Fish is a great source of protein and omega-3 fatty acids, which offer numerous health benefits, including reducing the risk of heart disease, stroke, and dementia.
However, as with any food, eating too much fish may also have negative consequences. Fish can contain pollutants like mercury and PCBs (polychlorinated biphenyls), which can accumulate in your body over time, potentially causing harm.
Therefore, it is important to know how much fish you can safely eat in a week.
How Much Fish Can You Eat?
The amount of fish you can safely eat depends on the type of fish you consume. The Food and Drug Administration (FDA) recommends that adults eat 8-12 ounces of fish per week, which is equivalent to two to three servings.
However, some types of fish contain higher levels of contaminants than others, and it’s important to be mindful of this when deciding how much fish to eat.
Which Fish Should You Avoid?
The FDA and Environmental Protection Agency (EPA) have issued guidelines to help consumers choose fish that are low in contaminants. They recommend avoiding certain types of fish altogether.

How to Prepare Fish Safely
The way you prepare fish can also affect its safety. Here are some tips for preparing fish safely:.
- Cook fish thoroughly. Cooking can help reduce the level of contaminants in fish. Make sure to cook fish to an internal temperature of 145°F.
- Trim the fat. Contaminants can accumulate in a fish’s fatty tissues, so trim off any visible fat before cooking.
- Avoid raw fish. Sushi and sashimi may contain raw fish that can increase your exposure to contaminants.
- Choose wild-caught fish over farmed fish. Wild-caught fish are generally lower in contaminants and have a more diverse diet than farmed fish.
- Use caution with canned fish. Some canned fish, like albacore tuna, may contain higher levels of mercury than other types of fish. Make sure to check the label and choose lower-mercury options when possible.
- Be aware of fish during pregnancy. Pregnant women should talk to their healthcare provider about which fish are safe to eat and how much they can consume.
Conclusion
Fish is a healthy and nutritious food, but it’s essential to be aware of the potential risks associated with consuming certain types of fish.
By following the FDA and EPA guidelines, you can safely enjoy the many health benefits of fish while minimizing your exposure to contaminants.
