Swordfish is a popular fish that is known for its meaty texture and rich flavor. However, you may be wondering whether swordfish is good for you or not. The answer to this question is not straightforward, as there are both benefits and risks associated with eating swordfish.
On the one hand, swordfish is a good source of lean protein, vitamins, and minerals. It is also rich in omega-3 fatty acids, which are essential for heart health and can help reduce inflammation in the body. Additionally, swordfish is low in calories and fat, making it a healthy choice for those who are watching their weight.
On the other hand, swordfish is also known to contain high levels of mercury, which can be harmful to your health if consumed in large amounts. Mercury is a toxic metal that can damage the nervous system and cause other health problems.
As a result, it is recommended that you limit your consumption of swordfish to no more than one serving per month, especially if you are pregnant or breastfeeding.
