Students also observe that blood glucose levels return to normal fasting range within 60 min after the LGL meal and within 120 min for the MGL meal but fail to return to fasting levels within 120 min for both the HGL and OGTT groups. At 60 min, blood glucose levels peaked for the OGTT group (151 8.4), whereas the HGL, MGL, and LGL groups showed a decline from 30-min levels. Every spring, you have congestion and a runny nose. Discussion is always vibrant, and students are encouraged to use both laboratory computers and personal devices to gather information pertinent to the conversation. Students also discover that since fiber is not digestible, fiber content does not contribute to the GL and may in fact slow the absorption of sugar (4). Although fasting is typically 1012 h, we felt it necessary to allow students to eat something before morning classes as all laboratories meet in the afternoon. Students could also be required to work in groups to develop original, testable hypotheses and design an appropriate experiment to conduct. 47.3 1.
