Foods to avoid when breastfeeding?

HotbotBy HotBotUpdated: July 10, 2024


Breastfeeding is a crucial period that requires careful consideration of dietary choices for the health and well-being of both the mother and the baby. While breastfeeding, the nutrients and substances a mother consumes can directly affect her milk and, consequently, her infant. Understanding which foods to avoid can help ensure the baby's optimal development and mitigate any potential adverse reactions.


Caffeine is commonly found in coffee, tea, chocolate, and some soft drinks. While moderate consumption is generally considered safe, excessive intake can lead to irritability, sleep disturbances, and jitteriness in infants. Caffeine can accumulate in a baby's system because they metabolize it much slower than adults. Limiting caffeine intake to about 300 milligrams per day, equivalent to about two to three cups of coffee, is generally recommended.


Alcohol can easily pass into breast milk and affect the baby's development. Consuming alcohol while breastfeeding can impair the baby's motor development, alter sleep patterns, and reduce milk intake. If a mother chooses to consume alcohol, it is advisable to do so in moderation and to wait at least 2-3 hours per drink before breastfeeding to minimize the alcohol content in the milk.

Spicy Foods

Spicy foods can cause discomfort in some babies, leading to fussiness and digestive issues such as gas and diarrhea. While not all infants react to spicy foods, it is essential to observe any changes in the baby's behavior or digestion after the mother consumes such foods. If adverse reactions are noted, reducing the intake of spicy foods may be beneficial.

High-Mercury Fish

Certain types of fish like shark, swordfish, king mackerel, and tilefish contain high levels of mercury, which can negatively impact a baby's developing nervous system. It is advisable to opt for low-mercury fish options such as salmon, sardines, and trout, which are also rich in beneficial omega-3 fatty acids.


Common allergens like peanuts, tree nuts, eggs, dairy, soy, and shellfish can sometimes pass into breast milk and cause allergic reactions in sensitive infants. Symptoms may include rash, hives, wheezing, or gastrointestinal issues. If there is a family history of allergies, it is essential to monitor the baby for any signs of allergic reactions and consult with a healthcare provider for guidance.

Cruciferous Vegetables

Vegetables such as broccoli, cauliflower, cabbage, and Brussels sprouts are known for causing gas and bloating. While these vegetables are nutritious, they can lead to discomfort and gassiness in some breastfeeding infants. If the baby shows signs of discomfort, it might be worth moderating the intake of these vegetables.


Chocolate contains both caffeine and a compound called theobromine, which can cause irritability and sleep issues in infants. While occasional consumption is unlikely to cause problems, large amounts of chocolate should be avoided to prevent potential adverse effects on the baby.


Garlic has a strong flavor that can alter the taste of breast milk. Some babies may dislike this change, leading to fussiness and feeding difficulties. While garlic has numerous health benefits, mothers should observe their baby's reaction and adjust their intake accordingly.

Citrus Fruits

Citrus fruits and juices such as oranges, lemons, limes, and grapefruits are acidic and can sometimes cause diaper rash, fussiness, and spit-up in some infants. If the baby shows sensitivity to these fruits, it may be helpful to limit their consumption and opt for non-citrus fruits rich in vitamin C, like strawberries and melons.

Processed Foods

Processed foods often contain artificial additives, preservatives, and high levels of sugar and salt. These ingredients can affect the quality of breast milk and may lead to health issues such as obesity and hyperactivity in the long run. Opting for whole, unprocessed foods ensures better nutrition for both mother and baby.

Carbonated Beverages

Carbonated beverages can cause digestive discomfort and gas in both the mother and baby. The carbonation can lead to bloating and gassiness. Reducing the intake of fizzy drinks can help alleviate these symptoms and promote better digestion.

Mint and Parsley

Mint and parsley are herbs that, when consumed in large quantities, can reduce milk supply. While they are generally safe in moderate amounts, mothers experiencing issues with milk production may want to limit their intake of these herbs.

Navigating dietary choices during breastfeeding can be complex, as each baby responds differently to various foods. By being mindful of potential irritants and allergens, mothers can create a more comfortable and nourishing environment for their infants. As always, consulting with healthcare providers for personalized advice can provide additional guidance tailored to individual needs and circumstances.
