Foods To Avoid When Breastfeeding

There are many foods to avoid when breastfeeding. One reason is that they may not have much nutritional value compared to others. Another reason could be the risk of eating these outweigh the nutritional gain. Either way, you should do your best to keep them out of your system. Continue reading to learn more about foods that you should avoid when breastfeeding.

How Foods Effect Breast Milk

What you eat plays an important role in breastfeeding. That is because your baby is getting the nutrients it needs from the breast milk. It gets these nutrients from the foods you eat, but it can also get some harmful things as well. However, there are some foods that can actually harm your newborn so it is important to stay away from them.

Foods to Avoid:


When you are pregnant with your baby you are told to stay away from alcohol. That is because it poses a huge threat to the health of your child. Now that they are here though, you can loosen up on that rule. Having one or two drinks a week won’t cause any harm to your child. Just give the alcohol about two to three hours to pass through your system before feeding again. If you don’t wait or are having drinks too frequently your newborn is at risk of improper developments.


Fish can actually be a nutrient-rich food when it is cooked the right way. However,  a lot of fish and other seafood contains mercury. When it is in the body, mercury can pile up and rise to dangerous levels. These high levels can affect the nervous system and can cause neurological defects in your child.

Due to this pregnant and nursing mothers are advised against consuming high-mercury foods. Some examples of fish that are high in mercury are Shark, Swordfish, King Mackerel, Tuna, and Tilefish.

Cow Milk:

According to a recent study, Cow’s Milk Protein Allergy, (CMPA), affects about 2 to 6% of children. The only way they have access to this is through the mother’s diet. If your newborn develops rashes, diarrhea or is vomiting, try excluding all cow’s milk protein from your diet for at least two to four weeks. This includes foods such as:

  • Cheese: Any cheese including cottage and cheese sauces
  • Cream: Sour Cream included
  • Milk, buttermilk, powdered milk, and evaporated milk
  • Sweets such as pudding and ice cream


There are other foods that should be avoided as well. Some of these include chocolate, caffeinated drinks, fruits with a laxative effect such as cherries and prunes, and the “gassy” foods. The “gassy” foods include onion, cabbage, garlic, cauliflower, broccoli, cucumbers, and peppers. While you don’t have to completely eliminate these foods from your diet, it is important to limit these foods to a minimum.

If you are having trouble keeping dairy out of your diet you can always substitute milk with almond milk and other dairy-free foods. That way you are still getting the nutrients that you and your newborn need.
