Eleven healthy subjects (male: 6, female: 5) after 10-14h fast, consumed 50 g D-glucose, three times, in different weeks along with 250 mL water; and 50 g D-glucose containing 15 mg and 30 mg of Crocus Sativus tested once, in different weeks along with 250 mL water. Fingertip capillary blood glucose samples were taken at 0, 15, 30, 45, 60, 90 and 120 min postmeal. The first glucose sample was taken exactly 15 min after the beginning of the consumption of the tested beverage.

Capillary blood glucose responses
Clinically useful change in blood glucose, defined as the restoration of glucose within normal limits during the 2-hour oral glucose tolerance test
Time frame: 2 hours
Subjective appetite ratings
Useful change in subjective appetite using visual analogue scales with a score from 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.
Time frame: 2 hours
Blood pressure
Useful change in systolic and diastolic blood pressure before and 2-hour after consumption of the three beverages
Time frame: 2 hours
