Thirteen healthy participants (male: 4, female: 9) after 10-14h fast, consumed 50 g available carbohydrates from D-glucose, in different visits as reference food, tested two times; and 50 g available carbohydrates from white bread, tested two times; and 50 g available carbohydrates from cookies containing 0 and 2.5g spirulina, tested once, in different visits, along with 250 mL water. There was a washout period of at least two days between visits. Fingertip capillary blood glucose and salivary insulin samples were taken at 0, 15, 30, 45, 60, 90 and 120 min postmeal. The first glucose and salivary insulin sample were taken exactly 15 min after the first bite of food or drink.
