Evaluation of the Glycemic Index in 4 Dairy Beverages.

Study Overview
=================
Brief Summary
-----------------
The objective of the study is to evaluate the glycemic index and glycemic load of 4 chocolate milk drinks.

Detailed Description
-----------------
Subjects will make a total of 5 visits. Four visits where they will drink a chocolate milkshake at each visit. In the other visit they will take glucose, as a comparator product. Due to the low amount of sugars in the shakes, subjects will drink the equivalent of 25g of glucose. At each visit subjects will have to come fasting, and samples will be collected at 9 different times.
