⚠️ Common Concerns

Almonds are totally safe while breastfeeding and are a wonderful snack! They're packed with calcium, vitamin E, and healthy fats — all great for nursing moms.

Artificial food dyes are a real — if underresearched — concern. Small amounts of synthetic dyes may pass into breast milk. While definitive proof is limited, many health-conscious moms prefer to minimize them.

Beans do NOT make your baby gassy through breast milk! The gas-causing sugars in beans are digested in your gut — they never reach your bloodstream or your milk.

Broccoli does NOT make your baby gassy! This is one of the most persistent breastfeeding myths. Gas-causing carbohydrates in broccoli stay in your gut — they don't travel into your milk.

Cabbage will not make your baby gassy — eat it freely! The gas-causing compounds in cabbage don't pass through breast milk. Cabbage is nutritious and worth keeping in your diet.

Moderate caffeine intake (up to 300mg/day, about 2–3 cups of coffee) is safe while breastfeeding. Only about 1% of your caffeine dose appears in breast milk, and at moderate levels, this amount is well tolerated by most babies. Newborns metabolize caffeine more slowly, so be more conservative in the first few weeks.

Cashews are safe to enjoy while breastfeeding! They're a great source of magnesium, zinc, and iron — nutrients nursing moms need plenty of.

Cauliflower won't make your baby gassy. The gas-causing carbohydrates in cruciferous vegetables stay in your gut and don't pass into breast milk — so eat up!

Chocolate is safe to enjoy in moderation while breastfeeding! It contains a small amount of caffeine and theobromine, but regular portions are completely fine for most babies.

Citrus fruits are safe while breastfeeding! The myth that they cause rashes or stomach upset in babies through breast milk isn't supported by evidence.

Coconut is safe to eat while breastfeeding. While the FDA classifies coconut as a tree nut for labeling purposes, it's botanically a fruit (drupe), and coconut allergy is quite rare. Coconut provides healthy medium-chain fatty acids (MCTs) that may actually support breast milk fat content. No need to avoid coconut unless your baby has a confirmed allergy.

Corn is generally fine while breastfeeding, but it's worth knowing that corn is a relatively common food sensitivity trigger for some infants. Most babies tolerate it well.

Cow's milk protein allergy (CMPA) is one of the most common infant food allergies, and dairy proteins can pass into breast milk. If your baby shows signs of CMPA, a dairy elimination trial may be recommended.

Dairy is safe to consume while breastfeeding for most mothers. While cow's milk protein intolerance (CMPI) does affect about 2–3% of breastfed infants, the vast majority of babies tolerate maternal dairy consumption perfectly well. Don't eliminate dairy preventively — only if your baby shows specific symptoms (blood in stool, persistent eczema, significant GI distress) confirmed by your pediatrician.

Deli meat is safe while breastfeeding! The pregnancy restriction was about listeria risk to the fetus — that concern doesn't apply once your baby is born and you're nursing.

Eggs are safe to eat while breastfeeding for most moms. Egg allergy in infants through breast milk is uncommon, and there's no reason to avoid them unless your baby has a confirmed egg allergy.

Exercise does not make your breast milk 'sour' or harmful to your baby — this is a persistent myth. While intense exercise does temporarily increase lactic acid in breast milk, studies show babies accept the milk just fine. Moderate exercise has no effect on milk volume, composition, or your baby's growth. Stay active — it's great for your physical and mental health postpartum.

An occasional fast food meal is totally fine while breastfeeding — no guilt needed! Just know that a steady diet of fast food isn't ideal since it tends to be high in sodium and low in the nutrients you need.

Fish is safe — and actually encouraged — while breastfeeding! The FDA recommends 2-3 servings of low-mercury fish per week. Fish allergy concerns shouldn't keep most nursing moms from eating fish.

Garlic is safe and won't make your baby gassy! Some studies have found that garlic flavor in breast milk can actually make babies nurse longer — they seem to like the taste.

Honey is completely safe for breastfeeding moms to eat! The no-honey rule is for babies under 12 months eating honey directly — it does NOT apply to what you eat.

Lupin (lupini beans and lupin flour) is safe to eat while breastfeeding. Lupin is recognized as a major allergen in the EU but is less commonly known in the US. It's increasingly found in gluten-free products as lupin flour. If your baby has a peanut allergy, be aware of potential cross-reactivity — lupin is in the same legume family.

Mustard is safe to consume while breastfeeding. While mustard is recognized as a major allergen in Europe and Canada, there's no reason to avoid it unless your baby has a confirmed mustard allergy. Mustard proteins can pass into breast milk in trace amounts, which — like other food proteins — is generally thought to promote tolerance rather than sensitization.

Nightshade vegetables — tomatoes, peppers, eggplant, and potatoes — are safe to eat while breastfeeding. The claim that nightshades cause inflammation or fussiness in breastfed babies is not supported by evidence. These vegetables are nutritious and there's no reason to avoid them unless your baby has a specific, confirmed sensitivity.

Onions won't give your baby gas through your milk. This is a myth! The gas-producing compounds in onions stay in your digestive tract and don't transfer to breast milk.

Peanut butter is safe and nutritious while breastfeeding! Current research actually suggests that eating peanuts while nursing may help reduce your baby's risk of developing a peanut allergy.

Peanuts are safe to eat while breastfeeding! Current research actually suggests that eating peanuts during nursing may help protect your baby from developing a peanut allergy later.

Pineapple is totally safe while breastfeeding! It's nutritious and won't cause any problems for your baby through breast milk.

Occasional processed food is fine, but a steady diet of ultra-processed foods isn't ideal while breastfeeding. Your nutrition directly affects the nutritional quality of your milk — and your own energy levels.

Sesame is safe while breastfeeding. It's now recognized as a major allergen in the US, but that doesn't mean nursing moms need to avoid it — only babies with a diagnosed allergy require dietary changes.

Shellfish is safe to eat while breastfeeding! It's a top allergen, but nursing moms don't need to avoid it unless their baby has a confirmed shellfish allergy.

Soy is safe for most breastfeeding moms. It's a top-8 allergen, but the vast majority of babies tolerate it just fine through breast milk.

Spicy food does NOT make your breast milk spicy or cause your baby discomfort! This is one of the most common breastfeeding myths out there.

Strawberries are perfectly safe while breastfeeding. The old worry that they cause rashes in babies through breast milk has no scientific backing.

Eating sugar does not 'put sugar in your breast milk' in the way many people fear. Breast milk always contains lactose (milk sugar) at a consistent level of about 7% regardless of your diet. Your dietary sugar intake doesn't meaningfully change breast milk sugar content. That said, a balanced diet is still best for your overall health and energy levels during the demanding postpartum period.

Tomatoes are perfectly safe to eat while breastfeeding. The common belief that acidic foods like tomatoes cause fussiness or diaper rash in breastfed babies is a myth — the acidity of foods you eat does not change the pH of your breast milk. Your body tightly regulates breast milk pH regardless of your diet.

Tree nuts are safe and nutritious to eat while breastfeeding. Current evidence does not support restricting maternal nut consumption to prevent allergies in breastfed babies — in fact, early exposure through breast milk may help reduce allergy risk. If your baby shows signs of a reaction (eczema, hives, blood in stool), consult your pediatrician about an elimination trial.

Walnuts are safe and actually a fantastic choice while breastfeeding. They're one of the best plant-based sources of omega-3 fatty acids, which support your baby's brain development through your milk.

Wheat and gluten are safe while breastfeeding for most moms. Unless your baby has been diagnosed with celiac disease or a wheat allergy, there's no need to go gluten-free.
