aims to test the lipidemic effects of the use of vegetable oil as a substitute in the application for making chocolate confectionery.
Detailed Description:
The study will have a randomized, non-blinded, crossover design. This study will explicitly compare the effects of different forms of fat (liquid and solid) on glucose, insulin and lipid response on 20 healthy male participants between the age of 21-40 years. In addition, this study aims to test the lipidemic effects of the use of vegetable oil as a substitute in the application for making chocolate confectionery.
All potential participants will be asked to attend four testing sessions and a screening session in total. During the first screening session, participants will receive an informed consent form and given ample time to go through it and rectify any queries they have. If they decide to take part in the study, they will be asked to sign the informed consent form. They will then be asked to complete a screening questionnaire, baseline measurements including anthropometric measurements, blood pressure, and fasting blood glucose will be collected from each participant in order to determine their eligibility. During the test sessions, participants' glycaemic, insulinaemic and lipaemic responses to the test meals will be measured. The test duration for each session will be 6.5 hours. Participants will be instructed to avoid strenuous physical activity for at least 3 days and avoid caffeine and alcohol consumption for at least 1 day prior to visiting the CNRC for their study trials. Participants will be provided with a standardized dinner meal (consisting of rice/noodles, vegetables, meat, drink/pudding) and to refrain from alcohol and exercise the day before their testing sessions.
Screening questionnaire: The screening questionnaire will include contact information, demographic and general health details. This information will be used to determine whether the participant is eligible for the study, as well as to check for any possible confounders that may influence the study outcomes.
Anthropometric measurements: Body weight and body composition will be measured using bioelectrical impedance analysis. Height will be measured using a stadiometer in order to calculate participants' BMI. Blood pressure will also be measured. All measurements will be taken in duplicate during the screening session. Waist circumference will be measured at the minimum circumference between the iliac crest and the rib cage. Hip circumference will be measured at the maximum protuberance of the buttocks. Biceps and triceps skinfold measurements will also be taken. Blood pressure will be measured using an Omron blood pressure monitor (Model HEM-907) at baseline. Participants will be seated for five minutes before blood pressure is measured. Measurements will be taken in duplicate and the averaged results will be recorded.
Blood collection: Participants will be asked to attend the testing sessions after an overnight fast of ten hours. At the beginning of the testing session, a cannula will be inserted into participants' arms. One fasting blood sample will be collected by venous cannulation. 3 milliliters (ml) of venous blood will be collected into Vacutainers® (Belton Dickinson Diagnostics) containing disodium EDTA for the analyses of plasma triglyceride, glucose and insulin concentrations. Participants will then consume treatment meal within 15 minutes. Blood samples will be taken at baseline, 15, 30, 45, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 and 360 minutes. The amount of blood that will be collected at every time point will be approximately 3ml. A maximum of 15 blood samples will be collected by cannulation. A total of 180ml of blood will be taken for the study. Glycaemic, insulinaemic, and lipaemic responses will be determined using the method described by Wolever and Jenkins. The area under the curve will be determined as the area of those increments above baseline only.
Test session: Participants will be provided a standard dinner meal to be consumed at home at 7pm the night before the test session. Afterwhich, they will be asked to not eat and drink anything except water after 10:30 pm. They will also be instructed to arrive at the CNRC the following morning after an overnight fast of 10-12 hours. After 10 minutes upon arrival, an indwelling catheter will be inserted into a vein in your forearm and will be kept patent (free of clots) for the remainder of the test session. We will then take a blood sample from the cannula to measure baseline values. After obtaining the baseline blood samples, participants will be given the test meal to consume within 15 minutes. Following the test meal, we will take further blood samples (from the cannula) for the next 15, 30, 45, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360 minutes. The cannula will be removed after the last time-point of blood sample collection (360 minutes) and they are free to leave CNRC. During the entire testing period the participants will be instructed to remain rested and in the laboratory. There will be no incidental findings as analysed samples are basic metabolites and therefore, reporting is not applicable.
