Low protein formula

The faster weight gain of formula fed infants compared with breastfed infants is thought to be due to the significantly higher protein intake, which is 40-50% higher compared to that of breastfed infants. A higher protein intake has a range of metabolic consequences which can lead to obesity, including higher plasma levels of branched chain amino acids, IGF-1, and insulin.

The primary limiting factor in low protein formulations is the need to ensure the required level of amino acids. Lowering the total protein content places higher demands on the quality of the protein ingredients in the formulation. 

Alpha-lactalbumin is the major protein in human milk and has an exceptionally high content of essential amino acids, making it a key ingredient in low protein formulations. Arla Foods Ingredients has developed two ingredients rich in alpha-lactalbumin making it possible to optimise the protein level in a formula and simultaneously meeting the requirements for essential amino acids.
