Summary
For infants aged 6-12 months, iron-fortified formulas complement beikost well. Cow milk, however, poses risks due to high protein, electrolytes, and potential blood loss, making it unsuitable.
Area of Science:
- Pediatric Nutrition
- Infant Dietetics
- Clinical Nutrition
Background:
- Older infants consume significant nutrients from beikost (foods other than milk/formula).
- Infant milks and formulas should balance beikost nutrient intake without overwhelming infant excretory capacity.
- Contemporary infant nutrient intake data is essential for dietary recommendations.
Purpose of the Study:
- To evaluate the total nutrient intake of 6- to 12-month-old infants.
- To assess the suitability of different milk/formula options when combined with beikost.
- To determine if current infant formulas meet nutritional needs without excessive renal solute load.
Main Methods:
- Analysis of contemporary nutrient intake data from beikost for 6- to 12-month-old infants.
- Calculation of total nutrient intake based on beikost consumption plus various milk/formula options.
- Comparison of nutrient profiles and renal solute load for different feeding regimens.
Main Results:
- Infants consuming beikost plus iron-fortified formulas show satisfactory nutrient intake.
- Cow milk consumption with beikost leads to excessive protein and electrolyte intake.
- Cow milk feeding results in an unduly high renal solute load for infants.
- Cow milk is associated with occult intestinal blood loss in infants.
Conclusions:
- Iron-fortified formulas are appropriate for older infants (6-12 months) alongside beikost.
- Cow milk is not recommended for infants aged 6-12 months due to nutritional imbalances and health risks.
- Dietary recommendations for infants must consider the interaction between beikost and milk/formula intake.
