Breastfeeding And Your Diet

What is a healthy diet while breastfeeding?

A healthy diet is a meal plan that provides the amount of calories and nutrients you need while you are breastfeeding. Your body needs extra calories and nutrients to keep you healthy and support milk production. A healthy diet includes a variety of foods from all the food groups.

What are some guidelines I should follow while I am breastfeeding?

  • Increase your calories. During breastfeeding, your body needs about 500 extra calories per day. You may want to try eating smaller meals more often throughout the day to meet your needs. A dietitian can tell you how many total calories you need to eat each day and help you create a healthy meal plan.

  • Drink plenty of liquids. You need about 8 to 12 cups of liquid each day to prevent dehydration and keep up your milk supply. You may want to try drinking a beverage each time you breastfeed to help you get enough liquid. Drink liquids that do not contain caffeine, such as water, juice, and milk.

  • Get enough calcium and vitamin D. Breastfeeding women who are 19 or older need 1000 mg of calcium each day. Those who are younger than 18 years need 1300 mg of calcium each day. You can get calcium from dairy foods such as milk, yogurt, and cheese. Sunlight helps your body make vitamin D. Women who are not exposed to the sun very much may have low vitamin D levels. While you are breastfeeding, you should get 5 micrograms of vitamin D each day. Fish oil is a good source of vitamin D. Milk and other foods are also fortified with vitamin D. Talk to your caregiver about supplements if you do not eat foods with calcium and you do not get much sunlight.



  • Get enough nutrients if you are on a special diet. Women who do not eat certain foods may not get enough of some nutrients. For example, women who follow a vegan diet do not eat animal products, such as meat, eggs, and dairy products. Animal products provide important nutrients, such as protein and vitamin B12. You may not be able eat dairy products if you are lactose intolerant. Dairy products are high in calcium and vitamin D. Talk to your caregiver if you follow a special diet and think you may need a supplement.

Do the foods I eat affect my baby?

The food you eat usually will not affect your baby. Most women find they can eat any type of food without causing a problem for their baby. If you think something you ate affected your baby, do not eat the food that may have caused the problem. Talk to your caregiver if you think your baby has a food allergy or sensitivity. If your baby does have a food allergy, you can still breastfeed.

What should I avoid or limit while I am breastfeeding?

  • Limit or avoid alcohol. Alcohol passes from your breast milk to your baby. If you choose to drink alcohol, breastfeed your baby before you drink the alcohol. Do not breastfeed your baby for at least 2 hours after you have 1 drink. One drink of alcohol is 12 ounces of beer, 4 ounces of wine, or 1½ ounces of liquor.

  • Limit caffeine. Caffeine can also pass into your breast milk, so you may want to limit caffeine. Caffeine is found in coffee, tea, some sodas, energy drinks, and chocolate. Ask your dietitian how much caffeine you can have each day.

  • Ask about herbal teas and supplements. You may need to limit or avoid certain herbal teas or supplements. Talk to your caregiver about the types of herbal teas and supplements that are safe for you to have.

  • Limit fish that contain mercury. Mercury is found in almost all types of fish and shellfish. Each week, you may eat up to 12 ounces of fish or shellfish that have low levels of mercury. These include shrimp, canned light tuna, salmon, pollock, and catfish. Eat only 6 ounces of albacore (white) tuna per week. Albacore tuna has more mercury than canned tuna. Do not eat shark, swordfish, king mackerel, or tilefish.

Can I try to lose weight while I am breastfeeding?

You may lose weight naturally by following a healthy diet while you are breastfeeding. This can happen because your body needs more calories while you are breastfeeding. This weight loss may not happen for all women. If you want to lose weight, do not cut down your calories too much or lose weight too quickly. This may cause you to decrease your milk supply or decrease your levels of certain nutrients. Most women can safely lose up to 2 pounds a week without affecting their milk supply or health.
