Food preferences changing during pregnancy

Hi all,
I’m super excited to be 5 1/2 weeks pregnant!! Becoming pregnant was my motivation for recovery and so this is a huge success for me that all my hard work and body changes have paid off. Prior to getting pregnant, I’d found a pretty happy place with my diet. I did eat a lot more initially and take a break for exercise completely. My hormones were horrible and I didn’t have my period so this was necessary for me. Then after about 3 months I found drawn to more fruits, veggies, meats, eggs, etc. I made sure I ate carbs with every meal because I know my body needs them but I was getting them from fruit, sweet potatoes, potatoes, squash, etc. I ate grains if I wanted them but didn’t want them so much.

Now that I’m pregnant I do not want eggs or meat and only want grains pretty much. I did eat meatloaf and mashed potatoes a few days ago and last night had fish tacos but overall my tastes are so different. Especially since I’m nauseous in the morning and on and off throughout the day.

My worry is that I’m not eating “optimally” and not giving my developing baby the best nutrition. At home I have the best quality ingredients and I think just eating what I want is more important. I avoid PUFAs and eat what would usually be considered a “healthy” pregnancy diet but often I feel like I should be eating a more paleo/primal way of eating so my baby could get the best nutrition. I guess I’d just like some reassurance that what I’m doing is the best for me and my baby. With my first pregnancy (7 years ago) I was a vegetarian and ate whatever I wanted and had a very healthy pregnancy and perfect baby so that’s what’s reassuring me. I just wish I would erase all of the paleo/primal/nutrition books I’ve read since then!
