Postprandial differences in glucose and insulin levels per formula.

	Cow’s Milk Protein Formula	Soy Protein-Based Formula	Lactose-Free Formula	p Value
Glycemic index	21.5 ± 21.7	29.1 ± 17.2	21.5 ± 14.5	0.21
Peak glucose level (mg/dL)	101.8 ± 9.1	111.5 ± 13.7	105.8 ± 12.1	0.001 *
Glucose changes from baseline (mg/dL)	13.1 ± 7.2	21.7 ± 11.5	16.3 ± 10.3	0.006 *
Peak insulin level (mU/mL)	12.1 ± 6.5	12.1 ± 7.0	10.8 ± 5.5	0.45
Insulin change from baseline (mU/mL)	5.0 ± 5.7	5.0 ± 5.2	3.4 ± 6.4	0.52

Values are expressed as the mean ± standard deviation. * Difference between soy-based formula and both cow’s milk protein-based and lactose-free formulas.
