Nope, never heard that. If you listened to every "bad for you in pregnancy" recommendation, you'd have serious malnutrition.
|One last thought: never eat raw mushrooms, even the store-bought button mushrooms, so often found served raw in salads or on vegetable platters. All mushrooms have natural pesticides in them. These get cooked out of most edible mushrooms. Some edible mushrooms, like the morel, may make you very sick if eaten raw. Other raw mushrooms may build up toxins in your system over a period of time. Our advice is to not eat raw mushrooms, even if you've never had a problem in the past.|
