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.
child 2-5 years old
Parents of at least one child aged 2-5 years old
Parents can communicate in English.
Parents in households who do not have a cultural/ religious reason to abstain from to consuming pork
Food allergies
Taking medication that affects food intake (such as stimulant medications),
Children with diabetes or impaired glucose control.
Children with digestive disease (such as Crohn's)
Crossover
Low glycemic index diet
Other interventionReplacement of typical meal/snack with lean pork containing meal/snack
Glycemic load of diet
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
Self-reported feelings of hunger or fullness using: 1 = Very hungry, 2 = A little hungry, 3 = A little full, 4 = Very full
Blood pressure
Measured blood pressure 60 minutes after the meal.
Blood glucose
Blood glucose concentration 60 minutes after the meal. Measured using finger-stick and glucometer reading.
