Pregnant women may often ask this question to their healthcare providers, “Can I eat mushrooms while pregnant?” Mushrooms can be made into delicious and nutritious dishes and added to several preparations such as soups, salads, and pizzas. However, you may be doubtful about the safety of eating mushrooms during pregnancy. Freshly picked mushrooms are protein-rich and low in calories. But you should identify the right ones to avoid the risk of toxicity. This post tells you about the health benefits of eating mushrooms when pregnant, possible risks, the types safe for consumption, and the ones you should avoid.

Can Pregnant Women Eat Mushrooms?

Yes, it is safe to consume mushrooms during pregnancy, but avoid raw mushrooms as they are carcinogenic. Also, not all mushrooms are edible, and it is important to know the difference. Cooked or dried mushrooms are good as they are highly nutritious and are rich in vitamins, minerals and trace elements (1).

What Are The Benefits Of Eating Mushrooms During Pregnancy?

Mushrooms offer excellent nutrition for your growing baby. Including them in your regular diet helps you share the benefits with the baby in the womb.

1. Abundant vitamin B

Mushrooms are natural sources of B complex vitamins including thiamine (B1), riboflavin (B2), Niacin (B3) and pantothenic acid (B5) (2), which are beneficial for the mom-to-be and the baby.

Thiamine and niacin aid in brain development of the baby, relieve fatigue and boost energy.

Riboflavin aids in keeping the skin healthy, improving eyesight and developing strong bones, muscles, and nerves.

Pantothenic acid prevents digestion issues (3).

2. Vitamin D promotes healthy bones

Vitamin D deficiency in pregnancy can cause tiredness, back pain, bone weakness, and depression. Adding mushrooms to your diet can give you abundant vitamin D (4). It helps absorb calcium in the body, to form strong bones and teeth in the baby (5). According to Tara Bassi, a licensed nutritionist, clinical herbalist, educator, and researcher from the Greater Tampa Bay Area, “Most grocery store mushrooms are grown in dark environments with no exposure to natural sunlight or ultraviolet (UV) light. If you choose to eat wild mushrooms or know where they are grown, they are more likely to be exposed to natural sunlight or UV light which will increase their vitamin D content.”

3. Protein and fiber

Protein and fiber are present abundantly in mushrooms.

Protein is necessary for the overall development of your baby, as it contributes to the muscle mass (6).

Fiber helps prevent irritable conditions such as constipation and fatigue, keeping you active and ready for a smooth delivery (7).

4. Iron promotes hemoglobin levels

Your body requires more hemoglobin as the volume of the blood increases during pregnancy. Mushrooms are an excellent source of iron, which helps produce hemoglobin and red blood cells in both the mother and the fetus (8).

5. Antioxidants boost the immune system

Antioxidants (selenium and ergothioneine) present in mushrooms boost the immune system (9) and keep you disease-free and healthy during pregnancy. Mushrooms also contain zinc, potassium, and selenium, which assist the baby’s growth and development.
