It's perfectly safe to eat if you can lol I don't like it much unless I forget my prenatal and iron is low. Then I crave a big juicy medium rare hunk of meat. Haha
Who told you, your vegetarian best friend? Seriously, do eat it if you ever eat meat. It is a great protein source and as mentioned, the iron is very important. Just cut out the steak tartare.
It is recommended to eat red meat for the iron. Just make sure it is fully cooked.
It's safe and good for you your body needs extra iron when pregnant. Just stick to 3 ounce low fat servings
