Food and Drinks to Avoid During Pregnancy
As mentioned earlier, avoid alcohol. No level of alcohol consumption is considered safe during pregnancy. Also, check with your doctor before you take any vitamins or herbal products. Some of these can be harmful to the developing fetus.
And although many doctors feel that one or two 6- to 8-ounce cups per day of coffee, tea, or soda with caffeine won't harm your baby, it's probably wise to avoid caffeine altogether if you can. High caffeine consumption has been linked to an increased risk of miscarriage, so limit your intake or switch to decaffeinated products.
When you're pregnant, it's also important to avoid food-borne illnesses, such as listeriosis and toxoplasmosis, which can be life-threatening to an unborn baby and may cause birth defects or miscarriage. Foods you'll want to steer clear of include:
soft, unpasteurized cheeses (often advertised as "fresh") such as feta, goat, Brie, Camembert, and blue cheese
unpasteurized milk, juices, and apple cider
raw eggs or foods containing raw eggs, including mousse and tiramisu
raw or undercooked meats, fish, or shellfish
processed meats such as hot dogs and deli meats (these should be well-cooked)
fish that are high in mercury, including shark, swordfish, king mackeral, or tilefish
If you've eaten these foods at some point during your pregnancy, try not to worry too much about it now; just avoid them for the remainder of the pregnancy. If you're really concerned, talk to your doctor.
About Fish. Fish and shellfish can be an extremely healthy part of your pregnancy diet they contain beneficial omega-3 fatty acids, and are high in protein and low in saturated fat. But limit the types of fish you eat while pregnant because some contain high levels of mercury, which can cause damage to the developing nervous system of a fetus. Mercury, which occurs naturally in the environment, is also released into the air through industrial pollution and can accumulate in streams and oceans, where it turns into methylmercury. The methylmercury builds up in fish, especially those that eat other fish.
Because canned albacore (or white) tuna and tuna steaks are generally considered to be higher in mercury than canned light tuna, the U.S. Food and Drug Administration (FDA) recommends that you eat no more than 6 ounces a week. A 2006 review by Consumer Reports, though, showed that some canned light tuna can contain levels of mercury even higher than that of white tuna. But the FDA maintains that the levels are safe if consumption of the fish is limited, and that the current recommendations should stand.
It can be confusing when recommendations from trusted sources differ. But since this analysis indicates that amounts of mercury in tuna may be higher than previously reported, some women may want to eliminate tuna from their diet while pregnant or when trying to become pregnant. Almost all fish and shellfish contain small amounts of mercury, but you can safely eat those with consistently low mercury levels (like salmon, shrimp, clams, and tilapia). Talk with your doctor if you have any questions about how much and which fish you can eat.
