Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Glucose as reference food; Twelve healthy, normal weight subjects (male: 7, female: 7) after 10-14 hr fast, consumed 25g available carbohydrate from D-glucose, three times, in different weeks as reference food along with 250ml water; and 25g available carbohydrates from lentils and lupins, trahanas with tomato sauce and halva with currants, tested once, in different weeks along with 250ml water.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	2 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 120 min. 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.	2 hours
Blood pressure	Useful change in systolic and diastolic blood pressure before and 2hr after consumption of three mixed meals	2 hours
