Arm Description

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. There was a washout period of at least two days between visits. Fingertip capillary blood glucose and salivary insulin samples were taken at baseline, 15, 30, 45, 60, 90 and 120min after food consumption. The first glucose and salivary insulin sample was taken exactly 15min after the first bite of food or drink.

Outcomes

Primary Outcome Measures

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

Secondary Outcome Measures

Salivary insulin responses
Clinically useful change in salivary insulin, defined as the restoration of insulin within normal limits during the 2hr glucose tolerance test
Subjective appetite ratings
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
Blood pressure
Useful change in systolic and diastolic blood pressure before and 2hr after consumption of the spaghetti products
