Group	Intervention	Description
Glucose as reference food	Glucose as reference food	Fourteen healthy, normal body weight adults (male: 6, female: 10) after 12hr fast, consumed 50g available carbohydrates from D-glucose, tested two times, in different visits as reference food; and 50g available carbohydrates from white bread, tested two times; and 50 gr available carbohydrates from spaghetti No7 types, regular, whole wheat and low carbohydrates - high fibre, tested once, in different visits, along with 300mL water.

Primary Outcome Measures

Name	Time	Method
Capillary blood glucose responses	2 hours	Clinically useful change in blood glucose, defined as the restoration of glucose within normal limits during the 2hr glucose tolerance test

Secondary Outcome Measures

Name	Time	Method
Subjective appetite ratings	2 hours	Useful change in subjective appetite using visual analogue scales with a score 0 to 10 (given in the form of booklet, one scale per page) at baseline, 15, 30, 45, 60, 90 and 120min. The minimum or maximum score will be evaluated if it is better or worse depending on the appetite variable e.g. hunger, satiety, desire to eat etc
Salivary insulin responses	2 hours	Clinically useful change in salivary insulin, defined as the restoration of insulin within normal limits during the 2hr glucose tolerance test
Blood pressure	2 hours	Useful change in systolic and diastolic blood pressure before and 2hr after consumption of the spaghetti products
