When it comes to protein, it is important to consume adequate amounts of foods that provide sufficient amounts of protein-derived amino acids such as red meat, chicken and fish. For vegetarians, it is important to combine different types of vegetable proteins to maintain adequate protein intake. Types of foods that are considered a good source of protein include lentils, all types of beans, seeds, peas, soybeans and grains.
Dairy products such as milk, cheese and yogurt provide important nutrients and especially calcium essential for the body and the pregnancy. It is important to avoid unpasteurized dairy products because of possible listeria infection, but this is nearly eliminated in pasteurized products.
