Hi everybody!

I’m translating the article about pike and I'm eager to make my work better.  Could you, please, check the following passages? Does it sound good? Do I need any improvement? I appreciate your help.

Since long, people have recognized fish for its high nutritional qualities and amazing taste. Fish proteins have high biological value and even exceed meat proteins in terms of some characteristics. In fact, fish proteins are easier to digest. Yet caloric value of fish is somewhat lower than that of meat.

That’s why those who care about their weight should get more fish into their diet. Fish oil is healthy and is a rich source of vitamin A and essential polyunsaturated fatty acids. Spike dishes provide us with lots of proteins that promote our health. Pike is a freshwater predator fish, and it contains less than 4% of fat. That’s why pike flesh is considered a dietary one.

Physicians recommend fish to patients with digestive disorders and thyroid gland disease. The others, however, will only benefit from eating more fish. Fish as well as chicken is one of the best sources for high-quality protein. Any fish has a high content of trace elements like kalium, magnesium and especially phosphorus. Fish is also a good source of the B vitamins.

Regular consumption of baked fish or fish fried over open fire can help reduce the risk of arrhythmia. Scientists say that fish contains fatty acids. These acids have heart health benefits and promote brain function. Pike has white tender flesh and a few bones.

Thanks in advance
The organisation of this article seems a bit random in places.

[this kind of makes it sound as if there's some doubt about whether they do or don't]. These acids have heart health benefits and promote brain function. Pike has white tender flesh and a few bones [do you mean "has few bones"?].
Thank you very much!!!!
