Diet Modification
Conditions
Brief summary
The proposed project addresses the goal of exploring preschooler's ability to recognize changes in feelings of hunger/satiety based on consuming a snack and a meal (lunch/dinner) that are either based on the usual childcare center fare (control) or are based on lean meats (intervention), which will have a lower glycemic index.
Interventions
Replacement of typical meal/snack with lean pork containing meal/snack

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Glycemic load of diet | 6 study days | Estimated intake of glycemic load of meals and snacks consumed. Plate-waste method will be used to calculate total energy, GI, GL consumed at each meal and snack using disaggregated intake (in grams) and analysis using Nutrient Data System for Research (NDS-R) software. |
| Hunger/Satiety self-reported on 4-point scale | 6 study days | Self-reported feelings of hunger or fullness using: 1 = Very hungry, 2 = A little hungry, 3 = A little full, 4 = Very full |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Executive function: focus and short-term memory | 6 study days | Using the track-it game, children respond to visual cues. |
| Executive function: memory and focus | 6 study days | Using KRISP, children respond to visual cues to assess focus and short-term memory |
| Blood pressure | 60 minutes after the meal. | Measured blood pressure 60 minutes after the meal. |
| Executive Function: Concentration | 6 study days | Using the happy-sad game, children sort small playing cards with happy or sad faces on them to align with the verbal cue of the researcher, or to put down the opposite card. |
| Executive Function: Focus and Concentration | 6 study days | Using the peg it game, children are asked to use a small wooden hammer to tab the table surface. First, they repeat how many tabs the researcher demonstrated (1 or 2), then they are asked to tab the opposite, so if the researcher tabs once, they tab twice and when the researcher tabs twice, they tab once. |
| Blood glucose | 6 study days | Blood glucose concentration 60 minutes after the meal. Measured using finger-stick and glucometer reading. |
