What is fish good for?

The greatest value of fish is that, in addition to vitamins and iodine, it contains polyunsaturated fatty acids (omega-3 and omega-6), easily digestible protein.

That is why nutritionists advise to eat fish at least twice a week.

Fish is rich in vitamins (A, E, D), calcium, zinc, selenium, iron, phosphorus, magnesium.

Thanks to this composition, fish is useful for the joints, brain, and the entire human body.

It slows down cell aging, stimulates reproductive function, and lowers cholesterol.

Which fish is more useful - sea or river fish

If you ask: which of the fish is more useful, sea or river, the vast majority will answer - sea.

But few people would say that it is a fish caught in wild conditions.

Sea fish wins over river fish in the presence of fatty acids, but river fish has more protein and iron.

But in order to deliver sea fish to the shelves, it is usually frozen more than once, so it loses some of its useful properties. 

Why not river fish?

Because rivers flowing near human settlements are catastrophically polluted.

Of course, the state of the seas and oceans is also disappointing, but there, harmful substances are mostly concentrated along the coastline.

And fishing is conducted in deep water, far from the shores.

But the fish on store shelves, even sea fish, is grown on farms where substances, growth stimulants, dyes, antibiotics, hormones, etc. are used for fattening.
