Pregnancy Nutrition: Protein
The importance of protein during pregnancy
With a vital supporting role for every cell in the body, protein is essential for you and your baby. Learn how many portions to eat as part of a well-balanced pregnancy diet, and why oily fish is an excellent source.
What is protein and why is it important during pregnancy?
Proteins are found in every cell of the body, making up skin, muscles, hair, fingernails and all other tissues. They provide structure to cells and help them function properly, as well as helping cells repair themselves.
During pregnancy, the protein you eat helps your baby grow normally while contributing to other important areas of their development, including:
- Growth and repair of new and damaged tissues
- Making antibodies for their immune system
- Making hormones and enzymes
- Helping muscles function properly
- Transporting oxygen through their blood
Your own need for protein increases during pregnancy too, with a healthy intake needed to support the various changes your body is going through.
Which contains more protein per portion?
Salmon – a 140g portion of grilled salmon contains 33.88g of protein.
Red lentils contain significantly less protein than salmon: around 7.6g per 100g portion.
The building blocks of good health
A good supply of protein during pregnancy enables your baby’s cells to function well from the start. All future growth and development then has a strong foundation to build upon, throughout infancy, childhood and beyond.
