I have never been pregnant but I don't imagine I will have any issues with food -- I have ALOT of women in my family and I don't know that any one of them had cravings or aversions to certain foods.
The only thing my mom ate alot of was ice cubes and iceburg lettuce but she claims it's because she thought extra water was good and iceburg lettuce was the only raw veggie she enjoyed, and she wanted to eat veggies while pregnant.
I really hope I don't crave anything unless it's healthy, and I hope I don't get sick from anything unless it's something I really shouldn't eat while pregnant lol. I try to eat very healthy in general, but I will be even more so when pregnant. All organic, tons of vegetables and fruits, whole grains, etc. I don't have a husband or anything so it's silly for me to plan, but I still always look up what foods to eat during pregnancy because it's something that interests me and I really want my baby to be healthy. I can't wait.
