6 ways to protect your baby and yourself from harmful, overprocessed foods and make your prenatal diet as safe and natural as possible
Even if you typically eat a fairly healthful diet, pregnancy requires some adjustments. You need extra nutrients to keep up with the demands of your changing body and growing baby, and you should avoid certain foods altogether. This doesn't mean you must follow a stringent regimen--or deny yourself--but it does mean giving a little extra thought to your food choices.
By this, we mean eating foods that are minimally processed and contain few or no additives, preservatives, pesticides, hormones or other chemicals. "When you eat unadulterated foods, you're getting 100 percent of the food's nutrition--nothing has been taken out and nothing is put in," says Dawn Jackson Blatner, R.D., L.D., a national media spokeswoman for the American Dietetic Association in Chicago.
These six guidelines, adapted from The Whole Pregnancy Handbook by Joel M. Evans, M.D., and Robin Aronson (Gotham Books, 2005), will help you clean up your eating habits. Then follow the three-day meal plan. Created by Robin Miller, host of the Food Network's Quick-Fix Meals With Robin Miller, its goal is optimum health for you and your baby.

6 simple ways to detox your diet
1) Choose brown rice and whole-grain pastas and breads instead of white. When a whole grain is processed, it's stripped of fiber and precious phytochemicals that boost immunity and help prevent disease. Whole grains are the good carbs, especially for pregnant women. The fiber they provide sustains your energy longer than refined grains do and helps prevent constipation, a common problem during pregnancy.
2) Opt for organic fruit and vegetables when you can. "Organic produce is often more expensive," admits Ted Schettler, M.D., M.P.H., science director of the Science and Environmental Health Network and co-author of In Harm's Way: Toxic Threats to Child Development (Greater Boston Physicians for Social Responsibility, 2000). "On the other hand, several studies show that if you eat organics, you have lower levels of pesticides in your blood."
Because of a unique developmental window of vulnerability, fetal and childhood exposure to many chemical contaminants is more dangerous than exposure later in life, Schettler says. "Avoiding neurotoxic pesticides is obviously a good thing for a growing brain, whether it's a fetus or a child," he adds. If you can't find or afford organic foods, make sure you wash your produce well. For more information, read "Contaminants on your plate" in "Clean House".
Equally essential is filling your grocery cart with produce in every color of the rainbow. Fruit and vegetables contain important nutrients for proper fetal development, such as calcium, fiber and iron, to name a few; each color offers different nutrients and protective properties. The deeper the color, the more nutrients you get.
For example, sweet potatoes and yellow peaches provide more carotenoids--a class of phytochemical that's vital for fetal development--than white peaches or potatoes. Deep green romaine lettuce has more vitamin C and folate (which protects against neural-tube defects such as spina bifida) than iceberg lettuce, its paler cousin.
3) Limit foods that are high in salt. Salt intake and water retention go hand-in-hand, especially when you're pregnant. For some women, high sodium intake may lead to potential pregnancy complications, such as high blood pressure. High-salt foods are, by and large, those that are highly processed: canned soups, frozen dinners and boxed grain dishes. Processed foods are generally higher in the ingredients you don't want more of--fat, sugar, salt and calories--and lower in important nutrients and vitamins.
4) Avoid foods made with chemical additives. Although most chemical food additives (such as artificial colors, flavors and refined sugars) are believed to be safe for a developing fetus, why take the chance? Foods made with chemicals are typically not your most nutritious or wholesome choices.
Artificial sweeteners, for instance, are approved by the U.S. Food and Drug Administration, but some nutrition experts advise pregnant women to stay away from them. They believe not only are chemical additives unsafe for the fetus once they cross the placenta, but they also can cause stomach problems, migraines and insomnia in adults (pregnant or not). Basic rule of thumb: The more unpronounceable additives you find in a food's ingredient list, the less nutritious it is--for both of you.

5) Eat grass-fed and hormone-free meat and poultry. Protein is the building block of everything in the body, from DNA to neurotransmitters (brain chemicals) to muscle--and during pregnancy, you need a variety of protein-rich foods. One good source is hormone-free meat and poultry. "The use of anabolic hormones is supposed to be carefully regulated, but in fact, those regulations are not always followed," Schettler says. "There are reports of measurable residual hormones in meat." Visit certifiedhumane.com/where.asp to find a retailer of hormone- and antibiotic-free meat in your area.
You also can get protein from beans, nuts, grains, legumes and soy products. If you don't eat red meat, one of the best sources of iron, be sure to consume other iron-rich foods, such as iron-fortified cereal, dried apricots and figs, blackstrap molasses and quinoa.
6) Be careful what you fish for. Fish contain omega-3 fatty acids, an important nutrient for both mom and baby's heart and immune health and baby's brain development. But many fish are contaminated with mercury, toxic industrial compounds (such as PCBs) and pesticides, substances that can cause problems ranging from brain and nervous system damage to cancer. Safe fish choices for pregnant women include farmed trout or catfish and wild Alaskan salmon and halibut. If you don't eat fish, you can get omega-3s from walnuts and ground flaxseed; sprinkle them on cereal or yogurt.
Water: Bottled vs. Tap
Pregnant women should drink 3 liters of water a day (equivalent to about 13 8-ounce cups), according to the Institute of Medicine of the National Academies, a Washington, D.C.-based nonprofit organization that gives science-based advice on health and other topics. But does it matter where the water comes from?
The Natural Resources Defense Council, a nonprofit environmental action organization, maintains there is no assurance that bottled water is any cleaner than tap. To investigate what's in the tap water in your area, contact your local health department. To check the purity of a particular brand of bottled water, visit the NSF International website at nsf.org.
What is essential is that you opt for water over other drinks most of the time. Although juice can be an excellent source of folic acid, it also is high in sugar and most are devoid of fiber. When you do drink juice, avoid those sweetened with sugar or high-fructose corn syrup (empty calories); choose 100 percent fruit juice instead.
