• Registration Number: NCT03358745
• Lead Sponsor: Lund University

Brief Summary

The order in which the different components of a meal are eaten may have impact on the postprandial metabolic responses to carbohydrates, fat and proteins. This study will compare blood lipids and glycemia regulation following lunches of identical composition but varying the order of intake of the different meal components.

Detailed Description

The order in which the different components of a meal are eaten may have impact on the postprandial metabolic responses to carbohydrates, fat and proteins. Some of these responses are associated with the risk for developing cardiometabolic complications.

The study will be carried out in a cohort of healthy subjects with a wide BMI range and normal fasting glycemia. Postprandial metabolic responses to a reference meal starting with bread and butter (BB) will be compared with those registered after 3 other meals of identical composition, in which the starter will be permutated. Each meal is tested on an independent experimental session, with a 1 week washout interval.

The intervention will be carried out at the Food for Health Science Centre - Lund University. Additionally, the plan contemplates an initial information visit including screening of fasting blood glucose. In total, each volunteer completing the study will pay five visits to the clinical unit.

Based on the results from the above-described phase, a second step of the study will compare various quality attributes of the most effective starter on the impact on cardiometabolic risk markers, as a way to optimize putative protective actions and to gain further mechanistic insight.

Primary Outcome Measures

Name	Time	Method
Area under the curve of postprandial glycemia	4 hours postprandial	Area under the curve of postprandial glycemia (0-4h) after each intervention, compared to the reference meal.; Plasma glucose is measured pre-meal and and at various post-meal intervals for up to for 4 hours. AUC is calculated and compared to AUC recorded after the reference meal.

Secondary Outcome Measures

Name	Time	Method
Area under the curve (AUC) of postprandial triglyceridemia	4 hours postprandial	Area under the curve (AUC) of postprandial triglyceridemia (0-4h) after each intervention, compared to the reference meal
Area under the curve (AUC) of postprandial insulinemia	4 hours postprandial	Area under the curve (AUC) of postprandial insulinemia (0-4h) after each intervention, compared to the reference meal
Area under the curve (AUC) of postprandial Glucagon-like peptide (GLP-1), Peptide YY (PYY) and glucose-dependent insulinotropic polypeptide (GIP)	4 hours	Area under the curve (AUC) of postprandial GLP-1, GIP and PYY (0-4h) after each intervention, compared to the reference meal
