Brief Summary:

Green tea consumption could lower the risk of type II diabetes, as suggested by epidemiological studies. There is also evidence from intervention studies that green tea can decrease blood glucose levels and contribute to weight loss.

The aim with this study is therefore to examine the postprandial effects of green tea on glycemic index, insulin levels and satiety in healthy individuals after the consumption of a meal.

Condition or disease
Diabetes Type 2 Obesity

Detailed Description:
The study was conducted on 14 healthy volunteers, with a crossover design. Participants were randomized to either green tea or water. This was consumed together with a breakfast consisting of white bread. Blood samples were drawn at 0, 15, 30, 45, 60, 90 and 120 minutes. Participants completed two different satiety scores at the same time intervals.
