Proteins are like the blocks or bricks of each cell and during pregnancy, when forming a new life, many structures, enzymes, tissues, hormones are being formed and that is why protein requirements increase during this stage, but it must be good quality protein.
The main sources of protein are of animal origin such as eggs, milk, red meat, fish, turkey, chicken. This does not mean that vegetables do not have them. Beans, beans, lentils, and chickpeas have a lot of protein but do not contain all the essential amino acids of animal proteins, so if you prefer to consume vegetables you need to complement them with some cereal such as rice, tortilla, oats or pasta in this way you create protein. high biological value, that is, with all the essential amino acids.
Now, here’s a tip: In a Dutch study they took blood samples from almost 3,000 pregnant mothers and discovered that consuming vitamin B12 could help them have children who cry less. It seems that vitamin B12 helps metabolize amino acids such as homocysteine, which reduces colic and helps regulate sleep cycles, so if you want strong, sleepy babies, sardines, red meat, fortified cereals are the best source of proteins with vitamin b12.
