Can You Eat Mushrooms During Pregnancy?

Nutritional profile and health benefits of mushrooms

While mushrooms are low in dietary fats and calories, they’re rich in B vitamins and minerals and boast both antioxidant and anti-inflammatory properties (1Trusted Source, 2Trusted Source).

What’s more, they act as prebiotics to support good gut health (3Trusted Source).

On average, one-half cup (84 grams) of culinary mushrooms provides (1Trusted Source, 5Trusted Source, 6Trusted Source, 7Trusted Source):

• Carbs: 19 grams
• Protein: 2.9 grams
• Fats: 0.4 grams
• Niacin: 21% of recommended daily value (DV)
• Riboflavin: 22% DV
• Selenium: 27% DV

Oyster mushrooms are slightly higher in calories, protein, and dietary fiber than other types, but they’re a poor source of selenium (1Trusted Source, 8Trusted Source).

Mushrooms exposed to ultraviolet (UV) radiation, such as that from sunlight or a UV lamp, are an abundant and important vegetarian source of vitamin D (1Trusted Source, 9Trusted Source).

Vitamin D is essential for fertility and pregnancy, during which it supports bone health. This vitamin is associated with a reduced risk of adverse health outcomes during pregnancy (10Trusted Source).

Summary

Culinary mushrooms are an excellent source of B vitamins, selenium, and potentially vitamin D (if you purchase mushrooms that were exposed to UV light). These fungi also have antioxidant and anti-inflammatory properties.

Types of mushrooms to eat while pregnant

In short, mushrooms offer many nutritional benefits and can be safely consumed during pregnancy.

Although mushrooms are generally considered safe to eat when you’re pregnant, it’s important to choose the safest types.

Culinary mushrooms

Culinary mushrooms, such as shiitake, portobello, oyster, maitake, chestnut, crimini, and white button mushrooms, are generally safe to consume (1Trusted Source, 11Trusted Source, 12Trusted Source).

A study in pregnant rats showed that shiitake consumption lowered triglyceride levels in the mother, without causing any developmental changes in the fetus (11Trusted Source).

Another study among 1,162 pregnant women found that consuming 100 grams of white button mushrooms daily from pre-pregnancy up to 20 weeks of pregnancy reduced high blood pressure and the risks of developing gestational diabetes and preeclampsia (12Trusted Source).

Medicinal mushrooms

The medicinal mushrooms chaga, turkey tail, lion’s mane, reishi, and Cordyceps are generally safe for consumption, too. They may reduce blood cholesterol, have anti-ulcer properties, and improve immunity in the general population (13Trusted Source, 14Trusted Source, 15Trusted Source).

However, studies among pregnant people are lacking. More research is needed on their safety during pregnancy.

Summary

Both culinary and medicinal mushrooms are generally safe to consume, although culinary mushrooms have been studied more extensively. Culinary mushrooms may offer some benefits and do not appear to cause developmental harm to fetuses.

Types of mushrooms to avoid while pregnant

Magic (psychedelic) mushrooms

Magic mushrooms, which contain the active psychoactive compound psilocybin, are used for their hallucinogenic and mind-altering effects (16Trusted Source, 17Trusted Source, 18Trusted Source).

They’ve been reported to cause panic attacks in some people, as well as hallucinations — seeing, feeling, or hearing something that’s not there. It’s important to note that magic mushroom use has only been fatal when combined with other drugs (16Trusted Source, 19Trusted Source).

In the past two decades, psilocybin mushrooms have become an interest of clinical studies and psychiatric medicine for their potential therapeutic effects. They may help treat anxiety, depression, and substance use disorders when used in clinical settings (16Trusted Source, 17Trusted Source, 18Trusted Source).

Magic mushrooms have not been studied during pregnancy, so more research is needed. However, given their ability to induce hallucinations and panic attacks, pregnant women are advised to avoid magic mushrooms (18Trusted Source, 19Trusted Source).

Wild (foraged) mushrooms

Wild or foraged mushrooms should likewise generally be avoided during pregnancy.

Mushroom poisoning is most often associated with foraging. Foragers, especially inexperienced foragers, may misidentify certain mushrooms and accidentally consume poisonous or psychoactive species (20Trusted Source, 21Trusted Source).

Most cases of toxicity result in gastrointestinal symptoms that often resolve in 24 hours, but in some cases, consuming toxic mushrooms requires hospitalization. Doing so can even lead to death due to the amatoxin content of poisonous mushrooms (Trusted Source20Trusted Source, 21Trusted Source).

Therefore, it’s best to only eat labeled culinary mushrooms that you obtain from reliable sources.

Summary

Magic mushrooms and foraged mushrooms should be avoided during pregnancy due to their hallucinogenic and toxic properties. You should stick to labeled culinary mushrooms obtained from reliable sources.

Tips for cooking edible mushrooms

Pregnant people can safely enjoy culinary mushrooms in a variety of ways, with a few caveats.

• Wash to remove dirt. If you’re preparing mushrooms at home, place them in a bowl of water and wash them to remove dirt, as microbes within the dirt may cause foodborne illnesses if you eat them. Then, pat them dry.
• Cook thoroughly. Undercooked mushrooms may cause dermatitis or other infections. Follow food safety guidelines, and cook and maintain hot mushroom dishes at a minimum temperature of 140^°F (60°C). Store them appropriately to reduce bacterial growth and the risk of foodborne illnesses (22Trusted Source, 23).

Summary

Culinary mushrooms should be washed and cooked thoroughly for safe consumption during pregnancy. Avoid consuming undercooked or unwashed mushrooms, as they’re more likely to cause foodborne illnesses.

The bottom line

Culinary mushrooms are safe for consumption during pregnancy once they’re washed and cooked thoroughly.

These mushrooms offer many nutritional benefits and are a rich source of B vitamins, minerals, and potentially vitamin D.

You should avoid magic mushrooms and foraged mushrooms if you’re pregnant due to their hallucinogenic and toxic properties. As a precaution, only purchase labeled culinary mushrooms from reliable food sources.
