The importance of fish in human nutrition
There are some foods that are simultaneously rich in iron, phosphorus, zinc, magnesium, calcium, selenium, vitamins A, E, D, and amino acids that are necessary for the normal functioning of the cardiovascular system, thyroid gland and stomach. But in fish, all these elements abound. Therefore it is very importance of fish in human nutrition.

Due to the fact that the collagen that makes up connective tissue, has the property of rapid transition in a soluble form, fish is easy to cook, and its tissues become loose, blagodaram provides maximum and rapid absorption of all nutrients. The most rich in protein fish include salmon, trout, and salmon, Beluga, easier to say that all representatives of groups of sturgeon and salmon. Great importance in human nutrition fish is also underpinned by a very high nutritional value due to high concentration of fatty acids. It refers to oily marine fish – salmon, mackerel, herring, trout, salmon and other things.
Polyunsaturated acids are the owners of great physiological activity, have a beneficial effect on intercellular processes, have anti-inflammatory properties, reduce the level of fat in the blood and help in reducing body weight.
Any fish is a valuable and affordable source of phosphorus, fluorine and iodine. The liver of most fish is rich in vitamins A, D and E. of Course, you need to consider that in case of long storage, freezing, drying, significantly reduced the nutritional value of fish.
The healing properties of fish

The result showed that those who several times a week eat fish from the sea, much less suffered from heart arrhythmia, than those who ate it once a month or even less frequently. Scientists explain the positive effect on cardiac work of those fatty acids, which we mentioned above. The researchers believe that, if we can convince people of the usefulness of fish can substantially reduce the incidence of arrhythmia.
In Europe also want to impress upon the people the notion of the beneficial properties of fish compared to meat. The results of studies conducted by the French, have demonstrated that people who eat fish are much less likely to suffer from bowel cancer than those of meat.

A similar effect is observed for other seafood, such as algae like seaweed.
The value of river fish
