Alcohol: You should not drink beer, wine, liquor (such as whiskey or gin), or any other mixed drinks. Drinking alcohol can increase your risk of having a miscarriage (losing your baby). Your baby may also have health problems such as being born too small and having learning problems.
Caffeine: It is not clear how caffeine affects pregnancy. Limit your intake of caffeine to avoid possible health problems. Caffeine may be found in coffee, tea, cola, sports drinks, and chocolate.
Foods that contain mercury: Mercury is naturally found almost all types of fish and shellfish, and is not harmful to most people. However, some types of fish absorb higher levels of mercury that can be harmful to an unborn baby and young children. During pregnancy it is important to carefully select the kind of fish that you eat. You should avoid certain types of fish, and eat fish and shellfish that are lower in mercury.
Do not eat shark, swordfish, king mackerel, and tilefish.
You may eat up to 12 ounces of fish or shellfish that have low levels of mercury each week. These include shrimp, canned light tuna, salmon, pollock, and catfish. Because albacore tuna has more mercury than canned tuna, eat only 6 ounces of albacore (white) tuna per week.
