Introduction

Image of a man ebracing a pregnant womanOne of the most important ways to protect your health during pregnancy is to eat a healthy diet. Eating well, combined with taking a daily multivitamin and minerals (i.e. Folic acid, calcium) can give a woman the nutrients she needs to feel good, have energy, and support a healthy pregnancy.

Healthy Eating Guidelines for Pregnancy

Weight gain during pregnancy


Gaining weight is a natural part of pregnancy. How much weight you should gain depends on your weight (or body mass index- BMI) before you became pregnant. Visit the Pregnancy Weight Gain Calculator to learn more.

Foods to avoid during pregnancy


Most foods are safe to eat in pregnancy. However, there are some foods that are best to avoid due to the risk of certain infectious diseases that can be dangerous to your baby:

Healthy Eating Guidelines for Food Safety in Pregnancy

For more information, please see Health Canada's website on food safety during pregnancy.

Caffeine


Pregnant women should limit the amount of caffeine they consume to no more than 300 milligrams of caffeine per day from all sources. A small (250 ml or 8 oz) cup of coffee contains approximately 100 mg depending on the coffee. The same sized cup of tea or pop contains about 50mg. Too much caffeine increases your risk of miscarriage and of having a low birth weight baby.

Eating Fish in Pregnancy


Pregnant women should choose low mercury seafood (i.e. salmon and shrimp) over higher mercury varieties (i.e. tuna). Pregnant women should ensure that their food is obtained from reputable establishments; stored, handled, and cooked properly; and consumed within a couple of days of purchasing.

Herbal Products


Many women take herbal products and natural remedies. These products are not regulated by the government. Some may be safe; however, others may contain ingredients that may be harmful to you and your baby during your pregnancy. Before taking any herbal or natural product, please speak to your doctor or pharmacist about them.

Vitamins and Minerals in Your Pregnancy


Folic Acid

How do you make sure you get enough folic acid?

You can get some folic acid from eating certain foods.

Examples of foods that have a large amount of folic acid are:


However, it is hard to get enough folic acid from your diet. It is better to take a vitamin that contains folic acid.

How much Folic Acid should be in your vitamin supplement?

Most woman should take a vitamin containing 1.0 mg of folic acid per day, for at least two to three months before conception and throughout pregnancy and the postpartum period (4-6 weeks and as long as breastfeeding continues).

If you are at higher risk of having a child with neural tube defects, then talk to your doctor about how much folic acid you need.

For more information about Folic acid please refer to the links below:

Calcium and Vitamin D

Health Canada sets the recommended daily allowance of vitamins and minerals during pregnancy. Most women who eat a healthy, balanced diet will get enough Calcium and Vitamin D from food that they eat. 

The recommended total daily intake of calcium and Vitamin D for pregnant women (i.e. from either food or supplements or a combination of both) is:
