Your nutrition should be a priority from the time you become pregnant, throughout your pregnancy, and breastfeeding. Dr. Hill can review information about proper pregnancy nutrition for during pregnancy and after at your prenatal care appointments. The food that you eat has a direct impact on your breast milk and affects your baby’s overall well-being. We have gathered a list below of the foods that you should consider reducing while breastfeeding.
According to the Centers for Disease Control and Prevention (CDC), abstaining from alcohol is the safest option during breastfeeding. However, an occasional drink is likely safe, if you’re cautious about the amount and timing  It is important that the alcohol is out of your system before you breastfeed so that this does not get passed along to your baby.
Avoid drinking more than 2 to 3 cups (16 to 24 ounces) of caffeinated drinks a day. Caffeine in your breast milk might agitate your baby or interfere with your baby's sleep. 
Seafood can be a great source of protein and omega-3 fatty acids. Most seafood contains mercury or other contaminants, however. Exposure to excessive amounts of mercury through breast milk can pose a risk to a baby's developing nervous system. To limit your baby's exposure, avoid seafood that's high in mercury, including swordfish, king mackerel and tilefish. 
Chocolate contains small amounts of caffeine and larger amounts of the closely related compound, theobromine. It also contains anandamide and two related compounds that stimulate cannabinoid receptors, tryptophan, and polyphenols. All these compounds are detectable in breastmilk in small amounts. A low intake of chocolate by a nursing mother is not problematic, but extreme amounts can affect the infant.
