For greens, I do green smoothies. I've been doing them for over a year now so it might not be something you want to start when you're feeling sick. (Drinking a grainy green concoction may not work for everyone.) I invested in a Vitamix and it's made all the difference. I have a green smoothie for breakfast and it gives me a bit of energy and makes me feel full until my next breakfast meal in an hour. Right now, I'll have a mixture of kale, chard, spinach, dandelion greens, collard greens, etc., with a splash of pineapple juice, water, frozen berries, and banana. Recently, I tend to load up on the fruits so that it overpowers the green taste, and it helps. The smoothies also kinda help to keep things ahem, regulated, so I'm hoping I don't experience pregnancy constipation down the road. Green for Life is an awesome book for anyone looking to get more greens. It goes into detail on how your teeth aren't sufficient at masticating and breaking down the fibers of greens to receive optimal nutrients...so by blending, the nutrients are much easier to absorb and are instantly absorbed into the blood stream upon consumption. The health benefits are amazing. Initially, I lost almost 30 lbs over the first 6 months of just having green smoothies for breakfast or a snack. It made such a difference in energy, etc.
Other than that, I've been eating a lot of cheese, and mixing it with anything whole grain I can get. Cheese sandwiches, cheese and kashi crackers, whole wheat bagels with cream cheese, and cheese on everything. Eggs I tend to eat hard boiled or scrambled on the weekend (with cheese of course). Citrus - clementines are delicious.
And for dinner, I've gotten some good recipes off of this website: http://babyfit.sparkpeople.com/pregnancy-recipes.asp?category=4 I tend to look for vegetarian dishes because a) I need to eat more vegetables and b) you can always add meat to any vegetarian dish.
Last night, I made stuffed zucchini with a side of pasta, which was really good. The other night was tortellini with vegetables, and of course, tons of rice and beans.
I used the Bradley nutrition diet as a guideline but there's no way I'm eating that much in a day (plus I don't really like a lot of dairy) http://www.bradleybirth.com/Diet.aspx
In the past, I've had a few digestion-related issues, so I really pay special attention to food combining for proper digestion. So, if I'm eating meat, I don't eat starches in the same meal. Starches are eaten with vegetables. And vegetables can be combined with anything. This REALLY helps me feel healthy full without feeling lethargic or even worse, like stuff is just "sitting" in my belly.
I've been lucky so far in that my appetite hasn't gotten really funky and I'm not experiencing any nausea. Other than the jar of olives I downed the first week we thought I might be pregnant, no other weird food cravings either.
I've got a handle on nutrition - now I just gotta get working on exercise component...
