Summary

This study investigated the effects of three doses of spirulina in glucose beverages on postprandial glycemic responses, arterial blood pressure, and subjective satiety.

Detailed description

This study aimed to determine the effects of three different doses (4, 6 and 8 g) of spirulina in glucose beverages on postprandial glycemic responses, blood pressure, and subjective appetite responses in healthy young adults.

Conditions

• Potential Abnormality of Glucose Tolerance
• Appetitive Behavior
• Blood Pressure

Interventions

Type	Name	Description
OTHER	Glucose as reference food	Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose diluted in 250ml, tested two times, in different visits, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
OTHER	Beverage containing 4g spirulina	Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose and 4g spirulina diluted in 250ml, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
OTHER	Beverage containing 6g spirulina	Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose and 6g spirulina diluted in 250ml, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
OTHER	Beverage containing 8g spirulina	Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose and 8g spirulina diluted in 250ml, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
