I am craving for instant mee however many have said its damanging to baby. Is this true?

I ate quite a lot of cup noodles cos I was pregnant when in China and the cup noodle was the most convenient lunch place. My baby was overweight and have eczema (though of course, there's no study linking instant noodles to eczema) but still fast food has been linked to more severe eczema, so better eat healthy!
