Nutrition During Pregnancy

Not pregnant yet? Visit the Before Pregnancy section to find out more about food and nutrition before pregnancy. 

The food you eat during your pregnancy will support the development of your growing baby and help you feel your best. Eating a variety of foods will help you get all the important nutrients you and your growing baby need.

When you are pregnant, the amount of vitamins and minerals you need increases. A prenatal multivitamin and mineral supplement helps you get the extra nutrients you and your baby need. Your daily multivitamin should have 0.4 milligrams (mg) of folic acid and 16 to 20 mg of iron. Chewable supplements or gummies may not contain adequate amounts of iron. 

Healthy eating is more than the foods you eat and looks different for everyone:

  • Be mindful of your eating habits.
  • Take time to enjoy your meals.
  • Eat with others when possible.
  • Limit distractions during mealtime.
  • Plan your meals and snacks.
  • Include culture, food traitions, and taste preferences as part of your eating pattern.
 

Eat a variety of foods each day:

  • Eat regular meals with snacks in between. Try making half your plate vegetables and fruit.
  • Eat a variety of vegetables and fruit (fresh, frozen and canned), whole grain and protein foods (e.g., fish, meat, poultry, milk, yogurt, cheese, eggs). Choose protein foods that come from plants (e.g., beans, legumes, nuts, seeds, tofu) more often. Visit Canada's Food Guide for more information. 
  • Drink water regularly to stay hydrated.
  • Choose milk or unsweetened fortified plant-based beverages daily. Soy beverages usually have more protein than most other plant-based beverages.
  • Include fats that support growth and development (e.g., fatty fish, nuts, seeds, non-hydrogenated margarine, avocado, vegetable oil-based salad dressings, or vegetable oils such as canola and olive) daily at your meals and snacks.
  • Fish can provide important nutrients that support a healthy pregnancy and breast milk production. However, some types of fish contain mercury, which can harm your baby’s brain development. Choose fish low in mercury such as canned light tuna. 2
  • Read nutrition labels to choose items with lower saturated fats, sodium, and sugar.
  • Pregnant people need more food in the second and third trimesters and while breastfeeding. This means you may need an extra nourishing snack or small meal.  
  • Being mindful of how you eat is also important during pregnancy. Take time to enjoy eating and limit distractions during meals and snacks. Include culture and food traditions into your meal planning.
  • If you are pregnant or planning to become pregnant, the safest choice is not to drink alcohol.

Food Safety and Pregnancy

Food safety is especially important during pregnancy. The hormones in pregnancy change the immune system, making it more likely for a pregnant woman to get a foodborne illness (food poisoning). Even if you don’t feel sick, the pathogen that cause poisoning can cause serious harm to your baby. Take extra care with handling food when you are pregnant.

Caffeine and Pregnancy

Too much caffeine is not good for you or your baby. Health Canada recommends that all women who can become pregnant, are pregnant or breastfeeding have no more than 300 mg of caffeine a day. Be aware of how much caffeine you are getting from coffee, tea and other foods and beverages. Drinking water, milk or unsweetened fortified plant-based beverages are better choices.

Changes in Your Body During Pregnancy

During the 9 months of pregnancy your body goes through many changes. Changes in body shape and weight are needed to support a healthy pregnancy. Choosing a variety of foods, eating regularly throughout the day, and participating in joyful movement helps pregnant people feel their best. Approach your body changes with kindness.
