You must get the right calories, vitamins, and minerals if you are pregnant.
The calories you need depends on your age, weight, and activity level. Talk with your healthcare provider about the amount that is right for you.
Your healthcare provider will talk to you about the types of foods you need to eat. You may also talk about the kinds of nutrients you will need. You must have some key ones, such as folic acid and iron. You may also need vitamins.
Women who are pregnant or may become pregnant should get 600 micrograms (mcg) of folic acid each day. This mineral is vital during the first weeks of pregnancy, often before a woman even knows she is pregnant. Getting enough can stop neural tube problems, such as spina bifida. It may also stop other birth problems like cleft lip and heart disease. You may also lower your chance of having a miscarriage or stillbirth.
You can get enough by eating foods that have folic acid. You may also want to take a folic acid pill before you get pregnant and through your first trimester. If you are taking a prenatal vitamin that has folate, you do not need to take a folic acid pill.
Foods rich in folic acid are:
Iron is a mineral that helps red blood cells carry oxygen in the body. Pregnant women should get 27 milligrams (mg). Not getting enough can lead to iron-deficiency anemia and other problems.
Good sources are:
Eating foods with vitamin C along with foods that have iron can help you absorb iron. But drinking tea or coffee with these foods can slow absorption.
It can be hard to get all the iron you need from food. Most pregnant women take a prenatal vitamin that has iron. Talk to your healthcare provider about your level. Getting too much is not safe.
You also need calcium. When you do not have enough, your body takes it from your bones. This may cause you to have osteoporosis when you are older.
Good sources are:
If you do not eat dairy products or enough foods that have calcium, talk to your healthcare provider about calcium and vitamin D pills. The body needs vitamin D to absorb and use the calcium.
The body is better getting the nutrients from food during pregnancy. If you are eating healthful foods each day, you may not need a supplement. But many women may benefit from taking a prenatal vitamin. Some may need only an iron or folic acid pill. Others may need an iodine pill if they do not get enough. Talk to your healthcare provider about your eating and lifestyle habits to find out if you need one.
No amount of alcohol is safe. Do not drink until after your pregnancy.
Having one to two cups of coffee or tea per day is fine during pregnancy. Some research has linked high intakes of caffeine (more than 300 mg per day) with having a hard time getting pregnant and a higher rate of miscarriages. Talk to your healthcare provider about how much caffeine you drink.
Seafood is a good source of omega-3 fatty acids. These help with your growing baby's brain. Pregnant women should eat seafood as a normal part of their diet.
Some seafood has high amounts of mercury. This can be harmful to a growing baby. Do not eat fish with a high mercury level. These fish are tilefish, king mackerel, swordfish, albacore tuna, and shark.
Good choices are salmon, sardines, catfish, canned light tuna, and shrimp. These are high in omega-3 fatty acids and low in mercury.
If you do not have a peanut allergy, you may want to think about eating peanuts. It may lower the risk that your child will have a peanut allergy.
Getting sick from unsafe foods could harm you and your growing baby. Here are some tips:
Most artificial sweeteners are safe to use in small amounts, such as acesulfame K (Sunett), aspartame (NutraSweet or Equal), and sucralose (Splenda). More research is needed on saccharin (Sweet’N Low) and stevia. These should not be used.
Getting enough fluids is vital for you and your baby. Try to drink plenty of water each day. Make sure your water does not have too much nitrate. It is found in some private wells. Other drinks, such as juice and soda, also help with hydration. But they are also high in calories and low in nutritional value.
