The most delicious fish - what is it?
In a dispute about which fish is the most useful, you can rely on the research of scientists: they carefully calculated the content of vitamins and microelements in each type of fish, accurately determined the beneficial properties of fish. It so happened that the river fish is more accessible than the sea. Most of us have tried to catch her on the river or lake. However, in terms of nutritional value and nutrient content, sea fish is still healthier. This is due to the conditions of its cultivation - sea water is much richer in trace elements and food supply than water in fresh water, which affects the beneficial properties of fish.
The most useful fish is how to determine it.
The biggest advantage of sea fish over the river is the high protein content in it. If in ordinary river fish the amount of protein barely reaches 20%, then in the marine this figure can reach 26-28%. It contains all the essential fatty amino acids and is absorbed much faster and easier. Fat varieties of sea fish are very useful for stimulating cerebral circulation. Also in sea fish are a lot of vitamins A, D, group B, a whole complex of trace elements - nicotinic acid, phosphorus, bromine, sodium, iodine. We can confidently say that the most useful fish is sea fish.
In freshwater fish, some of these elements are missing. However, in some diseases of the body it can be useful in case of disorders of the urinary system and kidney diseases, some diseases of the nervous system. However, there are recipes for fish dishes for which only river fish is suitable, as it has a special taste.
Fish dishes must be included in the diet, it is especially important to get good nutrition for children - with a lack of necessary microelements in the body, they have a lag in growth and physical development, the beneficial properties of fish will help to avoid this.For the elderly, the amino acid taurine, which is also found in fish and seafood, is important because it serves as a blood pressure regulator and stimulates insulin production. Its presence in sufficient quantities in the body inhibits the development of hypertension and diabetes. If you know how to cook a tasty fish, there is no reason to argue about which fish is the most delicious.
Do not neglect the recipes of fish dishes, include them in your diet!
Tip 3: Which fish has the biggest liver
All about the giant shark
In size, the giant shark is inferior to the whale shark, but its dimensions are more than impressive - it has an average length of 10 meters and a weight of 4 tons. This species lives in moderately warm waters of the Pacific and Atlantic oceans. Externally, the body of a giant shark resembles a cigar of dark gray, brown or black. The belly of the fish has a lighter color than the sides and back, and the muzzle is far ahead.
In young giant sharks, the muzzle is similar to a short trunk, which disappears with time, transforming into a full-fledged shark muzzle.
On both sides of the head of the shark are huge gill slits, which have no analogues among other fish. Gill arches of a giant shark are equipped with 1000-1300 smallest horny stamens each - their purpose is to filter sea water. Since this type of shark feeds only on plankton, their teeth are microscopic (compared to body size) and are located in 5-7 rows. They shark literally rubs plankton.
Giant shark liver
The liver of a giant shark is located at the back of the body and makes up almost a quarter of the shark's body mass. This allows it to act as a kind of float that does not allow the shark to drown. It is supported by two powerful pectoral fins, and the shark controls the movement of the body by a symmetrical tail fin. The liver of a giant shark is surprisingly useful - it contains a huge amount of vitamins A, D and E, and also squalene is a substance used to treat lung, heart, female and skin diseases.
Today, scientists are engaged in the development of drugs from squalene, which will help treat cancer.
In addition, the liver of a giant shark contains alkyl glycerides and fatty acids, which are the most valuable natural raw materials for food supplements and medicines. These substances strengthen the immune system in all directions, and squalene and squalamine help to effectively fight bacterial and fungal infections.
Shark liver is called a nutrient factory - and not just nutrients. Shark liver oil was used in the 18th century, when Norwegians and Swedes used it to heal wounds and treat diseases of the digestive and respiratory systems. The ancient Spaniards, who regularly drink this oil, knew about the benefits of shark liver - they practically did not get sick and did not even know what a cold was.
