When it comes to breastfeeding, nutrition plays a crucial role in keeping both mom and baby healthy. As a new mom, it's important to be mindful of what you eat, as certain foods can have a negative impact on your baby's health. In this blog post, we will discuss the foods that moms should avoid while breastfeeding and provide you with some helpful tips to ensure a healthy breastfeeding journey.

Foods to Avoid While Breastfeeding

While breastfeeding, there are certain foods that you should limit or avoid altogether. These foods can either affect your milk supply, cause discomfort to your baby, or pose a risk of allergenic reactions. Let's take a closer look at some of these foods:

Fish high in mercury

One food that tops the list of foods to avoid while breastfeeding is fish high in mercury. Mercury is a toxic substance that can accumulate in your body over time. When you breastfeed, the mercury can be passed on to your baby through your breast milk, which can have detrimental effects on their developing nervous system. Therefore, it's best to avoid fish such as shark, swordfish, and marlin.

Herbal supplements

While herbal supplements may seem like a natural alternative, some can have adverse effects on your baby. It's important to consult with your healthcare provider before taking any herbal supplements while breastfeeding, as they may interfere with your milk supply or cause discomfort to your baby.


Alcohol is another substance that should be avoided while breastfeeding. When you consume alcohol, it enters your bloodstream and can be transferred to your breast milk. Your baby's liver is not yet fully developed to process alcohol, so it's best to abstain from drinking alcohol during this time.


Caffeine is a stimulant that can affect both you and your baby. While it's safe to consume moderate amounts of caffeine while breastfeeding, excessive intake can lead to irritability and sleep disturbances in your baby. It's best to limit your caffeine intake and monitor your baby's reaction.

Highly processed foods

Highly processed foods are often high in added sugars, unhealthy fats, and artificial additives. These foods offer little nutritional value and can negatively impact your overall health. It's best to opt for whole, unprocessed foods to ensure you and your baby receive the necessary nutrients.

Additional Considerations

While the foods mentioned above should be avoided or limited, it's important to remember that every mom and baby is unique. Some babies may be more sensitive to certain foods than others. It's essential to listen to your body and observe your baby's reactions to different foods.

How to Tell if Your Diet is Affecting Your Baby

To identify the potential triggers, keeping a food diary can be incredibly helpful. This involves noting down everything you eat and any changes you observe in your baby's behavior. By doing so, you can start to identify patterns and determine which foods might be causing the discomfort. The first step is to make sure you are accurately recording your meals and snacks. Include details such as the type of food, portion size, and any ingredients or spices used. It's also important to note the time of day you consumed each item. 

Next, pay close attention to your baby's behavior after breastfeeding. Look for signs of fussiness, excessive gas, or colic-like symptoms. These may include crying, pulling their legs towards their tummy, arching their back, or having difficulty sleeping. Compare your food diary with your baby's behavior to identify any correlations. For example, if you notice that your baby becomes particularly fussy after you consume dairy products, it could be an indication that they are sensitive to lactose or cow's milk protein. Similarly, if you observe a pattern of gassiness after consuming certain vegetables like broccoli or beans, it may suggest that these foods are causing discomfort. 

Remember that it may take some time and experimentation to pinpoint the exact triggers. It's also important to consult with your healthcare provider or a lactation consultant for guidance and support. They can provide valuable insights and help you navigate any dietary changes that may be necessary. Once you have identified potential trigger foods, you can try eliminating them from your diet for a period of time to see if your baby's symptoms improve. It's important to note that every baby is different, and what may cause discomfort for one may not affect another. Therefore, it's crucial to listen to your baby's cues and work closely with your healthcare provider to find the best solution for both of you.

While breastfeeding, it's important to be mindful of your diet and make choices that promote the health and well-being of both you and your baby. Avoiding or limiting certain foods can help prevent discomfort and ensure a smooth breastfeeding journey. Remember to consult with your healthcare provider if you have any concerns or questions about your diet while breastfeeding.
