Are Mushrooms Good for Pregnancy and Breastfeeding?
The Truth About Toxins, Superfoods, and Safety
Congratulations on your journey!
Whether you are glowing with a baby bump or navigating the sleepless nights of nursing, as a former WIC dietitian and NICU/pediatric nurse/lactation consultant, I know exactly how overwhelming the "do not eat" list can seem.
It seems like every time you turn around, another favorite food gets slapped with a warning label, doesn't it?
So...are mushrooms good for pregnancy and breastfeeding?
You want to nourish your body and your baby with the best earth-grown foods, but the fear of making a mistake is real.
When it comes to fungi, the confusion is even thicker than a forest fog.
You might be asking, "Can I eat mushrooms at all right now?"
The short, reassuring answer is a resounding yes—but with a few very specific rules of engagement.
Let’s take a deep breath, push aside the anxiety, and look at exactly how to enjoy these earthy delights safely.
Let’s start with the easy stuff: the grocery store classics
If you are wondering, "Are mushrooms good for pregnancy?" when looking at the produce aisle, the answer is yes!
Common culinary mushrooms like:
- White Button
- Cremini (Baby Bella)
- Portobello
- Shiitake
- Oyster, and
- Enoki
...are generally safe to eat.
These varieties are grown in controlled environments, which drastically reduces the risk of contamination compared to their wild cousins.
They are fantastic for you because they are packed with B vitamins and essential minerals.
Think of these store-bought varieties as your reliable friends; they are predictable, safe, and delicious when treated right.
You can confidently toss these into your cart without losing sleep.
Now, we have to talk about the "danger zone."
In addressing the question, "Are mushrooms good for pregnancy?"...
I know many of us love the idea of foraging and connecting with nature, but pregnancy is not the time to experiment with wild mushrooms.
Even seasoned experts can make mistakes with identification, and the consequences of eating a toxic wild mushroom can be severe for both you and your little one.
Studies indicate that boiling or frying mushrooms can reduce agaritine content by up to 90%, whereas simple washing only removes a negligible amount.
Furthermore, you absolutely must avoid raw mushrooms.
This is for everyone...not just pregnant and breastfeeding women.
Raw fungi contain small amounts of naturally occurring toxins (like agaritine) and have tough cell walls made of chitin that are hard on your digestion.
Plus, raw produce carries a higher risk of harmful bacteria like listeria or salmonella.
I know you see and find raw mushrooms everywhere, but we as humans do not possess the adequate digestive enzymes to break down raw mushrooms.
So, skip the raw mushroom salad at the bistro and steer clear of anything you picked from the backyard yourself!
However, once cooked, that same chitin acts as a prebiotic fiber. It feeds the beneficial bacteria in the gut, which can be helpful since digestion often slows down during pregnancy due to hormonal changes.
Since we ruled out raw, let's talk about the magic of heat.
Cooking is your best defense and your culinary best friend right now.
Thoroughly cooking your mushrooms breaks down those tough cell walls, making the nutrients bioavailable so your body can actually absorb them.
More importantly, heat kills off nasty bacteria that could make you sick.
Functional mushrooms
Are mushrooms good for pregnancy in the concentrated form?
Here is where things get a little murky for the natural-health crowd: medicinal mushrooms and supplements.
You might be seeing ads for:
- Reishi
- Chaga
- Lion’s Mane, or
- Turkey Tail powders and supplements everywhere.
While these are powerful tools in a holistic lifestyle, we simply don't have enough research to confirm they are safe for a developing fetus.
Western medicine is slow to study these ancient remedies, and because supplements aren't strictly regulated, you can't always be sure of the purity or dosage.
It is frustrating, I know!
But until we have more concrete data, it is usually wiser to press pause on the concentrated adaptogen powders and stick to eating whole, culinary mushrooms instead.
Is microdosing psilocybin safe for pregnancy and breastfeeding?
I know there is a massive resurgence of interest in plant medicine for mental health, and you might be open-minded about these things.
However, during pregnancy and breastfeeding, this is a hard "no."
Psilocybin is a powerful compound that crosses the placental and blood-brain barrier and enters breastmilk.
We have zero safety data on how this affects a baby's developing brain, and the legal and health risks are just too high.
I have had several women tell me how microdosing mushrooms helped them tremendously in navigating the muddy waters of postpartum depression....
I WILL NEVER advise pregnant and breastfeeding women to microdose mushrooms.
If you choose this route, however, treat it like drinking alcohol and always pump-and-dump if you have microdosed while breastfeeding.
Mushrooms are the richest plant source of selenium. Just one cup of cooked shiitake mushrooms provides nearly 65% of the Daily Value. Selenium is linked to reduced risks of preeclampsia and is essential for thyroid function.
The nutrition of it all
Let’s circle back to nutrition because you are building a human being and need high-quality fuel!
Are mushrooms good for pregnancy in terms of vitamins and minerals?
Absolutely!
As a dietitian I have yet to meet a nutritional profile more impressive than the mighty mushroom.
They are one of the few non-animal sources of Vitamin D (especially if they were exposed to sunlight), which is crucial for building your baby's bones.
They are also rich in selenium, an antioxidant that helps support your immune system, and they provide a nice hit of protein and fiber.
While many people focus on folate (Vitamin B9) for pregnancy, mushrooms are incredibly high in Riboflavin (B2) and Niacin (B3). These are essential for converting food into fuel, helping combat the "pregnancy fatigue" mentioned in the introduction.
If you are dealing with food aversions to meat, the meaty texture of cooked gourmet mushrooms can be a lifesaver.
You are getting nutrient density without the heaviness, helping you feel energized rather than sluggish.
The savory flavor is caused by glutamate, an amino acid found naturally in mushrooms. This triggers the "fifth taste" (umami). For pregnant women trying to lower their salt intake to manage blood pressure, using mushrooms adds savory depth without the need for excessive sodium.
Once the baby arrives, you might wonder if the rules change.
Navigating mushrooms while breastfeeding is very similar to pregnancy.
You can continue to enjoy all those cooked, culinary mushrooms we talked about.
They are great for replenishing the nutrients your body uses to make milk.
The only thing to watch for is your baby’s reaction.
Occasionally, some foods in a mother's diet can cause gas or fussiness in a sensitive newborn.
If you eat a big bowl of mushroom risotto and notice your little one is extra gassy the next day, you might want to make note of that and make some changes.
But generally, if it was safe while you were pregnant, it is safe while you are nursing.
A single portobello mushroom contains more potassium than a medium-sized banana. Potassium is vital during pregnancy as it helps maintain fluid and electrolyte balance, reducing leg cramps and swelling (edema).
Let's get practical about handling and storage.
When you bring your mushrooms home, store them in a paper bag in the fridge; plastic tends to make them slimy, and slime is a sign of spoilage you want to avoid.
Before you cook them, give them a good wash.
I usually ride with the old-school chefs that say "never wash mushrooms," but when you are pregnant, hygiene trumps culinary tradition!
Rinse the dirt off thoroughly under running water and pat them dry with a paper towel immediately.
If a mushroom looks bruised, slimy, or smells fishy, trust your instincts and toss it in the compost.
It is better to waste a few dollars than to risk a stomach bug.
Finally...
I know you might be skeptical of doctors who only push pills, but your healthcare provider is still a vital partner.
If you are taking a specific mushroom supplement for a health condition, bring the bottle to your next appointment.
Ask them specifically, "Are mushrooms safe for pregnancy in this concentrated form?"
Sometimes, they might give you the green light if the benefit outweighs the risk, or they might suggest a safer alternative.
Don't be afraid to ask questions or advocate for your natural lifestyle preferences.
It is your body and your baby, and you deserve to have all the information to make the right call.
So...are mushrooms good for pregnancy and breastfeeding?
Ultimately, you can breathe a sigh of relief.
You don't have to banish fungi from your kitchen!
By:
- sticking to store-bought varieties,
- cooking them thoroughly, and
- pausing the heavy-duty supplements,
...you can safely enjoy the earthy goodness of mushrooms.
Listen to your body—if the smell of them cooking makes you nauseous today, skip it.
If you are craving a savory stir-fry, go for it!
You are doing an amazing job navigating this complex, beautiful season of life.
Trust your intuition, keep things cooked and clean, and enjoy a delicious, healthy meal knowing you are taking great care of yourself and your little one.
