Now seafood is available all year round and not only at sea.
But are they so useful?
All seafood, without exception, is rich in protein, which is more in them than in meat, and it is much easier to digest. You can eat seafood without fear for the figure — 100 g contains from 60 to 120 kcal.
Seafood is high in polyunsaturated fatty acids, including Omega 3. They reduce the risk of cancer, improve brain function, strengthen the walls of blood vessels and reduce the level of harmful cholesterol in the blood.
In addition, seafood is a source of vitamins, minerals and trace elements. The easiest way to get them is to eat a sea cocktail. It usually includes shrimps, squid, mussels and octopuses. If you include it in your diet, you can cover the body's need for vitamins A, E and group B, iodine, calcium, iron, phosphorus, potassium, zinc and selenium
With a wide variety of species, all shrimps are a source of essential amino acids, vitamins of almost the entire B group, and trace elements. Shrimps contain a large amount of iodine, which is necessary for the normal functioning of the thyroid gland. Potassium, magnesium, and zinc support the cardiovascular system. Regular consumption of shrimps normalizes the metabolism, reduces the risk of developing allergies and cancer.
Shrimps also contain a large amount of cholesterol. Some call this cholesterol "bad" and call for the exclusion of shrimps from their diet altogether. Others claim that the cholesterol in shrimps is "good", and you can eat them without any restrictions. The truth, as always, is somewhere in the middle, so it is still not worth abusing shrimps
Squid meat contains a large amount of protein, vitamins and trace elements. The combination of proteins and polyunsaturated fats promotes the development of muscle fibers. In this regard, the squid is very popular among those who want to build muscle mass. Squid meat contains vitamins B6 and B3, which improve the metabolic processes in the body, improve the functioning of the gastrointestinal tract. Squid contains a lot of potassium, which removes excess fluid from the body, and selenium, which removes heavy metal salts.
However, all the useful properties of fresh squid are not transferred to dried squid. They contain a lot of salt, which retains fluid in the body and causes swelling
The mussel is an amazing clam. In terms of their nutritional properties, mussels are in no way inferior to oysters. Only they are much cheaper, and they have fewer calories.
Mussel meat contains a large amount of vitamin B12, which in turn helps to better absorb other vitamins, as well as minerals and trace elements. And there are a lot of them in mussels - vitamins A, E, C and group B, iron, manganese, phosphorus, potassium, zinc, iodine and selenium. 100 g of mussels contains 13% of the daily value of vitamin C, 22% of iron and 52% of selenium. Selenium is undeservedly ignored, and yet with its deficiency in the body, iodine is not absorbed.
In addition, mussels are low in cholesterol and high in phospholipids, which have a beneficial effect on the liver.
There are no obvious disadvantages in mussels
If you do not live near the sea, it is better to buy frozen seafood. First, they are fresh only on the day of the catch. Secondly, without proper treatment, small parasites that live in seafood can remain, and which may well get into our body. Shock freezing at temperatures below-40 °C kills the larvae, while preserving the useful properties of the product. When buying, only pay attention to the amount of ice in the package. It should be at least! A lot of ice means repeated re-freezing of the product. White spots on the shell are also a bad signal: the shrimps were repeatedly thawed
