Are there any disadvantages to swordfish?

 

Swordfish can add many benefits to your diet. However, one major drawback is that it contains high levels of mercury. Mercury is a reactive heavy metal that is mainly produced by the burning of waste and coal, with mercury waste from these activities reaching lakes and oceans via rainwater.

Small aquatic organisms absorb mercury, which is then passed on to larger predators when they feed on them. In this way, mercury is passed down the food chain from prey to predator. Larger, longer-lived predators, such as swordfish, tend to have higher levels of mercury.

Mercury is a neurotoxin that negatively affects the brain. People who consume large amounts of predatory fish (more than five servings per week) are at greater risk. In addition, mercury intake may reduce the heart health benefits of omega-3 fatty acids. Mercury is a particular risk to the development of the central nervous system in children. Research suggests that mercury can cross the placenta or be passed to babies through breast milk. Pregnant and breastfeeding women are advised to avoid eating swordfish.

**How ​​to Cook Swordfish**

 

Swordfish has a rich flesh, a slightly sweet flavor, and a firm texture. It can be prepared with or without a marinade, and people often prefer to use oily marinades that include fresh herbs. It is usually cut into 1-inch (2.5-cm) thick slices and can be grilled or cooked in the same way as raw beef steaks. Although some avoid eating the skin because of its rubbery texture, you can keep it on during cooking and then discard it later, which helps make the fish more juicy. Other common cooking methods include boiling and braising, as the tough texture of swordfish prevents it from flaking or breaking. Although frying swordfish is not common, it is a possible method of preparation, but be aware that fried foods can lead to the formation of trans fatty acids (TFAs), which increase the risk of heart disease.

**Cons**

Including swordfish in your diet can offer many benefits, but it has a major drawback: it contains high levels of mercury.

Mercury is a reactive heavy metal, and is often generated from waste and coal burning. The mercury waste from these activities ends up in lakes and oceans through rainwater.

Small aquatic organisms absorb mercury, which is then passed on to larger predators through their consumption. In this way, mercury travels through the food chain from prey to predator. Larger, longer-lived predators, such as swordfish, tend to have higher levels of mercury.

Mercury is a neurotoxin, which has toxic effects on the brain. People who eat large amounts of predatory fish—more than five servings per week—are particularly at risk. Eating mercury may reduce the heart-healthy benefits of omega-3 fatty acids.

Mercury also poses a particular risk to the development of the central nervous system in children. Research suggests that mercury can cross the placenta or be passed on to babies through breast milk. Pregnant and breastfeeding women should be cautious.

**Side Effects and Allergies**

Swordfish is rich in essential nutrients and offers a number of health benefits. However, there is concern that it may contain high levels of mercury.

Swordfish, being predators, feed on a variety of other fish, which leads to the accumulation of large amounts of mercury, especially methylmercury. This toxin can cause cancer and negatively affect brain health.

Fish that live for long periods and are at the top of the food chain (apex predators) have higher levels of mercury thanWith other species. Regular consumption of these fish can lead to mercury poisoning. Although the body naturally eliminates methylmercury, it can take more than a year for levels of this element to decrease significantly. Therefore, the Food and Drug Administration and the Environmental Protection Agency (EPA) recommend that pregnant women, nursing mothers, and young children avoid eating these types of fish.

There is no need to worry. Most sea fish contain some methylmercury. Rather than abstaining from them completely, it is better to reduce their consumption. Be sure to consult your doctor before making any decisions. Swordfish is a large predatory fish with unique nutritional properties, as it is rich in selenium and omega acids.
