About

The primary aim of this study is to determine the effectiveness of durian on thermic effect of food (TEF), blood pressure, heart rate and postprandial glucose and lipid levels in young healthy men and women, compared to the ingestion of isocaloric banana.

Full description

Visit 1: Consenting and screening for study criteria. Visit 1 consists of consenting and screening session. Potential subjects will arrive at CNRC at 8h30 after 10-hour overnight fast (at least), only allowed access to water. A copy of written participant information sheet and informed consent form (ICF) will be given for them to read through carefully with needed time, and they may question for unclarity. Upon satisfaction, subjects must sign the ICF prior to the study procedures. After the consent, subjects will be screened for their eligibility with health screening questionnaire, and undergo anthropometric measurements (i.e. weight, height, waist circumference, and hip circumference). BMI will be calculated using formular weight divided by meter square (kg/m2). Blood pressure and heart rate readings will be taken. Body composition will be assessed using bioimpedance (BIA). Female subjects will be required to perform a β-HCG test using a urinary pregnancy test kit. Fasting glucose test will be performed through finger prick.

Visit 2 and 3: Intervention study (durian or banana will be assigned randomly) Visit 2 and visit 3 correspond to test session. Female subjects will be tested in the follicular phase of the menstrual cycle (the last menstrual cycle will be noted during screening and regular follow-up for the update). On each test day, subjects will arrive at CNRC at 8h30 after 10-hour overnight fast (at least), only water is allowed. They will undergo anthropometric measurements, and then instructed to lay comfortably on a bed in a suite (room temperature 22-24°C) for 45-minute of resting metabolic rate (RMR) measurement. Blood pressure, heart rate, fasting blood glucose, and fasting lipid will be performed before the meal test. At 9h30, subjects will be served 250g of durian or 417.6g of banana in a plate with 200 mL of water, and requested to consume the entire test meal within 10 min. Thermic effect of test meal will be performed after ingestion for 3 hours. Blood glucose fluctuation will be measured at 15 min, 30 min, 60 min, 90 min, 120 min, 180 min, and lipid fluctuation will be measured at 60 min, 120 min, and 180 min by finger prick. Blood pressure and heart rate readings will be taken at 30 min, 60 min, 120 min, 180 min.
