You’ve probably heard that fish is good for your health. But like many people, you may have wondered:
What exactly makes fish so beneficial?
In this guide, we’ll break down the nutritional value of fatty fish—and address a common concern many people have: mercury exposure.
Is Mercury Poisoning Something to Worry About?
When people think about eating fish, one concern often comes to mind: mercury. If that’s something you’ve worried about, you’re not alone.
In recent years, mercury in seafood has become a widely discussed topic, leading some people to limit or avoid fish altogether. But the reality is more balanced.
Most fish contain small amounts of mercury, usually in the form of methylmercury. However, these levels are typically low, and for the average person, normal fish consumption does not pose a health risk. Mercury-related health issues are generally linked to frequent, long-term consumption of large amounts of high-mercury fish, not occasional meals.
There’s also an important factor many people don’t hear about: selenium. Fish naturally contain this essential mineral, which can bind to mercury and help reduce its potential impact on the body. While this doesn’t completely eliminate mercury risk, it does provide a layer of protection.
The Health Benefits of Eating Fish
Fish is an excellent addition to a balanced diet. It offers:
-
High-quality protein
-
Essential nutrients
-
Low saturated fat
-
Omega-3 fatty acids, which support heart and brain health
Fatty fish in particular are one of the best natural sources of omega-3s—often referred to as “healthy fats.”
For children and pregnant women, fish can play an important role in growth and development. That said, these groups should be more selective about the types of fish they eat. It’s best to:
-
Avoid large predatory fish like shark and swordfish
-
Limit fish intake to about two servings per week
The Bottom Line
For most people, fish is a safe and highly nutritious food that should be included regularly as part of a healthy diet.
Rather than avoiding fish altogether, the key is to choose a variety of seafood and consume it in moderation—allowing you to enjoy the benefits while minimizing any potential risks.
