Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the present study is to explore the influence of cooking methods on post-prandial glycaemia and its impact on satiety in children.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Each of the 5 study sessions will be at least 7 days apart. Either meal skipping, or one of three treatments of white potatoes (a) baked (with skin), (b) mashed, (c) fried French fries, or white bread, prepared on the day of testing, will be served to healthy children (9-14 years). Participants will consume the equivalent to 1 medium sized potato (\~280 kcal) or an equivalent amount of calories from white bread. Glycemic response, insulin, incretin hormones (glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic peptide (GIP)), dipeptidyl peptidase 4 (DPP4), and cholecystokinin (CCK) will be measured for 2 h (0, 15, 30, 45, 60, 90 and 120 min) following meal consumption, as well as mood and subjective appetite. An ad libitum test meal will be provided at 120 min to assess food intake suppression.
