CERTAIN FISH
Though many people see fish as a good, clean source of protein and nutrients, such as fatty acids, the type of fish a pregnant person eats is very important. Some fish tend to be high in mercury, which is very toxic and causes problems for both the pregnant parent and the fetus. pregnant women should avoid big eye tuna, marlin, and swordfish.
RAW SHELLFISH
While pregnant, it is best to avoid all raw seafood, especially raw shellfish. Raw shellfish, such as oysters, crab, and clams, may be a potential source of Vibrio bacteria, which can cause cholera and other infections.
RAW OR UNDERCOOKED GREENS AND SPROUTS
Greens and sprouts are generally great foods to add to the diet as they contain large amounts of fiber and nutrients. However, some greens or sprouts may contain bacteria, such as Salmonella or E. coli, which can cause infection.
RAW OR UNDERCOOKED EGGS
Eggs are a simple source of protein and nutrients, but undercooked or raw eggs may contain Salmonella bacteria.
SOFT CHEESE
Many kinds of cheese contain helpful bacteria, but some contain harmful bacteria as well. Pregnant women should avoid soft cheeses made from unpasteurized milk.
CAFFEINE
While some people can enjoy a small amount of caffeine during pregnancy, doctors often recommend that pregnant women avoid it completely because caffeine can pass to the fetus.
UNPASTEURISED MILK OR FRUIT JUICES
Pregnant women should avoid both unpasteurized milk and unpasteurized fruit juice. Unpasteurized milk may contain E. coli, Listeria, or Salmonella. These bacteria can cause severe infections in pregnant women, especially if their immune system is already stressed.
