Most mothers do not need to change their healthy diet while breastfeeding. "Good" and "bad" foods for breastfeeding are often culturally, rather than physiologically, determined. For example, Indian moms are told that garlic will be beneficial to breastfeeding, while American moms are cautioned to avoid this food.

That being said, if you have a family history of allergy, including asthma and atopic dermatitis, you may want to avoid dairy products, as well as any other foods you are allergic/sensitive to while breastfeeding. Be sure to speak with your health care provider when making dietary changes, to be sure that all your nutritional needs are being met.

Some babies are indeed sensitive to foods in their mom's diet, but I would caution against arbitrarily limiting your diet unless you have reason to suspect a particular food is bothering your baby. If your baby shows feeding-related sensitivities, this is most often due to a foreign protein in mothers' milk. In this case, try eliminating the food, which is the most likely culprit for at least one week. (Remember to read all labels.)If you do not see an improvement, you can add this food back into your diet and try another food to see if it is the offender. Keeping a journal with foods eaten and your baby's behavior may be helpful.

Dairy products in a mom's diet can cause sensitivity. (This sensitivity to milk protein is not at all related to lactose intolerance.) Other foods you may consume that your baby may show sensitivity to include eggs, peanuts and other nuts, wheat, soy, corn, tomatoes, onions, cabbage, berries, nuts, spices, pork, seafood, citrus fruits and juice and chocolate.

Basically, while breastfeeding, it's best to eat a nutritious, well-balanced diet of at least 1800 calories per day. Choose foods that are close to their natural state, making sure to include at least five servings of fruits and vegetables each day. Try to go light on processed foods. If you find it difficult during your busy day to eat as nutritiously as you should, cut up some fruits and vegetables the night before, or ask your partner to help you. Having nutritious, easy-to-grab snacks is important for new moms, who are often too tired to prepare anything for themselves. Foods that constitute a good diet for life, also make a good diet for breastfeeding. My best wishes!
