Overview
The purpose of this study is to determine whether continuous glucose monitoring is sensitive to quantifying the glucose response related to consumption of a starchy vegetable (potato) in combination with or separate from consumption of herbs and spices at the same meal.
Description
This is a pilot study which will enroll a maximum of 10 participants. There will be 3 different food entree preparations that participants will consume (1 entree per day within the 10 day period). The order in which participants eat the different entrees will be randomized. The 3 different food entree preparations are as follows: 1) prepared potato entree with no herbs and spices, 2) prepared potato entree paired with herbs and spices, 3) prepared potato entree with herbs and spices consumed at a subsequent meal.
Following enrollment, participants will be randomized to the order of entree preparation types and provided all of the entrees with the instructions for food preparation and order of consumption noted when they arrive at the scheduled study visit. The entrees will be standardized for caloric content, composition, and preparation method. Post-consumption glucose responses will be recorded by continuous glucose monitors, which will be provided to participants at the first study visit.
