Pregnant? This is a good time to fine-tune your diet. Go for a more natural diet, and avoid processed foods as much as possible.
"Instead of hopping on the first diet you read about, take some time to listen to what your body is telling you. You may find that some of your favorite foods no longer appeal to you and that foods you've sworn off in the past now sound increasingly tasty. I like to think that cravings and aversions are your body's way of directing you to the nutrients it needs in the moment. If you've avoided specific foods in the past, you may want to grant yourself permission to eat these foods if your body is telling you it wants them."
Consider adding some supplements to your diet now that you are pregnant. A prenatal multivitamin, and omega-3 essential fatty acids are a good place to start, in this plan of yours to grow a healthy baby.
