Are eggs a good source of protein?

1. Protein content:

  • Indeed, eggs are an exceptional source of protein, containing approximately 6 grams per medium-sized egg.
  • This protein is of high quality and is considered a complete protein, which means that it provides the nine essential amino acids that our body cannot produce on its own.
  • Additionally, eggs contain all the necessary non-essential amino acids, making them a complete protein source.

I knew it? The protein content of an egg is divided between the yolk and the white. The white, also known as albumin, constitutes around 60% of the protein content, while the yolk provides the remaining 40%.

2. Bioavailability:

In addition to their protein content, eggs offer another advantage when it comes to absorption. Egg protein is highly bioavailable, meaning it is easily digested and absorbed by the body.

Protein source Protein digestibility corrected amino acid score (PDCAAS) (%)
Eggs 100
whey protein 92
Beef 80

The protein digestibility-corrected amino acid score (PDCAAS) is a measure that determines the quality of a protein based on its amino acid composition and digestibility. This score ranges from 0 to 100%, with a higher score indicating better protein quality.

Compared to other protein sources, such as whey protein and beef, eggs have an exceptional PDCAAS score of 100%. This means that the protein in eggs is effectively used by the body, making them an excellent choice for meeting protein needs.

Eating Eggs for Eye Health

Eggs are not only a versatile and delicious food, but also offer a variety of beneficial nutrients to maintain healthy eyes. Facing vitamins, minerals and antioxidants, eggs can contribute to the general wel l-being of the view. Some key nutrients found in eggs and their possible benefits are listed below:

  • Luteine and Zeaxantine: These antioxidants are naturally present in eggs and have been related to the reduction of macular degeneration associated with age (DMAE), one of the main causes of loss of vision in older adults. Studies suggest that greater lutein and zeaxantine consumption is associated with a lower risk of DMAE.
  • Vitamin A: Eggs are a good source of vitamin A, essential to maintain adequate vision. Vitamin A plays a crucial role in rodopsin production, a retina pigment that contributes to night vision and with little light.
  • Omega-3 fatty acids: Although eggs are not an important source of omega-3 fatty acids compared to fish or certain nuts, they contain a small amount. Omega-3 fatty acids contribute to the general health of the eyes and can help prevent ocular dryness and age-related ocular diseases.

“Incorporating eggs into your diet can be a tasty and nutritious form of supporting your ocular health. The presence of luteine, zeaxantine, vitamin A and omega-3 fatty acids in eggs makes them a valuable complement to a balanced diet.”
