Title: “Breastfeeding and Diet: When you breastfeed what not to eat”

Congratulations, new mom! You’ve embarked on one of the most incredible journeys of your life – breastfeeding your baby. Breastfeeding offers numerous benefits for both you and your little one, but it also comes with some dietary considerations. What you eat can have a direct impact on your baby’s well-being, and it’s crucial to make informed choices. In this blog post, we’ll explore what not to eat while breastfeeding, providing you with valuable insights to ensure a happy and healthy breastfeeding journey for both you and your baby.

The Connection between Diet and Breastfeeding

Before we delve into what not to eat, it’s essential to understand the connection between your diet and breastfeeding. Your breast milk is your baby’s primary source of nutrition, so what you consume directly affects the quality and composition of your milk. Here’s why your diet matters:

  1. Nutrient Transfer: Nutrients from your bloodstream are passed on to your breast milk, providing your baby with essential vitamins, minerals, and macronutrients.
  2. Flavor Development: The flavors of the foods you eat can influence your baby’s taste preferences and introduce them to a variety of tastes early on.
  3. Allergenic Potential: Certain foods can trigger allergies or sensitivities in your baby through breast milk.
  4. Digestive Impact: Some foods can make your baby gassy, fussy, or experience colic-like symptoms.

Foods to Avoid While Breastfeeding

Now that you understand the importance of your diet, let’s dive into the foods you should avoid or consume in moderation while breastfeeding:

  1. Caffeine: While a morning coffee might be your lifeline, excessive caffeine can lead to a fussy and irritable baby. Limit your caffeine intake to 2-3 cups of coffee per day.
  2. Alcohol: Avoid alcohol altogether, or consume it sparingly and in moderation. Alcohol can pass into breast milk and affect your baby’s development.
  3. Spicy Foods: Spicy foods can upset your baby’s sensitive stomach. If you crave spice, consume it in moderation and observe your baby’s reactions.
  4. High Mercury Fish: Fish like shark, swordfish, king mackerel, and tilefish contain high levels of mercury, which can harm your baby’s developing nervous system. Opt for low-mercury fish like salmon, trout, and sardines instead.
  5. Dairy Products: Some babies are sensitive to dairy, and consuming dairy can lead to colic or upset stomach. If you suspect this, try cutting dairy from your diet and see if it makes a difference.
  6. Nuts: While most nuts are safe, if you have a family history of nut allergies, consult your doctor before consuming them. Nut proteins can pass through breast milk and trigger allergic reactions.

Managing Allergies and Sensitivities

If your baby shows signs of allergies or sensitivities, it’s essential to identify the culprit and make necessary adjustments to your diet. Common allergens include:

  1. Cow’s Milk: If you suspect a cow’s milk allergy, try eliminating dairy products from your diet and look for dairy alternatives like almond or soy milk.
  2. Gluten: Some babies may be sensitive to gluten. Consider going gluten-free for a while and see if it makes a difference.
  3. Eggs: Eggs are another common allergen. Remove them from your diet temporarily and monitor your baby’s reaction.
  4. Soy: In rare cases, babies can be sensitive to soy. Avoid soy-based products and consult your doctor for guidance.

Keeping a Food Diary

One effective way to pinpoint any foods causing issues for your baby is to keep a food diary. Track everything you eat and note any changes in your baby’s behavior or health. This can help you identify patterns and potential triggers more easily.

Hydration and Breastfeeding

Staying hydrated is crucial for maintaining a healthy milk supply. Aim to drink plenty of water throughout the day. You can also include hydrating foods like watermelon, cucumber, and soups in your diet.

A Balanced Diet for Breastfeeding Moms

While it’s essential to avoid certain foods, it’s equally important to maintain a balanced diet that supports your health and milk production. Focus on:

  1. Lean Proteins: Incorporate lean meats, poultry, fish, and plant-based proteins like beans and tofu.
  2. Fruits and Vegetables: Load up on a variety of colorful fruits and vegetables to get essential vitamins and antioxidants.
  3. Whole Grains: Opt for whole grains like brown rice, quinoa, and whole wheat bread to provide sustained energy.
  4. Healthy Fats: Include sources of healthy fats like avocados, nuts, and olive oil in your diet.
  5. Iron-Rich Foods: Iron is essential for both you and your baby. Incorporate iron-rich foods like spinach, lean red meat, and fortified cereals.

Common Myths about Breastfeeding and Diet

Let’s debunk some common myths about breastfeeding and diet:

  • Myth 1: You need to eat for two. While you do need additional calories while breastfeeding, it’s not double your pre-pregnancy intake. Quality matters more than quantity.
  • Myth 2: Spicy foods will make your baby gassy. While some babies are sensitive to spice, not all will be affected. It’s about finding a balance that works for you and your baby.
  • Myth 3: You must drink milk to produce milk. Milk production is not solely dependent on dairy consumption. Focus on a well-rounded diet and staying hydrated.
  • Myth 4: You can’t lose weight while breastfeeding. While breastfeeding can help burn extra calories, it’s essential to approach weight loss carefully to ensure you and your baby’s well-being.


Breastfeeding is a unique and beautiful journey that comes with its dietary considerations. By understanding what not to eat, managing allergies and sensitivities, and maintaining a balanced diet, you can provide your baby with the best start in life while keeping yourself healthy and happy.
