Every human body needs amino acids (protein building blocks) to carry out a host of important functions including protein synthesis - the creation of proteins within the body to maintain optimal health, growth, development, and function throughout life.1
Luckily, our body produces amino acids on its own — with the exception of essential amino acids (the necessary nine). The only way our body gets them is through the food we consume.2
Protein quality - how well the body is able to use a protein - can be assessed based on the amino acid composition, how well it matches the body requirements, and how easy it is to digest.4
Egg white protein has all the nine essential amino acids the body needs and it’s highly digestible, making it one of the protein sources with the highest protein quality score according to multiple protein quality rating methods.5-8
Egg white protein contains amino acids important for muscle growth and maintenance like leucine, lysine, and methionine, which are typically present in lower quantities or deficient in other protein sources like plant proteins.6, 27, 28
Egg white protein is actually a group of 150+ individual proteins working together to give egg white its unique nutritional and functional properties.12
Many egg white proteins can provide benefits beyond fulfilling nutritional requirements that can be important for human health and disease prevention.9-11
Research studies have reported that egg white proteins and their components (protein fragments called peptides) can exhibit antioxidant, antihypertensive, anti-inflammatory, anti-diabetic, immunomodulatory, anticancer, and antimicrobial activities as well as ability to improve bone health.15-23
These properties are possible not only due to the amino acid composition present in egg white but how they are particularly sequenced within each protein.13, 14
Every cell in the human body contains protein, meaning it’s critical for our bodies to:4
That’s why eating patterns that prioritize protein have been known to:1, 31-37
