Breast milk is considered the gold standard for protein intake! Protein is crucial in a baby's diet, and it is important that babies receive the right types of protein.
Breast milk contains 40% casein and 60% whey protein, while cow's milk contains 80% casein and 20% whey. Casein proteins can be harder for babies' tummies to digest, so it's important to look for a formula that includes whey as an ingredient and assimilates into breast milk.
Proteins are made up of amino acids and perform many functions in the body. For example, they are important for the development of body tissue and as enzymes, hormones or transport proteins.
