Prenatal Nutrition

Healthy eating plays a very important role in a healthy pregnancy. You need to eat foods from a variety of sources to make sure you get all the vitamins, minerals and nutrients you and your developing baby need. Eating well will also help you feel better, give you more energy and help you gain a healthy amount of weight. It will also contribute to your baby’s healthy growth and development.

Little feet Important Facts

Know what you need

During your second and third trimesters of pregnancy, you need a few more calories each day to support the growth of your baby. One extra snack is often enough. For example, have an apple or a pear with a small piece of cheese as an afternoon snack. Follow Eating Well with Canada’s Food Guide to eat the amount and type of food that is right for you and your baby.

Fruits and vegetables are a must!

Pregnant women need fruits and vegetables every day. Brightly coloured vegetables and fruit contain more of the kinds of vitamins you and your baby need. You should eat at least one dark green and one orange vegetable each day. Make sure your fruits and vegetables are prepared with little or no added fat, sugar and salt, and choose vegetables and fruit more often than juice.

Grain products are important

You need to include grain products as part of your daily diet. This includes foods like bread, rice and pasta. Try to choose grain products that are lower in fat, sugar and salt, and look for the “whole grain” variety since at least half of your daily grain intake should be whole grain.

Have milk and milk alternatives for strong bones

Milk and alternatives are important for your growing baby. Opt for the low-fat variety, which will give you the high quality protein, calcium and vitamin D you need but with less of the fat and calories. Have skim, 1% or 2% milk every day and go for lower fat varieties of yogurt and cheese. Drink fortified soy beverages if you do not drink milk.

Include meat and meat alternatives

Eating meat and alternatives each day will help you and your baby stay healthy. Choose lean (less fatty) meats and meat alternatives—dried peas, beans, tofu and lentils—made with little or no added fat or salt. Fish is also important and should be eaten each week. But choosing which fish to eat, and how much, can be complicated.

Visit Health Canada’s Web site to find out how to choose fish that are low in mercury so that you and your baby can take advantage of the benefits of eating fish while minimizing the risks from mercury.

Next Steps

Aim for three meals a day with healthy snacks in between. Check out Canada’s Food Guide to see how many servings of each food group you need each day.

Take a multivitamin every day.

Make sure it has 0.4 mg of folic acid and 16 to 20 mg of iron. A health care provider can help you find the multivitamin that is right for you.
