Protein needs during pregnancy

At Creekside OB/GYN of Folsom many patients ask us questions about protein intake. During pregnancy protein requirements increase significantly to support the growth and development of the fetus, as well as to maintain the health of the mother. Proteins are made up of amino acids, which are essential for the formation of new tissues and cells. The recommended daily intake of protein for pregnant women is approximately 70 grams per day, which is higher than the recommended intake for non-pregnant women.

Protein plays a vital role in the development of the fetus. It is necessary for the growth and repair of all tissues, including the developing placenta, amniotic fluid, and fetal organs. During the first trimester of pregnancy, protein requirements are relatively low. However, in the second and third trimesters, the demand for protein increases as the fetus grows rapidly. The increased protein requirement is due to the increased cell division and tissue growth in the developing fetus.

Protein is also essential for the health of the mother during pregnancy. It helps to maintain the strength and integrity of maternal tissues, including the uterus and breasts. It also helps to support the growth of maternal blood volume, which increases significantly during pregnancy. Adequate protein intake during pregnancy can help to prevent gestational diabetes and pre-eclampsia, two common complications of pregnancy.

The quality of protein is also important during pregnancy. Proteins are made up of different combinations of amino acids. Some amino acids are essential, meaning that they must be obtained from the diet, while others are non-essential, meaning that the body can produce them. Animal-based protein sources, such as meat, poultry, fish, eggs, and dairy products, are considered high-quality protein sources because they contain all of the essential amino acids in the right proportions. Plant-based protein sources, such as beans, lentils, nuts, and seeds, are also good sources of protein but may not contain all of the essential amino acids in the right proportions. Therefore, it is essential for pregnant women who follow a vegetarian or vegan diet to consume a variety of plant-based protein sources to ensure they are getting all of the essential amino acids.  It is also important for women to get their protein through food and not protein supplements or powders.

It is also important to note that some types of fish contain high levels of mercury, which can be harmful to the developing fetus. Pregnant women should limit their intake of fish that are high in mercury, such as shark, swordfish, king mackerel, and tilefish. Instead, they should choose fish that are low in mercury, such as salmon, shrimp, and canned light tuna.

In conclusion, protein is essential during pregnancy to support the growth and development of the fetus and to maintain the health of the mother. Pregnant women should aim to consume approximately 70 grams of protein per day from a variety of high-quality sources, including animal-based and plant-based sources.. A balanced and varied diet that meets the increased protein requirements during pregnancy can help to ensure a healthy pregnancy and a healthy baby.
