What to Eat (and What to Avoid) While Breastfeeding—Without Diets, Guilt, or Restriction

As a new parent, you're likely hearing a lot of advice: some helpful, some overwhelming, and some downright confusing. Advice about what you should or shouldn’t eat while breastfeeding. As both a lactation consultant and mental health nurse, I want to offer you reassurance, clarity, and above all, a permission slip to nourish yourself without guilt or pressure.

Let’s get one thing straight from the start:


Breastfeeding is not a time for dieting or restriction.

Your body is doing something powerful—producing milk, healing, adapting to a new rhythm—and it deserves support, not scrutiny.

So, What Should You Eat?

The simple answer? Enough.

Your body needs energy to recover from birth, fuel milk production, and support your own physical and emotional well-being. That means regular, satisfying meals and snacks that you enjoy and that make you feel good.

Here are some gentle, no-pressure guidelines:

  • Eat a variety of foods if you can—whole grains, protein, fruits, veggies, and fats. No need to be perfect or “clean”—this isn’t about rules, it’s about balance.
  • Listen to your hunger cues. Breastfeeding can increase your appetite—and that’s normal and healthy.
  • Stay hydrated. Drink to thirst. Water, milk, juice, tea—whatever helps you feel refreshed.
  • Keep snacks accessible. A granola bar, a handful of nuts, a sandwich, or a banana near your nursing spot can go a long way.

Foods to Avoid? Not Many.

There are very few foods that breastfeeding people need to avoid entirely. Most of what you’ll hear about “problem foods” is either outdated or unnecessarily fear-based.

Here’s what we actually know:

  • Caffeine: Totally fine in moderate amounts. Up to 1-2 cups of coffee a day is generally considered safe.
  • Alcohol: Occasional, moderate alcohol (like a glass of wine) is okay. Wait 2–3 hours after drinking before breastfeeding—or pump ahead if that feels easier.
  • Spicy or “gassy” foods: Unless your baby shows a clear reaction, there's no reason to avoid foods like garlic, beans, kimchi, hot sauce or broccoli. In fact, flavors from your diet may help broaden your baby’s palate over time.
  • Fish with high mercury: Avoid excessive amounts of high-mercury fish (like swordfish), but low-mercury options like salmon and sardines are safe and healthy.

If your baby seems fussy, gassy, or has digestive issues, talk to a pediatrician or IBCLC before cutting foods. Don’t self-diagnose or restrict unnecessarily—it can cause more stress than benefit.

💬 Let’s Talk About Food Guilt

You don’t have to “eat clean.” You don’t have to lose the baby weight. You don’t have to earn your meals with movement or limit carbs or sugar to be a “healthy” breastfeeding parent.

Your body is wise. It knows how to feed your baby. It just needs you to feed yourself.

Food is fuel, yes—but it’s also connection, comfort, and culture. There is space for cookies and kale, takeout and toast, smoothies and sandwiches. There is space for rest, softness, and kindness toward yourself.

🌿 Nourishment Supports Mental Health, Too

In the haze of newborn days, it’s easy to forget to eat or to put your own needs last. But your mental health matters—and eating regularly and adequately is foundational to mood stability, energy, and emotional resilience.

If you’re finding it hard to eat due to stress, depression, anxiety, or appetite loss, know that you’re not alone. Please reach out to a trusted health care provider, therapist, or support group. Nourishing your mind is just as important as nourishing your body.

👩‍⚕️ Final Thoughts: Trust Your Body, Trust Yourself

You don’t need to follow a perfect plan to breastfeed successfully. There’s no magical diet that guarantees the “best” milk. The best thing you can do is feed yourself with care, compassion, and consistency.

And if you're ever unsure—whether about your baby’s feeding, your milk supply, or your own wellness—reach out to a lactation consultant or mental health professional. That’s what we’re here for.

Gentle Reminder:
You’re already doing a great job. Eating to feel strong, cared for, and human isn’t selfish—it’s smart. Your baby needs you, not perfection.
