Breastfeeding Diet

Breastfeeding women should eat a varied, balanced diet that is rich in whole grains, fruits, vegetables, and lean proteins. In general, there is no need for a special diet, though there are topics to consider.

How Much Do I Need to Eat While Breastfeeding?

If you are exclusively breastfeeding, you will need an extra 400-500 calories per day above what was needed to maintain your pre-pregnancy weight. During the first few months, your body will be able to use the fat you stored during pregnancy to meet part of this requirement. Rather than focusing on how many calories you are eating, let your body be your guide, and eat when you are hungry.

What Should I Eat While Breastfeeding?

What you eat is as important as how much you eat. You may be able to get away with an extra cookie or two while breastfeeding, but be sure to fill up on nutrient-dense foods first. Your baby will get all the nutrients she needs from your breast milk, but you want to make sure there are enough nutrients left for you to use too. If you do not consume enough calcium, for instance, your body will take it from your bones, increasing your risk of osteoporosis.

Additional Considerations


Because of the extra calories that it requires, breastfeeding will help you to return to your pre-pregnancy weight sooner. However, your focus should be on healthful eating, not dieting. If you diet during breastfeeding, you are putting yourself and your baby at risk. If you find that you are having a hard time losing the weight you put on while pregnant, talk to a registered dietitian. He can create a personalized eating plan.

Fluid Needs

While breastfeeding, it is important to drink enough fluids to make enough milk. Many women find that they are thirstier than usual, especially when they first start breastfeeding. Have at least eight glasses of water a day, as well as drinking healthful drinks such as low-fat milk and 100% juice.


You may choose to supplement your diet with a multivitamin, although this is not a substitute for eating a balanced diet. Check with your doctor before taking any supplements.


Most experts recommend that you should avoid alcoholic beverages during breastfeeding. Alcohol passes into your milk in the same concentrations as it is in your bloodstream. If you do choose to have an occasional drink, try to time it so that it’s right after a feeding.


For most women, having one or two cups of coffee or tea per day is fine. If you find that your baby is irritable or having difficulty sleeping, try eliminating caffeine for a couple of days and see if it makes a difference.


Fish and shellfish are an important source of lean protein and omega-3 fatty acids. However, seafood also contains mercury, which in high amounts, can be detrimental to your developing baby. While breastfeeding you should consume up to 12 ounces of fish per week, but avoid fish that contain high levels of mercury, specifically: tilefish, king mackerel, swordfish, albacore tuna, and shark. Good choices include salmon, sardines, canned light tuna, and shrimp. These are both high in omega-3 fatty acids and low in mercury.

Spicy or “Gassy” Foods

You may have heard that you should avoid spicy or “gassy” foods; however, this is only true if they are a problem. If your baby is unusually fussy, try eliminating potential trigger foods from your diet for a 24-hour period and see if it makes a difference.
