Arms Assigned Interventions
Experimental: Brown Seaweed Lemon Tea
Single administration of lemon tea containing 500 mg of brown seaweed powder and 50 g of sucrose
Dietary Supplement: Reduction of glycemic index of ingested foods
Oral administration of the experimental lemon tea powder(56.1 g) and the placebo lemon tea powder (55.6 g) dissolved in water. Each participant will receive both treatment in a cross-over protocol design during 2 visits separated by a 2-weeks period. The day before both intervention, participants will consume a standardised meal for the supper.
Other Name: InSea2
Placebo Comparator: Placebo lemon tea
Single administration of placebo lemon tea containing 50 g of sucrose
Dietary Supplement: Reduction of glycemic index of ingested foods
Oral administration of the experimental lemon tea powder(56.1 g) and the placebo lemon tea powder (55.6 g) dissolved in water. Each participant will receive both treatment in a cross-over protocol design during 2 visits separated by a 2-weeks period. The day before both intervention, participants will consume a standardised meal for the supper.
