Skim milk in infant feeding

Area of Science:

• Pediatrics
• Infant Nutrition
• Growth and Development

Background:

• Infant feeding practices significantly impact growth and body composition.
• Evaluating the nutritional adequacy of different infant formulas is crucial for healthy development.

Purpose of the Study:

• To compare the effects of a standard infant formula (Similac) versus a modified skim milk formula (Formula 305) on infant growth and body composition.
• To assess energy intake, weight gain, length gain, and changes in skinfold thickness in infants fed different formulas.

Main Methods:

• A controlled study involving 94 infants aged 112 days, with 88 completing 56 days of observation.
• Infants were fed either Similac (67 kcal/100 ml) or Formula 305 (36 kcal/100 ml) alongside strained foods.
• Measurements included food intake, weight gain, length gain, and skinfold thickness (triceps and subscapular).

Main Results:

• Infants fed Similac had significantly greater energy intake and weight gain than those fed Formula 305.
• Length gain was similar between the two feeding groups.
• Skim milk-fed infants showed a 25% decrease in skinfold thickness, suggesting mobilization of body fat stores.

Conclusions:

• Standard infant formula (Similac) supports greater energy intake and weight gain compared to the modified skim milk formula (Formula 305).
• The modified skim milk formula may lead to a reduction in infant body fat stores.
• Further research may be needed to optimize skim milk-based formulas for infant nutrition.
