Laminaria, what do you know about it? The benefits and harms of seaweed for the body.

Sea kale is commonly called kelp, and there are about 30 species. Only cabbage leaves are considered edible. They contain many useful vitamins, and if you consume seaweed for at least a week, a person’s well-being and health will noticeably improve.

Initially, seaweed was harvested from the sea. But then, in order to protect the environment, we had to abandon this method of extraction. And now seaweed is grown on special plantations in Korea, Japan and China, artificially formed at the bottom of the sea. The stones are dipped in water so that they form a layer of soil on top of which the spores are dropped. Sometimes to form such a plantation there are rocks, the fragments of which become new soil for kelp.

Sea kale extraction process

In some areas, seaweed is still collected from the sea. For example, kelp is mined in the White Sea (near the Solovetsky Islands). People who prepare seaweed are called dergali. For work they use a special device - a dredge. It is used to cut off the seaweed growing at the bottom. Also, recently the Dergals have been using another tool - the cabea, which looks like a three-pronged fork. Using this device, cabbage is collected by twisting it onto a fork, like pasta.

This work is very hard, so only strong men are engaged in harvesting kelp. In good, clear weather, workers go out to sea twice a day to collect herbs. On average, a working day can last 15-18 hours. All this time they ride around on carabasses and collect grass from the bottom.

The next day, when the cabbage is dry, cut off the roots and remove dry algae. Drying seaweed is a rather problematic process, since collective farms usually do not have special equipment; seaweed is dried on hangers. And in rainy weather, kelp production decreases sharply.

After drying, the seaweed is sorted. The best ones are sold to various beauty salons for body wraps. That’s how cabbage is used there – whole, unprocessed leaves. The French are also very interested in Solovetsky sea kale due to the presence of a unique amount of polysarides in it.

Low-grade kelp is used for the needs of the food industry. Most often you can find them in a tin labeled “Seaweed Salad.”

Laminaria, or as it is also called - seaweed, is very useful. Both adults and children love her. Today we will talk about what it consists of, what its benefits are, why it is harmful and, of course, we will find out how seaweed grows.

Chemical composition of kelp

It depends on the temperature of the water where the algae lives, on its illumination and salinity. The composition of the healthy beauty will also depend on how it was prepared. Simple seaweed is low in calories. It contains only five calories per hundred grams of product. It contains 0.2 grams of fat and 0.9 grams of protein.

Cabbage is enriched with vitamin A, vitamins B1, B2, B6, B9, PP. It is rich in ascorbic acid and contains macroelements such as potassium, calcium, phosphorus, magnesium. Among the trace elements it contains iron and manganese. The first component is iodine. It contains the largest amount. That is why seaweed is recommended for people suffering from thyroid diseases. You're probably wondering how sea kale grows. More on this a little later, but now let's find out who first tasted these algae.

Useful properties of kelp

Sea kale is loved by the people of China. Initially they used it as a medicine, but after some time they realized that kelp fits perfectly into recipes for preparing a variety of dishes.

As already mentioned, the main advantage of cabbage is iodine. Moreover, it is completely absorbed by the body. This product is ideal for Russia, because it is in this country that most people suffer due to a lack of this component in the body. Iodine deficiency occurs in the North Caucasus, the Urals and the Middle Volga region. Where does sea kale grow in Russia?

Laminaria habitats

There are about thirty species of kelp. Of these, two are the most common. This is palmate and Japanese. In what sea does seaweed grow? The first is mined in our northern seas - the White, Barents and Kara. Japanese kelp lives in the Far East along the shores of the Sea of ​​Japan and the Sea of ​​Okhotsk. How does seaweed grow in these places? It consists of brown and greenish algae. We can say that it is similar to dense forests, only under water. Laminaria spreads over distances from three to forty meters.

Where is kelp used?

This brown algae is widely used in industry, in medicines and even as a fertilizer. Some people eat seaweed with great pleasure. It is characterized by special taste qualities that are formed due to the habitats of the algae. Where does seaweed grow? And it grows off the coast of seas and oceans. It has a variety of shapes and lengths. Some algae can be only a few centimeters long, while some can be up to twenty meters or more. Kelp is inexpensive because it is accessible and easy to obtain. Look at the photo of how seaweed grows.

It grows at a depth of 5 to 10 meters, but there have been cases when kelp was taken from greater depths - up to 40 meters. It is attached to the bottom with a disc-shaped sole or with the help of rhizoids.

What determines the type of algae?

It depends on how seaweed grows and where it lives. As already mentioned, Japanese kelp lives in the Far East in the Sea of ​​Japan and the Sea of ​​Okhotsk. Sugary algae can be found in the Kara and White Seas. A huge amount of seaweed is harvested, but, despite the industrial scale, it does not end there. Laminaria is very tenacious.

How does seaweed end up on the shelves of stores and pharmacies?

Laminaria is obtained in two ways:

  1. With the help of divers and special equipment, algae is extracted from the depths of the seas and oceans.
  2. They are collected from the shores after a storm washes seaweed ashore. But it should be remembered that it is suitable for production only if it has lain for no more than two days.

Laminaria is collected, washed in sea water, thereby clearing it of sand, and dried. Drying must be correct, because only then will the algae retain all its beneficial properties. Sometimes seaweed is frozen. In this form, it can be stored for six months, but it will retain only part of its beneficial properties.

Laminaria is used not only for food purposes, but also cosmetics and medicines are made from it.

How is seaweed good for women?

For ladies losing weight, this is just a godsend. As already mentioned, kelp is not only low-calorie, but also very beneficial for the body. It is used as wraps to combat cellulite, strengthen hair and rejuvenate the face.

Women who eat seaweed are less likely to suffer from infertility and breast cancer. Kelp contains a huge amount of folic acid, so pregnant mothers and those on the way to it, seaweed is a must.

What are the benefits for men?

It is useful for the stronger sex in all ways that it is for other people. In addition, kelp increases potency and libido, which has a beneficial effect on family life.

Is there any harm from eating seaweed?

You should not overuse it, as an excess can harm the body. Manifestations such as nervous excitability, nausea, and depression may appear. You should avoid eating kelp if you suffer from the following ailments:

  1. Hives.
  2. Kidney and liver diseases.
  3. Diathesis.
  4. Tuberculosis.

Difference between kelp and spirulina

Some people confuse these two algae, but there really is a difference between them. They have different shapes and sizes. Sea kale is much larger. They are both used for food, but, according to scientists, spirulina has more beneficial properties and has no contraindications.

The article told us how seaweed grows, whether it is worth eating, and how it is harvested. There is a lot to think about, and taste dishes based on seaweed, too.

It is difficult to overestimate the importance seaweed in nutrition. Man has been eating kelp since time immemorial. The first dishes from seaweed were prepared simply - the plant was boiled in water or broth and eaten immediately. Or dried and eaten within a few days. Sea kale salad is widely known. It is easy to prepare, can be stored for a long time, and contains a rich set of chemical elements necessary for the body. The availability, ease of obtaining and impressive beneficial properties of seaweed have provided it with excellent export opportunities. Currently, it can be found in any stores around the world. Even in canned form, it does not lose its medicinal and preventive properties. It is not expensive, so almost everyone can afford it.

Chemical composition kelp looks impressive. The algae contains iodine (iodine itself was discovered in it in 1811), manganese, bromine, zinc, magnesium, iron, potassium, phosphorus and a dozen other chemical elements, vitamins A, B, C, D, E, and polysaccharides. Carbohydrates - 60%, proteins - 13%, fats - 2%. Sea kale holds the lead among all food products in terms of the presence of iodine and sodium, potassium and magnesium. It is especially useful for children (although they are not particularly fond of it). Laminaria is the main prevention of thyroid diseases (but for people with hypersensitivity to iodine, seaweed is contraindicated!). It increases the tone of the body, inhibits the development of vascular sclerosis, reduces the risk of developing blood clots, normalizes digestive and metabolic processes, and improves the immune system. Sea kale is a powerful aphrodisiac and is recommended to be consumed for sexual dysfunction in both men and women.


Laminaria has also been used in cosmetology. It is included in some cosmetics, infusions and ointments. Seaweed wrapping is also practiced, which has a general rejuvenating effect on the body. Used as a hair strengthening agent. In medicine, algae is used as an ingredient in iodine-containing preparations aimed at preventing atherosclerosis and goiter.

Laminaria grows everywhere in temperate and cold waters. Japan holds the leadership in the extraction and processing of algae. For residents of the Land of the Rising Sun, seaweed is a favorite basis for a huge number of dishes. It is used in the preparation of soups, meat dishes, salads, etc. Every year the Japanese eat several tens of thousands of tons of seaweed. This partly explains why there are so few scrofulous diseases and goiters and such a high life expectancy.

In Russia, seaweed is harvested in the northern and Far Eastern waters by mowing or dredging (using trawls), and algae washed ashore are also collected. Before the outbreak of World War I, Russia purchased iodine from Germany. But with hostilities, supplies from the enemy state were suspended, and the need for iodine, as a good disinfectant, only increased. Therefore, the first algae processing plants were built in the Far East and Arkhangelsk.

The most useful is considered to be seaweed obtained in cold northern waters. It retains more iodine and other beneficial substances. The seaweed processing process is still manual. Laminaria raised from the bottom of the sea is dried naturally, in the fresh air. Various “dryers” only harm the plant. Most of the resulting cabbage is canned right on site, this is how it best preserves its quality and does not deteriorate during transportation.

Many recipes for weight loss contain recommendations for eating seaweed.

Similar advice, but with the aim of maintaining general health and preventing diseases, is contained in ancient treatises on Feng Shui.

It is especially recommended for use by people of the Earth element.
