For pregnant women, eating fish can be a healthy choice, as it provides essential nutrients such as omega-3 fatty acids, protein, and vitamins.

However, certain types of fish can contain high levels of mercury, which can be harmful to a developing fetus.

Mercury in Fish

Mercury is a toxic metal that can affect the nervous system, brain, and kidneys. Pregnant women are particularly vulnerable to the effects of mercury, as it can pass through the placenta and harm a developing fetus.

Fish absorb mercury from the water they live in and the food they eat. Larger species of fish, such as shark and swordfish, tend to have higher levels of mercury because they eat smaller fish that have already accumulated mercury in their bodies.

Fish to Avoid

Pregnant women should avoid the following types of fish, as they are known to contain high levels of mercury:.

Shark

Shark is a type of fish that should be avoided by pregnant women due to its high mercury content. It is commonly found in fish and chips, and also used in sushi and other dishes.

Instead, pregnant women should choose other types of fish that are lower in mercury, such as salmon or trout.

Swordfish

Swordfish is another type of fish that contains high levels of mercury and should be avoided by pregnant women. It is often used in grilled or fried dishes and is also found in sushi.

While fish can provide important nutrients, it is important to choose lower-mercury options and limit intake to 2-3 servings per week.
