Study summary

This study determined the glycemic index and glycemic load of six Greek honey varieties

Read the detailed description

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.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Study arms

  • Experimental
    Glucose as reference food

    Eleven metabolically healthy, normal weight subjects (male: 2, female: 9) after 10-14 hr fast, consumed 50g available carbohydrate from D-glucose, tested three times, in different weeks as reference food along with 300ml water. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min. The first glucose sample was taken exactly 15min after the first drink.
