There are certain things you should avoid consuming when you are pregnant, including:

1. Alcohol

No level of alcohol has been determined as safe during pregnancy, so avoid drinking alcoholic beverages while you are pregnant.

2. Fish with high levels of methylmercury

Avoid eating shark, swordfish, king mackerel, and tilefish while pregnant, since these fish have high levels of methylmercury, which could harm your baby. You can safely consume up to 12 ounces of fish that is lower in methylmercury (e.g., shrimp, canned light tuna, salmon, pollock, catfish). Eat no more than six ounces of canned albacore (white) tuna or tuna steaks per week.

3. Soft cheeses and cold lunchmeats, hot dogs, and deli meats

Soft cheeses (e.g., Brie, feta, Camembert, Roquefort, Mexican-style soft cheese) and cold lunchmeats, hot dogs, and deli meats can contain bacteria that can harm your unborn baby.

4. Raw fish, meat, or poultry

These foods can result in food poisoning that may cause harm to your baby.

5. Caffeine

You should also limit your intake of caffeine, which has been associated with an increased risk of miscarriage. Most healthcare professionals believe that a cup or two of coffee per day will not harm your baby, but since some studies suggest that even small amounts of caffeine may be harmful, it is best to avoid caffeine altogether.

If you are a vegetarian, are lactose-intolerant, or have other dietary restrictions, consult your doctor or a dietician, who can help you plan a well-balanced, healthful diet to fit your lifestyle and needs.

Nonfood items to watch

Some pregnant women crave nonfood products, such as cornstarch or clay, a condition called pica. You should avoid consuming these things and tell your doctor if you are having cravings for nonfood items.
