A Pooled Analysis of Growth and Tolerance of Infants Exclusively Fed Partially Hydrolyzed Whey or Intact Protein-Based Infant Formulas

Table 1

Nutrient composition of infant formulas.

Composition	Units	CMF	PHF-W
Energy	kcal/100 mL	67	67
Carbohydrate	g/100 kcal	11	11.2
Fat	g/100 kcal	5.3	5.1
Protein	g/100 kcal	1.8	2.2
Whey:Casein	- - -	70:30	100:0

Formulas tested in different trials had consistent energy and macronutrient composition but may have varied slightly on micronutrients. The exception is one PHF-W study which had a protein content of 2.4 g/100 kcal [9]. None of the formulas used included probiotics. One study of PHF-W included 4 g galactooligosaccharides/L formula [5]; no other study formulas contained a prebiotic.
