Whether you love or loathe it, there is one obvious thing about fish; it is healthy for the body. However, many people don’t consume enough. Let’s dive straight into the essential facts you need to know about fish.


Eating fish comes with plenty of benefits. On top of being a good source of protein, fish contains essential fatty acids (particularly oilier fish), and vitamin D. Proteins are helpful in repairing damaged body tissues and building muscles. Vitamin D keeps your bones healthy, while omega-3 fatty acids aid in brain and cardiac health.

Fish Can Have High Levels of Omega-3 Fatty Acids

Now that you already know the importance of omega-3, you could be wondering which fish contain higher levels of this nutrient. Fattier fish like sardines, tuna, salmon, lake trout, and mackerel contain higher levels of omega-3, than other types of fish. However, you should not select fish based merely on omega-3 fatty acids; consider other nutrients too. Depending on your goals, it is important to switch things up, since some fish have lower levels of omega-3, but have incredible protein content.

Cholesterol in Fish

Yes, some types of fish can be a good source of healthy nutrients, but what about their cholesterol levels? Shellfish is a good example of fish with a notable cholesterol amount, even though it is a good protein source. Other seafood with high cholesterol levels includes crab, lobster, and shrimp.

How Often Should Fish be Eaten?

Now you know the benefits of fish, you should make the decision to include it in your diet plan on a regular basis. How often should you eat fish? The answer is simple; about eight ounces a week. This is according to the Dietary Guidelines of 2015. Avoid excessive consumption of fish. Consuming too many nutrients of a particular type may result in health issues. Eat in moderation!
