23 Fish With The Highest Protein Content (Ultimate List)

Protein is the source of a major portion of your body’s energy. Protein is found in all of your cells and tissues of the body, so eating enough of it is essential not only for normal development and repair but also for maintaining good health.

It’s the second most common component in the body after water, which provides around 15% of your nutritional energy.

Now, based on the recommended dietary allowance (RDA), you’re looking for a moderate 0.8 grams of protein per kilogram of body weight.

Though this may seem like a lot, it’s readily achievable with some more seafood in your diet.

You’re probably not eating enough fish for whatever reason. Perhaps you might dislike the way it smells when you prepare it or maybe you don’t like how fishy it tastes.

Maybe you have a personal intolerance to fish. But let me tell you that you’re not alone if you have issues regarding fish.

It is estimated that Americans, (in particular), consume only 15 pounds of fish and shellfish each year. According to the National Chicken Council, they consume a remarkable 91 pounds of chicken per year.

Well, there’s nothing wrong with chicken other than the fact that eating the same thing, again and again, will make you feel bored.

Getting over your fish concerns offers far-reaching advantages that go beyond taste. Fish protein is easily digestible, delicious, and high in omega-3 fatty acids. Omega-3 fatty acids are beneficial for our mental wellness.

Because most other protein food sources do not provide the complete protein as fish does, fish is an excellent choice if you are seeking ways to achieve appropriate protein consumption via your diet.

Also the two necessary amino acids, Lysine and Isoleucine, which cannot be synthesized by the body and must be absorbed through food, are present in fish in their entire form and therefore fish delivers protein in its purest form.
