History and current status of infant formulas

Abstract
Formulas that approximate the composition of human milk are widely used as the sole source of nutrients for infants during the first months of life. Such formulas contain milk, soy, or meat proteins, or protein hydrolysates together with those forms of fat, carbohydrate, vitamins, and minerals shown to be bioavailabile to the infant. Legislation concerning nutrient composition and quality assurance of products labeled as infant formulas has been enacted by Congress. Governmental and industrial standards also help to assure microbiological safety and stability. Problems of nutrient composition and adverse reactions have occurred during the evolution and development of infant formulas. Problems concerning nutrient deficiency are now almost unknown, but adverse reactions of individuals to specific formula ingredients continue. Accurate information on composition and related nutritional properties of infant formulas is essential for their effective use and for avoidance of undesirable complications.
