A Complete Run-Down on Foods to Avoid during Breastfeeding

You would’ve heard a lot about the benefits of breastfeeding. But did you know there’s a breastfeeding diet that one needs to follow? Worry not, it’s not a complex diet to follow. Rather it’s all about infusing nutrient-dense food on your plate. To know more, keep on reading to find out which foods to avoid during breastfeeding and which to eat that would provide the best nutrition to you and your little one.

Do You Need to Follow a Special Breastfeeding Diet?

There is no specific menu or diet regimen that you, as a breastfeeding mom, definitely need to follow. Instead, try to eat a normal, healthy diet to help maintain your breast milk supply and support your and your baby’s nutritional needs.

Just as you should at other times in life, it’s important when you’re breastfeeding to enjoy a well-rounded diet that includes fruits, vegetables, whole grains, protein, and foods rich in calcium and minerals. To help you do this, check out ChooseMyPlate.gov, which lets you select healthy options from each of the main food groups and provides tips and a personalized food plan for breastfeeding moms.

Why Do You Need To Follow A Good Breastfeeding Diet?

Producing breast milk is a demanding task on a woman's body. It’s because your body requires 500 - 1,000 calories a day to produce milk. Out of which, half of the calories are derived from your body fat whereas the other half comes from the food that you have every day. On the other hand, there’s a need for high levels of nutrients. All of this makes it prudent for a breastfeeding mom to have a healthy balanced diet.

Foods to Eat While Breastfeeding

It’s necessary to consume a sufficient amount of certain nutrients while you’re breastfeeding since you’ll be passing on those nutrients to your little one through your breast milk. Read on to find out what the best foods for breastfeeding are.

  • Calcium-Rich Foods

One of the most important dietary minerals is calcium, which helps keep your bones healthy and strong. That's why you'll need to make sure you get your daily dose of 1,000 milligrams (1,300 for teenaged mothers). Studies show that moms lose about 3 to 5 percent of their bone mass while breastfeeding. To help offset this, make sure you load up on calcium while you’re breastfeeding.

Shoot for three servings of dairy products per day, which can include things like milk, cheese, and yoghurt. To give you an idea of serving size, eight ounces of milk is one serving.

Calcium-rich dairy alternatives include:

1. Calcium-fortified juices 2. Tofu 3. Dark leafy greens like kale, spinach, and broccoli 4. Dried beans 5. Fortified breakfast cereals

Talk to your healthcare provider if you are having trouble reaching the 1,000 milligrams per day recommendation. Your provider may recommend a calcium supplement, which should be made without crushed oyster shells, as these can contain lead.

  • Folate-Rich Foods

To support your baby’s ongoing development, aim for at least 400 micrograms of folate (folic acid) per day. Your provider may recommend taking a multivitamin or tell you to keep taking your prenatal vitamin to get enough folate.

You’ll also want to eat folate-rich foods such as spinach, citrus fruits, meat or poultry liver, and a variety of beans. You can also get folate from folate-enriched breads, cereals, and grains.

  • Foods Rich in Vitamin D

Vitamin D, along with calcium, is crucial for maintaining bone strength. Although sun exposure is one of the best ways to get vitamin D, it’s not the safest method, given the risks of skin cancer, nor is it always practical. You can obtain a good supply of vitamin D through foods such as:

1. Salmon 2. Mackerel 3. Fortified milk or orange juice 4. Yoghurt

Most experts recommend between 400 and 1,000 IU (international units) of vitamin D per day. To give you some examples of foods high in vitamin D, three ounces of cooked sockeye salmon has 477 IU, a can of tuna in water has 154 IU, and 1 cup of fortified orange juice has 137 IU.

The good news is that fish like salmon, tuna, and mackerel are also rich in omega-3 fatty acids, which help promote the growth and development of your baby’s brain and eyes.

Getting plenty of vitamin D is also important because it helps your digestive tract absorb calcium.

Your baby’s healthcare provider may recommend a vitamin D supplement for your baby. This is because babies who are exclusively breastfed are at risk of developing a condition called rickets (a softening and weakening of bones) if they don’t get enough vitamin D from breast milk alone.

  • Foods High in Protein

When you’re nursing you need six to six-and-a-half ounces of protein a day, which helps build, repair, and maintain body tissues. Aim for two or three servings of lean meat, poultry, or fish, knowing that a three-ounce serving is about the size of a deck of cards.

You can also get 1-ounce protein equivalents from 1 egg, 1 tablespoon of peanut butter, nuts (such as 12 almonds or 24 pistachios), or a quarter cup of cooked beans.

If peanut allergies run in your family, pay especially close attention to how your baby responds after you’ve consumed peanuts or peanut butter. Speak to your healthcare provider if you have any concerns.

  • Iron

Lean meats and dark, leafy green vegetables are great sources of iron; fish, iron-fortified cereals, and dark poultry meat also contain this important mineral. The body more easily absorbs iron from animal sources than from plant sources. Your healthcare provider may recommend taking iron supplements to ensure you’re getting enough in your diet while breastfeeding.

  • Water

You may notice that you are thirstier than usual while you’re lactating. It’s important to make sure you’re drinking enough water every day. A good tip is to drink a glass of water every time you breastfeed.

Foods to Avoid or Limit While Breastfeeding

After carefully watching what you were eating during your pregnancy, you might hope that after your baby’s birth you can go back to eating and drinking the way you were beforehand. However, there are still some foods and drinks to be wary of when breastfeeding.

Below are some of the foods and drinks to avoid or limit while breastfeeding.

  • Seafood That’s High in Mercury

Fish can play an important role in a healthy diet since it’s rich in protein and omega-3 fatty acids. However, some types of fish contain high levels of mercury, which can cause damage to the nervous system in babies and small children. For this reason, avoid fish such as shark, swordfish, king mackerel, and tilefish.

Instead, stick to fish such as canned light tuna (limit canned albacore tuna to no more than six ounces per week since it contains more mercury), shrimp, salmon, pollock, and catfish.

If you like locally caught fish, check local advisories about the safety of the fish. For more information on the mercury levels of the different types of fish, check out this handy guide from the FDA.

  • Alcohol and Breastfeeding

Long-term, repeated alcohol consumption can reduce your breast milk supply and may be harmful to your baby. Alcohol also changes the way your breast milk tastes, which your baby may not like. That's why it's best to avoid alcohol altogether.

If you must have an occasional alcoholic drink, have one just after you’ve nursed your baby or expressed/pumped, and wait at least a couple of hours before you breastfeed, express, or pump again. This gives your body enough time to metabolize the alcohol.

  • Caffeinated Beverages and Breastfeeding

Drinking up to three cups of caffeinated beverages while breastfeeding a day is usually OK. Any more can make your baby fussy or irritable.

Keep in mind, there’s caffeine in coffee, but there’s also caffeine in some teas, sodas, and chocolates, so factor all these into your calculations of how much caffeine you’re consuming.

  • Sugary Drinks and Breastfeeding

Try to limit or avoid sugary drinks, including soft drinks like fruit juices and iced teas. Instead, drink lots of water.

A Note On Vitamins and Supplements

Your healthcare provider may have you continue taking your prenatal vitamins or a multivitamin until you wean your baby.

Iodine is another crucial mineral while you’re breastfeeding. Your healthcare provider may recommend you take a supplement that includes the 150 micrograms needed per day.

If you adhere to a vegan or vegetarian diet, your healthcare provider may recommend a daily vitamin B-12 supplement. Vitamin B-12, which is essential for your baby’s brain development, is contained in much higher levels of animal protein than in vegetables. Your provider may also recommend an omega-3 supplement if you’re not eating fish.

Food Reactions, Intolerances, and Allergies That May Affect Your Baby

Your baby may have a reaction to your breast milk after you’ve had certain foods or drinks. For example:

  • After you eat beans, cabbage, broccoli, or cauliflower, your baby may get gassy or fussy.

  • After you’ve had spicy food, your baby may not like the taste of your breast milk because it can change the taste.

  • Your little one may be more fussy or irritable if you’ve had too much caffeine.

  • Your baby may also develop an allergic reaction after you’ve had cow’s milk, soy, wheat, corn, oats, eggs, tree nuts, peanuts, fish, or shellfish.

Signs of an allergic reaction in your baby include

  • Frequent spitting up or vomiting

  • Belly pain

  • Lots of gas

  • Pulling up the knees in pain

  • Blood or mucus in his stool

  • Hard poops

  • Skin rashes and swelling

Call your doctor immediately if your baby has trouble breathing or his face swells. Reach out to your baby's healthcare provider if you’re concerned that your baby may be unwell after feeding.

In some cases, you might consider keeping a food diary to track any possible allergies or intolerances, gassiness, fussiness, or signs of colic, and then go back to your baby’s healthcare provider with the results. The provider may suggest an elimination diet, which means eliminating certain food from your diet to see if there’s a change in your baby’s response.
