Do: Fruits and Vegetables
As important as fruits and vegetables are to the nonpregnant person, they're even more so to the pregnant woman.
The vitamins, minerals and antioxidants provided by things like strawberries, spinach and sweet potatoes are a crucial part of any pregnancy diet. The options for getting the minimum five to six servings a day (combined) are endless. For vitamin C (oral health and bone growth), look to oranges, strawberries, broccoli or tomatoes.
For folic acid, a B vitamin required in high quantities (at least 0.4 milligrams a day) for blood and protein production and to reduce the risk of neural-tube defects like spina bifida, look to leafy greens, peas and dark yellow fruits and veggies (along with legumes, veal and fortified cereals) [sources: WebMD, BabyCenter].
For vitamin A (eyesight, healthy skin and bones), sweet potatoes, spinach and sweet potatoes are excellent choices.
That's just the beginning of the variety of vitamins and minerals that should be incorporated into a pregnancy diet. For a complete list, look at KidsHealth: Eating During Pregnancy.
