When women are pregnant, they should focus on eating healthy, well-balanced meals and snacks. That was a constant effort of mine but I had an additional concern. My husband has a peanut allergy and I was worried that my children would have the same. I had read that avoiding foods including peanuts and peanut products during pregnancy (and nursing) could reduce an allergy risk in susceptible children.
When I was pregnant with my first son, it was helpful to have a list of foods to avoid throughout my pregnancy (and even as I continued to breastfeed.) Here is a great list that I found on pregnancyinfo.com
Foods That Should Be Avoided During Pregnancy: (pregnancyinfo.com)
1. Raw Meat (rare meats may contain bacteria, toxoplasmosis and Salmonella, all of which are harmful to your unborn baby),
2. Deli Meats (those available at a deli counter, including hot dogs or turkey, beef and chicken preparations, should not be consumed unless you re-heat them until steaming. These preparations may be contaminated with a substance called Listeria. These bacteria can harm your baby severely, and may even cause miscarriage or result in a stillborn delivery. )
3. Imported Soft Cheeses: imported unpasteurized cheeses including blue cheese, feta, Brie or camembert should be avoided. These may also contain Listeria. However, soft cheeses that are made with pasteurized milk are safe to eat. It is important to check out the label. If you are not sure whether or not a product is pasteurized, you should generally avoid it.
4. Raw eggs or undercooked eggs (have the potential to contain Salmonella.)
5. Fish: While eating fish can be beneficial during your pregnancy, there are certain types of fish that you should avoid. These include shark, swordfish, king mackerel, excess tuna and tile fish, as all of these contain high levels of mercury, which can affect your unborn child’s nervous system. Canned tuna should also be avoided due to high levels of mercury contamination. Generally it is safe to eat 12 ounces of other fish including salmon and tilapia, which are full of nutritious benefits.
