This study determined the glycemic index and glycemic load of six Greek honey varieties
This randomized, double-blind, cross-over study investigated the glycemic response to six Greek honey grades differing in floral source and carbohydrate composition. Isoglucidic test meals (50g available carbohydrate) and 50g glucose reference were given to 11 clinically and metabolically healthy, fasting individuals (27±7 years; 9 women; BMI 24±4kg/m2), in random order. GI was calculated using the FAO/WHO method. Capillary blood glucose samples were collected at 0,15,30,45,60,90-and-120min. Salivary insulin samples were collected at 0,60-and-120min. Subjective appetite ratings (hunger, fullness and desire to eat) were assessed by visual analogue scales (VAS, 100mm) at baseline and 120min.

Eleven subjects (male: 2, female: 9) consumed 50g glucose diluted in 300ml water, tested three times, in different weeks, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Eleven subjects (male: 2, female: 9) consumed 50g available carbohydrates of fir honey diluted in 300ml water, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Eleven subjects (male: 2, female: 9) consumed 50g available carbohydrates of heather honey diluted in 300ml water, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.

Capillary blood glucose responses
Clinically useful change in capillary blood glucose, defined as the restoration of glucose within normal limits during the 2hr glucose tolerance test.
Time frame: 2 hours
Subjective appetite rating
Useful change in subjective appetite using visual analogue scales (VAS, 100 mm, given in the form of booklet, one scale per page) before and 2hr after consumption of six Greek honey grades.
Time frame: 2 hours

Eleven subjects (male: 2, female: 9) consumed 50g available carbohydrates of citrus honey diluted in 300ml water, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Eleven subjects (male: 2, female: 9) consumed 50g available carbohydrates of pine honey diluted in 300ml water, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Eleven subjects (male: 2, female: 9) consumed 50g available carbohydrates of thyme honey diluted in 300ml water, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Eleven subjects (male: 2, female: 9) consumed 50g available carbohydrates of chestnut honey diluted in 300ml water, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
