Apparently protein and folates are good for TTc'ers. I just did a quick google search.

Go Heavy on Protein and Folates
Choose meals that include protein sources such as:

Fish
Poultry
Lean meat
Beans and lentils
Nut butters (such as peanut, almond, or cashew butter) as well as seeds and nuts
A generous portion of whole-grain products
Low-fat dairy products

Also look for foods rich in folates, such as:

Lentils
Oatmeal
Pinto and navy beans
Asparagus
Spinach
Orange juice


Say No to Artificial Sweetners
Although the scientific evidence is scant regarding the safety of artificial sweeteners and pregnancy, it's better to play it safe than to enter unknown artificial territory.

To please the sweet tooth, try these healthy alternatives:

Frozen bananas
Fruit smoothies
Naturally sweetened, nonfat frozen or regular yogurt
Low-fat, naturally sweetened sorbet
Fresh fruit
