I had this too at first, "back in my day we didn't worry about all of that", "I ate it and my kids are fine", blah blah blah! I don't know what they think they will get out of criticising, they wouldn't say anything if you just didn't like those foods or were allergic.

Good on you for doing what you can to keep yourself and your baby healthy, especially given that "back in the day" they didn't know about bacteria and things in food like the do now. Plus, who wants to risk food poisoning on top of pregnancy anyway!
