Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aimed to determine the glycemic index and glycemic load of crackers made by different flours (wheat, whole wheat, and 30% sunflower seed flour substitution) and to investigate the effects of these types of crackers on postprandial glycemic responses in healthy humans. Moreover, blood pressure levels and subjective appetite were evaluated.

Glucose as reference food

Eleven healthy, normal body weight adults (male: 4, female: 7) after 12hr fast, consumed 50g available carbohydrates from D-glucose, tested three times, in different visits as reference food; and 50g of available carbohydrates from crackers made by wheat, rye and sunflower flours, 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 samples were taken at baseline, 15, 30, 45, 60, 90 and 120min after food consumption. The first glucose sample was taken exactly 15min after the first bite of food or drink.

Group Type EXPERIMENTAL

Glucose as reference food

Intervention Type OTHER

Eleven healthy, normal weight subjects after 10-14 hours fast, consumed 50g glucose diluted in 300ml water, tested three times, in different visits, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.

Cracker made by wheat flour
