Currently, oysters arrive from France to Moscow in about a day. Before sending them, they are slightly cooled to a temperature of about minus 5 degrees. Sea delicacies are mined and artificially bred in some countries: in the USA, France, Portugal, Canada, Japan, Australia, Holland, Spain, Norway and the Russian Far East.

Definitely, this is a delicacy, but not everyone will like it. But, those who make this seafood a frequent guest on their dining table will get rid of numerous health problems.

General information about the treat

Before you get acquainted with the main beneficial properties of the delicacy, you need to understand what a living organism called an oyster is. It turns out that it belongs to the family of bivalves. The habitats of this group of aquatic organisms are warm marine reservoirs. Mollusks are common in the waters of the Atlantic, Pacific, Indian oceans, as well as along the coasts of some seas: Japan, Black, Mediterranean. The depth at which they can stay varies from one to 70 meters.

Oysters differ in the shape of the shells in which they live. The latter can be oval-wedge-shaped or irregularly rounded, concave or flat, large (up to 45 cm long) and small (no more than 12 cm). Accordingly, oysters also vary in size.

To date, the marine fauna is represented by fifty varieties of these marine mollusks. They live one at a time or in colonies, otherwise - oyster banks. I must say, the second option is much more common than the first. Oyster colonies happen to be several hundred meters long. The period of spawning in marine mollusks begins with the arrival of spring and lasts until the end of summer. Currently, oysters are bred artificially for industrial purposes. In this field, the undisputed leaders are France, the States and the Land of the Rising Sun.

The benefits of shellfish are also great in the prevention of cancer. However, they can even slow down, or even stop the process of developing a cancerous tumor. The reason is the antioxidant activity of numerous components of seafood. For example, a compound such as ceramide fats successfully fights breast cancer by blocking the growth of cancer cells in the bud. And yet, getting into the human body, the seafood accelerates the metabolism, eliminates the manifestations iron deficiency anemia promotes hematopoiesis.

To understand whether the delicacy suits you in this sense or not, you still have to try it - just don’t lean on the delicacy right away, stop at 1-2 things.

Like mussels, oysters are contraindicated for people with gout. The reason is the same: the extreme saturation of seafood with protein, which turns into uric acid in the internal environment of the human body, the salts of which, in turn, form crystalline deposits in the joints. The fair sex during pregnancy, lactation and people with diseases of the gastrointestinal tract should not feast on the delicacy. No one will benefit from eating bivalve mollusks without measure.

Oysters in cooking

Someone swallows the delicacy whole, while someone first gets rid of the muscles and gills, thanks to which the shell does not open spontaneously. However, this is not required. But it is very desirable to sprinkle the clams before sending them into the mouth with lemon juice and hold on ice - this measure will improve the taste of the delicacy.

Of course, live oysters are the most beneficial for the human body. But it is not forbidden to eat clams also stewed, boiled, fried, baked. Oysters cooked in batter or deep-fried are very tasty. The French traditionally eat seafood in combination with dry white wine and brown bread. The Dutch prefer light beer to wine.

Oysters are one of the most controversial delicacies in the world. For some, it is associated with a rich and carefree life, for others - with an incredible disgust that cannot be forgotten. Eminent culinary specialists admit that they hate all types of oysters and flatly refuse to cook them, and curious tourists eat clams one by one, counting the nutritional value and benefits.

Most mollusks live in tropical and subtropical climates. Their favorite place is the intertidal zone in shallow water and coastal zone. But some species lie 60 meters deep and prefer an isolated lifestyle.

Are oysters really that good and what is really hidden behind the massive gray doors?

Useful properties of seafood

Oysters are a real storehouse of cobalamin (). Human body is not able to independently generate B12, so you have to look for alternative sources of the vitamin. What causes B12 deficiency? The body sharply loses its tone, becomes lethargic and inoperable. A person becomes distracted, irritable, and a great desire to lie down and have a good sleep does not let go for the whole day. To ensure that the need to "lay low" does not ruin your productive week, replenish the balance of cobalamin.

The diet affects the organs of vision much more than computer glasses or constant relaxation exercises. Substances that make up healthy foods nourish different areas of the eye and prevent cataracts, night blindness, and macular degeneration.

Scientists have long proven the beneficial effects of certain groups of vitamins and amino acids on the condition of the skin. Most big organ The human body is most susceptible to both external and internal factors. Care and nutrition from the inside, rather than luxury cosmetics, makes the skin literally radiate beauty and health.

Oysters are a tasty source of ascorbic acid () and tocopherol (). They protect the dermis from ultraviolet radiation and minimize the effects of free radicals. Oysters prolong the youthfulness of the skin, relieve inflammation and treat existing imperfections.

Which also abounds in seafood, are responsible for the formation of the skin, hair follicles and nail plate. Retinol () controls the repair of damaged cells. But vitamins are not the only way oysters can please our skin. Omega-3-6 fatty acids nourish the skin several times better than any expensive mask. Omegas are responsible for an even tone, velvety structure and absolute purity of the dermis.

Another important element, the use of which may well replace a visit to a beautician, is zinc (Zn). It moisturizes not only the retina, but the entire skin.

The chemical composition of the ingredient

What danger do oysters hide in themselves?

The obvious danger lies not only in oysters, but in all seafood that lives in modern waterways. Under the dense flaps, not a friendly mollusk may be hiding, but dangerous mercury compounds. IN Lately environmentalists ring the bell and try to draw public attention to what is happening. The level of harmful mercury compounds is increasing every day. This is facilitated by every working mine, every gram of gold mined and every volcanic eruption.

Mercury enters the air, from there - into the waterways of the world. In the water itself, the concentration of mercury compounds is minimal. Oysters become infected through biomagnification. Due to trophic chains known from school, mercury gets into algae, and then to huge predatory fish. Such cross-contamination can indeed be detrimental to human health.

The use of seafood with methylmercury is fraught with:

neuralgic pathologies;
Alzheimer's disease;
Parkinson's disease;
disorders of the autistic sector;
depressive states;
level increase;
hypertension;
an increase in the risk of heart attacks and pathologies of the cardiovascular system.

List of possible side effects frightening and may suggest an idea to completely get rid of fish / seafood in the diet. But there is simply no replacement for easily digestible protein, useful amino acids and vitamins. In addition, scientists have proven that oysters are the least exposed to hazardous mercury compounds.

To protect yourself from methylmercury as much as possible, you must:

carefully choose a seafood supplier;
visit only those establishments in which there is a thorough control over the quality of products;
eat fish and seafood no more than 3 times a week.

Particular care will have to be taken by pregnant and lactating women. It is their body that is most susceptible to pathogenic changes and can literally receive a double blow.

Use in cooking

The clam ceased to be the embodiment of the royal aristocracy as soon as it moved to the menu of every second provincial restaurant. Consumers, realizing that there is nothing complicated in cooking oysters, decided to hold delicious meals right at home: in comfort and without extra expenses.

Clams are especially good for romantic dinners, as they are a powerful aphrodisiac (the product stimulates blood circulation). The action of the oyster is incomparable with the previously popular or "Mate". Take note and mentally thank the impartial mollusk for the wonderful continuation of the evening.

The first use of an oyster is always stressful. Taste buds do not understand what to expect, and inside everything shrinks from the understanding that in a second you will have to swallow a living being. But the desire to participate in gourmet conversations takes over. The delicate salty-sweet taste literally spreads through the receptors and stimulates one of 2 possible reactions: disgust or love.

In the classic version (especially in cozy French courtyards), homemade rye croutons and butter are served with oysters. A “clean” oyster (no sauce, just lemon juice is allowed) with a creamy toast is one of the best combinations in the world.

Depending on the variety of oysters, there are 3 main flavors:

sweet;
salty;
neutral.

The first two types are best eaten in their pure form, adding a slice. Neutral oysters are a white canvas for culinary experiments. They are served with various sauces, spices, fruits and vegetables. Usually, a whole range of flavors and aromas is presented to the client, and he is free to choose his favorite or an extraordinary new combination on his own.

Usually fresh oysters are served alive. The degree of vitality of an oyster is very easy to check. Slightly move the edge of the clam with a knife. The oyster will react with contractions of its entire body and return the retracted edge to its place.

But oysters are served not only fresh. They are baked in a tender dough, breaded until golden brown, grilled, seasoned with chopped spices.

How to eat shellfish

Stupor in front of oysters is a classic situation that is played out in many films, TV series, books and in all popular culture. Let's end this issue once and for all.

Where there is

You can eat everywhere: in an expensive restaurant, and in the kitchen of Khrushchev. The main thing is to choose a quality product. Order delivery from a trusted restaurant or from a responsible supplier who is ready to provide documents an extra 100 times. If you are going to an evening party, then carefully choose an institution. The consequences of stale oyster poisoning are truly nightmarish. A person feels sick for several days, working capacity decreases, and the desire to simply get out of bed does not appear on his own.

Stale clams open up in the water. If they brought you an already opened shell - demand a replacement or just proudly leave such an institution.

How much

Eat as much as you like. Keep in mind that oysters are quite satiating, so it's unlikely you'll want to try a few more items from the menu. For pure protein, it is best to order something light and stimulating digestion. Choose a vegetable salad without sauce and a lot of spices, steamed cereal or a small amount of seafood to complement the evening's marine theme.

Fatty carbohydrate dishes in combination with a shellfish will make a real explosion inside the body. It is better to refuse such experiments. It is much more pleasant to feel the effect of an aphrodisiac from oysters, rather than an upset bowel.

How to serve

Served on a crushed ice cushion to allow the clam to live another 15-20 minutes without water. During these 15 minutes, you need to have time to eat oysters while they are fresh and as healthy as possible. Difficulties with the speed of absorption should not arise, the main thing is to adapt and feel the taste. Along with an ice pillow, a set of spices, sauces and traditional rye toast with butter are served.

How to open

Oysters are taken out of a large aquarium with special tongs and served directly on the table. The shutters must be opened with a thin knife or a short blade (be guided by the set of devices that the institution has). For the first time, to be honest, the doors can simply be opened with your hands. No one will cast a reproachful glance at you, since everyone is busy with their own meal (and they themselves open oysters with their hands). But be careful not to hurt yourself and tear the clam inside.

As it is

Find a special fork on the table. Gently move it in the opened oyster (it is important not to spill the internal liquid) to separate the clam from the shell. In some restaurants, the mollusk is pre-cut, which makes the consumption process much easier. Once the clam is separated, add your favorite sauce or lemon wedge.

If the oyster is small, then in one fell swoop turn the shell over and pour the mollusk into yourself along with the liquid. If the sink is too big and you are afraid of choking, then eat gradually. First, remove the clam with a fork, eat it, and then drink the liquid from the shell.

After ingestion of the shellfish and liquid, eat another hot creamy toast, drink wine and feel like the richest aristocrat of our time.

A few more rules

Don't salt the oyster. It contains plenty of natural, so there is no need for additional replenishment. If you are afraid to hurt your hands or stain your suit, then ask the waiter for special rubber gloves for butchering. Prepare for the fact that cutting an oyster will require serious physical effort. Tune in, concentrate on the process and everything will go like clockwork.
