Ranking Seafood: Which Fish are Most Nutritious?

Fish are most nutritious

The Most Nutritious Fish

When you’re deciding what kind of fish to buy, ask yourself, “What’s the main nutrient I’m trying to get from this food?” What nutrients can you get from this food that you can’t get as easily from others? For fish, the most valuable nutrient status would probably go to omega 3 fatty acids. For this reason, we have placed the fish containing the most omega 3 fatty acids at the top of the list and thus the most nutritious fish.

These are not necessarily the fish that are the lowest in fat. Note that when you choose one fish over another, you’re making some tradeoffs. Some of these are small and insignificant; if you eat dairy products regularly, you don’t need to worry about how much calcium is in your fish. Other choices matter more: mackerel, for example, contains a high amount of omega-3 fatty acids, but it also derives half of its overall calories from fat, including saturated fats. You would do better choosing salmon or tuna unless you’re on a tight budget. Here’s how fish rate according to different nutrients.

Which DHA Supplement is right for me?

Another way to consume vital nutrients from fish is through supplements. With a variety of delivery methods, parents have a better chance of finding a solution that works best for their child ensuring the child is likely to take the product on a daily basis without fuss. Some children prefer liquid oil, similarity, others might prefer swallowing or “popping” soft gels. For others, the fruit chews are their favorite.
