The Power of Protein
When you become pregnant, your protein needs increase by 30 percent. Protein can be found in both animal and plant foods, which makes it easy for both meat-eating and vegetarian women to get all of the protein they need. If you are a vegan, as long as you eat a wide variety of plant foods including whole grains, cereals, legumes, and soy products at each meal, you too should have no problem consuming all of the protein you need for a healthy pregnancy.
Protein is considered a macronutrient because it provides the body with energy, or calories. Protein is part of every cell in the body. Your body requires a constant supply of protein to repair body cells as they wear out. During pregnancy, you need protein to make new cells. Your body's tissues are all unique because of the differing amino acid patterns in their proteins. Amino acids are the building blocks of proteins. Your body uses about twenty different amino acids to make body proteins. Of those, nine are considered essential-your body cannot make them, and you must get them from the foods you eat. The others are considered nonessential amino acids because your body does make them as long as you consume enough essential amino acids and enough calories each day. Animal foods such as meat, poultry, fish, eggs, milk, cheese, and yogurt contain all nine essential amino acids. These foods are said to contain "complete proteins" or "high-quality proteins." Plant foods, on the other hand, contain essential amino acids, but not all nine together. These sources are said to be "incomplete proteins."
Fact: Soy is the exception to the incomplete protein rule. Soy is the only plant food that is a complete protein and contains all nine of the essential amino acids.
Gone are the days when vegans were instructed to eat foods in special combinations at each meal to make sure they were getting the right mix of essential amino acids to make proteins. Instead, vegans need only make sure they are eating a balanced diet that includes a wide variety of plant foods and that provides enough calories each and every day. If you are a vegan, this eating plan will ensure you are receiving all of the essential amino acids in needed amounts each day to make the proteins that you body needs. It is more important to think about your total day's intake rather than each meal individually.
Omega-3 Essential Fatty Acids
Fats are made up of two types: saturated and unsaturated. Unsaturated fats include monounsaturated and polyunsaturated. Two polyunsaturated fatty acids, linoleic acid (omega-6) and alpha-linolenic acid (omega-3), are considered essential because the body cannot make them. Omega-3 fatty acids are essential fats that can be very heart-healthy as well as vital to the development of a baby's brain and nerves. They are also vital to eye development, growth, and vision. In addition, researchers are studying the question of whether omega-3 fatty acids are helpful in preventing preterm labor and possibly protecting against postpartum depression.
Sources of Omega-3 Fatty Acids
Vegetarians are advised to consume omega-3 fatty acids from eggs as well as from plant-based ingredients such as canola oil, soybean oil, walnuts, walnut oil, ground flaxseed (which you can add to baked goods or smoothies), flaxseed oil, soybeans, wheat germ, and other nuts and seeds. For vegetarians who consume fish, fatty fish such as salmon, mackerel, herring, trout, tuna, and sardines also supply omega-3 fatty acids. If you consider a fish-oil supplement as another means of getting Omega-3 fatty acids, beware that some (those that come from the liver of the fish) can contain high levels of vitamin A, which in excessive doses may cause birth defects. Even though pregnant women need to be careful of how much fish and the type of fish they eat, keep in mind that not all fish contain toxic levels of mercury. Eating a few servings a week of allowed fish can help ensure your intake of Omega-3 fatty acids.
